iOS開發-iOS調用相機調用相簿【將圖片儲存到本地相簿】，ios-ios
設定頭部代理

<UINavigationControllerDelegate, UIImagePickerControllerDelegate>

1.調用相機

檢測自拍是否可用

- (BOOL)isFrontCameraAvailable{    return [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront];}

檢測後置網路攝影機是否可用

- (BOOL)isRearCameraAvailable{    return [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear];}

調用相機

///調用相機- (void)persentImagePicker{    if (!_imagePickerG) {        ///初始化相機        _imagePickerG = [[UIImagePickerController alloc]init];        ///代理        _imagePickerG.delegate = self;    }        // 前面的網路攝影機是否可用    if ([self isFrontCameraAvailable]) {        _imagePickerG.sourceType = UIImagePickerControllerSourceTypeCamera;    }    // 後面的網路攝影機是否可用    else if ([self isFirstResponder]){        _imagePickerG.sourceType = UIImagePickerControllerSourceTypeCamera;    }    else{        [SVProgressHUD showErrorWithStatus:@"沒有相機可用~"];        return;    }    ///允許拍照後裁剪    _imagePickerG.allowsEditing = YES;    [self.navigationController presentViewController:_imagePickerG animated:YES completion:nil];}

2.調用相簿

///調用本地相簿- (void)persentImagePicker{    if (!_imagePickerG) {        ///初始化相機        _imagePickerG = [[UIImagePickerController alloc]init];        ///代理        _imagePickerG.delegate = self;    }    ///相簿    _imagePickerG.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;    _imagePickerG.allowsEditing = YES;    [self.navigationController presentViewController:_imagePickerG animated:YES completion:nil];}

3.代理事件

///取消選擇圖片（拍照）- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{    [picker dismissViewControllerAnimated:YES completion:nil];}

///選擇圖片完成（從相簿或者拍照完成）- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];///原圖    //擷取修剪後的圖片    UIImage *imageUp = [info objectForKey:UIImagePickerControllerEditedImage];}

4.將圖片儲存到本地

///儲存圖片到本地相簿-(void)imageTopicSave:(UIImage *)image{    UIImageWriteToSavedPhotosAlbum(image, self, @selector(image: didFinishSavingWithError: contextInfo:), nil);}- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{    if (error == nil) {            }    else{        ///圖片未能儲存到本地    }}
