[問題]gesture recognizer while UIView animate
請問有辦法在 UIView animateWithDuration的時候觸發
gesture recognizer 的event嗎?
舉例來說: 我有一個 UIImageView 使用UIView animate的方法從螢幕左邊移動到右邊
但是我希望在移動中的同時可以接收到gesture recognizer的event
下面是我實驗失敗的code，每次都要等球移動完後才有辦法觸發recognizer的event。
想請問有沒有其他方法讓球在移動的同時又可以被drag呢？
謝謝。
Code example:
-(void)addBall{
UIImageView *ball = [[UIImageView alloc]initWithFrame:CGRectMake(0,50,50,50)];
[self addLongPressRecognizer:ball];
[UIView animateWithDuration:10
delay:0
options:UIViewAnimationOptionAllowUserInteraction
animations:^{
[ball setFrame:CGRectMake(1024,50,50,50)];
}
completion:nil];
}
- (void)addLongPressRecognizer:(UIView *)target
{
UILongPressGestureRecognizer *longPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];
longPressGestureRecognizer.delegate = self;
longPressGestureRecognizer.minimumPressDuration = .001;
[target addGestureRecognizer:longPressGestureRecognizer];
target.userInteractionEnabled = YES;
}
- (void)handleLongPress:(UIPanGestureRecognizer *)gestureRecognizer
{
UIView *ball = gestureRecognizer.view;
[ball.layer removeAllAnimations];
CGPoint point = [gestureRecognizer locationInView:self.view];
if (gestureRecognizer.state == UIGestureRecognizerStateChanged) {
ball.center = point;
}
}
