问题描述
如何循环浏览UIView及其子视图及其子视图的所有子视图?
How can I loop through all subviews of a UIView, and their subviews and their subviews?
推荐答案
使用递归:
// UIView+HierarchyLogging.h
@interface UIView (ViewHierarchyLogging)
- (void)logViewHierarchy;
@end
// UIView+HierarchyLogging.m
@implementation UIView (ViewHierarchyLogging)
- (void)logViewHierarchy
{
NSLog(@"%@", self);
for (UIView *subview in self.subviews)
{
[subview logViewHierarchy];
}
}
@end
// In your implementation
[myView logViewHierarchy];
