回答1:


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.

UIImagePickerController has a special method to determine whether a camera in available:

+ (BOOL)isSourceTypeAvailable:(UIImagePickerControllerSourceType)sourceType

With sourceType being one of

UIImagePickerControllerSourceTypePhotoLibrary,
UIImagePickerControllerSourceTypeCamera,
UIImagePickerControllerSourceTypeSavedPhotosAlbum



回答2:


NSString *deviceType = [UIDevice currentDevice].model;

if([deviceType isEqualToString:@"iPhone"])
{
     //your code
}
.....

Hope this helps.

EDIT:

See this thread -determine-device-iphone-ipod-touch-with-iphone-sdk .




回答3:


[[UIDevice currentDevice].model hasPrefix:@"iPhone"]

Use the "hasPrefix" so that it works in simulator.




回答4:


Make use of this to identify devices.

// 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

+ (BOOL)isSourceTypeAvailable:(UIImagePickerControllerSourceType)sourceType

Working on Vaibhav Tekam's answer, I used this

NSString *deviceType = [UIDevice currentDevice].model;


if([deviceType hasPrefix:@"iPhone"])
{
     //your code
}

or

 NSString *deviceType = [UIDevice currentDevice].model;

if([deviceType hasPrefix:@"iPad"])
{
     //your code
}

etc. It's much easier that way as it covers all models.
