Question

我在主视图中以编程方式添加了视图。在父视图中，我将以编程方式将imageview添加为子视图。现在我已经为clickview设置了触摸事件，但它不起作用。它没有在点击时检测到触摸事件。我正在使用以下代码触摸事件的imageview。

- （void）touchesBegan：（NSSet *）触及withEvent：（UIEvent *）event {

UITouch *touch = [touches anyObject];

if ([touch view] == originalphoto)
{
    [fullview setHidden:NO];
    [self.view addSubview:fullview];
    [setimage setImage:image];
}

}

有没有人知道如何设置以编程方式添加的imageview的触摸事件？

非常感谢。

Answer 1

为什么不使用手势？这很容易。您可以使用UITapGestureRecognizer让它适合您：http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UITapGestureRecognizer_Class/Reference/Reference.html

Answer 2

UITouch *touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView:UIIMAGEVIEW];// uiimageview object
touchx = location.x;
touchy = location.y;
NSLog(@" x= %i ", touchx);
NSLog(@"y = %i",touchy);

Answer 3

//为您的视图添加手势

UITapGestureRecognizer *Tap= [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(ResignResponder:)];
[tempV addGestureRecognizer:Tap];

[Tap release];

//method will be called on tapping the view
-(void)ResignResponder:(UIGestureRecognizer*)recognizer {
        [LocSearchField resignFirstResponder];
        [self.view sendSubviewToBack:tempV];
 }

也许你需要设置属性imageView.userInteractionEnabled = YES？

uimageview上的触摸事件作为父视图的子视图添加
