检测手指，UIButton和UIImageView是否重叠

Question

我使用此代码来检测UIButton和UIImageView何时重叠：

CGPoint fingerPoint = [(UIPanGestureRecognizer*)sender locationInView:imageA.superview];
    if (CGRectContainsPoint(imageA.frame, fingerPoint)) {
        NSLog(@"Do something");
    }

代码工作正常，但我有图像B，C，D，E。 如何循环它们的集合并将CGRectContainsPoint()移动到该循环的主体中？

Answer 1

NSArray* images = @[ imageA, imageB, imageC, imageD, imageE ];
for (UIImageView* image in images) {
    CGPoint fingerPoint = [(UIPanGestureRecognizer*)sender locationInView:[image superview]];
    if (CGRectContainsPoint(image.frame, fingerPoint)) {
        // Do something.
    }
}
