Add UIbutton event in custom callout view in MapView Objective C - ios

Question

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
MKAnnotationView *view = [self.mapView dequeueReusableAnnotationViewWithIdentifier:#"loc"];
return view;
}
- (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views {
for (MKAnnotationView *annotationView in views) {
annotationView.canShowCallout = NO;
}
}
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view {
MAKRCalloutView *calloutView = [[MAKRCalloutView alloc] initWithNibName:#"ViewM" bundle:nil];
UIButton *btn = [[UIButton alloc]initWithFrame:CGRectMake(10.0, 10.0, 50.0, 50.0)];
[btn setBackgroundColor:[UIColor redColor]];
[btn addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[view addSubview:calloutView.view];
[view addSubview:btn];
}
-(void) buttonClicked:(id)sender{
NSLog(#" %ld button click %# ", (long)[sender tag]);
}
- (void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view {
for (UIView *subview in view.subviews) {
MAKRCalloutView *calloutView = [[MAKRCalloutView alloc] initWithNibName:#"ViewM" bundle:nil];
if (![subview isKindOfClass:[calloutView.view class]]) {
continue;
}
[subview removeFromSuperview];
}
}
I cannot call get button click event. Even I cannot click on button also. I want to go at other UIViewController by click on button.
I have also tried UITapGestureRecognizer. But its limited to Pin area only.

Answer 1

[button addTarget:self action:#selector(clickEvent) forControlEvents:UIControlEventTouchDown]
And then
- (CustomAnnotationView *)mapView:(MKMapView *)aMapView viewForAnnotation:(id <MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[CustomAnnotation class]])
{
CustomAnnotationView *newAnnotationView = nil;
// determine the type of annotation, and produce the correct type of annotation view for it.
newAnnotationView = [[[CustomAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:nil delegate: targetController] autorelease];
[newAnnotationView setEnabled:YES];
[newAnnotationView setCanShowCallout:NO];
return newAnnotationView;
}
}
#interface CustomAnnotationView : MKAnnotationView
{
}
#end
#implementation CustomAnnotationView
- (id)initWithAnnotation:(id <MKAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier delegate:(id)targetController
{
self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier];
/* Set initial width as you want. ex: 50X50*/
self.frame = CGRectMake(0, 0, Initial_width, Initial_height);
self.backgroundColor = [UIColor redColor];
return self;
}
/* When you tap on an annotation this method is fired*/
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
if(selected){
/* When you select annotation, instead of showing default callout you can increase the width &height of annotation and add your custom view here*/
self.frame = CGRectMake(0, 0, max_width, max_height);
UIView *view = [[UIView alloc]initWithFrame:CGRectMake(6, 0, max_width-10, max_height)];
view.backgroundColor = [UIColor blackColor];
UIButton *but = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *img = [UIImage imageNamed:#"image.png"];
but = CGRectMake(x , y, img.size.width + 20, img.size.height + 15);
[but setImage:img forState:UIControlStateNormal];
[but addTarget:targetController action:#selector(methodName) forControlEvents:UIControlEventTouchDown];
[view addSubview:but];
[self addSubview:view];
}
else {
/* When you tap outside of annotation, set the initial frame for the annotation. and remove the custom view from annotation*/
self.frame = CGRectMake(0, 0, Initial_width, Initial_height);
[view removeFromSuperview];
}
