I have added the custom view in Map when user tap on the Pin maker in the map it will show the uiview ontop of the pin maker but the problem is when i scroll the Map the custom is not scrolling with the map pin please tell me how to resolve this issue.
My code.
-(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
test = [[UIView alloc]initWithFrame:CGRectMake(view.frame.origin.x - 12.5, view.frame.origin.y - 45, 50, 50)];
test.backgroundColor = [UIColor yellowColor];
[mpview addSubview:test];
}
-(void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view
{
test.frame = CGRectZero;
}
I have used the above code please tell me how to make the view to scroll with the pin maker in map
Thanks in Advance.
In this case you should add the test not to mapView but to the selected annotation view. Just update the position until it fit your needs.
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view {
test = [[UIView alloc]initWithFrame:CGRectMake(-10,-25, 50, 50)];
[view addSubview:test];
}
don´t forget to remove the view when you don`t need it anymore.

Is there any way to resize the large annotation as same as the left ones.It is iOS11 behaviour and I want the unique size for all annotations like before.
Thanks in advance
This is what I have done for my project
In delegate method
- (MKAnnotationView *) mapView:(MKMapView *)mapView1 viewForAnnotation:(id <MKAnnotation>) annotation
1) create the annotation view
MKAnnotationView *annView = [[MKAnnotationView alloc] initWithAnnotation:currentAnnotation reuseIdentifier:#"Cluster"];
2) set the frame and other properties
[annView setFrame:CGRectMake(0, 0,100,100)]; //(Important)
annView.canShowCallout = YES;
[annView setCenterOffset:CGPointMake(0, -18)];
3) add image view as sub view with same frame size
UIImageView *homeImage = [[UIImageView alloc] initWithImage:[UIImage cachedImage:#"GroupPin"]];
[homeImage setFrame:CGRectMake(0, 0,100,100)]; //(Important)
[annView addSubview:homeImage];
return annView;
and you are done.
I am trying to create an custom marker for Google Map, but my code is giving me a weird view with space, as the image bellow:
What is that white view? How to remove it? It was supposed to be only the red one!
-(UIView *)mapView:(GMSMapView *)mapView markerInfoContents:(GMSMarker *)marker{
UIView *infoView = [UIView new];
infoView.frame = CGRectMake(0, 0, 290, 192);
// Setting the bg as red just to illustrate
infoView.backgroundColor = [UIColor redColor];
return infoView;
}
I might be a bit rusty but isn't that the wrong function?
There is a markerInfoWindow and a markerInfoContents (which you are using).
The window is the whole thing whereas the contents is a view, which will be placed within the default info window frame
take a look here
The reason behind this white background is that you are using a wrong delegate method. Replace your code with this one:
-(UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker{
UIView *infoView = [UIView new];
infoView.frame = CGRectMake(0, 0, 290, 192);
// Setting the bg as red just to illustrate
infoView.backgroundColor = [UIColor redColor];
return infoView;
}
When I choose from a tableView, it goes back to my map and display the custom annotation callout over the pin selected. If I tap on another pin on the map, the custom callout view disappears from from the previous pin and is displayed over the current one selected.
If i try to tap inside the custom calloutView it also disappears. How can I avoid this, and why does this happen?
Here is the code:
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
if (![view.annotation isKindOfClass:[MKUserLocation class]]) {
self.calloutView = [[TNCalloutView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 150.0f, 100.0f)];
self.calloutView.alpha = 1.0f;
self.calloutView.backgroundColor = [UIColor whiteColor];
self.calloutView.layer.cornerRadius = 10.0f;
CGRect calloutViewFrame = self.calloutView.frame;
calloutViewFrame.origin = CGPointMake(-calloutViewFrame.size.width/2 + 20 , -calloutViewFrame.size.height -10);
self.calloutView.frame = calloutViewFrame;
[view addSubview:self.calloutView];
}
}
- (void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view
{
if ([view.annotation isKindOfClass:[TNAnnotations class]]) {
for (UIView *subviews in view.subviews) {
[subviews removeFromSuperview];
}
}
}
If I remove the deselect method all together. Nothing ever goes away, and that's not what I want.
Also, I have checked out other posts about this very topic, but it didn't help me.
Cheers.
I'm developing app, where user is localized by gps and then he is asked, whether he is located in specific place. To confirm this, callout bubble is presented to him straight away, asking him, if he is at specific place.
As there is alot of similar questions, I was able to do custom callout bubble:
My problem: button is not "clickable"
My guess: because this custom callout is higher than standard callout bubble, I had to place it in negative "frame", therefore button cannot be clicked. Here is my didSelectAnnotationView method
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view {
if(![view.annotation isKindOfClass:[MKUserLocation class]]) {
CalloutView *calloutView = (CalloutView *)[[[NSBundle mainBundle] loadNibNamed:#"callOutView" owner:self options:nil] objectAtIndex:0];
CGRect calloutViewFrame = calloutView.frame;
calloutViewFrame.origin = CGPointMake(-calloutViewFrame.size.width/2 + 15, -calloutViewFrame.size.height);
calloutView.frame = calloutViewFrame;
[calloutView.calloutLabel setText:[(MyLocation*)[view annotation] title]];
[calloutView.btnYes addTarget:self
action:#selector(checkin)
forControlEvents:UIControlEventTouchUpInside];
calloutView.userInteractionEnabled = YES;
view.userInteractionEnabled = YES;
[view addSubview:calloutView];
}
}
CalloutView is just simple class with 2 properties(label that shows name of place and button) and with xib.
I have been doing this custom callout bubble for a few days. I tried using "asynchrony solutions" solution but I was unable to add any other kind of button then disclosure button.
My next attempt, was to find something that was easier than asynchrony solutions and modify it to my use. Thats how I found tochi's custom callout.
Based on his work, I was able to customize his bubble and change info button for my custom button. My problem however remained the same. In order to place my custom callout view on top of the pin, I had to give it negative frame, so my button was "clickable" only in bottom 5 pixels. It seems, that I have to maybe dig deeper into ios default callout bubble, subclass it and change frame of callout in there. But I'm really hopeless now.
If you guys could show me the right way, or give me advice, I'll be glad.
There are several approaches to customizing callouts:
The easiest approach is to use the existing right and left callout accessories, and put your button in one of those. For example:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
static NSString *identifier = #"MyAnnotationView";
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
MKPinAnnotationView *view = (id)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (view) {
view.annotation = annotation;
} else {
view = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
view.canShowCallout = true;
view.animatesDrop = true;
view.rightCalloutAccessoryView = [self yesButton];
}
return view;
}
- (UIButton *)yesButton {
UIImage *image = [self yesButtonImage];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, image.size.width, image.size.height); // don't use auto layout
[button setImage:image forState:UIControlStateNormal];
[button addTarget:self action:#selector(didTapButton:) forControlEvents:UIControlEventPrimaryActionTriggered];
return button;
}
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
NSLog(#"%s", __PRETTY_FUNCTION__);
}
That yields:
If you really don't like the button on the right, where accessories generally go, you can turn off that accessory, and iOS 9 offers the opportunity to specify the detailCalloutAccessoryView, which replaces the callout's subtitle with whatever view you want:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
static NSString *identifier = #"MyAnnotationView";
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
MKPinAnnotationView *view = (id)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (view) {
view.annotation = annotation;
} else {
view = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
view.canShowCallout = true;
view.animatesDrop = true;
}
view.detailCalloutAccessoryView = [self detailViewForAnnotation:annotation];
return view;
}
- (UIView *)detailViewForAnnotation:(PlacemarkAnnotation *)annotation {
UIView *view = [[UIView alloc] init];
view.translatesAutoresizingMaskIntoConstraints = false;
UILabel *label = [[UILabel alloc] init];
label.text = annotation.placemark.name;
label.font = [UIFont systemFontOfSize:20];
label.translatesAutoresizingMaskIntoConstraints = false;
label.numberOfLines = 0;
[view addSubview:label];
UIButton *button = [self yesButton];
[view addSubview:button];
NSDictionary *views = NSDictionaryOfVariableBindings(label, button);
[view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:#"H:|[label]|" options:0 metrics:nil views:views]];
[view addConstraint:[NSLayoutConstraint constraintWithItem:button attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:view attribute:NSLayoutAttributeCenterX multiplier:1 constant:0]];
[view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:#"V:|[label]-[button]|" options:0 metrics:nil views:views]];
return view;
}
- (UIButton *)yesButton {
UIImage *image = [self yesButtonImage];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.translatesAutoresizingMaskIntoConstraints = false; // use auto layout in this case
[button setImage:image forState:UIControlStateNormal];
[button addTarget:self action:#selector(didTapButton:) forControlEvents:UIControlEventPrimaryActionTriggered];
return button;
}
This yields:
If you really want to develop a custom callout yourself, the Location and Maps Programming Guide outlines the steps involved:
In an iOS app, it’s good practice to use the mapView:annotationView:calloutAccessoryControlTapped: delegate method to respond when users tap a callout view’s control (as long as the control is a descendant of UIControl). In your implementation of this method you can discover the identity of the callout view’s annotation view so that you know which annotation the user tapped. In a Mac app, the callout view’s view controller can implement an action method that responds when a user clicks the control in a callout view.
When you use a custom view instead of a standard callout, you need to do extra work to make sure your callout shows and hides appropriately when users interact with it. The steps below outline the process for creating a custom callout that contains a button:
Design an NSView or UIView subclass that represents the custom callout. It’s likely that the subclass needs to implement the drawRect: method to draw your custom content.
Create a view controller that initializes the callout view and performs the action related to the button.
In the annotation view, implement hitTest: to respond to hits that are outside the annotation view’s bounds but inside the callout view’s bounds, as shown in Listing 6-7.
In the annotation view, implement setSelected:animated: to add your callout view as a subview of the annotation view when the user clicks or taps it.
If the callout view is already visible when the user selects it, the setSelected: method should remove the callout subview from the annotation view (see Listing 6-8).
In the annotation view’s initWithAnnotation: method, set the canShowCallout property to NO to prevent the map from displaying the standard callout when the user selects the annotation.
While it's in Swift, https://github.com/robertmryan/CustomMapViewAnnotationCalloutSwift illustrates an example of how you can do this complete customization of the callout (e.g. change shape of callout bubble, change background color, etc.).
That previous point outlines a pretty complicated scenarios (i.e. you have to write your own code to detecting taps outside the view in order to dismiss the it). If you're supporting iOS 9, you might just use a popover view controller, e.g.:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
static NSString *identifier = #"MyAnnotationView";
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
MKPinAnnotationView *view = (id)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (view) {
view.annotation = annotation;
} else {
view = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
view.canShowCallout = false; // note, we're not going to use the system callout
view.animatesDrop = true;
}
return view;
}
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view {
PopoverController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"AnnotationPopover"];
controller.modalPresentationStyle = UIModalPresentationPopover;
controller.popoverPresentationController.sourceView = view;
// adjust sourceRect so it's centered over the annotation
CGRect sourceRect = CGRectZero;
sourceRect.origin.x += [mapView convertCoordinate:view.annotation.coordinate toPointToView:mapView].x - view.frame.origin.x;
sourceRect.size.height = view.frame.size.height;
controller.popoverPresentationController.sourceRect = sourceRect;
controller.annotation = view.annotation;
[self presentViewController:controller animated:TRUE completion:nil];
[mapView deselectAnnotation:view.annotation animated:true]; // deselect the annotation so that when we dismiss the popover, the annotation won't still be selected
}
I wound up taking a different approach. I tried the others but they seemed bloated and I didn't want to add more classes or rely on the MKMapViewDelegate to handle the interaction.
I instead override setSelected:animated of my MKAnnotationView subclass. The trick is to expand the bounds of the annotationView after it it selected to fully encompass the call out view, and then return them back to normal after it is deselected. This will allow your custom call outs to accept touches and interactions outside the original bounds of the MKAnnotationView.
Here is a trimmed down code sample to get anyone started:
#define kAnnotationCalloutBoxTag 787801
#define kAnnotationCalloutArrowTag 787802
#define kAnnotationTempImageViewTag 787803
-(void)setSelected:(BOOL)selected animated:(BOOL)animated
{
if (selected == self.selected)
{
NSLog(#"annotation already selected, abort!");
return;
}
if (selected)
{
self.image = nil; //hide default image otherwise it takes the shape of the entire bounds
UIView* calloutBox = [self newCustomCallout];
float imgW = [self unselectedSize].width;
float imgH = [self unselectedSize].height;
float arrowW = 20;
float arrowH = 12;
//Annotation frames wrap a center coordinate, in this instance we want the call out box to fall under the
//central coordinate, so we need to adjust the height to be double what the callout box height would be
//making the height *2, this is to make sure the callout view is inside of it.
self.bounds = CGRectMake(0, 0, calloutBox.frame.size.width, calloutBox.frame.size.height*2 + arrowH*2 + imgH);
CGPoint center = CGPointMake(self.bounds.size.width/2, self.bounds.size.height/2);
UIView* imgView = [[UIImageView alloc] initWithImage:icon];
[imgView setFrame:CGRectMake(center.x - imgW/2, center.y-imgH/2, imgW, imgH)];
imgView.tag = kAnnotationTempImageViewTag;
[self addSubview:imgView];
UIView* triangle = [self newTriangleViewWithFrame:CGRectMake(center.x-arrowW/2, center.y+imgH/2, arrowW, arrowH)];
triangle.tag = kAnnotationCalloutArrowTag;
[self addSubview:triangle];
[calloutBox setFrame:CGRectMake(0, center.y+imgH/2+arrowH, calloutBox.width, calloutBox.height)];
calloutBox.tag = kAnnotationCalloutBoxTag;
[self addSubview:calloutBox];
}
else
{
//return things back to normal
UIView* v = [self viewWithTag:kAnnotationCalloutBoxTag];
[v removeFromSuperview];
v = [self viewWithTag:kAnnotationCalloutArrowTag];
[v removeFromSuperview];
v = [self viewWithTag:kAnnotationTempImageViewTag];
[v removeFromSuperview];
self.image = icon;
self.bounds = CGRectMake(0, 0, [self unselectedSize].width, [self unselectedSize].height);
}
[super setSelected:selected animated:animated];
}
-(CGSize)unselectedSize
{
return CGSizeMake(20,20);
}
-(UIView*)newCustomCallout
{
//create your own custom call out view
UIView* v = [[UIView alloc] initWithFrame:CGRectMake(0,0,250,250)];
v.backgroundColor = [UIColor greenColor];
return v;
}
-(UIView*)newTriangleWithFrame:(CGRect)frame
{
//create your own triangle
UIImageView* v = [[UIImageView alloc] initWithFrame:frame];
[v setImage:[UIImage imageNamed:#"trianglePointedUp.png"]];
return v;
}
(void)mapView:(MKMapView *)mapViewIn didSelectAnnotationView:(MKAnnotationView *)view {
if(![view.annotation isKindOfClass:[MKUserLocation class]])
{
CustomeCalloutViewController *calloutView = [[CustomeCalloutViewController alloc]initWithNibName:#"CustomeCalloutViewController" bundle:nil];
[calloutView setPopinTransitionStyle:BKTPopinTransitionStyleSlide];
[calloutView setPopinTransitionDirection:BKTPopinTransitionDirectionTop];
[self presentPopinController:calloutView animated:YES completion:^{
NSLog(#"Popin presented !");
}];
[mapView deselectAnnotation:view.annotation animated:true];
}
}
I'm currently working with the mapkit and am stuck.
I have a custom annotation view I am using, and I want to use the image property to display the point on the map with my own icon. I have this working fine. But what I would also like to do is to override the default callout view (the bubble that shows up with the title/subtitle when the annotation icon is touched). I want to be able to control the callout itself: the mapkit only provides access to the left and right ancillary callout views, but no way to provide a custom view for the callout bubble, or to give it zero size, or anything else.
My idea was to override selectAnnotation/deselectAnnotation in my MKMapViewDelegate, and then draw my own custom view by making a call to my custom annotation view. This works, but only when canShowCallout is set to YES in my custom annotation view class. These methods are NOT called if I have this set to NO (which is what I want, so that the default callout bubble is not drawn). So I have no way of knowing if the user touched on my point on the map (selected it) or touched a point that is not part of my annotation views (delected it) without having the default callout bubble view show up.
I tried going down a different path and just handling all touch events myself in the map, and I can't seem to get this working. I read other posts related to catching touch events in the map view, but they aren't exactly what I want. Is there a way to dig into the map view to remove the callout bubble before drawing? I'm at a loss.
Any suggestions? Am I missing something obvious?
There is an even easier solution.
Create a custom UIView (for your callout).
Then create a subclass of MKAnnotationView and override setSelected as follows:
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
if(selected)
{
//Add your custom view to self...
}
else
{
//Remove your custom view...
}
}
Boom, job done.
detailCalloutAccessoryView
In the olden days this was a pain, but Apple has solved it, just check the docs on MKAnnotationView
view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
view.canShowCallout = true
view.detailCalloutAccessoryView = UIImageView(image: UIImage(named: "zebra"))
Really, that's it. Takes any UIView.
Continuing on from #TappCandy's brilliantly simple answer, if you want to animate your bubble in the same way as the default one, I've produced this animation method:
- (void)animateIn
{
float myBubbleWidth = 247;
float myBubbleHeight = 59;
calloutView.frame = CGRectMake(-myBubbleWidth*0.005+8, -myBubbleHeight*0.01-2, myBubbleWidth*0.01, myBubbleHeight*0.01);
[self addSubview:calloutView];
[UIView animateWithDuration:0.12 delay:0.0 options:UIViewAnimationOptionCurveEaseOut animations:^(void) {
calloutView.frame = CGRectMake(-myBubbleWidth*0.55+8, -myBubbleHeight*1.1-2, myBubbleWidth*1.1, myBubbleHeight*1.1);
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^(void) {
calloutView.frame = CGRectMake(-myBubbleWidth*0.475+8, -myBubbleHeight*0.95-2, myBubbleWidth*0.95, myBubbleHeight*0.95);
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.075 animations:^(void) {
calloutView.frame = CGRectMake(-round(myBubbleWidth/2-8), -myBubbleHeight-2, myBubbleWidth, myBubbleHeight);
}];
}];
}];
}
It looks fairly complicated, but as long as the point of your callout bubble is designed to be centre-bottom, you should just be able to replace myBubbleWidth and myBubbleHeight with your own size for it to work. And remember to make sure your subviews have their autoResizeMask property set to 63 (i.e. "all") so that they scale correctly in the animation.
:-Joe
Found this to be the best solution for me.
You'll have to use some creativity to do your own customizations
In your MKAnnotationView subclass, you can use
- (void)didAddSubview:(UIView *)subview{
int image = 0;
int labelcount = 0;
if ([[[subview class] description] isEqualToString:#"UICalloutView"]) {
for (UIView *subsubView in subview.subviews) {
if ([subsubView class] == [UIImageView class]) {
UIImageView *imageView = ((UIImageView *)subsubView);
switch (image) {
case 0:
[imageView setImage:[UIImage imageNamed:#"map_left"]];
break;
case 1:
[imageView setImage:[UIImage imageNamed:#"map_right"]];
break;
case 3:
[imageView setImage:[UIImage imageNamed:#"map_arrow"]];
break;
default:
[imageView setImage:[UIImage imageNamed:#"map_mid"]];
break;
}
image++;
}else if ([subsubView class] == [UILabel class]) {
UILabel *labelView = ((UILabel *)subsubView);
switch (labelcount) {
case 0:
labelView.textColor = [UIColor blackColor];
break;
case 1:
labelView.textColor = [UIColor lightGrayColor];
break;
default:
break;
}
labelView.shadowOffset = CGSizeMake(0, 0);
[labelView sizeToFit];
labelcount++;
}
}
}
}
And if the subview is a UICalloutView, then you can screw around with it, and what's inside it.
I had the same problem. There is a serious of blog posts about this topic on this blog http://spitzkoff.com/craig/?p=81.
Just using the MKMapViewDelegate doesn't help you here and subclassing MKMapView and trying to extend the existing functionality also didn't work for me.
What I ended up doing is to create my own CustomCalloutView that I am having on top of my MKMapView. You can style this view in any way you want.
My CustomCalloutView has a method similar to this one:
- (void) openForAnnotation: (id)anAnnotation
{
self.annotation = anAnnotation;
// remove from view
[self removeFromSuperview];
titleLabel.text = self.annotation.title;
[self updateSubviews];
[self updateSpeechBubble];
[self.mapView addSubview: self];
}
It takes an MKAnnotation object and sets its own title, afterward it calls two other methods which are quite ugly which adjust the width and size of the callout contents and afterward draw the speech bubble around it at the correct position.
Finally the view is added as a subview to the mapView. The problem with this solution is that it is hard to keep the callout at the correct position when the map view is scrolled. I am just hiding the callout in the map views delegate method on a region change to solve this problem.
It took some time to solve all those problems, but now the callout almost behaves like the official one, but I have it in my own style.
Basically to solve this, one needs to:
a) Prevent the default callout bubble from coming up.
b) Figure out which annotation was clicked.
I was able to achieve these by:
a) setting canShowCallout to NO
b) subclassing, MKPinAnnotationView and overriding the touchesBegan and touchesEnd methods.
Note: You need to handle the touch events for the MKAnnotationView and not MKMapView
I just come up with an approach, the idea here is
// Detect the touch point of the AnnotationView ( i mean the red or green pin )
// Based on that draw a UIView and add it to subview.
- (void)mapView:(MKMapView *)mapView regionWillChangeAnimated:(BOOL)animated
{
CGPoint newPoint = [self.mapView convertCoordinate:selectedCoordinate toPointToView:self.view];
// NSLog(#"regionWillChangeAnimated newPoint %f,%f",newPoint.x,newPoint.y);
[testview setCenter:CGPointMake(newPoint.x+5,newPoint.y-((testview.frame.size.height/2)+35))];
[testview setHidden:YES];
}
- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
CGPoint newPoint = [self.mapView convertCoordinate:selectedCoordinate toPointToView:self.view];
// NSLog(#"regionDidChangeAnimated newPoint %f,%f",newPoint.x,newPoint.y);
[testview setCenter:CGPointMake(newPoint.x,newPoint.y-((testview.frame.size.height/2)+35))];
[testview setHidden:NO];
}
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
NSLog(#"Select");
showCallout = YES;
CGPoint point = [self.mapView convertPoint:view.frame.origin fromView:view.superview];
[testview setHidden:NO];
[testview setCenter:CGPointMake(point.x+5,point.y-(testview.frame.size.height/2))];
selectedCoordinate = view.annotation.coordinate;
[self animateIn];
}
- (void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view
{
NSLog(#"deSelect");
if(!showCallout)
{
[testview setHidden:YES];
}
}
Here - testview is a UIView of size 320x100 - showCallout is BOOL - [self animateIn]; is the function that does view animation like UIAlertView.
You can use leftCalloutView, setting annotation.text to #" "
Please find below the example code:
pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if(pinView == nil){
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
}
CGSize sizeText = [annotation.title sizeWithFont:[UIFont fontWithName:#"HelveticaNeue" size:12] constrainedToSize:CGSizeMake(150, CGRectGetHeight(pinView.frame)) lineBreakMode:UILineBreakModeTailTruncation];
pinView.canShowCallout = YES;
UILabel *lblTitolo = [[UILabel alloc] initWithFrame:CGRectMake(2,2,150,sizeText.height)];
lblTitolo.text = [NSString stringWithString:ann.title];
lblTitolo.font = [UIFont fontWithName:#"HelveticaNeue" size:12];
lblTitolo.lineBreakMode = UILineBreakModeTailTruncation;
lblTitolo.numberOfLines = 0;
pinView.leftCalloutAccessoryView = lblTitolo;
[lblTitolo release];
annotation.title = #" ";
I've pushed out my fork of the excellent SMCalloutView that solves the issue with providing a custom view for callouts and allowing flexible widths/heights pretty painlessly. Still some quirks to work out, but it's pretty functional so far:
https://github.com/u10int/calloutview
