ios - 如何检测我是否拥有 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];

要检测特定型号，您需要测试仅该型号具有的某些功能，因此要检测 iPhone 3GS，请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];
}

这是 Erica Sadun 编写的一个类，它为此提供了广泛的功能：

查看 repo 的其余部分 - 还有一些类将被证明对细粒度的设备查询非常有用。

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.

您正在寻找的是：

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

这将返回设备是 iPhone 还是 iPod touch
