如何在我的應用程序控制器內使用相機

Question

如何在我的應用程序控制器內打開相機。

我不想介紹內置攝像頭控制器。
我想製作我自己的相機應用程序。

任何建議或指導將不勝感激。

您可以輕鬆地使用UIImagePickerController這個

1. 聲明UIImagePickerController *imagePickerController;全球該類
2. 聲明協議
   • @interface YourClassName : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate>

imagePickerController = [[UIImagePickerController alloc] init]; 
[imagePickerController setDelegate:self]; 
[imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera]; 
[imagePickerController setMediaTypes:@"public.image"]]; //specify image (not video) 
[imagePickerController setShowsCameraControls:NO]; //hide default camera controls 
[imagePickerController setNavigationBarHidden:YES]; 
[imagePickerController setToolbarHidden:YES]; 
[imagePickerController setAllowsEditing:NO]; 
[self.view addSubview:imagePickerController.view];

使用takePicture方法爲UIImagePickerController對象等，併爲其分配上的按鈕操作，比如：

-(IBAction)btnTakePictureAct:(UIButton *)sender 
{ 
    [imagePickerController takePicture]; 
} 

使用委託-imagePickerController:didFinishPickingMediaWithInfo:以獲取圖像。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    UIImage *image = info[UIImagePickerControllerOriginalImage]; 
}

看到這，拿個主意，讓您的自定義相機控制。
