在UILongPressGestureRecognizer中获取每次触摸的坐标

Question

我有一个UILongPressGestureRecognizer设置numberOfTouchesReguired = 2.如何在视图上获得每个手指的连续坐标？

目前我有这个,但它似乎将所有触摸的位置组合成1个坐标.

- (void)handleLongPress:(UILongPressGestureRecognizer *)sender {
    CGPoint locationInView = [sender locationInView:nil];
}

Answer 1

请参阅文档UIGestureRecognizer.它提供了以下方法:

- (void)handleLongPress:(UILongPressGestureRecognizer *)sender {
    if (sender.state == UIGestureRecognizerStateChanged) {
        NSUInteger *touchCount = [sender numberOfTouches];
        for (NSUInteger t = 0; t < touchCount; t++) {
            CGPoint point = [sender locationOfTouch:t inView:sender.view];
        }
    }
