ios常用宏定义

[code]//------------------------单利宏定义--------------------------

#define IMPLEMENT_SINGLETON(class)\
+ (instancetype)shared##class {\
    static class* shared##class = nil;\
    static dispatch_once_t onceToken;\
    dispatch_once(&onceToken, ^{\
        shared##class = [[self alloc] init];\
    });\
    return shared##class;\
}
    //单利的使用方法，直接里面加类名就可以了
 IMPLEMENT_SINGLETON(AppManager)

//-----------------------UIView 一些操作方法**-----------------

#define ScreenWidth    [[UIScreen mainScreen] bounds].size.width
#define ScreenHeight   [[UIScreen mainScreen] bounds].size.height
#define iOSVersion     [[UIDevice currentDevice].systemVersion floatValue]
 #define CGRectSetWidth(rect, width)  CGRectMake(rect.origin.x,     rect.origin.y, width, rect.size.height)
#define CGRectSetHeight(rect, height)   CGRectMake(rect.origin.x, rect.origin.y, rect.size.width, height)
#define CGRectSetSize(rect, size)       CGRectMake(rect.origin.x, rect.origin.y, size.width, size.height)

#define ViewSetOrigin(view, origin)     view.frame = CGRectSetOrigin(view.frame, origin);

//----------------------system----------------------------  

//获取系统版本  
#define IOS_VERSION [[[UIDevice currentDevice] systemVersion] floatValue]  
#define CurrentSystemVersion [[UIDevice currentDevice] systemVersion] 
//获取当前语言  
#define CurrentLanguage ([[NSLocale preferredLanguages] objectAtIndex:0])  
//判断是否 Retina屏、设备是否%fhone 5、是否是iPad  
#define isRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) : NO)  
#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO)  
#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)  

//----------------------图片----------------------------  

//读取本地图片  
#define LOADIMAGE(file,ext) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:file ofType:ext]]  

//定义UIImage对象  
#define IMAGE(A) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:A ofType:nil]]  

//定义UIImage对象  
#define ImageNamed(_pointer) [UIImage imageNamed:[UIUtil imageName:_pointer]]  

//建议使用前两种宏定义,性能高于后者  
// rgb颜色转换（16进制->10进制）  
#define UIColorFromRGB(rgbValue) [UIColor colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 green:((float)((rgbValue & 0xFF00) >> 8))/255.0 blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]  

//带有RGBA的颜色设置  
#define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]  
//file
//读取文件的文本内容,默认编码为UTF-8
#define FileString(name,ext)    [[NSString alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:(name) ofType:(ext)] encoding:NSUTF8StringEncoding error:nil]
#define FileDictionary(name,ext)    [[NSDictionary alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:(name) ofType:(ext)]]
#define FileArray(name,ext)     [[NSArray alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:(name) ofType:(ext)]]
//App
#define kApp ((AppDelegate *)[UIApplication sharedApplication].delegate)
#define kNav ((AppDelegate *)[UIApplication sharedApplication].delegate.navigationController)
//拨打电话
#define canTel   ([[UIApplication sharedApplication]     canOpenURL:[NSURL URLWithString:@"tel:"]])
#define tel(phoneNumber)     ([[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel:%@",phoneNumber]]])
#define telprompt(phoneNumber) ([[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"telprompt:%@",phoneNumber]]])

//打开URL
#define canOpenURL(appScheme) ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:appScheme]])
#define openURL(appScheme) ([[UIApplication sharedApplication] openURL:[NSURL URLWithString:appScheme]])
