自定义Tableview 右滑自带的 Delete按钮

此方法在TableviewCell里写-(void)layoutSubviews{    [super layoutSubviews];         [self modifiDeleteBtn];}-(void)modifiDeleteBtn{    for (UIView *subView in self.subviews) {        if ([subView isKindOfClass:NSClassFromString(@"UITableViewCellDeleteConfirmationView")]) {            //subView.backgroundColor=[UIColor blueColor];            for (UIButton *btn in subView.subviews) {                if ([btn isKindOfClass:[UIButton class]]) {                    btn.backgroundColor=[UIColor colorWithRed:203.0/255 green:27.0/255 blue:69.0/255 alpha:1];                    [btn setTitle:@"删除" forState:UIControlStateNormal];                }            }        }    }}如果单纯的是修改文字 可以在controll里修改- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{    return @"删除";}
