NSInvalidArgumentException:发送给实例的无法识别的选择器
NSInvalidArgumentException:发送给实例的无法识别的选择器
提问于 2012-10-05 21:39:54
当我运行我的应用程序时，我得到这个错误：
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-
[UIRoundedRectButton copyWithZone:]: unrecognized selector sent to instance
0xcc86970'为什么会出现这样的错误？我小心翼翼地检查了IBOutlets e IBAction的所有连接。这是我的代码：
MenuViewController.h
@interface MenuViewController : UIViewController
<UITableViewDelegate, UITableViewDataSource>{
}
@property (nonatomic, copy) IBOutlet UITableView * tableView;
@property (nonatomic,copy) IBOutlet UILabel *labelTitle;
@property (nonatomic, copy) IBOutlet UIButton *buttonHome;
@property (nonatomic, copy) IBOutlet UIButton *buttonMap;
@property (nonatomic, copy) IBOutlet UIButton *buttonFavorites;
-(IBAction) pressedHome:(id)sender;
-(IBAction) pressedMap: (id)sender;
-(IBAction) pressedFavorites: (id)sender;
@end在MenuViewController.m中
-(IBAction) pressedHome:(id)sender{
MenuViewController * menu =[[MenuViewController alloc]initWithNibName:@"MenuViewController" bundle:nil];
[self.navigationController pushViewController:menu animated:YES];
}
-(IBAction) pressedMap: (id)sender{
MapViewController * map =[[MapViewController alloc]initWithNibName:@"MapViewController" bundle:nil];
[self.navigationController pushViewController:map animated:YES];
}
-(IBAction) pressedFavorites: (id)sender{
FavoritesViewController * favorites =[[FavoritesViewController alloc]initWithNibName:@"FavoritesViewController" bundle:nil];
[self.navigationController pushViewController:favorites animated:YES];
}提前感谢

卸下copy。这是因为UIButton (和其他UIControls)不符合NSCopying协议，所以复制它们的调用失败。

删除以下属性的copy
@property (nonatomic) IBOutlet UITableView * tableView;
@property (nonatomic) IBOutlet UILabel *labelTitle;
@property (nonatomic) IBOutlet UIButton *buttonHome;
@property (nonatomic) IBOutlet UIButton *buttonMap;
@property (nonatomic) IBOutlet UIButton *buttonFavorites;页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
