接下来看base文件夹下的Quartz 文件夹内容
这个文件夹下的类不多
CALayer+YYAdd.h
YYCGUtilities
1.CALayer+YYAdd.h
好多函数和UIView 的重合，这里不做介绍了
- (CGFloat)transformRotation
- (void)setTransformRotation:(CGFloat)v
设置或者获取旋转角度
- (CGFloat)transformRotationX
- (void)setTransformRotationX:(CGFloat)v
设置或者获取x轴旋转角度
- (CGFloat)transformRotationY
- (void)setTransformRotationY:(CGFloat)v
设置或者获取y轴旋转角度
- (CGFloat)transformRotationZ
- (void)setTransformRotationZ:(CGFloat)v
设置或者获取z轴旋转角度
- (CGFloat)transformScaleX
- (void)setTransformScaleX:(CGFloat)v
- (CGFloat)transformScaleY
- (void)setTransformScaleY:(CGFloat)v
- (CGFloat)transformScaleZ
- (void)setTransformScaleZ:(CGFloat)v
xyz轴的缩放
- (CGFloat)transformScale
- (void)setTransformScale:(CGFloat)v
平面缩放
- (CGFloat)transformTranslationX
- (void)setTransformTranslationX:(CGFloat)v
- (CGFloat)transformTranslationY
- (void)setTransformTranslationY:(CGFloat)v
- (CGFloat)transformTranslationZ
- (void)setTransformTranslationZ:(CGFloat)v
平移
- (CGFloat)transformDepth {
return self.transform.m34;
}
- (void)setTransformDepth:(CGFloat)v {
CATransform3D d = self.transform;
d.m34 = v;
self.transform = d;
}
设置深度
这篇文章讲解什么是m34的。
- (UIViewContentMode)contentMode
- (void)setContentMode:(UIViewContentMode)contentMode
NSString *YYUIViewContentModeToCAGravity(UIViewContentMode contentMode) {
switch (contentMode) {
case UIViewContentModeScaleToFill: return kCAGravityResize;
case UIViewContentModeScaleAspectFit: return kCAGravityResizeAspect;
case UIViewContentModeScaleAspectFill: return kCAGravityResizeAspectFill;
case UIViewContentModeRedraw: return kCAGravityResize;
case UIViewContentModeCenter: return kCAGravityCenter;
case UIViewContentModeTop: return kCAGravityTop;
case UIViewContentModeBottom: return kCAGravityBottom;
case UIViewContentModeLeft: return kCAGravityLeft;
case UIViewContentModeRight: return kCAGravityRight;
case UIViewContentModeTopLeft: return kCAGravityTopLeft;
case UIViewContentModeTopRight: return kCAGravityTopRight;
case UIViewContentModeBottomLeft: return kCAGravityBottomLeft;
case UIViewContentModeBottomRight: return kCAGravityBottomRight;
default: return kCAGravityResize;
}
}
UIViewContentMode 和 kCAGravity 之间做的转换桥接
- (void)addFadeAnimationWithDuration:(NSTimeInterval)duration curve:(UIViewAnimationCurve)curve
- (void)removePreviousFadeAnimation
增加几种过度动画
YYCGUtilities.h
CGContextRef YYCGContextCreateARGBBitmapContext(CGSize size, BOOL opaque, CGFloat scale)
获取bitmap上下文context
这里opaque 要是yes 就没有透明度了
CGContextRef YYCGContextCreateGrayBitmapContext(CGSize size, CGFloat scale)
创建bitmap上下文，只有灰色的 。
CGFloat YYScreenScale()
获取scale
CGSize YYScreenSize()
获取屏幕大小
还有一些矩阵计算的东东不看了，有时间回来从新看的时候在学习吧，让剩下部分烂尾吧。
