1.用来进行手机尺寸适配
#define iphone6P (XMGScreenH == 736)
#define iphone6 (XMGScreenH == 667)
#define iphone5 (XMGScreenH == 568)
#define iphone4 (XMGScreenH == 480)
#define LSWScreenH [UIScreen mainScreen].bounds.size.height
#define LSWScreenW [UIScreen mainScreen].bounds.size.width
2.随机色
#define LSWColor(r,g,b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1]
#define LSWGlobeColor LSWColor(215, 215, 215)
