searchDisplayControllerWillEndSearch 不调整搜索栏大小

Question

只是想知道为什么并且需要解决它。我的搜索栏看起来像这样。 单击的

将移动到顶部并扩展到 0,0,320,搜索栏的高度。

单击“取消”，它应该调整回搜索栏的高度 33,55,270。但它不会

searchDisplayControllerDidEndSearch 将调整大小，但是用户会出现 1 秒的延迟可以看到变化。为什么在 searchDisplayControllerWillEndSearch 中动画调整伤口大小不起作用？

感谢您的评论和反馈。

当我开始使用 UISearchBar 和 UISearchDisplayController 后，我遇到了同样的问题。我想出的解决方案是将搜索栏放在视图上：

UIView * searchBarSubview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, MENU_WORK_AREA_WIDTH, SEARCH_BAR_HEIGHT)] ;
searchBarSubview.autoresizesSubviews = YES;
searchBarSubview.backgroundColor = [UIColor clearColor];

UISearchBar * globalSearchBar = [[[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, MENU_WORK_AREA_WIDTH, SEARCH_BAR_HEIGHT)] autorelease];
globalSearchBar.tintColor = [UIColor blackColor];
globalSearchBar.delegate = self;
[globalSearchBar setBackgroundImage:[UIImage alloc]];

并调整视图的大小，而不是在 searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller 中调整搜索栏：

[UIView beginAnimations:nil context:nil];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.3];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];

// Slide in to the final destination
searchBarSubview.frame = CGRectMake(0, 0, MENU_WORK_AREA_WIDTH, SEARCH_BAR_HEIGHT);

[UIView commitAnimations];
