标签：

　　1.添加代理UIImagePickerControllerDelegate

　　2.设置点击跳转事件

- (IBAction)picButton:(UIButton *)sender {

    NSLog(@"我的相册");

    if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]){

        //a.初始化相册拾取器

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

        //b.设置代理

        controller.delegate = self;

        //c.设置资源：

        /**

         UIImagePickerControllerSourceTypePhotoLibrary,相册

         UIImagePickerControllerSourceTypeCamera,相机

         UIImagePickerControllerSourceTypeSavedPhotosAlbum,照片库

         */

        controller.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

        //d.随便给他一个转场动画

        controller.modalTransitionStyle=UIModalTransitionStyleFlipHorizontal;

        [self presentViewController:controller animated:YES completion:NULL];

    }else{

        UIAlertView * alert = [[UIAlertView alloc]initWithTitle:@"提示" message:@"设备不支持访问相册，请在设置->隐私->照片中进行设置！" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];

        [alert show];

    }

}

　　3.获取图片

#pragma mark-> imagePickerController delegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

{

    //a.获取选择的图片

    UIImage *image = info[UIImagePickerControllerOriginalImage];

    self.imageView.image = image;

}
