OC对象判断是否为空？
- 字符串是否为空
#define kStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] || str == nil || [str length] < 1 ? YES : NO )- 数组是否为空
#define kArrayIsEmpty(array) (array == nil || [array isKindOfClass:[NSNull class]] || array.count == 0)- 字典是否为空
#define kDictIsEmpty(dic) (dic == nil || [dic isKindOfClass:[NSNull class]] || dic.allKeys == 0)- 是否是空对象
#define kObjectIsEmpty(_object) (_object == nil || [_object isKindOfClass:[NSNull class]] || ([_object respondsToSelector:@selector(length)] && [(NSData *)_object length] == 0) || ([_object respondsToSelector:@selector(count)] && [(NSArray *)_object count] == 0))
UI尺寸类的宏
- 状态栏高度
#define STATUS_BAR_HEIGHT 20- NavBar导航栏高度
#define NAVIGATION_BAR_HEIGHT 44- 状态栏 ＋ 导航栏 高度
#define STATUS_AND_NAVIGATION_HEIGHT ((STATUS_BAR_HEIGHT) + (NAVIGATION_BAR_HEIGHT))- 屏幕 rect
#define SCREEN_RECT ([UIScreen mainScreen].bounds) #define SCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width) #define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height) #define CONTENT_HEIGHT (SCREEN_HEIGHT - NAVIGATION_BAR_HEIGHT - STATUS_BAR_HEIGHT)- 屏幕分辨率
#define SCREEN_RESOLUTION (SCREEN_WIDTH * SCREEN_HEIGHT * ([UIScreen mainScreen].scale))
LOG日志打印
- 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- 重写NSLog,Debug模式下打印日志和当前行数
#if DEBUG #define NSLog(FORMAT, ...) fprintf(stderr,"\nfunction:%s line:%d content:%s\n", __FUNCTION__, __LINE__, ［NSString stringWithFormat:FORMAT, ##__VA_ARGS__] UTF8String]); #else #define NSLog(FORMAT, ...) nil #endif- DEBUG 模式下打印日志,当前行 并弹出一个警告
#ifdef DEBUG # define ULog(fmt, ...) { UIAlertView *alert = ［UIAlertView alloc] initWithTitle:[NSString stringWithFormat:@"%s\n [Line %d] ", __PRETTY_FUNCTION__, __LINE__] message:[NSString stringWithFormat:fmt, ##__VA_ARGS__] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; } #else # define ULog(...) #endif
判断设备？系统？
- 是否iPad
#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)- 是否iPad
#define someThing (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)? ipad: iphone- 获取系统版本
#define IOS_VERSION ［[UIDevice currentDevice] systemVersion] floatValue] #define CurrentSystemVersion ［UIDevice currentDevice] systemVersion]- 判断是否 Retina屏?
#define isRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), ［UIScreen mainScreen] currentMode].size) : NO)
判断当前的iPhone设备/系统版本
- 判断是否为iPhone
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)- 判断是否为iPad
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)- 判断是否为ipod
#define IS_IPOD ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])- 判断是否为 iPhone 5SE
#define iPhone5SE [[UIScreen mainScreen] bounds].size.width == 320.0f && [[UIScreen mainScreen] bounds].size.height == 568.0f- 判断是否为iPhone 6/6s
#define iPhone6_6s [[UIScreen mainScreen] bounds].size.width == 375.0f && [[UIScreen mainScreen] bounds].size.height == 667.0f- 判断是否为iPhone 6Plus/6sPlus
#define iPhone6Plus_6sPlus [[UIScreen mainScreen] bounds].size.width == 414.0f && [[UIScreen mainScreen] bounds].size.height == 736.0f- 获取系统版本
#define IOS_SYSTEM_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]- 判断 iOS 8 或更高的系统版本
#define IOS_VERSION_8_OR_LATER (([[[UIDevice currentDevice] systemVersion] floatValue] >=8.0)? (YES):(NO))- 判断设备的操做系统是不是ios7
#define IOS7 (［[UIDevice currentDevice].systemVersion doubleValue] >= 7.0]- 判断是真机还是模拟器
#if TARGET_OS_IPHONE //iPhone Device #endif #if TARGET_IPHONE_SIMULATOR //iPhone Simulator #endif- 检查系统版本
#define SYSTEM_VERSION_EQUAL_TO(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame) #define SYSTEM_VERSION_GREATER_THAN(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending) #define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending) #define SYSTEM_VERSION_LESS_THAN(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending) #define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v) (［[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)
