直接上代码

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
        UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
        imagePickerController.delegate = self; //设置代理
        imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [navigationController presentViewController:imagePickerController animated:YES completion:nil];
    }
}

#pragma mark - UIImagePickerControllerDelegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:YES completion:^{}];
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; //通过key值获取到图片
    self.avatarView.image = image;
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    [picker dismissViewControllerAnimated:YES completion:^{}];
}

注意，弹出相册选择弹窗，不需要申请相册权限，只有将图片写入系统相册

才需要这个权限，并且，弹出系统相册弹窗的时候，要添加这个判断

if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
