来源：互联网发布：通信达交易软件编辑：程序博客网时间：2024/05/17 13:08

创建UIImagePickerController对象定以属性

@property(nonatomic, strong)UIImagePickerController *imagePickerController; //选择相册//设置相册- (void)setpImagePicker{    _imagePickerController = [[UIImagePickerController alloc] init];    _imagePickerController.delegate = self;    _imagePickerController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;    _imagePickerController.allowsEditing = YES;}

设置获取图片的来源 , 如相机，或者相册，以下代码是直接从相册选择在你的单击事件中调用此方法

#pragma mark  ----- 从相册获取图片- (void)selectImageFromAlbum{    _imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;    [self presentViewController:_imagePickerController animated:YES completion:nil];}

实现UIImagePickerControllerDelegate, UINavigationControllerDelegate代理方法

#pragma mark ------- 选择图片后的代理方法- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {        //如果是图片        UIImage *image = info[UIImagePickerControllerEditedImage];    }     [self dismissViewControllerAnimated:YES completion:nil];}
