iPhone:如何从UIScrollView中删除所有对象

Question

基本上我想从UIScrollView中删除所有对象,我还没有找到解决方案,因为简单的"removeAllObjects"命令不起作用.有谁知道怎么做？

Answer 1

更简单:

[[scrollView subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];

Answer 2

最简单的方法:

for(UIView *subview in [scrollView subviews]) {

    [subview removeFromSuperview];

}
