searchBar：shouldChangeTextInRange：replacementText不叫
问题描述：
searchBar：shouldChangeTextInRange：replacementText从未调用过。该代表被定义，方法 - searchBarShouldBeginEditing：和searchBarTextDidBeginEditing：工作正常，但shouldChangeTextInRange未被调用。我发现，当值存取在使用alertview后，我的方法尝试使用searchbar..the shouldChangeTextInRange叫...但在此之前没有searchBar：shouldChangeTextInRange：replacementText不叫
-(void) searchBarTextDidBeginEditing:(UISearchBar *)searchBar {
}
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
{
return YES;
}
-(BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
return YES;
}
-(BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar {
return YES;
}
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
}
答
我的appDelegate，已经错过下面的代码applicationDidFinishLauching
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window makeKeyAndVisible];
现在的搜索栏工作正常！
我做了一个测试，并把alertview视图中没有加载...钍searchBar工作...但我不想alertView：S – Ladessa
