[[UIDevice currentDevice].model hasPrefix:@"iPhone"]
Use the "hasPrefix" so that it works in simulator.
使用“hasPrefix”使其在模拟器中工作。

You should not determine whether there is a camera by looking at the model. This is not future proof - for instance, you would not be supporting the iPad 2's camera.
您不应通过查看模型来确定是否有摄像头。这不是未来的证明 - 例如，您将不支持 iPad 2 的相机。
UIImagePickerController has a special method to determine whether a camera in available:
UIImagePickerController 有一个特殊的方法来判断一个摄像头是否可用：
+ (BOOL)isSourceTypeAvailable:(UIImagePickerControllerSourceType)sourceType
With sourceType being one of
sourceType 是其中之一
UIImagePickerControllerSourceTypePhotoLibrary,
UIImagePickerControllerSourceTypeCamera,
UIImagePickerControllerSourceTypeSavedPhotosAlbum

Make use of this to identify devices.
利用它来识别设备。
// If iPhoneOS is 3.2 or greater then __IPHONE_3_2 will be defined
#ifndef __IPHONE_3_2
typedef enum {
UIUserInterfaceIdiomPhone, // iPhone and iPod touch
UIUserInterfaceIdiomPad, // iPad
} UIUserInterfaceIdiom;
#define UI_USER_INTERFACE_IDIOM() UIUserInterfaceIdiomPhone
#endif // ifndef __IPHONE_3_2
but if you want to check if camera is available I think you can make use of UIImagePickerController's static method
但是如果你想检查相机是否可用，我认为你可以使用 UIImagePickerController 的静态方法
+ (BOOL)isSourceTypeAvailable:(UIImagePickerControllerSourceType)sourceType

Working on Vaibhav Tekam's answer, I used this
处理 Vaibhav Tekam 的答案，我使用了这个
NSString *deviceType = [UIDevice currentDevice].model;
if([deviceType hasPrefix:@"iPhone"])
{
//your code
}
or
或者
NSString *deviceType = [UIDevice currentDevice].model;
if([deviceType hasPrefix:@"iPad"])
{
//your code
}
etc. It's much easier that way as it covers all models.
等等。因为它涵盖了所有模型，所以这样更容易。
