iOS開發常用宏總結

     在APP開發過程中經常會用到一些固定的常量或者統一的分類等，每個地方都去寫這種判斷表達式會讓代碼很臃腫且不易修改，整理下工作中常用的一些宏定義吧

 

//AppDelegate與本都存儲對象

#define kAppDelegate (AppDelegate *)[UIApplication sharedApplication].delegate

#define kUserDefaults  [NSUserDefaults standardUserDefaults]

//屏幕尺寸

#define kSCREEN_WIDTH ([UIScreen mainScreen].bounds.size.width)//屏幕寬度

#define kSCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)//屏幕高度

//機型判斷

//判斷是否是ipad

#define isPad ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)

//判斷iPhone4系列

#define kiPhone4 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)

//判斷iPhone5系列

#define kiPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)

//判斷iPhone6系列

#define kiPhone6 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(750, 1334), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)

//判斷iphone6+系列

#define kiPhone6Plus ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2208), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)

//判斷iPhoneX

#define IS_IPHONE_X ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)

//判斷iPHoneXr

#define IS_IPHONE_Xr ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)

//判斷iPhoneXs

#define IS_IPHONE_Xs ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)

//判斷iPhoneXs Max

#define IS_IPHONE_Xs_Max ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2688), [[UIScreen mainScreen] currentMode].size) && !isPad : NO)

//針對劉海屏狀態欄與底部區域高度計算

//IphoneX

#define isIphoneX ((IS_IPHONE_X==YES || IS_IPHONE_Xr ==YES || IS_IPHONE_Xs== YES || IS_IPHONE_Xs_Max== YES) ? YES : NO)

#define kNavigationHeight ((IS_IPHONE_X==YES || IS_IPHONE_Xr ==YES || IS_IPHONE_Xs== YES || IS_IPHONE_Xs_Max== YES) ? 88.0 : 64.0)

#define kSafeAreaBottomHeight (isIphoneX ? 34 : 0)

//顏色值

#define GetColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]//RGB顏色

#define GetRGBAColor(r, g, b, a) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:(a)/1.0]//RGBA顏色

//顯示默認圖片

#define PlaceholderImage [UIImage imageNamed:@"image_placeholder"]

//彈窗提示

#define ALERTMESAGE(msg) [[[UIAlertView alloc] initWithTitle:nil message:msg delegate:nil cancelButtonTitle:@"確定" otherButtonTitles:nil] show]

//弱引用
