在uiscroll视图中缩放时,如何使图像不调整大小?

您可以将图钉图像作为uiscrollView的子视图,而不是由返回的视图子视图

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView

然后,在滚动视图中,通过缩放比例调整图钉X和Y,以使图钉正确定位:

- (void)scrollViewDidZoom:(UIScrollView *)scrollView {
    imageView.frame = CGRectMake(pushPinX * scrollView.zoomScale, pushPinY * scrollView.zoomScale, imageView.frame.size.width, imageView.frame.size.height);
}
