Question

我在我的iPhone应用程序中使用相机，当我在iPad2中打开此应用程序时，当我点击相机按钮时它会崩溃..

以下是我使用相机的代码

-(void) loadCamera{



UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];

    [imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
    [imagePickerController setDelegate:self];


    [imagePickerController setAllowsEditing:YES];
    [self presentModalViewController:imagePickerController animated:NO];
    [imagePickerController release];

}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo 
{

//      UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"" message:@"" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
//      [alert show];
//      [alert release];

        [picker dismissModalViewControllerAnimated:YES];

    //      // Access the uncropped image from info dictionary
        //  UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
            self.cameraimage.image=image;
            self.tinyImage.image=image;

        // Make the needed component visible
            self.cameraimage.hidden=NO;
            self.RemoveImage.hidden=NO;
            self.RetakePicture.hidden=NO;
            self.addphoto.hidden=YES;

            // Save image
            [constants saveImage:image withName:self.largeImageName];
            [constants saveImage:image withName:self.tinyImageName];
}

此代码在iPhone上运行良好但在iPad2上崩溃。

我的应用程序不适用于iPad .....而是在iPad上使用2x运行它

请帮忙。

您应该首先检查isSourceTypeAvailable：first

UIImagePickerControllerSourceType sourceType = UIImagePickerControllerSourceTypeCamera;
if([UIImagePickerController isSourceTypeAvailable:sourceType])
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.sourceType = sourceType;
    picker.delegate = self;
    if(sourceType == UIImagePickerControllerSourceTypeCamera)
        [picker takePicture];
    [self presentModalViewController:picker animated:YES];
    [picker release];
}

iPad2上的相机代码崩溃
