I want to show a custom callout with two button , and I also want action on both buttons ,
I try that but not do this type of callout on map, this isn't really exactly what I wanted. As I am making an iPhone application, Since I am new to MKMapview its getting difficult for me to do the same. How to show custom callout with two button?
You can go for Left and right calloutaccessoryview Look at HERE
//ANNOTATION VIEW SETTING DELEGATE
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{
MKPinAnnotationView *myPin = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:#"reuseString"];
myPin.draggable = NO;
myPin.canShowCallout = YES;
myPin.pinColor = MKPinAnnotationColorRed;
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeCustom];
rightButton.frame = CGRectMake(0, 0, 50, 30);
[rightButton setTitle:#"Info!" forState:UIControlStateNormal];
[rightButton setBackgroundImage:[UIImage imageNamed:#"image.png"] forState:UIControlStateNormal];
rightButton.showsTouchWhenHighlighted = YES;
[rightButton addTarget:self action:#selector(rightAcccoryViewButtonCLicked) forControlEvents:UIControlEventTouchUpInside]; //rightAcccoryViewButtonCLicked is a function
myPin.rightCalloutAccessoryView = rightButton;
return myPin;
}
Similarly you can use the leftCalloutAccessoryView and add another button.

I have to display custom view on annotation click in ios, I have to display 7 images, name and detail disclosure button in custom view. On click of detail disclosure button , i have to call new view controller. How should i do it?
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
// Define your reuse identifier.
MKPinAnnotationView *annotationView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"currentloc"];
annotationView.pinColor = MKPinAnnotationColorGreen;
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
// Adding Button on annotation callout which is your detail disclosure button//
UIButton *rightButton = [[UIButton alloc]initWithFrame:CGRectMake(0.0f,0.0f,28.0f,22.0f)];
[rightButton setImage:[UIImage imageNamed:#"rightArrow.png"] forState:UIControlStateNormal];
[rightButton addTarget:self
action:#selector(pressDetailBtn:)
forControlEvents:UIControlEventTouchUpInside];
annotationView.rightCalloutAccessoryView = rightButton;
annotationView.image=[UIImage imageNamed:#"orangePin.png"];
annotationView.opaque = NO;
return annotationView;
}
-(void)pressDetailBtn:(id)sender

I'm trying to implement an analog of segmented control with two buttons. In default state they have no images, only labels, in selected one they have background image. I want to activate control with TouchDown event.
here is the code (I removed all unnecessary things):
-(IBAction) onButton1
{
button1.selected = YES;
button2.selected = NO;
}
-(IBAction) onButton2
{
button1.selected = NO;
button2.selected = YES;
}
the problem is: assume button1 is selected. When I touch button2 it does not change its image to "selected" image (there is no default image, as I've said), but when I release finger it changes. Also, if I touch already selected button it removes "selected" image and return it when I release it.
I've set highlighted state of buttons, so they have "selected" image in that state, but it did not help (not only in IB, but also with [button setBackgroundImage:[UIImage imageNamed:#"selected.png"] forState:UIControlStateHighlighted];). I've set adjustsImageWhenHighlighted = NO, that did not help too, again, in both program way and IB.
I've seen a lot of similar (but not identical) questions here, but they did not work for me.
Thanks in advance
Since, you wanted to activate the action at touch down event, I assume that you dont need highlighting. Try the following code
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
button1 = [UIButton buttonWithType:UIButtonTypeCustom];
button1.frame = CGRectMake(10.0f, 10.0f, 50.0f, 50.0f);
[button1 setBackgroundImage:[UIImage imageNamed:#"btn.jpeg"] forState:UIControlStateNormal];
[button1 setBackgroundImage:[UIImage imageNamed:#"btnsel.jpeg"] forState:UIControlStateSelected];
[button1 addTarget:self action:#selector(button1Action:) forControlEvents:UIControlEventTouchDown];
[button1 addTarget:self action:#selector(button1TouchUp:) forControlEvents:UIControlEventTouchUpInside|UIControlEventTouchUpOutside];
[self.view addSubview:button1];
button1.selected = YES;
button2 = [UIButton buttonWithType:UIButtonTypeCustom];
button2.frame = CGRectMake(80.0f, 10.0f, 50.0f, 50.0f);
[button2 setBackgroundImage:[UIImage imageNamed:#"btn.jpeg"] forState:UIControlStateNormal];
[button2 setBackgroundImage:[UIImage imageNamed:#"btnsel.jpeg"] forState:UIControlStateSelected];
[button2 addTarget:self action:#selector(button2Action:) forControlEvents:UIControlEventTouchDown];
[button2 addTarget:self action:#selector(button2TouchUp:) forControlEvents:UIControlEventTouchUpInside|UIControlEventTouchUpOutside];
[self.view addSubview:button2];
}
- (void)button1Action:(UIButton*)sender
{
button1.highlighted = NO;
button1.selected = YES;
button2.selected = NO;
}
- (void)button2Action:(UIButton*)sender
{
button2.highlighted = NO;
button2.selected = YES;
button1.selected = NO;
}
- (void)button1TouchUp:(id)sender
{
button1.highlighted = NO;
}
- (void)button2TouchUp:(id)sender
{
button2.highlighted = NO;
}
I've got a problem with the accessory views in the MKAnnotationViews, but it only occurs when using the iOS 3 SDK. The 3.1.3 version specifically.
I have a subclass of MKAnnotationView and I create instances of it the usual way:
SourceAnnotationView *annotationView = (SourceAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:kDefaultSourceAnnotationID];
if (annotationView == nil) {
#if DEBUG
NSLog(#"RecordViewController viewForAnnotation source %d",[sourceAnnotation.ioiIdent intValue]);
#endif
annotationView = [[[SourceAnnotationView alloc] initWithAnnotation:sourceAnnotation reuseIdentifier:kDefaultSourceAnnotationID] autorelease];
annotationView.delegate = self;
}
Later on in the code, I change the content of the callout bubble by doing:
UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeCustom];
[deleteButton setImage:[UIImage imageNamed:kDeleteAudioButtonImageName] forState:UIControlStateNormal];
deleteButton.frame = CGRectMake(0, 0, kAnnotationViewLeftAccessoryWidth, kAnnotationViewLeftAccessoryHeight);
deleteButton.tag = kDeleteAudioButtonTag;
deleteButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
deleteButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
[deleteButton addTarget:self action:#selector(calloutButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
selectedAnnotationView.leftCalloutAccessoryView = deleteButton;
UIButton *editAudioInfoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
editAudioInfoButton.frame = CGRectMake(0, 0, kAnnotationViewRightAccessoryWidth, kAnnotationViewRightAccessoryHeight);
editAudioInfoButton.tag = kEditInfoButtonTag;
editAudioInfoButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
editAudioInfoButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
[editAudioInfoButton addTarget:self action:#selector(calloutButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
selectedAnnotationView.rightCalloutAccessoryView = editAudioInfoButton;
with kAnnotationViewRightAccessoryWidth and kAnnotationViewRightAccessoryHeight being both equal to 32.
When I no longer need these buttons, I try (and in most cases manage) to get rid of them like this:
selectedAnnotationView.rightCalloutAccessoryView = nil;
selectedAnnotationView.leftCalloutAccessoryView = nil;
In iOS 4, this results in the accessory views dissapearing and everything working beautifully. However, in iOS 3 the two buttons stay, even though they're not clickable, as if they were not completely removed from the callout's view.
Also, if I click any other annotation view the two buttons appear.
Does anyone know how to solve this?
Thanks!
EDIT:
Here is a picture of what happens:
make call after
selectedAnnotationView.rightCalloutAccessoryView = nil;
selectedAnnotationView.leftCalloutAccessoryView = nil;
[selectedAnnotationView setNeedsDisplay];
I have been trying for a couple of days to find a way how to call action:selector on a custom button, derived from UIButton, which I want to associate with a pin annotation. The reason that I used a subclass is that I want to pass some data into this button object, in order to show another UIView displaying these data when the button is pressed.
The problem is that while executing, when I click on the pin annotation, it opens its button, and when I click on it, nothing happens. My showDetails: method is not called on receiving the touchupInside event as I set here:
[rightButton addTarget:self
action:#selector(showDetails:)
forControlEvents:UIControlEventTouchUpInside];
My question is how to inherit the methods of UIButton, like addTarget:action:forControlEvents:, buttonWithType:, etc., in order to use them in my subclass?
Here is the complete code concerning the problem:
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation
{
MKPinAnnotationView *annView=[[[MKPinAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:#"MyPin"] autorelease];
annView.animatesDrop=FALSE;
annView.canShowCallout = YES;
[annView setSelected:YES];
if ([[annotation title] isEqualToString:#"Current Location"]) {
annView.pinColor = MKPinAnnotationColorRed;
}
else {
annView.pinColor = MKPinAnnotationColorPurple;
}
annView.calloutOffset = CGPointMake(-5, 5);
PlaceMark *pm=(PlaceMark *)annotation;
AddressItem *ai=[pm getData];
//Another problem is that i cant set buttonWithType:UIButtonTypeDetailDisclosure cause it generate error cause it is a method of UIbutton superclass
MyDetailButton* rightButton = [MyDetailButton buttonWithType:UIButtonTypeCustom];
[rightButton setData:ai];
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
[rightButton addTarget:self action:#selector(showDetails:) forControlEvents:UIControlEventTouchUpInside];
annView.rightCalloutAccessoryView = rightButton;
return annView;
}
Thank you in advance. I hope that I have given a clear explanation of my problem.
I think you're on wrong way. To send action #selector your class need inherit from UIControl and not UIButton. Check out UIControl Class Reference I think the problem is here.
Do not hesitate to tell me if I did not understand your question.
I'm trying to use dynamic buttons created via code (no IB) in my project and they appear where and how I want them but they don't fire their actions.
UIButton *button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button1.frame = CGRectMake(475, 302, 49, 58);
[button1 setTitle:#"1"
forState:(UIControlState)UIControlStateNormal];
[button1 addTarget:self
action:#selector(goToFirstTrailer)
forControlEvents:(UIControlEvents)UIControlEventTouchDown];
[myImageView addSubview:button1];
-(void)goToFirstTrailer {
[self startAnimator:#"OutsideToTrailer1_" forNumFrames:60];
}
The imageView this is placed on has buttons and User Interaction Enabled On.
Any light you can shed would be much appreciated.
I think you have the wrong signature of the action method change that line to
-(void) goToFirstTrailer:(id)sender {
and where you set the action to
[button1 addTarget:self action:#selector(goToFirstTrailer:) forControlEvents:....
Important is the colon after the message name because I changed the action method signature to include the sender.
Edit I wrote a small sample project with just an imageView in the MainWindow.xib and created a button programmatically as follows
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
UIButton *button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button1.frame = CGRectMake(0.f, 0.f, 50.f, 50.f);
[button1 setTitle:#"1"
forState:(UIControlState)UIControlStateNormal];
[button1 addTarget:self
action:#selector(goToFirstTrailer:)
forControlEvents:(UIControlEvents)UIControlEventTouchDown];
imageView.userInteractionEnabled = YES; // <--- this has to be set to YES
[imageView addSubview:button1];
[self.window makeKeyAndVisible];
return YES;
}
It is quick and dirty and yes, I am misusing the application delegate as the view controller. I know it is bad.
Here is the action method
- (void) goToFirstTrailer:(id)sender {
imageView.backgroundColor = [UIColor redColor];
}
Setting the userInteractionEnabled property on the parent imageView makes the difference. With it set to NO which is the default, no events are routed to the button.
If myImageView is a UIImageView object, adding a subview to it (like UIButton) only displays the image that object is represented by. If you add that UIButton as a subview of a UIView, it should work perfectly. Try adding an auxiliary UIView to your UIImageView and then add your button to a subview of the new auxiliary UIView, that should solve your problem.
This works fine for me. Note that I changed the event to UIControlEventTouchUpInside to allow the button press down state to be visible first.
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(20,400,88,35); //The position and size of the button (x,y,width,height)
[btn setTitle:#"Quit" forState:UIControlStateNormal];
[btn addTarget:self
action:#selector(showAbout)
forControlEvents:(UIControlEvents)UIControlEventTouchUpInside];
[self.view addSubview:btn];
