iOS中有时候UI给的一个色号就像 #54e1b7 这个,而我们一般设置颜色都是根据RBG来设置的,所以这里需要把这个16进制的色号转为RGB值,这里我们就使用一下的方法来调用设置颜色. + (UIColor *)getColor:(NSString *)hexColor { ) { NSLog(@"color string is nil."); return [UIColor blackColor]; } unsigned int red,green,blue; NSRange ra…

目前ios的指令集有以下几种: 1,armv6,支持的机器iPhone,iPhone2,iPhone3G及对应的iTouch 2,armv7,支持的机器iPhone4,iPhone4S 3,armv7s,支持的机器iPhone5,iPhone5C 4,arm64,支持的机器:iPhone5S 机器对指令集的支持是向下兼容的,因此armv7的指令集是可以运行在iphone5S的,只是效率没那么高而已~ ======================== Architecture : 指你想支持的指令…

项目中经常会用到颜色转换,有的是通过十六进制转成数字转颜色,想简单的点直接通过字符串转一下,简单扩展了一下分类UIColor,代码如下: +(UIColor *)colorWithHex:(NSString *)hexColor{ return [self colorWithHex:hexColor alpha:1.0f]; } //http://www.cnblogs.com/xiaofeixiang iOS技术交流:228407086 +(UIColor *)colorWithHex:(NS…
