之前设置UITableViewCell的checkMark的属性，有20个cell

选择其中的一个进行设置checkmark ,但是一直无法设置成功，之前采用的方式是通过indexPath来标记

将上一个indexPath设置为oldIndexPath, 但是无法标记成功，后面把上一个 UITableViewCell 来作为标记，可以解决。

代码如下

 

[tableView deselectRowAtIndexPath:indexPath animated:YES];    if ([indexPath section] == 0) {        if (self.wallpaperIndexpath != nil) {            wallpaperOldCell.accessoryType = UITableViewCellAccessoryNone;        }        [[tableView cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryCheckmark];        wallpaperOldCell = [tableView cellForRowAtIndexPath:indexPath];        self.wallpaperIndexpath = indexPath;        NSLog(@"Wallpaper new index path is %@", indexPath);    }else if ([indexPath section] == 1){        if (self.ringtoneIndexpath != nil) {            ringtoneOldCell.accessoryType = UITableViewCellAccessoryNone;        }        [[tableView cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryCheckmark];        ringtoneOldCell = [tableView cellForRowAtIndexPath:indexPath];        self.ringtoneIndexpath = indexPath;        NSLog(@"Ringtone new index path is %@", indexPath);    }
