让UISearchBar搜索框彻底透明

如果你用各种方法都无法令UISearchBar透明，以下方法可以试试

[[searchbar.subviews objectAtIndex:0]removeFromSuperview];  直接将立体效果的视图移出，这样就只剩下搜索框框了。

怎么改变uisearchbar中的cancel按钮的文字

 

- (void)searchBarTextDidBeginEditing:(UISearchBar *)hsearchBar

{
    searchBar.showsCancelButton = YES;
    for(id cc in [searchBar subviews])
    {
        if([cc isKindOfClass:[UIButton class]])
        {
            UIButton *btn = (UIButton *)cc;
            [btn setTitle:@"取消"  forState:UIControlStateNormal];
        }
    }
}

更改UISearchDisplayController无结果显示"No Results"

 dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, 0.001);

    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){

        for (UIView* subview in telSearchDisplayController.searchResultsTableView.subviews) {

            if ([subview isKindOfClass: [UILabel class]] &&

                [[(UILabel*)subview text] isEqualToString:@"No Results"]) {

                 

                UILabel *lbl = (UILabel*)subview; // sv changed to subview.

                lbl.text = @"没有结果";

                break;

            }

        }

    });
