常用宏定义和设备的判断

一、设备判断

真机与模拟器判断：
    #if defined(TARGET_IPHONE_SIMULATOR) && TARGET_IPHONE_SIMULATOR
        NSLog(@" on simulator");
    #else
        NSLog(@"not on simulator");
    #endif
    注意：TARGET_OS_IPHONE在真机和模拟器上都是1

    设备类型判断方法有两种：
    1. UI_USER_INTERFACE_IDIOM() 进行区分(ios 3.2以上)，但是无法区分iphone和ipod
        if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
            //设备为ipad
        } else {
            //设备为iphone 或 ipod
        }

或者

if([ [ UIDevice currentDevice ] userInterfaceIdiom ] == UIUserInterfaceIdiomPhone ){

    //IPhone设备

}else{

     //ipad设备

}
    2. 使用 UIDevice.model 进行区分  (ios 2.0 >=)
        NSString *deviceType = [UIDevice currentDevice].model;    
        if([deviceType isEqualToString:@"iPhone"]) {
              //iPhone
        }else if([deviceType isEqualToString:@"iPod touch"]) {
            //iPod Touch
        }else {
            //iPad
        }

或者

 if ([[UIDevice currentDevice].model rangeOfString:@"iPad"].location != NSNotFound) {

    NSLog(@"Thisis an iPad!");

}

不过网上有人说在使用第一种方法时发现，在Xcode4中，在项目的Summary页里必须将设备类型改为Universal才能生效。要不然就会一直返回为iPhone。所以，如果你的应用不需要设置成Universal，还是用第二种方法吧。

二、设备版本判断

1.

/*

 *  System Versioning Preprocessor Macros

 */

 

#define SYSTEM_VERSION_EQUAL_TO(v)                  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)

#define SYSTEM_VERSION_GREATER_THAN(v)              ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

#define SYSTEM_VERSION_LESS_THAN(v)                 ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)

#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v)     ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)

 

/*

 *  Usage

 */

 

if (SYSTEM_VERSION_LESS_THAN(@"4.0")) {

  

}

 

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"3.1.1")) {

 

}

2.

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 5.0) {
// iOS 5 code
for(UITabBarItem *tabBarItem in self.tabBar.items)

{
[tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIFont systemFontOfSize:14.0], UITextAttributeFont, nil]
forState:UIControlStateNormal];
}
}
else {
// iOS 4.x code
;
}

3.

#if __IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_6_0 // 当前支持的sdk版本是否低于6.0

 　　//ios 6.0以下的处理

#else

　　//ios 6.0以上的处理

 #endif

三、判断设备是否是iphone5，retina屏

1. #define isRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) : NO)  
2. #define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO)  

四、常用宏定义（.h）

30. #define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)  
31.   
32. //判断是真机还是模拟器  
33. #if TARGET_OS_IPHONE  
34. //iPhone Device  
35. #endif  
36.

102. 103. }  
103. 104. 
104. 107. #endif
105. 
     

五、设备信息

获取设备相关信息
    //软件信息
    NSLog(@"sysname=%@",[[UIDevice currentDevice] systemName]);// 系统名
    NSLog(@"systemVersion=%@",[[UIDevice currentDevice] systemVersion]); //版本号
    NSLog(@"model=%@",[[UIDevice currentDevice] model]); //类型（ipad、ipod、iphone）而[[UIDevice currentDevice] userInterfaceIdiom]只能判断iphone和ipad
    NSLog(@"olduuid=%@",[[UIDevice currentDevice] uniqueIdentifier]); //唯一识别码 ios5.0开始deprecated
    NSLog(@"name=%@",[[UIDevice currentDevice] name]); //设备名称
    NSLog(@"localizedModel=%@",[[UIDevice currentDevice] localizedModel]); // 本地模式
    NSLog(@"ios6UUID=%@",[[[UIDevice currentDevice] identifierForVendor] UUIDString]);//ios6.0开始available
    
   ----------注：以下内容未测试
    // 硬件信息
    [UIDevice platform];//平台
    [UIDevice cpuFrequency]];//cpu信息
    UIDevice busFrequency]];//总线
    [UIDevice totalMemory]];//总内存
    UIDevice userMemory]];//已经使用的内存
    
    //App信息
    NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
    CFShow(infoDictionary);//所有plist内容
    // app名称
    NSString *app_Name = [infoDictionary objectForKey:@"CFBundleDisplayName"];
    // app版本
    NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
    // app build版本
    NSString *app_build = [infoDictionary objectForKey:@"CFBundleVersion"];

    判断是否有照相机
    if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) 
        NSLog(@"有");
    else
        NSLog(@"没有");

六、判断设备

#import "sys/utsname.h"

    struct utsname systemInfo;

    uname(&systemInfo);

    NSString *deviceString = [NSStringstringWithCString:systemInfo.machineencoding:NSUTF8StringEncoding];

    if ([deviceStringisEqualToString:@"iPod2,1"])     return@"iPod Touch 2G";

    if ([deviceStringisEqualToString:@"iPod3,1"])     return@"iPod Touch 3G";

    if ([deviceString isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";

    if ([deviceString isEqualToString:@"iPod5,1"])      return @"iPod Touch 5G";

    if ([deviceString isEqualToString:@"iPad1,1"])      return @"iPad";

    if ([deviceString isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";

    if ([deviceString isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";

    if ([deviceString isEqualToString:@"iPad2,7"])     return@"iPad Mini (GSM+CDMA)";

    if ([deviceString isEqualToString:@"iPad3,1"])      return @"iPad 3 (WiFi)";

    if ([deviceString isEqualToString:@"iPad3,2"])      return @"iPad 3 (GSM+CDMA)";

    if ([deviceString isEqualToString:@"iPad3,3"])      return @"iPad 3 (GSM)";

    if ([deviceString isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";

    if ([deviceString isEqualToString:@"iPad3,5"])      return @"iPad 4 (GSM)";

    if ([deviceString isEqualToString:@"iPad3,6"])      return @"iPad 4 (GSM+CDMA)";

    if ([deviceString isEqualToString:@"iPad4,1"])      return @"iPad Air (WiFi)";

    if ([deviceString isEqualToString:@"i386"])         return @"Simulator";

    if ([deviceString isEqualToString:@"x86_64"])       return @"Simulator";
