iOS 常用的宏定义

长期更新维护

1、防止循环调用的weak、strong

#if DEBUG
#if __has_feature(objc_arc)
#define weakify(object) autoreleasepool{} __weak __typeof__(object) weak##_##object = object;
#else
#define weakify(object) autoreleasepool{} __block __typeof__(object) block##_##object = object;
#endif
#else
#if __has_feature(objc_arc)
#define weakify(object) try{} @finally{} {} __weak __typeof__(object) weak##_##object = object;
#else
#define weakify(object) try{} @finally{} {} __block __typeof__(object) block##_##object = object;
#endif
#endif
#endif

#ifndef strongify
#if DEBUG
#if __has_feature(objc_arc)
#define strongify(object) autoreleasepool{} __typeof__(object) object = weak##_##object;
#else
#define strongify(object) autoreleasepool{} __typeof__(object) object = block##_##object;
#endif
#else
#if __has_feature(objc_arc)
#define strongify(object) try{} @finally{} __typeof__(object) object = weak##_##object;
#else
#define strongify(object) try{} @finally{} __typeof__(object) object = block##_##object;
#endif
#endif
#endif

2、屏幕尺寸和iPhone X适配导航高度

#define KMAINSCREEN [UIScreen mainScreen].bounds.size
#define kIsIPhoneX (KMAINSCREEN.width == 375.f && KMAINSCREEN.height == 812.f)
#define kStatusBarAndNavigationBarHeight (kIs_iPhoneX ? 88.f : 64.f)

3、设置RGB颜色/设置RGBA颜色

#define XYRGBColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]
#define XYRGBAColor(r, g, b, a) [UIColor colorWithRed:(r)/255.0 green:(r)/255.0 blue:(r)/255.0 alpha:a]
#define XYRandomColor [UIColor colorWithRed:arc4random_uniform(256)/255.0 green:arc4random_uniform(256)/255.0 blue:arc4random_uniform(256)/255.0 alpha:1.0]

4、根据iphone6 的设计稿计算缩放高度

#define KIPhone6Space(designSpace) ((designSpace)*(KMAINSCREEN.width/667.0f)) 

5、沙盒目录路径

#define PathTemp NSTemporaryDirectory()//获取temp
#define PathDocument [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]//获取沙盒 Document
#define PathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject]//获取沙盒 Cache
