iOS开发常见的宏定义（实用）

亲姐發表於 2019-7-12 14:01:00

<div class="cnblogs_code">
<pre> iOS开发过程中使用一些常用的宏可以提高开发效率，提高代码的重用性；将这些宏放到一个头文件里然后再放到工程中的-Prefix.pch文件中(或者直接放到-Prefix.pch中)直接可以使用,灰常方便。
做了一些分类和注释,可以根据自己习惯再添加或者删除或者修改这些宏进行使用。

#ifndef MacroDefinition_h
#define MacroDefinition_h
//AppDelegate

#define APPDELEGATE [(AppDelegate*)delegate]
//----------------------系统设备相关----------------------------
//获取设备屏幕尺寸
#define SCREEN_WIDTH (.bounds.size.width)
#define SCREEN_HEIGHT (.bounds.size.height)//应用尺寸
#define APP_WIDTH [applicationFrame].size.width
#define APP_HEIGHT [applicationFrame].size.height
//获取系统版本
#define IOS_VERSION [[ systemVersion] floatValue]
#define CurrentSystemVersion [ systemVersion]
#define isIOS4 ([[ systemVersion] intValue]==4)
#define isIOS5 ([[ systemVersion] intValue]==5)
#define isIOS6 ([[ systemVersion] intValue]==6)
#define isAfterIOS4 ([[ systemVersion] intValue]>4)
#define isAfterIOS5 ([[ systemVersion] intValue]>5)
#define isAfterIOS6 ([[ systemVersion] intValue]>6)
//获取当前语言
#define CurrentLanguage ([ objectAtIndex:0])

//判断是否 Phone 4/5/6 是否是iPad
#define Phone4 ( ? CGSizeEqualToSize(CGSizeMake(640, 960), [ currentMode].size) : NO)
#define Phone5 ( ? CGSizeEqualToSize(CGSizeMake(640, 1136), [ currentMode].size) : NO)
#define Phone6 ( ? CGSizeEqualToSize(CGSizeMake(750, 1334), [ currentMode].size) : NO)
#define Phone6Plus ( ? CGSizeEqualToSize(CGSizeMake(1242,2208), [ currentMode].size) : NO)
#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
//判断是真机还是模拟器
#if TARGET_OS_IPHONE
//iPhone Device
#endif
#if TARGET_IPHONE_SIMULATOR
//iPhone Simulator
#endif
//----------------------系统设备相关----------------------------

//----------------------内存相关----------------------------
//使用ARC和不使用ARC
#if __has_feature(objc_arc)
//compiling with ARC
#else
// compiling without ARC
#endif
//释放一个对象
#define SAFE_DELETE(P) if(P) { , P = nil; }
#define SAFE_RELEASE(x) ;x=nil
//----------------------内存相关----------------------------

//----------------------图片相关----------------------------
//读取本地图片
#define LOADIMAGE(file,ext) pathForResource:file ofType:ext]]
//定义UIImage对象
#define IMAGE(A) pathForResource:A ofType:nil]]
//定义UIImage对象
#define ImageNamed(_pointer)
//可拉伸的图片
#define ResizableImage(name,top,left,bottom,right) [ resizableImageWithCapInsets:UIEdgeInsetsMake(top,left,bottom,right)]
#define ResizableImageWithMode(name,top,left,bottom,right,mode) [ resizableImageWithCapInsets:UIEdgeInsetsMake(top,left,bottom,right) resizingMode:mode]
//建议使用前两种宏定义,性能高于后者
//----------------------图片相关----------------------------

//----------------------颜色相关---------------------------
// rgb颜色转换（16进制->10进制）
#define UIColorFromRGB(rgbValue)
// 获取RGB颜色
#define RGBA(r,g,b,a)
#define RGB(r,g,b) RGBA(r,g,b,1.0f)
//背景色
#define BACKGROUND_COLOR
//清除背景色
#define CLEARCOLOR
//----------------------颜色相关--------------------------

//----------------------其他----------------------------
//方正黑体简体字体定义
#define FONT(F)
//file
//读取文件的文本内容,默认编码为UTF-8
#define FileString(name,ext) [ initWithContentsOfFile:[ pathForResource:(name) ofType:(ext)] encoding:NSUTF8StringEncoding error:nil]
#define FileDictionary(name,ext) [ initWithContentsOfFile:[ pathForResource:(name) ofType:(ext)]]
#define FileArray(name,ext) [ initWithContentsOfFile:[ pathForResource:(name) ofType:(ext)]]
//G－C－D
#define BACK(block) dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), block)
#define MAIN(block) dispatch_async(dispatch_get_main_queue(),block)
//Alert
#define ALERT(msg) [[ initWithTitle:nil message:msg delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil] show]

//由角度获取弧度有弧度获取角度
#define degreesToRadian(x) (M_PI * (x) / 180.0)
#define radianToDegrees(radian) (radian*180.0)/(M_PI)
//----------------------其他-------------------------------

//----------------------视图相关----------------------------
//设置需要粘贴的文字或图片
#define PasteString(string) [ setString:string];
#define PasteImage(image) [ setImage:image];

//得到视图的left top的X,Y坐标点
#define VIEW_TX(view) (view.frame.origin.x)
#define VIEW_TY(view) (view.frame.origin.y)

//得到视图的right bottom的X,Y坐标点
#define VIEW_BX(view) (view.frame.origin.x + view.frame.size.width)
#define VIEW_BY(view) (view.frame.origin.y + view.frame.size.height )

//得到视图的尺寸:宽度、高度
#define VIEW_W(view)(view.frame.size.width)
#define VIEW_H(view)(view.frame.size.height)
//得到frame的X,Y坐标点
#define FRAME_TX(frame)(frame.origin.x)
#define FRAME_TY(frame)(frame.origin.y)
//得到frame的宽度、高度
#define FRAME_W(frame)(frame.size.width)
#define FRAME_H(frame)(frame.size.height)
//----------------------视图相关----------------------------

//---------------------打印日志--------------------------
//Debug模式下打印日志,当前行,函数名
#if DEBUG
#define DLog(FORMAT, ...) fprintf(stderr,"\nfunction:%s line:%d content:%s\n", __FUNCTION__, __LINE__, [ UTF8String]);
#else
#define NSLog(FORMAT, ...) nil

//Debug模式下打印日志,当前行,函数名并弹出一个警告
#ifdef DEBUG

//打印Frame
#define LogFrame(frame) NSLog(@"frame[X=%.1f,Y=%.1f,W=%.1f,H=%.1f",frame.origin.x,frame.origin.y,frame.size.width,frame.size.height)
