ios - 在 UIImageView 中滑动大图像

Question

我有一张宽度为 1000 像素的大图片。我想以原始大小显示图像，并希望它在动画中自动从右向左滚动。例如在iPhone 6中应该先显示375px，然后向左移动，直到照片的所有部分都及时显示出来。我该怎么做？

Answer 1

// You have to put the imageView inside a UIScrollView
// Set the duration you want for your animation
[UIView animateWithDuration:1.5f animations:^{
    //Code for animation
    [scrollView setContentOffset:CGPointMake(imageView.frame.size.width - scrollView.frame.size.width, scrollView.contentOffset.y) animated:NO];
} completion:^(BOOL finished) {
    //Code after the animation is completed
}];
