实现 hex 数字的UIcolor 生成
#import "UIColor+extension.h"
@implementation UIColor (extension)
+ (instancetype) KAkA_colorWithHex:(u_int32_t) hex{
int red = (hex & 0xFF0000) >> 16 ;
int green = (hex & 0x00FF00) >> 8 ;
int blue = hex & 0x0000FF;
return [UIColor colorWithRed:red/255.0 green:green/255.0 blue:blue/255.0 alpha:1.0];
}
