iphone - 如何捏放大图片库

Question

我想要多张照片，比如标准画廊

我想捏放大所有照片。我可能对每张图片都有一个 UIImageView （我是对的），所以当我捏入画廊视图时，我想缩放所有画廊。这可能吗？如何？

Answer 1

Try this: put all your photos in one view, that would be subview of your scrollview. Then, in your scrollview delegate implement method

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

In which just return view that contains all photos. Do not forget to set appropriate scrollview content size and maximum and minimum zoom scale.

Answer 2

put the pictures in a scollview. set the property scrollview.scalePagesToFit; . set the scrollView delegate.
