前言

开发中,常有快捷的一些宏定义,使得我们编程更方便 以下,是我自己整理的一些,希望对大伙有帮助:

1.获取设备有关 屏幕尺寸 以及 比例

#define IS_IPHONE_5_5 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )736 ) < DBL_EPSILON )
#define IS_IPHONE_4_7 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )667 ) < DBL_EPSILON )
#define IS_IPHONE_4_0 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )
#define IS_IPHONE_3_5 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )480 ) < DBL_EPSILON )

//常用设备宽高宏
#define ScreenWidth [[UIScreen mainScreen] bounds].size.width
#define ScreenHeight [[UIScreen mainScreen] bounds].size.height
#define Is_Iphone (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define Is_Iphone_X (Is_Iphone && ScreenHeight == 812.0)
#define NavBarHeight (Is_Iphone_X ? 88 : 64)
#define StatusBarHeight (Is_Iphone_X ? 24 : 0)
#define TabbarHeight (Is_Iphone_X ? 83 : 49)
#define SafeBottomHeight (Is_Iphone_X ? 34 : 0)
#define kStatusBarHeight [[UIApplication sharedApplication] statusBarFrame].size.height //状态栏高度。 iPhone X 之前是 20 iPhone X 是 44

//  判断是否是ipad
#define kIsIPad \
([[UIDevice currentDevice] respondsToSelector:@selector(userInterfaceIdiom)]\
&& [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)

// 判断当前定位是否为横向。
#define kIsLandscape (UIInterfaceOrientationIsLandscape([[UIApplication sharedApplication] statusBarOrientation]))


//快速获取window
#define KeyWindow       [[UIApplication sharedApplication] keyWindow]

2. 根据UI出的比例计算高度宽度(适配机型)

#define SWWidthProportion ScreenWidth/375
#define SWHeightProportion ScreenHeight/667

//单图屏幕宽高机型比列 w-屏幕宽 uiH-UI给出高度标注 uiW-UI给出宽度标注
#define SWImageHeightProportion(w,uiH,uiW) (w)*uiH/uiW

3. iPhoneX 系列

//判断是否是ipad
#define isIPad ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
//判断iPHoneXr
#define IS_IPHONE_Xr ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size) && !isIPad : NO)
//判断iPhoneXs
#define IS_IPHONE_Xs ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) && !isIPad : NO)
//判断iPhoneXs Max
#define IS_IPHONE_Xs_Max ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2688), [[UIScreen mainScreen] currentMode].size) && !isIPad : NO)

4. 加载字体大小

// 设置常规字体大小
#define kFontWithSize(size) [UIFont systemFontOfSize:size]
// 设置加粗字体大小
#define kBoldFontWithSize(size) [UIFont boldSystemFontOfSize:size]

5. 加载图片

// 加载本地图片
#define kImageName(Name) ([UIImage imageNamed:Name])
// 通过路径加载本地图片
#define kImageOfFile(Name) ([UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:Name ofType:nil]])

6. System Singletons 单例

// 偏好设置单例
#define kUserDefaults [NSUserDefaults standardUserDefaults]
//通知单例
#define kNotificationCenter  [NSNotificationCenter defaultCenter]
//文件管理单例
#define kFileManager [NSFileManager defaultManager]
// 简化通知
#define kPostNotificationWithName(notificationName) \
[kNotificationCenter postNotificationName:notificationName object:nil userInfo:nil]
// 简化通知(带参数)
#define kPostNotificationWithNameAndUserInfo(notificationName, userInfo) \
[kNotificationCenter postNotificationName:notificationName object:nil userInfo:userInfo]
//单例快速
#define CREATE_SHARED_MANAGER(CLASS_NAME) \
+ (instancetype)sharedManager { \
static CLASS_NAME *_instance; \
static dispatch_once_t onceToken; \
dispatch_once(&onceToken, ^{ \
_instance = [[CLASS_NAME alloc] init]; \
}); \
\
return _instance; \
}

7.Judge 判断

// 判断它是否是空字符串1.
#define kIsEmptyString(s) (s == nil || [s isKindOfClass:[NSNull class]] || ([s isKindOfClass:[NSString class]] && s.length == 0))
//判断它是否是空字符串2。
#define kStringIsEmpty(str) ([str isKindOfClass:[NSNull class]] || str == nil || [str length] < 1 ? YES : NO )
// 判断它是否为nil或null对象。
#define kIsEmptyObject(obj) (obj == nil || [obj isKindOfClass:[NSNull class]])
// 判断它是否是一个有效的字典。
#define kIsDictionary(objDict) (objDict != nil && [objDict isKindOfClass:[NSDictionary class]])
// 判断它是否是一个有效的数组。
#define kIsArray(objArray) (objArray != nil && [objArray isKindOfClass:[NSArray class]])

8.XIB 快速加载

#define LOADNIBWITHNAME(CLASS, OWNER) [[[NSBundle mainBundle] loadNibNamed:CLASS owner:OWNER options:nil] lastObject]

9.弱引用/强引用

//弱引用
#define weakSelf(object)            __weak typeof(object) weakSelf = object
#define SWWeakSelf(type)  __weak typeof(type) weak##type = type;
//强引用
#define SWStrongSelf(type)  __strong typeof(type) type = weak##type;

10.设置圆角边框

#define ATViewBorderRadius(View, Radius, Width, Color)\
\
[View.layer setCornerRadius:(Radius)];\
[View.layer setMasksToBounds:YES];\
[View.layer setBorderWidth:(Width)];\
[View.layer setBorderColor:[Color CGColor]]\

//设置圆角
#define ATViewRadius(View, Radius)\
\
[View.layer setCornerRadius:(Radius)];\
[View.layer setMasksToBounds:YES];\

11.设置按钮通用效果

//图片按压效果
#define ATBtnColorTool(View)\
[View setBackgroundImage:[UIImage imageNamed:@"未选中图片名"] forState:UIControlStateNormal];\
[View setBackgroundImage:[UIImage imageNamed:@"高亮图片名"]  forState:UIControlStateHighlighted];\
[View setBackgroundImage: [UIImage imageNamed:@"选中图片名"] forState:UIControlStateSelected];\

//颜色按压效果
#define ATBtnColorEnableTool(View)\
[View setBackgroundImage:[UIImage imageWithColor:ATMainEnabledColor] forState:UIControlStateNormal];\
[View setBackgroundImage:[UIImage imageWithColor:ATMainEnabledColor]  forState:UIControlStateHighlighted];\
[View setBackgroundImage: [UIImage imageWithColor:ATMainEnabledColor] forState:UIControlStateSelected];\

12.颜色

//宏定义
#define UIColorRGBA(_red, _green, _blue, _alpha) [UIColor colorWithRed:((_red)/255.0) \
green:((_green)/255.0) blue:((_blue)/255.0) alpha:(_alpha)]
#define UIColorRGB(red, green, blue) UIColorRGBA(red, green, blue, 1)
#define UIColorHexRGB(rgbString) [UIColor colorWithHexRGB:(rgbString)]
#define UIColorHexRGBA(rgbaString) [UIColor colorWithHexRGBA:(rgbaString)]

13.快速设置tableView 间距写法 带有头部14像素点(适配iphoneX)

#define ATTableViewHeadFooterLineSetting  - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {   return 14; }\
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{  return [UIView new];}\
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section{ return 0.01f; }\
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section{ return [UIView new]; } \

14.GCD

//GCD - 一次性执行
#define kDISPATCH_ONCE_BLOCK(onceBlock) static dispatch_once_t onceToken; dispatch_once(&onceToken, onceBlock);

//GCD - 在Main线程上运行
#define kDISPATCH_MAIN_THREAD(mainQueueBlock) dispatch_async(dispatch_get_main_queue(), mainQueueBlock);

//GCD - 开启异步线程
#define kDISPATCH_GLOBAL_QUEUE_DEFAULT(globalQueueBlock) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), globalQueueBlocl);

GCD宏定义使用

//输出

#define SWLog( s, ... ) NSLog( @"< %@:(%d) > %@", [[NSString stringWithUTF8String:__FILE__] lastPathComponent], __LINE__, [NSString stringWithFormat:(s), ##__VA_ARGS__] )
