したがって、非同期ライブラリhttps://github.com/caydenliew/AsyncSocketを使用しています。押されたときにサーバーに文字列を送信するボタンがあります。エラーはありませんが、次の例外が発生します。

これがkeyViewController.hです

@interface keyViewController ()
{
CFURLRef sysSoundTestPath;
GCDAsyncSocket *asyncSocket;

}
 -(IBAction) touchB:(id)sender;
 -(IBAction)touchE:(id)sender;
 -(void)loadViewFromNIB:(NSString *)nibName owner:(id)owner;
 - (void)sendData:(NSString *) dataSend ;
@end

そしてM

@implementation keyViewController

        asyncSocket = [(keyAppDelegate *)[[UIApplication sharedApplication] delegate] asyncSocket];

    }

    NSData *data = [dataSend dataUsingEncoding:NSUTF8StringEncoding];

    //write data to server

    [sender sendData:name];


}

- (IBAction)touchE:(id)sender

    NSLog(@"up");
    [sender transmitHandle];
}

    for (UIView *subview in subviews) {
        if ([subview isKindOfClass:[UIButton class]]) {
            UIButton *key = (UIButton *)subview;
            [key addTarget:self action:@selector(touchB:) forControlEvents:UIControlEventTouchDown];
            [key addTarget:self action:@selector(touchE:) forControlEvents:UIControlEventTouchUpInside];

            //NSString *ident = key.restorationIdentifier;
            //NSLog(@"%@",ident);
        }
    }
}

- (void)viewDidLoad

{
    [super viewDidLoad];
    [self.view setMultipleTouchEnabled:YES];
    [self loadViewFromNIB:@"keyViewController" owner:self];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
     //Dispose of any resources that can be recreated.
}

@end

私は何が間違っているのですか?

IBAction のセンダーは、押されたボタンです。sendData はコントローラーのメソッドです。押されたボタンに sendData を送信しています。送信者を自分自身に変更します。データ送信メソッドに送信しようとしている文字列はわかりませんが、ボタンに RestorationIdentifier というプロパティがあるかどうかはわかりません。

- (IBAction)touchB:(id)sender
{

    NSLog(@"down");
    NSString *path = [[NSBundle bundleWithIdentifier:@"com.apple.UIKit"] pathForResource:@"Tock" ofType:@"aiff"];
    NSURL* url = [NSURL fileURLWithPath:path];
    SystemSoundID soundID;
    AudioServicesCreateSystemSoundID( (CFURLRef)objc_unretainedPointer(url), &soundID);
    AudioServicesPlaySystemSound(soundID);
    [sender transmitHandle];
     NSString *name =  [sender restorationIdentifier];
    //I'm not sure what string you're trying to send to the send data method.
    NSLog(@"Sending:%@ to sendData method", name);
    [self sendData:name];
