使用绘图,动画

1.

CGMutablePathRef starPath = CGPathCreateMutable();

CGPathMoveToPoint(starPath,NULL,100.0f, 100.0f);

CGPathAddLineToPoint(starPath, NULL, 100.0f, 280.0f);

CGPathAddLineToPoint(starPath, NULL, 260.0, 170.0);

CGPathAddLineToPoint(starPath, NULL, 60.0, 170.0);

CGPathAddLineToPoint(starPath, NULL, 220.0, 280.0);

CGPathCloseSubpath(starPath);//记得这一点

2.关键帧动画

1>关于位置

<CAAnimationDelegate>//如果监听动画的执行过程就要设置代理

CAKeyframeAnimation *animation = nil;

animation = [CAKeyframeAnimation animationWithKeyPath:@"position"];

[animation setDuration:10.0f];

[animation setDelegate:self];

[animation setPath:starPath];

CFRelease(starPath);//记得这一点

starPath = nil;

[[imageView layer] addAnimation:animation forKey:@"position"];

//比如监听动画执行完了

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag {

}

2>关于透明度

CAKeyframeAnimation *opAnim = [CAKeyframeAnimation animationWithKeyPath:@"opacity"];

opAnim.duration = 6.0;

opAnim.values =[NSArray arrayWithObjects: 

[NSNumber numberWithFloat:0.25],  

[NSNumber numberWithFloat:0.75], 

[NSNumber numberWithFloat:1.0],

nil]; 

opAnim.keyTimes = [NSArray arrayWithObjects:

  [NSNumber numberWithFloat:0.0], 

  [NSNumber numberWithFloat:0.5], 

  [NSNumber numberWithFloat:1.0], nil];

[view.layer addAnimation:opAnim forKey:@"animateOpacity"];

 3.基本动画

1>关于透明度

CABasicAnimation *opAnim = [CABasicAnimation animationWithKeyPath:@"opacity"];

opAnim.duration = 2.0;

opAnim.fromValue = [NSNumber numberWithFloat:.20];

opAnim.toValue= [NSNumber numberWithFloat:1.0];

opAnim.cumulative = YES;

opAnim.repeatCount = 2;

[view.layer addAnimation:opAnim forKey:@"animateOpacity"];

2>关于控件的大小位置的 

CGAffineTransform moveTransform = CGAffineTransformMakeTranslation(180, 200);

CABasicAnimation *moveAnim = [CABasicAnimation animationWithKeyPath:@"transform"];

moveAnim.duration = 6.0;

moveAnim.toValue= [NSValue valueWithCATransform3D:

CATransform3DMakeAffineTransform(moveTransform)];

[view.layer addAnimation:moveAnim forKey:@"animateTransform"];

3.首尾动画

1>.

[UIView beginAnimations:nil context:NULL];

CGAffineTransform moveTransform = CGAffineTransformMakeTranslation(180, 200);

view.layer.affineTransform=moveTransform;

[UIView commitAnimations];

2>.

[UIView beginAnimations:@"animationID" context:nil];

[UIView setAnimationDuration:1.5f];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

[UIView setAnimationRepeatAutoreverses:NO];

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES];

 [UIView setAnimationDidStopSelector:@selector(viewAnimationDone:)];//类似上面的代理监听动画的完成

[UIView commitAnimations];
