如何检测我是否有iPhone 2G，3G，3GS

Question

如何通过iOS检测我当前的设备名称？

Answer 1

无论您使用的是iPhone还是iPod Touch：

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

要检测操作系统的版本：

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

要检测特定模型，您需要测试只有该模型具有的某些功能，以便检测iPhone 3GS，检查相机上的视频功能：

#define SOURCETYPE UIImagePickerControllerSourceTypeCamera

// does the device have a camera?
if ([UIImagePickerController isSourceTypeAvailable:SOURCETYPE]) {
  // if so, does that camera support video?
  NSArray *mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:SOURCETYPE];
  bool isA3GS = [mediaTypes containsObject:kUTTypeMovie];
}

Answer 2

这是Erica Sadun编写的一个类，它为此提供了广泛的功能：

查看其余的repo - 还有一些类可以证明对细粒度设备查询非常有用。

Answer 3

从UIDevice.h文件：

[[UIDevice currentDevice] name]              // e.g. "My iPhone"
[[UIDevice currentDevice] model]             // e.g. @"iPhone", @"iPod Touch"
[[UIDevice currentDevice] localizedModel]    // localized version of model
[[UIDevice currentDevice] systemName]        // e.g. @"iPhone OS"
[[UIDevice currentDevice] systemVersion]     // e.g. @"2.0"
[[UIDevice currentDevice] uniqueIdentifier]  // a string unique to each device based on various hardware info.

Answer 4

你在寻找的是：

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

这将返回设备是iPhone还是iPod touch
