iOS开发——图形与动画篇OC篇&图层基本上动画

图层的一些基本动画效果

#define kRadianToDegrees (radian) (radian * 180.0) / (M_PI)

• ／／闪烁

[self.testView.layer addAnimation:[self opacityForever_Animation:0.5] forKey:nil];

• ／／移动

[self.testView.layer addAnimation:[self duration:3 move:[NSNumber numberWithInteger:200]] forKey:nil];

• ／／缩放

[self.testView.layer addAnimation:[self scale:[NSNumber numberWithInteger:1] orgin:[NSNumber numberWithInteger:3] durTimes:1 Rep:MAXFLOAT] forKey:nil] ;

• ／／组合

NSArray *myArray = [NSArray arrayWithObjects:[self opacityForever_Animation:0.5], [self duration:1.0f move:[NSNumber numberWithFloat:200.0f]], [self scale:[NSNumber numberWithFloat:1.0f] orgin:[NSNumber numberWithFloat:3.0f] durTimes:2.0f Rep:MAXFLOAT], nil];

[self.testView.layer addAnimation:[self groupAnimation:myArray durTimes:3.0f Rep:MAXFLOAT] forKey:nil];

• ／／路径

CGMutablePathRef myPah = CGPathCreateMutable();

CGPathMoveToPoint(myPah, nil,30, 77);

CGPathAddCurveToPoint(myPah, nil, 50, 50, 60, 200, 200, 200);//这里的是控制点。

[self.testView.layer addAnimation:[self keyframeAnimation:myPah durTimes:5 Rep:MAXFLOAT] forKey:nil];

• ／／旋转

[self.testView.layer addAnimation:[self rotation:2 degree:kRadianToDegrees(90) direction:1 repeatCount:MAXFLOAT] forKey:nil];

• ／／移除

[self.testView.layer removeAllAnimations];
