旋轉(zhuǎn)：

CABasicAnimation *tAnimation =? [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];

//默認(rèn)是順時(shí)針效果，若將fromValue和toValue的值互換，則為逆時(shí)針效果

tAnimation.fromValue = [NSNumber numberWithFloat:0.f];

tAnimation.toValue =? [NSNumber numberWithFloat: M_PI *2];

//旋轉(zhuǎn)速度，數(shù)字越大旋轉(zhuǎn)越慢

tAnimation.duration? = 10;

tAnimation.autoreverses = NO;

tAnimation.fillMode =kCAFillModeForwards;

tAnimation.repeatCount = MAXFLOAT; //如果這里想設(shè)置成一直自旋轉(zhuǎn)，可以設(shè)置為MAXFLOAT，否則設(shè)置具體的數(shù)值則代表執(zhí)行多少次

[self.flowerView.layer addAnimation:tAnimation forKey:nil];

平移，有兩種方法，1是用定時(shí)器和animateWithDuration,2是用CABasicAnimation

1，

HomeViewController.m

self.cloudsTimer = [NSTimer scheduledTimerWithTimeInterval:5 target:self selector:@selector(moveCloudsAnimation) userInfo:nil repeats:YES];

- (void)moveCloudsAnimation {

?[self.cloudsView moveSelfView];

}

CloudsView.m

- (void)moveSelfView {

CGPoint point = self.center;

self.center = CGPointMake(-self.frame.size.width*0.5,point.y);

[UIView animateWithDuration:5 animations:^{

self.center = CGPointMake(Screen_Width+self.frame.size.width/2, point.y);

}];

}

2.和旋轉(zhuǎn)一樣，將key換成position即可

HomeViewController.m

CABasicAnimation *pAnimation =? [CABasicAnimation animationWithKeyPath:@"position"];

//默認(rèn)是順時(shí)針效果，若將fromValue和toValue的值互換，則為逆時(shí)針效果

pAnimation.fromValue = [NSValue valueWithCGPoint:CGPointMake(-Screen_Width/2, CGRectGetMidY(self.cloudsView.frame))];

pAnimation.toValue =? [NSValue valueWithCGPoint:CGPointMake(Screen_Width*1.5, CGRectGetMidY(self.cloudsView.frame))];

//旋轉(zhuǎn)速度，數(shù)字越大旋轉(zhuǎn)越慢

pAnimation.duration? = 20;

pAnimation.autoreverses = NO;

pAnimation.fillMode =kCAFillModeForwards;

pAnimation.repeatCount = MAXFLOAT; //如果這里想設(shè)置成一直自旋轉(zhuǎn)，可以設(shè)置為MAXFLOAT，否則設(shè)置具體的數(shù)值則代表執(zhí)行多少次

[self.cloudsView.layer addAnimation:pAnimation forKey:nil];
