参考别人的定义:

1.获取屏幕宽度与高度

 #define SCREEN_WIDTH   [UIScreen mainScreen].bounds.size.width
#define SCREENH_HEIGHT [UIScreen mainScreen].bounds.size.height //iOS8以后,设备横屏,[UIScreen mainScreen].bounds.size的值是宽大于高的,即iOS8以后这个值跟屏幕方向有关了 #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000 // 当前Xcode支持iOS8及以上 #define SCREEN_WIDTH ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)]?[UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale:[UIScreen mainScreen].bounds.size.width) #define SCREENH_HEIGHT ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)]?[UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale:[UIScreen mainScreen].bounds.size.height) #define SCREEN_SIZE ([[UIScreen mainScreen] respondsToSelector:@selector(nativeBounds)]?CGSizeMake([UIScreen mainScreen].nativeBounds.size.width/[UIScreen mainScreen].nativeScale,[UIScreen mainScreen].nativeBounds.size.height/[UIScreen mainScreen].nativeScale):[UIScreen mainScreen].bounds.size) #else #define SCREEN_WIDTH [UIScreen mainScreen].bounds.size.width #define SCREENH_HEIGHT [UIScreen mainScreen].bounds.size.height #define SCREEN_SIZE [UIScreen mainScreen].bounds.size #endif 
2.获取通知中心
#define LRNotificationCenter [NSNotificationCenter defaultCenter]
3.设置随机颜色
#define LRRandomColor [UIColor colorWithRed:arc4random_uniform(256)/255.0 green:arc4random_uniform(256)/255.0 blue:arc4random_uniform(256)/255.0 alpha:1.0]
4.设置RGB颜色/设置RGBA颜色
#define LRRGBColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]
#define LRRGBAColor(r, g, b, a) [UIColor colorWithRed:(r)/255.0 green:(r)/255.0 blue:(r)/255.0 alpha:a]
// clear背景颜色
#define LRClearColor [UIColor clearColor]
5.自定义高效率的 NSLog

项目开发中,我们会在许多地方加上Log,但是发布的时候又不想用这些Log,我们也不可能一个一个的删除,所以自定义Log是必然的!

#ifdef DEBUG
#define LRLog(...) NSLog(@"%s 第%d行 \n %@\n\n",__func__,__LINE__,[NSString stringWithFormat:__VA_ARGS__])
#else
#define LRLog(...)

#endif
6.弱引用/强引用
#define LRWeakSelf(type) __weak typeof(type) weak##type = type;
#define LRStrongSelf(type) __strong typeof(type) type = weak##type;

第二种使用方法,定义完弱引用宏之后,直接敲weak.png
7.设置 view 圆角和边框
#define LRViewBorderRadius(View, Radius, Width, Color)\
\
[View.layer setCornerRadius:(Radius)];\
[View.layer setMasksToBounds:YES];\
[View.layer setBorderWidth:(Width)];\
[View.layer setBorderColor:[Color CGColor]]
8.由角度转换弧度 由弧度转换角度
#define LRDegreesToRadian(x) (M_PI * (x) / 180.0) #define LRRadianToDegrees(radian) (radian*180.0)/(M_PI)
9.设置加载提示框(第三方框架:Toast)

此宏定义非常好用,但是小伙伴需要CocoaPods导入第三方框架:Toast

使用方法如下:
LRToast(@"网络加载失败");

#define LRToast(str)              CSToastStyle *style = [[CSToastStyle alloc] initWithDefaultStyle]; \ [kWindow  makeToast:str duration:0.6 position:CSToastPositionCenter style:style];\ kWindow.userInteractionEnabled = NO; \ dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.6 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{\ kWindow.userInteractionEnabled = YES;\ });\
10.设置加载提示框(第三方框架:MBProgressHUD)

此宏定义同上一个类似,如下图:

[置顶] 常使用的宏定义归类(新添加的一些)_第3张图片
MBProgressHUD提示框.png
// 加载
#define kShowNetworkActivityIndicator() [UIApplication sharedApplication].networkActivityIndicatorVisible = YES
// 收起加载
#define HideNetworkActivityIndicator() [UIApplication sharedApplication].networkActivityIndicatorVisible = NO
// 设置加载
#define NetworkActivityIndicatorVisible(x) [UIApplication sharedApplication].networkActivityIndicatorVisible = x

#define kWindow [UIApplication sharedApplication].keyWindow

#define kBackView for (UIView *item in kWindow.subviews) { \ if(item.tag == 10000) \ { \ [item removeFromSuperview]; \ UIView * aView = [[UIView alloc] init]; \ aView.frame = [UIScreen mainScreen].bounds; \ aView.tag = 10000; \ aView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.3]; \ [kWindow addSubview:aView]; \ } \ } \ 
#define kShowHUDAndActivity kBackView;[MBProgressHUD showHUDAddedTo:kWindow animated:YES];kShowNetworkActivityIndicator()

#define kHiddenHUD [MBProgressHUD hideAllHUDsForView:kWindow animated:YES]

#define kRemoveBackView for (UIView *item in kWindow.subviews) { \ if(item.tag == 10000) \ { \ [UIView animateWithDuration:0.4 animations:^{ \ item.alpha = 0.0; \ } completion:^(BOOL finished) { \ [item removeFromSuperview]; \ }]; \ } \ } \ 
#define kHiddenHUDAndAvtivity kRemoveBackView;kHiddenHUD;HideNetworkActivityIndicator()
11.获取view的frame/图片资源
//获取view的frame
#define kGetViewWidth(view) view.frame.size.width
#define kGetViewHeight(view) view.frame.size.height
#define kGetViewX(view) view.frame.origin.x
#define kGetViewY(view) view.frame.origin.y

//获取图片资源
#define kGetImage(imageName) [UIImage imageNamed:[NSString stringWithFormat:@"%@",imageName]]
12.获取当前语言
#define LRCurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])
13.使用 ARC 和 MRC
#if __has_feature(objc_arc)
// ARC
#else
// MRC
#endif
14.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))
15.判断是真机还是模拟器
#if TARGET_OS_IPHONE 
//iPhone Device 
#endif 

#if TARGET_IPHONE_SIMULATOR 
//iPhone Simulator 
#endif
16.沙盒目录文件
//获取temp
#define kPathTemp NSTemporaryDirectory()

//获取沙盒 Document
#define kPathDocument [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]

//获取沙盒 Cache
#define kPathCache [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject]
17.GCD 的宏定义

很多小伙伴都非常烦写GCD的方法,所以在此定义为宏使用更加方便简洁!如下图:

[置顶] 常使用的宏定义归类(新添加的一些)_第4张图片
GCD 宏使用方法.png
//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);

宏与const 的使用:

很多小伙伴在定义一个常量字符串,都会定义成一个宏,最典型的例子就是服务器的地址。在此所有用宏定义常量字符的小伙伴以后就用const来定义吧!为什么呢 ?我们看看:

  • 宏的用法: 一般字符串抽成宏,代码抽成宏使用。
  • const用法:一般常用的字符串定义成const(对于常量字符串苹果推荐我们使用const)。
  • 宏与const区别:
    1.编译时刻不同,宏属于预编译 ,const属于编译时刻
    2.宏能定义代码,const不能,多个宏对于编译会相对时间较长,影响开发效率,调试过慢,const只会编译一次,缩短编译时间。
    3.宏不会检查错误,const会检查错误

通过以上对比,我们以后在开发中如果定义一个常量字符串就用const,定义代码就用宏。我们来看看如何使用const,列举实际项目使用方法如下图:


FANCommonConst.h中声明一个常量字符串.png

FANCommonConst.m中实现一个常量字符串.png


在上图本人只是简单定义几个常量字符串,我们创建一个类只要在.h.m中包含#import <Foundation/Foundation.h>就可以,然后再.h文件声明一个字符串,在.m中实现就可以了,最后把这个类导入PCH文件中,我们就可任意的发挥啦!
