iphone - 捏合识别后捏合结束或润色？

Question

我只是在寻找一个我可以捕捉到的合适的事件。捏效果很好。并且以下行仅在之前没有夹点时才有效

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent*)event 
{
    NSLog(@"---> event");
}

似乎捏吃掉了下面的润色。

无论如何，在这段代码中，修饰被识别了

- (void)scalePiece:(UIPinchGestureRecognizer *)gestureRecognizer
{
    //[self adjustAnchorPointForGestureRecognizer:gestureRecognizer];

    NSLog(@"scalePiece");

    if ([gestureRecognizer state] == UIGestureRecognizerStateBegan || [gestureRecognizer state] == UIGestureRecognizerStateChanged) {
        [gestureRecognizer view].transform = CGAffineTransformScale([[gestureRecognizer view] transform], [gestureRecognizer scale], [gestureRecognizer scale]);
        [gestureRecognizer setScale:1];
    }
}

如何在捏合 View 后识别最后/第二根手指的触摸？或者更好地说，我如何区分捏合移动和捏合结束？

干杯

Answer 1

您可以使用:

if ([gestureRecognizer state] == UIGestureRecognizerStateEnded)

在你的捏函数中
