我收到了以下错误,非常新的iphone开发和目标C.我非常愿意发送我的项目让某人看看,我在圈子里跑,不知道接下来该做什么!

我的目标是UITableViewCell在屏幕的一侧(例如在Twitter中)滑动,然后从另一侧滑回.我能够让细胞从屏幕向右滑动,但我似乎无法弄清楚如何让它从左后方滑回到屏幕上.这是我的代码,将其向右滑动:

UITableViewCell *cell = [self cellForRowAtIndexPath:indexPath];
[cell.layer setAnchorPoint:CGPointMake(0, 0.5)];
[cell.layer setPosition:CGPointMake(cell.frame.size.width, cell.layer.position.y)];
CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position.x"];
[animation setRemovedOnCompletion:NO];
[animation setDelegate:self];
[animation setDuration:0.14];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]];
[cell.layer addAnimation:animation forKey:@"reveal"];

谢谢你的帮助!
