ios中的各中動畫（旋轉，平移）

//圖片進行自動旋轉

CABasicAnimation是一個最多隻能有兩個主要畫面格的動畫，

UIImageView *imageView = [[UIImageViewalloc]initWithImage:[UIImageimageNamed:@"7"]];

imageView.frame =CGRectMake(40, 60,200, 250);

[self.viewaddSubview:imageView];

CABasicAnimation *animation = [CABasicAnimationanimationWithKeyPath:@"transform"];

animation.delegate =self;

animation.toValue = [NSValuevalueWithCATransform3D:CATransform3DMakeRotation(M_PI,0, 0,1.0)];

//執行時間

animation.duration =30;

animation.cumulative =YES;//累積的

//執行次數

animation.repeatCount = INT_MAX;

animation.autoreverses=YES;//是否自動重複

[imageView.layeraddAnimation:animation forKey:@"animation"];

通過CATransition實作類別似UINavigationController的pushview及Popview效果

CATransition動畫使用了類型type和子類型subtype兩個概念。type屬性指定了過渡的種類（淡化、推擠、揭開、覆蓋）。subtype設定了過渡的方向（從上、下、左、右）。另外，CATransition私人的動畫類型有（立方體、吸收、翻轉、波紋、翻頁、反翻頁、鏡頭開、鏡頭關）。

/* CATransition *myT = [ CATransition animation];

myT.timingFunction = UIViewAnimationCurveEaseInOut;

myT.type = @"cube";

//動畫類型

// 1 kCATransitionFromBottom

// 2 kCATransitionFromLeft

// 3 kCATransitionFromTop

// 4 kCATransitionFromRight

//myT.subtype = kCATransitionFromLeft;

myT.subtype = kCATransitionFromLeft;

myT.duration = 0.5;

[self.navigationController.view.layer addAnimation: myT forKey:nil];

NSLog(@"app");*/

建立UIView動畫（塊）——（指過渡效果的動畫）

//方法一：

//過度動畫的效果，是2個View的切換

- (void)viewDidLoad

{

[superviewDidLoad];

UIButton* button12 = [[UIButtonalloc]initWithFrame:CGRectMake(20,340, 150, 30)];

[button12 addTarget:self action:@selector(button22)forControlEvents:UIControlEventTouchUpInside];

[button12 setTitle:@"開始動畫" forState:UIControlStateNormal];

button12.backgroundColor = [UIColorredColor];

[self.viewaddSubview:button12];

//方法二：

// 2 用block文法實現

/* [UIView animateWithDuration:0.5 animations:^{

CGRect frames = self.view_1.frame;

frames.origin.x = 160;

self.view_1.frame = frames;

//縮放

self.view_1.transform = CGAffineTransformScale(self.view_1.transform, 0.01, 0.01);

}completion:^(BOOL finished) {

CGRect frames = self.view_1.frame;

frames.origin.x = 0;

self.view_1.frame = frames;

//恢複到原始的縮放

self.view_1.transform = CGAffineTransformIdentity;

}];*/

}

-(void)button22

{

//開始動畫

[UIViewbeginAnimations:@"testanimation"context:nil];

[UIViewsetAnimationDuration:0.5];

//代理

[UIViewsetAnimationDelegate:self];

//動畫的響應事件，使視圖自動回到原來的位置

[UIViewsetAnimationDidStopSelector:@selector(animationstop)];

[UIViewsetAnimationCurve:UIViewAnimationCurveEaseInOut];

//獲得視圖的位置

CGRect frames =self.view_1.frame;

frames.origin.x =160;

self.view_1.frame = frames;

[UIViewcommitAnimations];

}

-(void)animationstop

{

[UIViewbeginAnimations:nilcontext:nil];

[UIViewsetAnimationDuration:0.5];

CGRect frames =self.view_1.frame;

frames.origin.x =0;

self.view_1.frame = frames;

[UIViewcommitAnimations];
