iOS 通用宏定义总结

为了方便开发，经常会用到一些宏定义。梳理了之前项目中用到的，又查漏补缺挑选了一些网络上比较不错的，总结了一份分享给大家。

//1,***获取系统对象

#define kApplication        [UIApplication sharedApplication]

#define kUserDefaults       [NSUserDefaults standardUserDefaults]

#define kNotificationCenter [NSNotificationCenter defaultCenter]

//2,***获取屏幕宽高

#define kScreenWidth ([[UIScreen mainScreen] bounds].size.width)

#define kScreenHeight [[UIScreen mainScreen] bounds].size.height

#define kScreen_Bounds [UIScreen mainScreen].bounds

//3,***根据ip6的屏幕来拉伸

#define kRealWidth(with) ((with)*(KScreenWidth/375.0f))

#define kRealHeight(height) ((height)*(kScreenHeight/667.0f))

//4,***强弱引用(执行完A ## B后变为AB(连接A和B并去掉空格)

#define kWeakSelf(type)  __weak typeof(type) weak##type = type;

#define kStrongSelf(type) __strong typeof(type) type = weak##type;

//5,***View圆角和加边框

#define ViewBorderRadius(View, Radius, Width, Color)\

\

[View.layer setCornerRadius:(Radius)];\

[View.layer setMasksToBounds:YES];\

[View.layer setBorderWidth:(Width)];\

[View.layer setBorderColor:[Color CGColor]]

//6,***View圆角

#define ViewRadius(View, Radius)\

\

[View.layer setCornerRadius:(Radius)];\

[View.layer setMasksToBounds:YES]

//7,***颜色

#define UIColorWithRGBA(r,g,b,a) [UIColor colorWithRed:(r) / 255.0f green:(g) / 255.0f blue:(b) / 255.0f alpha:(a)]

#define UIColorWithRGBValue(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

//随机色生成

#define kRandomColor    UIColorWithRGBA(arc4random_uniform(256),arc4random_uniform(256),arc4random_uniform(256),1)   

//8,***字体

#define BoldSystemFont(fontSize) [UIFont boldSystemFontOfSize:fontSize]

#define SystemFont(fontSize)   [UIFont systemFontOfSize:fontSize]

#define FONT(fontName, fontSize) [UIFont fontWithName:(fontName) size:(fontSize)]

//9,***当前系统版本(iOS版本)

#define CurrentSystemVersion [[UIDevice currentDevice].systemVersion doubleValue]

//10,***发送通知

#define KPostNotification(name,obj) [[NSNotificationCenter defaultCenter] postNotificationName:name object:obj];

//11,***DEBUG 模式下打印日志,当前行

#ifdef DEBUG

#define DLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);

#else

#define DLog(...)

#endif
