UISearchDisplayController 去除“No Results”，“无结果” 的显示方法

UISearchDisplayController 去除“No Results” 的显示方法
实现此delegate方法就可以了，如果是中文添加一个判断[[(UILabel*)v text] isEqualToString:@"无结果"] 就ok了
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller
shouldReloadTableForSearchString:(NSString *)searchString {
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, 0.001);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
for (UIView* v in self.sbc.searchResultsTableView.subviews) {
if ([v isKindOfClass: [UILabel class]] &&
[[(UILabel*)v text] isEqualToString:@"No Results"]) {
// .. do whatever you like to the UILabel here ..
break;
}
}
});
return YES;
}
