我有一个简单的喷雾客户端:

val pipeline = sendReceive ~> unmarshal[GoogleApiResult[Elevation]]

val responseFuture = pipeline {Get("http://maps.googleapis.com/maps/api/elevation/jsonlocations=27.988056,86.925278&sensor=false") }

responseFuture onComplete {
  case Success(GoogleApiResult(_, Elevation(_, elevation) :: _)) =>
    log.info("The elevation of Mt. Everest is: {} m", elevation)
    shutdown()

  case Failure(error) =>
    log.error(error, "Couldn't get elevation")
    shutdown()
}

完整代码可以在这里找到.

我想模拟服务器的响应来测试Success和Failure案例中的逻辑.我找到的唯一相关信息是在这里,但我无法使用蛋糕模式来模拟sendReceive方法.

任何建议或例子将不胜感激.

当用户在webview中滚动时,我正在尝试实现"消失"的URL栏.调用下面的函数- (void)scrollViewDidScroll:(UIScrollView *)scrollView.

对于特定的网页,该应用程序完全冻结并使用100%的CPU.从反复试验中我们得出结论,删除CGAffineTransformScale修复此问题.我试图理解为什么会发生这种情况以及我如何实现相同的功能.

- (void)collapseQueryBox
{

    _URLBarState = CLQURLBarStateCollapsing;
    _queryBoxViewHeightConstraint.constant = COLLAPSED_QUERYBOX_HEIGHT;

    [UIView animateWithDuration:COLLAPSE_ANIMATION_DURATION  animations:^{
        _webView.scrollView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);
        _queryLabel.transform = CGAffineTransformScale(_queryLabel.transform, COLLAPSE_ANIMATION_SCALE_FACTOR, COLLAPSE_ANIMATION_SCALE_FACTOR);
        _queryLabel.layer.backgroundColor = [UIColor clearColor].CGColor;
        [_browserContainerView layoutIfNeeded];
    } completion:^(BOOL finished) {
        _URLBarState = CLQURLBarStateCollapsed;
    }];
}

处于冻结状态的已暂停应用程序的完整堆栈跟踪:
