UIImagePickerController拍照/相册/录像/本地视频

1.导入系统库

#import <MobileCoreServices/MobileCoreServices.h>

2.遵守协议

<UIImagePickerControllerDelegate,UINavigationControllerDelegate>

3.创建

#pragma mark 相机--拍照

- (void)openCamera{

    UIImagePickerController *ipc = [[UIImagePickerController alloc]init];

    ipc.sourceType = UIImagePickerControllerSourceTypeCamera;

    ipc.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage, nil];

    ipc.allowsEditing = YES;

    ipc.delegate = self;

    [self presentViewController:ipc animated:YES completion:nil];

    

    

}

#pragma mark 录像

- (void)openVideo{

    UIImagePickerController *ipc = [[UIImagePickerController alloc]init];

    ipc.sourceType = UIImagePickerControllerSourceTypeCamera;

    ipc.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeMovie, nil];

    ipc.videoQuality = UIImagePickerControllerQualityTypeHigh;

    ipc.allowsEditing = YES ;

    ipc.delegate = self;

    

    [self presentViewController:ipc animated:YES completion:nil];

    

}

 

 

#pragma mark  相册

- (void)openPhoto{

    UIImagePickerController *ipc = [[UIImagePickerController alloc]init];

    ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    ipc.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeImage, nil];

    ipc.allowsEditing = YES;

    ipc.delegate = self;

    [self presentViewController: ipc animated:YES completion:nil ];

    

}

#pragma mark  本地视频

- (void)openVideoList{

    UIImagePickerController *ipc = [[UIImagePickerController alloc]init];

    ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    ipc.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeMovie, nil];

    ipc.allowsEditing = YES;

    ipc.delegate = self;

    

    [self presentViewController:ipc animated:YES completion:nil];

    

}

 

 4.代理方法 

#pragma mark --Delegate 拍完后执行

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{

   

//判断是照片 or 视频

    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

    if ([mediaType isEqualToString:(NSString *)kUTTypeImage] && picker.sourceType == UIImagePickerControllerSourceTypeCamera ) {

       //图片

        UIImage *theImage = nil;

        //判断照片是否允许修改

        if ([picker allowsEditing]) {

            //获取编辑后的照片

            theImage = [info objectForKey:UIImagePickerControllerEditedImage];

        }else{

            theImage = [info objectForKey:UIImagePickerControllerOriginalImage];

        }

        //保存至相册

        UIImageWriteToSavedPhotosAlbum(theImage, self, nil, nil);

        

        

    }else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]){

        //视频

        //获取视频url

        NSURL *mediaUrl = [info objectForKey:UIImagePickerControllerMediaURL];

        //保存

        //方式一:

        //保存视频至相册

        NSString *urlPath = [mediaUrl path];

        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

            if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(urlPath)) {

                

                UISaveVideoAtPathToSavedPhotosAlbum(urlPath, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);

            }

        });

        

        //方式二:

        //创建 ALAssetLibrary对象,并保存到媒体看

//        ALAssetsLibrary *assetsLibray = [[ALAssetsLibrary alloc]init];

//        [assetsLibray writeVideoAtPathToSavedPhotosAlbum:mediaUrl completionBlock:^(NSURL *assetURL, NSError *error) {

//            if (!error) {

//                NSLog(@"保存成功");

//            }else{

//                NSLog(@"保存失败%@",error);

//            }

//            

//        }];

        

        

        

    }

    

   

    //隐藏

    [picker dismissViewControllerAnimated:YES completion:nil];

    

}

 

#pragma mark --Delegate 功能取消

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{

    

    [picker dismissViewControllerAnimated:YES completion:nil];

    

}
