objective-c - ios push页面后部分控件不会跟着push,大神们知道吗?

Question

就好像iPhone的 Safari浏览器 里面的bookmarks按钮,点进去后,点击tableViewcell,segment不会跟着push,求一些思路!][2]

迷茫 · Answer

This is because it puts the Segment into the NavigationBar

黄舟 · Answer

The view is placed on the keywindow

怪我咯 · Answer

The problem has been solved. Thank you for the advice upstairs. It is indeed possible to use keyWindow to prevent push from happening

UISegmentedControl * segment = [[UISegmentedControl alloc]initWithItems:@[@"♞",@"♟",@"♚"]];
segment.frame = CGRectMake(10, 60, SCREEN_WIDTH-20, 30);
[[UIApplication sharedApplication].keyWindow addSubview:segment];

I found out later that it can also be achieved by placing it on the NavigationBar
Add subviews in the custom UIViewController

[self addChildViewController:self.bookmarkVC];
