防止pinchgesture缩小原始帧

Question

是否可以阻止 UIPinchGestureRecognizer缩小原始帧？ 我知道这可以通过使用UIScrollView轻松完成，但在这种情况下这是不可能的。

我目前正在使用它来转换视图;

UIView *piece = gestureRecognizer.view;

CGPoint locationInView = [gestureRecognizer locationInView:piece];
CGPoint locationInSuperview = [gestureRecognizer locationInView:piece.superview];

[gestureRecognizer view].transform = CGAffineTransformScale([[gestureRecognizer view] transform], [gestureRecognizer scale], [gestureRecognizer scale]);
piece.layer.anchorPoint = CGPointMake(locationInView.x / piece.bounds.size.width, locationInView.y / piece.bounds.size.height);
piece.center = locationInSuperview;

Answer 1

缩小时缩放属性将小于1，放大时缩放大于1，因此只需在识别器触发时检查缩放，并且不要缩放视图以获得小于1的手势缩放。 / p>
