UIButton is not working on didSelectAnnotationView - ios

Question

Hi I have custom view in didSelectAnnotationView when user tap on the pin maker I'm displaying the custom view with UILabel and a UIButton everything is working fine but the UIButton is not clickable please tell how to resolve this issue.
My code.
-(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view1
{
NSString *bult;
if ([view1.annotation isKindOfClass:[MapPin class]]) {
MapPin *annot = view1.annotation;
NSLog(#"tit%#",annot.nsname);
bult=annot.nsname;
}
myview = [[UIView alloc]initWithFrame:CGRectMake(-60, -110, 200, 100)];
myview.layer.cornerRadius = 10;
myview.backgroundColor = [UIColor yellowColor];
myview.userInteractionEnabled = YES;
[view1 addSubview:test];
buldingname = [[UILabel alloc] initWithFrame:CGRectMake(5, -15, 150, 80)];
buldingname.text=bult;
[buldingname setTextColor:[UIColor blackColor]];
[buldingname setBackgroundColor:[UIColor clearColor]];
[buldingname setFont:[UIFont fontWithName: #"Trebuchet MS" size: 14.0f]];
buldingname.lineBreakMode = NSLineBreakByWordWrapping;
buldingname.numberOfLines = 3;
[myview addSubview:buldingname];
moredetail=[UIButton buttonWithType:UIButtonTypeRoundedRect];
moredetail.frame= CGRectMake(0, 55, 200, 50);
[moredetail setTitle:#"Click here for more details" forState:UIControlStateNormal];
[moredetail addTarget:self action:#selector(nextbtn:) forControlEvents:UIControlEventTouchUpInside];
[moredetail setExclusiveTouch:YES];
[myview addSubview:moredetail];
}
My calling method.
- (IBAction)nextbtn:(id)sender
{
NSLog(#"click");
}
I have used the above code its not working please tell me where I'm doing wrong how to resolve this issue.
Thanks in Advance.

Answer 1

It is not working because the mapView still handles the touch event.
Just add an DetailView in the:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[MKUserLocation class]])
{
return nil;
}
static NSString *reuseIdentifier = #"Your_identifier";
MKAnnotationView *view = [mapView dequeueReusableAnnotationViewWithIdentifier:reuseIdentifier];
if (view == nil)
{
view = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:reuseIdentifier];
view.image = [UIImage imageNamed:#"your_annotaion_image.png"];
}
view.canShowCallout = YES;
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:#selector(showDetails:) forControlEvents:UIControlEventTouchUpInside];
view.rightCalloutAccessoryView = rightButton;
UIImageView *icon = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"your_icon_image"]];
view.leftCalloutAccessoryView = icon;
return view;
}
and then you can call:
-(void)showDetails:(UIButton*)button
{
//do your stuff here
}
there is absolutely no need to build a annotation callout view yourself, just change the design of the default one.

You need to be add sub view to your custom view then its work.
-(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view1
{
NSString *bult;
if ([view1.annotation isKindOfClass:[MapPin class]]) {
MapPin *annot = view1.annotation;
NSLog(#"tit%#",annot.nsname);
bult=annot.nsname;
}
myview = [[UIView alloc]initWithFrame:CGRectMake(-60, -110, 200, 100)];
myview.layer.cornerRadius = 10;
myview.backgroundColor = [UIColor yellowColor];
myview.userInteractionEnabled = YES;
[view1 addSubview:myview];
buldingname = [[UILabel alloc] initWithFrame:CGRectMake(5, -15, 150, 80)];
buldingname.text=bult;
[buldingname setTextColor:[UIColor blackColor]];
[buldingname setBackgroundColor:[UIColor clearColor]];
[buldingname setFont:[UIFont fontWithName: #"Trebuchet MS" size: 14.0f]];
buldingname.lineBreakMode = NSLineBreakByWordWrapping;
buldingname.numberOfLines = 3;
[myview addSubview:buldingname];
moredetail=[UIButton buttonWithType:UIButtonTypeRoundedRect];
moredetail.frame= CGRectMake(0, 55, 200, 50);
[moredetail setTitle:#"Click here for more details" forState:UIControlStateNormal];
[moredetail addTarget:self action:#selector(nextbtn:) forControlEvents:UIControlEventTouchUpInside];
[moredetail setExclusiveTouch:YES];
[myview addSubview:moredetail];
}
