如何以编程方式区分iphone 4和iphone 4S？

分类: 技术问答 • 2022-06-22 00:13:46
问题描述：

我正在研究需要检查iPhone模型的应用程序，但我无法找到任何解决方案。我会非常感谢任何建议。如何以编程方式区分iphone 4和iphone 4S？

答

尝试使用以下：您将获得该设备的所有详细信息...

NSLog(@"uniqueIdentifier: %@", [[UIDevice currentDevice] uniqueIdentifier]); 
NSLog(@"name: %@", [[UIDevice currentDevice] name]); 
NSLog(@"systemName: %@", [[UIDevice currentDevice] systemName]); 
NSLog(@"systemVersion: %@", [[UIDevice currentDevice] systemVersion]); 
NSLog(@"model: %@", [[UIDevice currentDevice] model]); 
NSLog(@"localizedModel: %@", [[UIDevice currentDevice] localizedModel]);

如果上述方法不为你工作，然后使用github project

编辑：

无论你是在iPhone上还是在iPod Touch上：

UIDevice *device = [UIDevice currentDevice]; 
NSString *systemName = [device systemName];

为了检测OS的版本：

UIDevice *device = [UIDevice currentDevice]; 
NSString *systemVersion = [device systemVersion];

对于参考： how do I detect whether I have iPhone 2G,3G,3GS

不幸的是，这些都不会区分4和4S。 – chown

你有没有尝试github链接...这将肯定与众不同.... – DShah

谢谢DShah我已经通过了该项目，但它的旧版本我认为和[[UIDevice currentDevice]模型]只返回模型，而不是特定的模型类型（如iPhone4s，iphone4）。 – user1068810

这里是retriving设备模型的常用方法。有没有NS方法，所以你必须使用c

#include <sys/types.h> 
#include <sys/sysctl.h> 

- (NSString *)machine { 
    NSString *machine; 
    size_t size; 
    sysctlbyname("hw.machine", NULL, &size, NULL, 0); 
    char *name = malloc(size); 
    sysctlbyname("hw.machine", name, &size, NULL, 0); 
    machine = [NSString stringWithUTF8String:name]; 
    free(name); 
    return machine; 
}

这是一个公共API吗？ –

是的，只是包含sys/sysctl.h和sys/types.h – chown

太棒了，我会试试看。你们在哪里找到这个东西？ ;） –

这是更简单的。 很简单的只是COPY & PASTE

而且，我已经包括了机器名相匹配的型号名称。

为什么不只是返回一个emum？比字符串简单得多。 –

为了我的目的，我写了一个小型库，它抽象出底层的C调用并提供一个Objective-C接口。

NSLog(@"Big model number: %d", deviceDetails.bigModel); 
//Big model number: 4 

NSLog(@"Small model number: %d", deviceDetails.smallModel); 
//Small model number: 1 

if (deviceDetails.model == GBDeviceModeliPhone4S) { 
    NSLog(@"It's a 4S"); 
} 
//It's a 4S 

if (deviceDetails.family != GBDeviceFamilyiPad) { 
    NSLog(@"It's not an iPad"); 
} 
//It's not an iPad 

NSLog(@"systemInfo string: %@", [GBDeviceInfo rawSystemInfoString]); 
//systemInfo string: iPhone4,1

这是在GitHub上：GBDeviceInfo

这可能是输出：Device model: iPhone 4 GSM/ iPhone3,1

但是如果你是在模拟器上运行的应用程序，你将永远不会得到设备名称为“iPhone 6”“iPhone6 +”或类似的东西的。我目前使用的是Xcode Version 6.2 (6C131e)，其中我甚至在使用少量宏的模拟器上成功检查过设备类型。这些是

// ******************* DEVICE INDENTIFICATION MACROS *****************//
