在工作中, 很多小伙伴都会在PCH文件定义一些常用的宏,但是又怕写这些简单的宏浪费时间,又有时候忘记怎么定义了怎么办?本人在工作中也是如此。所以在这里给大家分享一些常用的宏定义,喜欢的小伙伴可以直接在项目中使用(持续更新)!
为了大家使用方便,请点击GitHub - 宏定义头文件下载 !
#define SCREEN_WIDTH [UIScreen mainScreen].bounds.size.width
#define SCREENH_HEIGHT [UIScreen mainScreen].bounds.size.height
#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
#define LRNotificationCenter [NSNotificationCenter defaultCenter]
#define LRRandomColor [UIColor colorWithRed:arc4random_uniform(256)/255.0 green:arc4random_uniform(256)/255.0 blue:arc4random_uniform(256)/255.0 alpha:1.0]
#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]
#ifdef DEBUG
#define LRLog(...) NSLog(@"%s 第%d行 \n %@\n\n",__func__,__LINE__,[NSString stringWithFormat:__VA_ARGS__])
#else
#define LRLog(...)
#endif
#define LRWeakSelf(type) __weak typeof(type) weak##type = type;
#define LRStrongSelf(type) __strong typeof(type) type = weak##type;
#define LRViewBorderRadius(View, Radius, Width, Color)\
[View.layer setCornerRadius:(Radius)];[View.layer setMasksToBounds:YES];[View.layer setBorderWidth:(Width)];[View.layer setBorderColor:[Color CGColor]]
#define LRDegreesToRadian(x) (M_PI * (x) / 180.0)
#define LRRadianToDegrees(radian) (radian*180.0)/(M_PI)
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;});\
// 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()
//获取view的frame(不建议使用)
//#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]]
#define LRCurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])
#if __has_feature(objc_arc)
// ARC
#else

#endif
//判断是否为iPhone

#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))
#if TARGET_OS_IPHONE
//iPhone Device
#endif
#if TARGET_IPHONE_SIMULATOR
//iPhone Simulator
#endif
//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]
//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:
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)。
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和.m中包含#import
