IOS开发基础

+ (UIColor *)colorWithRed:(CGFloat)redgreen:(CGFloat)greenblue:(CGFloat)bluealpha:(CGFloat)alpha; 指定HSB，参数是：色调（hue），饱和的（saturation），亮度（brightness）

+ (UIColor *)colorWithHue:(CGFloat)huesaturation:(CGFloat)saturationbrightness:(CGFloat)brightnessalpha:(CGFloat)alpha;

在自定义View的时候 设置蒙版的颜色可以这样弄，蒙版用一个UIImageView来做 kenshin笔记

CGFloatR  = (CGFloat) 225/255.0;
CGFloatG = (CGFloat) 66/255.0;
CGFloatB = (CGFloat) 88/255.0;
CGFloat alpha = (CGFloat) 1.0;
    
UIColor *myColorRGB = [ UIColorcolorWithRed:Rgreen:Gblue:Balpha: alpha  ];
self.tableView.backgroundColor = myColorRGB;

3.IOS禁止横屏

对键盘的隐藏——点击空白处隐藏、点击return键隐藏

键盘出现时，后面的视图整体上移的方法

3.IOS禁止横屏(两种方式) 可以通过 cmd ＋右 方向键 在模拟器中测试
