ios UIImagePickerController簡單說明

標籤：

首先，VC中添加#import <MobileCoreServices/MobileCoreServices.h> 使用(NSString *) kUTTypeImage定義在其中

判斷是否授權：

 NSString *mediaType = AVMediaTypeVideo;// Or AVMediaTypeAudioAVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:mediaType];

    AVAuthorizationStatusNotDetermined = 0,//未明確
    AVAuthorizationStatusRestricted,//受限
    AVAuthorizationStatusDenied,//不允許
    AVAuthorizationStatusAuthorized//允許

第一種使方法照相機:

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
//添加代理imagePicker.delegate = self;
//是否允許編輯imagePicker.allowsEditing = YES;
//資源類型imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
//media類型imagePicker.mediaTypes =  [[NSArray alloc] initWithObjects: (NSString *) kUTTypeImage, nil];
//轉跳[self presentModalViewController:imagePicker animated:YES];

第二種使用攝像機：

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; imagePicker.allowsEditing = YES;imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
//media類型imagePicker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
//視頻品質imagePicker.videoQuality = UIImagePickerControllerQualityTypeLow;[self presentModalViewController:imagePicker animated:YES];

第三種使用相簿取圖片類型：

 UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];imagePicker.delegate = self; imagePicker.allowsEditing = YES; imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; imagePicker.mediaTypes =  [[NSArray alloc] initWithObjects: (NSString *)kUTTypeImage, nil]; [self presentModalViewController:imagePicker animated:YES];

第四種使用相簿取視頻類型：

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];imagePicker.delegate = self;imagePicker.allowsEditing = YES;imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; imagePicker.mediaTypes =  [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];[self presentModalViewController:imagePicker animated:YES];

代理：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{　　if ([[info objectForKey:UIImagePickerControllerMediaType] isEqualToString:(NSString*)kUTTypeImage]) {
　　　　　　//擷取照片的原圖        UIImage* original = [info objectForKey:UIImagePickerControllerOriginalImage];        //擷取圖片裁剪的圖        UIImage* edit = [info objectForKey:UIImagePickerControllerEditedImage];        //擷取圖片裁剪後，剩下的圖        UIImage* crop = [info objectForKey:UIImagePickerControllerCropRect];        //擷取圖片的url        NSURL* url = [info objectForKey:UIImagePickerControllerMediaURL];        //擷取圖片的metadata資料資訊        NSDictionary* metadata = [info objectForKey:UIImagePickerControllerMediaMetadata];        //如果是拍照的照片，則需要手動儲存到本地，系統不會自動儲存拍照成功後的照片       // UIImageWriteToSavedPhotosAlbum(edit, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
　　} else if ([[info objectForKey:UIImagePickerControllerMediaType] isEqualToString:(NSString*)kUTTypeMovie]) {　　　　NSString *videoPath = [[info objectForKey:UIImagePickerControllerMediaURL] path];　　　　self.fileData = [NSData dataWithContentsOfFile:videoPath]; 
　　}　　[picker dismissModalViewControllerAnimated:YES];}- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {     [picker dismissModalViewControllerAnimated:YES];}
