私はここと同じ問題を抱えているようです:ジェイルブレイクされたiOSでNSTask waitUntilExitがアプリをハングアップ

NSNotification (上記のように) を介して取得したものを次に示しますが、taskEnded:アラートは表示されません。デバッガーで確認できるように、スクリプトは確実に実行されます。

-(IBAction) supported {
    stask = [[NSTask alloc] init];
    [stask setLaunchPath:@"/bin/bash"];
    NSString *script;
    script = [[[NSBundle mainBundle] bundlePath] stringByAppendingString:@"/apps.sh"];
    NSArray *sargs = [NSArray arrayWithObjects:script, @"-txt", nil];
    [stask setArguments: sargs];
    [[NSNotificationCenter defaultCenter] addObserver: self
                                             selector: @selector(taskEnded:)
                                                 name: NSTaskDidTerminateNotification
                                               object: nil]; 
    [stask launch];
}

- (void)taskEnded:(NSNotification *)notification {
    if (stask == [[notification object] terminationStatus]) {
        NSString *apps;
        apps = [NSString stringWithContentsOfFile:@"/var/mobile/supported.txt" encoding:NSUTF8StringEncoding error:nil];
        NSFileManager *fm = [NSFileManager defaultManager];
        if ([fm fileExistsAtPath:apps]) {
            UIAlertView *supported = [[UIAlertView alloc] initWithTitle:@"Apps" message:apps delegate:self cancelButtonTitle:@"Ok!" otherButtonTitles:nil];
            [supported show];
            [supported release];
        } else {
            UIAlertView *supported = [[UIAlertView alloc] initWithTitle:@"Apps" message:@"Error generating list." delegate:self cancelButtonTitle:@"Ok!" otherButtonTitles:nil];
            [supported show];
            [supported release];
        }
    } else {
        NSLog(@"Task failed."); 
    }
}
