UIView 進行各種動畫展示及其用法解釋

//第一種動畫方式

- (void) first_animations

{
    [UIView beginAnimations:nil context:nil];  //啟動動畫動作
    [UIView setAnimationRepeatCount:1];//設置是否重復播放
    [UIView setAnimationDuration:1];//設置動畫持續時間
    [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; //動畫曲線,具體的應用 ,可以經過實驗檢測
    [UIView setAnimationDelegate:self];//動畫塊的某個方法(最下方),委托到本類的實例
    [UIView setAnimationDidStopSelector:@selector(resetView)];//動畫結束后去執行的方法
    
    CGAffineTransform oneTransform = CGAffineTransformRotate(self.animatView.transform, degreesToRadian(180));//進行  CGAffineTransform 方式的動作(旋轉拉伸等等)===>(對於CGAffineTransform  可以另外開辟一個關於CGAffineTransform使用詳情的文章進行專門介紹 )

 

    CGAffineTransform twoTransform = CGAffineTransformTranslate(self.animatView.transform,0,-100);
    CGAffineTransform newTransform = CGAffineTransformConcat(oneTransform, twoTransform);
    [self.animatView setTransform:newTransform];
    [UIView commitAnimations];//有些網友說,這是動畫結束.起始經過本人嘗試試驗.其實應該是,執行上方定義的動畫塊內容.
}

//第二中動畫定義方式
- (void) second_animations
{
    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"opacity"];
    [animation setDuration:1];
    [animation setRepeatCount:0];
    [animation setAutoreverses:YES];//自動反向動畫
    [animation setFromValue:[NSNumber numberWithFloat:1.0]];
    [animation setToValue:[NSNumber numberWithFloat:0]];
    [animation setDelegate:self];
    [self.animatView.layer addAnimation:animation forKey:@"firstView-Opacity"];
}
- (void) third_animations
{
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationRepeatCount:1];
    [UIView setAnimationDuration:1];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; 
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.containView cache:YES];
    [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:)];
    [UIView commitAnimations];
}
- (void) fourth_animations
{
    CATransition *transition = [CATransition animation];
    transition.duration = 1.0f;          /*  間隔時間*/
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];  /* 動畫的開始與結束的快慢*/
    transition.type = @"pageCurl";  //@"cube" @"moveIn" @"reveal" @"fade"(default) @"pageCurl" @"pageUnCurl" @"suckEffect" @"rippleEffect" @"oglFlip"
    transition.subtype = kCATransitionFromRight;
    transition.removedOnCompletion = YES;
    transition.fillMode = kCAFillModeBackwards;
    transition.delegate = self;
    [self.animatView.layer addAnimation:transition forKey:nil];  
}
-(void) resetView
{
    [self.animatView setTransform:CGAffineTransformRotate(self.animatView.transform, degreesToRadian(180))];
    self.animatView.frame = CGRectMake(0, 0, 280, 200);
}
#pragma mark Delegate Methods
- (void)animationDidStop:(CAAnimation *) theAnimation finished:(BOOL) flag {
    self.animatView.frame = CGRectMake(0, 0, 280, 200);
}

#define degreesToRadian(x) (M_PI * (x) / 180.0)
