Question

我正在使用UIImagepickerController从相机拍摄照片..我正在使用cameraoverlayview属性在相机视图上使用我自己的视图...我想在用户点击我的自定义视图中的按钮时从相机拍照...我正在使用以下代码

 - (void)viewDidLoad {

imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.sourceType =  UIImagePickerControllerSourceTypeCamera;
    [self presentModalViewController:imagePickerController animated:YES];   
    imagePickerController.showsCameraControls=NO;

imagePickerController.cameraOverlayView = self.customView;

}

- (IBAction) takePicture
{
    [imagePickerController takePicture];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

    imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

[picker dismissModalViewControllerAnimated:YES];

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    [self dismissModalViewControllerAnimated:YES];
}

但是当我运行此代码时，它会给我错误

错误：FigCreateCGImageFromJPEG返回-12905。输入（null）为773625字节。

我也会收到内存使用级别2和级别1

的警告

并且imageView中没有显示图像..谁能帮助我，我可能做错了什么？顺便说一句，我正在使用安装了iOS4.1的iPhone 3G

UIImagePickerControllerOriginalImage是一个符号（NSString *常量），你不能假设它的值。按原样使用，不带引号。除此之外，如果你正确地保留并创建了选择器和图像视图，它应该可以工作。

使用UIImagepickerController cameraoverlayview拍照？
