圖像在圖像視圖中旋轉360度在iOS中的3D度

Question

我正在開發一個應用程序，其中我想UIImage應該在UIImageView 360度，3維中旋轉。 我已經嘗試了許多代碼，但CAAnimation的所有代碼順時針旋轉整個圖像或翻轉整個圖像視圖。 那麼，我該如何開發這種類型的功能呢？

在斯威夫特，你可以使用無限旋轉下面的代碼： 斯威夫特 -

let kRotationAnimationKey = "com.myapplication.rotationanimationkey" // Any key 

func rotateView(view: UIView, duration: Double = 1) { 
    if view.layer.animationForKey(kRotationAnimationKey) == nil { 
     let rotationAnimation = CABasicAnimation(keyPath: "transform.rotation") 

     rotationAnimation.fromValue = 0.0 
     rotationAnimation.toValue = Float(M_PI * 2.0) 
     rotationAnimation.duration = duration 
     rotationAnimation.repeatCount = Float.infinity 

     view.layer.addAnimation(rotationAnimation, forKey: kRotationAnimationKey) 
    } 
} 

停車是這樣的：

func stopRotatingView(view: UIView) { 
    if view.layer.animationForKey(kRotationAnimationKey) != nil { 
     view.layer.removeAnimationForKey(kRotationAnimationKey) 
    } 
}

這個工作完全適合我：iphone UIImageView旋轉

#import <QuartzCore/QuartzCore.h> 

    - (void) runSpinAnimationOnView:(UIView*)view duration:(CGFloat)duration rotations:(CGFloat)rotations repeat:(float)repeat; 
    { 
     CABasicAnimation* rotationAnimation; 
     rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"]; 
     rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 /* full rotation*/ * rotations * duration ]; 
     rotationAnimation.duration = duration; 
     rotationAnimation.cumulative = YES; 
     rotationAnimation.repeatCount = repeat; 

     [view.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"]; 
    }
