UICalloutView is a "callout" view which looks like a dialog box. It was used in MobileMaps.app.
Using UICalloutView
UICalloutView* callout = [UICalloutView sharedCalloutView];
[callout setTitle:@"Title"];
[callout setSubtitle:@"subtitle"];
[callout addTarget:self action:@selector(closeCalloutView:)];
[window addSubview:callout];
[callout setAnchorPoint:CGPointMake(80, 40) boundaryRect:[UIScreen mainScreen].applicationFrame animate:YES];
...
-(void)closeCalloutView:(UIButton*)sender {
[(UICalloutView*)sender.superview fadeOutWithDuration:1];
}
UICalloutView delegate
Signature | @property(assign,nonatomic) id delegate; |
---|---|
Available in | 2.0 — 3.1 |
One could assign a delegate to a UICalloutView. The delegate must conform to the informal protocol:
@protocol UICalloutViewDelegate
@optional
-(void)calloutView:(UICalloutView*)calloutView willMoveToAnchorPoint:(CGPoint)newPoint animated:(BOOL)animated;
-(void)calloutView:(UICalloutView*)calloutView didMoveToAnchorPoint:(CGPoint)newPoint animated:(BOOL)animated;
@end
