我有一个自定义scrollView,实现了以下方法:
- (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
//if not dragging send it on up the chain
if(!self.dragging){
[self.nextResponder touchesEnded:touches withEvent:event];
}else {
[super touchesEnded:touches withEvent:event];
}
}
在My View Controller中,我有以下方法:
-(void) touchesEnded: (NSSet *) touches withEvent: (UIEvent *) event {
NSLog(@"TOUCH");
//---get all touches on the screen---
NSSet *allTouches = [event allTouches];
//---compare the number of touches on the screen---
switch ([allTouches count])
{
//---single touch---
case 1: {
//---get info of the touch---
UITouch *touch = [[allTouches allObjects] objectAtIndex:0];
//---compare the touches---
switch ([touch tapCount])
{
//---single tap---
case 1: {
NSLog(@"Single");
[self mySingleTapMethod];
} break;
//---double tap---
case 2: {
[self myDoubleTapMethod];
} break;
}
} break;
}
}
在iOS 4下,这很有效,滚动视图的触摸得到识别,touchesEnded在我的视图控制器中被调用,所有这些都与世界一致。然而,在iOS 5x下,touchesEnded永远不会被解雇。有谁知道这是怎么回事?答案 0 :(得分:3)
在这里找到答案,基本上如果你想做我正在做的事情,你需要传递touchesBegan上链...因为如果一个viewController没有看到touchesBegan它将不会得到TouchesEnded ..所以我修改了自定义ScrollView以抛出touchesBegan,现在一切正常,5.0
