Animate düğmesi 360 saat yönünde ve geri geri

Question

Saat yönünde 360 ​​derece bir düğme oluşturun ve ardından animasyonu 360 saatin tersi yönde tersine çevirin. Fakat animasyon ... Animasyon her zaman 360 saat yönünde.

func animateShowingOfMenu(){ 

     let angle = CGFloat(180 * M_PI/180) 
     UIView.animateWithDuration(0.4 
      , animations: {() -> Void in 

       self.blurView.hidden=false 
       self.menuBtn.transform = CGAffineTransformMakeRotation(angle) 
       self.menuBtn.transform = CGAffineTransformMakeRotation(0) 


      }) { (completion) -> Void in 

       print("compeleted") 
     } 

    } 

    func animateHidingOfMenu(){ 

     let angle = CGFloat(-180 * M_PI/180) 
     UIView.animateWithDuration(0.4 
      , animations: {() -> Void in 

       self.blurView.hidden = true 
       self.menuBtn.transform = CGAffineTransformMakeRotation(angle) 
       self.menuBtn.transform = CGAffineTransformMakeRotation(0) 


      }) { (completion) -> Void in 

     } 
    } 

Answer 1

Basit ortak çözüm Sen Diyelim ki (burada self.imageV olarak adlandırılır) bir imageView döndürmek istediğinizi varsayalım için herşeyi

//Clock-wise 
rotateAnyView(makeOrderButton, fromValue: 0, toValue: 2.0 * M_PI, duration: 1) 

//Reverse 
rotateAnyView(makeOrderButton, fromValue: 2.0 * M_PI, toValue:0, duration: 1) 

func rotateAnyView(view: UIView, fromValue: Double, toValue: Float, duration: Double = 1) { 
    let animation = CABasicAnimation(keyPath: "transform.rotation") 
    animation.duration = duration 
    animation.fromValue = formValue 
    animation.toValue = toValue 
    view.layer.addAnimation(animation, forKey: nil) 
} 

Answer 2

Objective-C

PFB cevap:

CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"]; 
animation.duration = 1; 
animation.fromValue = [NSNumber numberWithFloat:0]; 
animation.toValue = [NSNumber numberWithFloat:2 * M_PI]; 
animation.autoreverses = YES ; 
[self.containerView.layer addAnimation:animation forKey:nil]; 

tadını çıkarın! rotasyon kısa yönde

Answer 3

self.menuBtn.transform = CGAffineTransformMakeRotation(CGFloat(-90 * M_PI/180)) 
self.menuBtn.transform = CGAffineTransformMakeRotation(CGFloat(M_PI) 
self.menuBtn.transform = CGAffineTransformMakeRotation(CGFloat(90 * M_PI/180)) 
self.menuBtn.transform = CGAffineTransformMakeRotation(CGFloat(0) 

bu benim varsayımdır. 180 her iki yönden de aynı olduğu için, her zaman saat yönünde döner. Bu yüzden saat yönünün tersine 90 derece kullanarak bir yön veriyoruz. Swift

UIView.animateKeyframesWithDuration(1.0, delay: 0, options: [.Repeat], animations: { 
      UIView.addKeyframeWithRelativeStartTime(0, relativeDuration: 0.25, animations: { 
       self.imageV.transform = CGAffineTransformMakeRotation(90.0 * CGFloat(M_PI)/180.0) 
      }) 
      UIView.addKeyframeWithRelativeStartTime(0.25, relativeDuration: 0.25, animations: { 
       self.imageV.transform = CGAffineTransformMakeRotation(180.0 * CGFloat(M_PI)/180.0) 
      }) 
      UIView.addKeyframeWithRelativeStartTime(0.50, relativeDuration: 0.25, animations: { 
       self.imageV.transform = CGAffineTransformMakeRotation(270.0 * CGFloat(M_PI)/180.0) 
      }) 
      UIView.addKeyframeWithRelativeStartTime(0.75, relativeDuration: 0.25, animations: { 
       self.imageV.transform = CGAffineTransformMakeRotation(360.0 * CGFloat(M_PI)/180.0) 
      }) 

      }, completion: nil)
