如何创建带有全屏图像IOS定制的UIImagePickerController(How to cre

我有一个简单的UIImagePickerController它会用相机拍照，但也有几件事情，我想它做的事：

有一个自定义UI相机
以全屏幕而不是480×640（如果上4英寸的手机）

这里是我展示的UIImagePickerController的代码：

- (IBAction)pick:(id)sender {
    NSLog(@"abc");
    picker = [[UIImagePickerController alloc] init];
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        [picker setSourceType:UIImagePickerControllerSourceTypeCamera];
    } else {
        [picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
    }
    [picker setDelegate:self];
    [self presentViewController:picker animated:YES completion:nil];

}

这里是当图像被采取：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [self dismissViewControllerAnimated:YES completion:nil];
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
    [imageView setImage:image];
}

我该怎么做呢？

谢谢

对于第一点我想，你可以使用cameraOverlayView的财产UIImagePickerController对象在选择器默认界面添加自定义的用户界面：

- (IBAction)pick:(id)sender {
    NSLog(@"abc");
    picker = [[UIImagePickerController alloc] init];
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        [picker setSourceType:UIImagePickerControllerSourceTypeCamera];
    } else {
        [picker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
    }

    // Add here your custom UI here
    [picker setCameraOverlayView:self.customCameraOverlayView];

    [picker setDelegate:self];
    [self presentViewController:picker animated:YES completion:nil];

}

我测试过UIImagePickerController ，并与它的全尺寸（PixelXDimension和PixelYDimension）返回图像：

 UIImagePickerControllerMediaMetadata =     {
        DPIHeight = 72;
        DPIWidth = 72;
        Orientation = 6;
        "{Exif}" =         {
            ApertureValue = "2.526068811667588";
            BrightnessValue = "-0.5779073354035674";
            ColorSpace = 1;
            DateTimeDigitized = "2013:04:07 22:30:03";
            DateTimeOriginal = "2013:04:07 22:30:03";
            ExposureMode = 0;
            ExposureProgram = 2;
            ExposureTime = "0.05882352941176471";
            FNumber = "2.4";
            Flash = 24;
            FocalLenIn35mmFilm = 35;
            FocalLength = "4.28";
            ISOSpeedRatings =             (
                800
            );
            MeteringMode = 3;
            PixelXDimension = 3264;
            PixelYDimension = 2448;
            SceneType = 1;
            SensingMethod = 2;
            ShutterSpeedValue = "4.058893689053568";
            SubjectArea =             (
                1874,
                1478,
                610,
                612
            );
            WhiteBalance = 0;
        };
        "{TIFF}" =         {
            DateTime = "2013:04:07 22:30:03";
            Make = Apple;
            Model = "iPhone 4S";
            Software = "6.1.3";
            XResolution = 72;
            YResolution = 72;
        };
    };

你也可以设置为你的图像查看内容的方式来调整和适应容器视图：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [self dismissViewControllerAnimated:YES completion:nil];
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
    [imageView setContentMode:UIViewContentModeScaleAspectFill];
    [imageView setImage:image];
}

，之后以适合imageView ，因为你需要在你的视图控制器使用以在考虑设备屏幕（4英寸或没有） auto layout或auto sizing 。
