尝试将你的代码段更好。这是不是真的可读.. –

你试图改变每一行的'cellButton'UIButton的图像，当一个按钮在其他地方被按下，然后再次按下该按钮时删除或改回它？ – mattacular

在

- (void)StartTimer:(id)sender;

做

UIButton* button = (UIButton*)sender; 
UITableViewCell *cell = (UITableViewCell*)[[button superview] superview]; 
NSIndexPath indexPath = [self.tableview indexPathForCell:cell]; 
if([button imageForState:UIControlStateNormal] == [appDelegate.imageArray objectAtIndex:indexPath.row]) { 
    [button setImage:[UIImage imageNamed:@"NEWIMAGE.png"] forState:UIControlStateNormal]; 
} 
else { 
    [button setImage:[appDelegate.imageArray objectAtIndex:indexPath.row] forState:UIControlStateNormal]; 

}

没有测试，包括错别字，但应该工作。

MFG，
