tvOS如何識別Objective C的遠程手勢？

Question

我會如何去識別Objective-C的tvOS的遠程滑動和按鈕敲擊？到處都是我發現的Swift，我還不習慣。

謝謝！

從你的榜樣雨燕代碼：

let swipeDown:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector("swipedDown:")) 
swipeDown.direction = .Down 
view.addGestureRecognizer(swipeDown) 

func swipedDown(sender:UISwipeGestureRecognizer){ 
    NSLog("It worked") 
} 

翻譯成目標C：

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeDown:)]; 
    recognizer.direction = UISwipeGestureRecognizerDirectionDown; 
    [self.view addGestureRecognizer:recognizer]; 
} 

- (void)swipeDown:(UISwipeGestureRecognizer *)sender 
{ 
    NSLog(@"It works"); 
} 

這似乎工作：

例如的SWIFT代碼。

let tapRecognizer = UITapGestureRecognizer(target: self, action: "tapped") 
tapRecognizer.allowedPressTypes = [NSNumber(integer: UIPressType.Select.rawValue)]; 
self.tabBar.addGestureRecognizer(tapRecognizer) 

let swipeRecognizerRight = UISwipeGestureRecognizer(target: self, action: "swipedRight") 
swipeRecognizerRight.direction = .Right //.Left,.Up,.Down. 
self.tabBar.addGestureRecognizer(swipeRecognizer) 

而且這些方法：

func tapped(){ 

    // write her your code. 

} 

func swipeRecognizer(){ 

    // write her your code. 

}
