问题描述

我想列出 UIViewController 中的所有子视图.我试过self.view.subviews，但是并不是所有的子视图都列出来了，比如没有找到UITableViewCell中的子视图.有什么想法吗?

I want to list out all the subviews in a UIViewController. I tried self.view.subviews, but not all of the subviews are listed out, for instance, the subviews in the UITableViewCell are not found. Any idea?

推荐答案

你必须递归迭代子视图.

You have to recursively iterate the sub views.

- (void)listSubviewsOfView:(UIView *)view {
    
    // Get the subviews of the view
    NSArray *subviews = [view subviews];

    for (UIView *subview in subviews) {
        
        // Do what you want to do with the subview
        NSLog(@"%@", subview);

        // List the subviews of subview
        [self listSubviewsOfView:subview];
    }
}
