我在互联网上搜索了解决方案，但不幸的是我无法找到解决问题的方法。

大多数人都在创建UIImagePickerController类的对象，但我决定以不同的方式来做这件事。

我创建了一个新类CameraViewController，这个类扩展了UIImagePickerController.

我的 .h 文件：

#import <UIKit/UIKit.h>

@interface CameraViewController : UIImagePickerController <UIImagePickerControllerDelegate>

-(void)captureImage;

@end

我的 .m 文件：

#import "CameraViewController.h"

#define CAMERA_TRANSFORM_X 1
#define CAMERA_TRANSFORM_Y 1.5

@interface CameraViewController ()

@end

@implementation CameraViewController 

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 568)];
    UIButton *btnCapture = [[UIButton alloc] initWithFrame:CGRectMake((320/2)-(76/2), 480, 76, 76)];
    [btnCapture setImage:[UIImage imageNamed:@"cam.png"] forState:UIControlStateNormal];
    [btnCapture addTarget:self  action:@selector(captureImage) forControlEvents:UIControlEventTouchUpInside];

    [view addSubview:btnCapture];

    self.sourceType = UIImagePickerControllerSourceTypeCamera;

    self.showsCameraControls = NO;
    self.navigationBarHidden = YES;
    self.wantsFullScreenLayout = YES;
    self.cameraViewTransform = CGAffineTransformScale(self.cameraViewTransform, CAMERA_TRANSFORM_X, CAMERA_TRANSFORM_Y);
    self.cameraOverlayView = view;
    //[self openCamera];
    // Do any additional setup after loading the view.
}

-(void)takePicture //overwrite take picture method
{
    [super takePicture];
    NSLog(@"%@", self);

}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSLog(@"%@", info);
}

-(void)captureImage
{
    [self takePicture];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

我实现了 delegate UIImagePickerControllerDelegate。但似乎imagePickerController由于某种原因没有调用 my 。在这种方法中，我尝试记录一个NSDirectory. 所以我想也许我可以通过覆盖该takePicture方法来获得我的图像，但我不知道如何。有谁知道如何帮助我？非常感谢

来自苹果文档The UIImagePickerController class supports portrait mode only. This class is intended to be used as-is and does not support subclassing.

所以你不能子类化UIImagePickerController。
