Place the following methods in the UISearchBarDelegate proxy method or UISearchDisplayControllerdelegate proxy method:
1) If you want to change this character and replace it with the string you want, you can try:
for (UIView *subView in self.searchDisplayController.searchResultsTableView.subviews) { if ([subView isKindOfClass:NSClassFromString(@"UILabel")]) { UILabel *label =(UILabel *)subView; label.text = @"自定义字符串"; } }
2) If you simply want to cover this text, the best method I have ever used is:
for (UIView *subView in self.searchDisplayController.searchResultsTableView.subviews) { if ([subView isKindOfClass:NSClassFromString(@"UILabel")]) { UILabel *label =(UILabel *)subView; //自定义一个View CGFloat ViewWidth = [UIScreen mainScreen].bounds.size.width*0.64; CGFloat ViewHeight = ViewWidth*0.75; tempNoResultView = [[UIView alloc]init]; tempNoResultView.size = CGSizeMake(ViewWidth, ViewHeight); tempNoResultView.center = CGPointMake([UIScreen mainScreen].bounds.size.width/2, heightToTop); tempNoResultView.backgroundColor = [UIColor whiteColor]; [label addSubview:_tempNoResultView]; } } //相当于遍历出这个label,用一个View把“No Result”遮盖掉。只有这个方法虽然很low但是works well,用其他的方法并不稳定,因为并不建议修改这些东西而且UISearchDisplayController是个坑,这也是为什么后来苹果放弃UISearchDisplayController的原因。
It will appear when there is no data, just set a dummy cell.
When there is no data, set a blank cell. . Deal with it this way. .
