ios cell 重用问题－－图片remove

因为一个UITableView  会reload 多次，所以在cell中添加 UI控件时，也会重复加载多次，以至于叠加在上面，

解决办法： 每次用到它时，对其进行初始化做判断，为空则初始化，否则 就不init

UIImageView *_rightImageView = (UIImageView*)[cell viewWithTag:1007];

if ((UIImageView*)[cell viewWithTag:1007] == nil)
{
_rightImageView = [[UIImageView alloc]initWithFrame:CGRectMake(DEVICEWIDTH - 55, 8, cellImageWidth, cellIimagehight)];
_rightImageView.tag = 1007;
}

if (_License )
{
if (_rightImageView != nil)
{
[(UIImageView*)[cell viewWithTag:1007] removeFromSuperview];
}

// UILabel *_tempLabel = [self generateNameLabel:_status];
_tempLabel.text = _status;
[cell addSubview:_tempLabel];
}
