objective-c - 单击子视图时将值设置为超级视图

Question

我已经动态创建了具有许多按钮的 uiviews。它用于从每一行（uiview）中选择特定值（uibutton）。单击按钮时，我必须更改按钮图像（如突出显示）。现在我越来越喜欢那个，但是顺序不匹配。在某些行中没有选择按钮。请检查下面的代码

for (int j=0; j<[viewTagAry count]; j++)
    {  
        if ([[viewTagAry objectAtIndex:j] isEqualToString:[NSString stringWithFormat:@"%d",v]]) 
        {  
            for (int i=0; i<[lastSelectedButtonAry count]; i++) 
            {
                lastSelectedButton=[lastSelectedButtonAry objectAtIndex:i];
                int tag=[[btnTagArray objectAtIndex:i] intValue];
                UIImage *numImg=[UIImage imageNamed:[NSString stringWithFormat:@"%db.png",tag]];
                [lastSelectedButton setBackgroundImage:numImg forState:UIControlStateNormal];
            }
}
}
-(void)highlightButton:(id)sender{

    UIButton *button = (UIButton *)[sender userInfo];
    int t=button.tag+1;

            UIImage *numImg=[UIImage imageNamed:[NSString stringWithFormat:@"%da.png",t]];
            [button setBackgroundImage:numImg forState:UIControlStateNormal];
