获取tableviewcell上控件的位置

今天在做项目的时候需要获取cell上一个button在屏幕的位置

#pragma mark - 弹出视图
-(void)popMarketAreasInLianMengVC:(UIButton *)sender{
    
    NSIndexPath *indexPath = [joinTable indexPathForCell:(JoinTableCell *)sender.superview.superview];
    
    CGRect rectInTableView = [joinTable rectForRowAtIndexPath:indexPath];
    
    
    CGRect rect = [joinTable convertRect:rectInTableView toView:[joinTable superview]];
    
    
    NSLog(@"sender = %f", rect.origin.y);
    
    PopAlertView *popView = [[PopAlertView alloc] initWithFrame:self.view.bounds];
    [popView creatUIWithType:3 withPoint:rect.origin.y];
    popView.isNeed = NO;
    [popView pop];
    
}
