將uimageview的觸摸事件添加爲父視圖的子視圖

Question

我已經在主視圖中以編程方式添加了視圖。在父視圖中，我將程序添加爲子視圖。現在我已經爲clickview設置了touchview的觸摸事件，但它不起作用。點擊時沒有檢測到觸摸事件。我正在使用下面的imageview觸摸事件代碼。

- （空）的touchesBegan：（NSSet中*）觸及withEvent：方法（的UIEvent *）事件{

UITouch *touch = [touches anyObject]; 

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

}

做任何人有想法，如何設置ImageView的觸摸事件，這已以編程方式添加？

非常感謝。

Answer 1

//添加手勢你的觀點

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]; 
} 

Answer 2

爲什麼不使用手勢？它很容易。你可以使用UITapGestureRecognizer並讓它爲你工作：http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UITapGestureRecognizer_Class/Reference/Reference.html

Answer 3

也許你需要設置屬性imageView.userInteractionEnabled = YES？

Answer 4

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);
