我在自定义单元格按钮上使用addTarget,如:
[cell.btnGet addTarget:self action:@selector(getLocal:cell:) forControlEvents:UIControlEventTouchUpInside];
应该调用这个方法:
-(void)getLocal:(id)sender withcell:(GroupListCell *)cell
{
// code for implement
}
但是当我点击按钮时,它会抛出错误:
2013-02-27 14:28:56.533 iOSPlayer[704:11303] -[GroupView getLocal:cell:]: unrecognized selector sent to instance 0x72e1290
2013-02-27 14:28:56.534 iOSPlayer[704:11303] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[GroupView getLocal:cell:]: unrecognized selector sent to instance 0x72e1290'
这里有什么问题?

试试这个:
[cell.btnGet addTarget:self action:@selector(getLocal:withcell:) forControlEvents:UIControlEventTouchUpInside];

该行动方法被称为:
getLocal:withcell:
而不是:
getLocal:cell:
它也不匹配任何可接受的操作方法签名,它们是:
- (IBAction)doSomething;
- (IBAction)doSomething:(id)sender;
- (IBAction)action:(id)sender forEvent:(UIEvent *)event;
