Question

我使用下面的代码添加强制触摸预览操作... Peek和pop视图效果很好，只有动作没有显示...请帮助我的代码由于某种原因没有被执行，看看：

- (NSArray<id<UIPreviewActionItem>> *)previewActionItems {

    if (_previewActions == nil) {

        UIPreviewAction *rateAction = [UIPreviewAction actionWithTitle:@"Rate" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {

            EmbededRateViewController *embededRVC = [[EmbededRateViewController alloc]initWithEmployerToRate:self.employersArray[0]];

            embededRVC.view.bounds = CGRectMake(0, 0, self.view.frame.size.width - 40, 210);
            [embededRVC setPopinTransitionStyle:BKTPopinTransitionStyleSnap];

            BKTBlurParameters *blurParameters = [[BKTBlurParameters alloc] init];

            blurParameters.tintColor = [UIColor colorWithWhite:0 alpha:0.5];
            blurParameters.radius = 0.3f; // 0.3
            [embededRVC setBlurParameters:blurParameters];
            [embededRVC setPopinTransitionDirection:BKTPopinTransitionDirectionTop];
            [self.collectionView setScrollEnabled:NO];
            [self presentPopinController:embededRVC animated:YES completion:^{
                NSLog(@"Popin presented !");
            }];
        }];

        UIPreviewAction *commentAction = [UIPreviewAction actionWithTitle:@"Comment" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {

            NewCommentViewController *ncvc = [[NewCommentViewController alloc]initWithEmployer:self.employersArray[0]];
            [self presentViewController:ncvc animated:YES completion:nil];
        }];

        UIPreviewAction *reportAction = [UIPreviewAction actionWithTitle:@"Report" style:UIPreviewActionStyleDestructive handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {

            ReportEmployerViewController *reportEmpVC = [[ReportEmployerViewController alloc]initWithEmployer:self.employersArray[0]];
            [self presentViewController:reportEmpVC animated:YES completion:nil];
        }];

        UIPreviewAction *cancelAction =
        [UIPreviewAction actionWithTitle:@"Cancel"
                                   style:UIPreviewActionStyleSelected
                                 handler:^(UIPreviewAction *action,
                                           UIViewController *previewViewController){

                                 }];

        _previewActions = @[commentAction, rateAction, reportAction, cancelAction];
    }
    return _previewActions;

}

我面临同样的问题，被困了很久。

我犯的错误是在Caller View Controller中添加了这个方法。不要在调用者视图控制器中添加此方法，而是将其添加到被调用的视图控制器中。

例如，如果您在强制触摸View Controller A（调用者）时呈现View Controller B（调用），则将此方法添加到View Controller B（调用）。

并且太明显了，因为我们正在处理View控制器B中的按钮操作。

希望它对你有所帮助。祝一切顺利。

previewActionItems未被调用（强制触摸动作）
