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];

}
