Question

我得到了这个例外，我很清楚为什么会发生这种情况：

2013-08-10 06:23:21.417  Unknown class login in Interface Builder file.
2013-08-10 06:23:41.714 [HomeViewController revealMenu]: unrecognized selector sent to instance 0x7145bf0
2013-08-10 06:23:41.716 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[HomeViewController revealMenu]: unrecognized selector sent to instance 0x7145bf0'

libc++abi.dylib: terminate called throwing an exception

似乎通知我在HomeViewController中缺少revealMenu方法，但它就在那里

- (void)viewDidLoad
{
    ....
    [self.btnLeft addTarget:self action:@selector(revealMenu) forControlEvents:UIControlEventTouchUpInside];
    ....
}


-(IBAction)revealMenu:(id)sender
{
    [self.slidingViewController anchorTopViewTo:ECRight];
}

Answer 1

revealMenu和revealMenu:是两个不同的选择器，您正在调用一个不存在导致崩溃的选择器。用这个替换你的代码，它应该工作。（在选择器的末尾添加了冒号）

[self.btnLeft addTarget:self action:@selector(revealMenu:) forControlEvents:UIControlEventTouchUpInside];

冒号指定一个参数，所以......

-(IBAction)revealMenu

拥有revealMenu和

的选择器

-(IBAction)revealMenu:(id)sender

拥有revealMenu:和

的选择器

-(IBAction)revealMenu:(id)sender andSome:(NSObject *)otherArgument

选择器为revealMenu:andSome:

我无法翻译这个例外。怎么解决？
