我收到一个错误说

 Error:Execution failed for task ':app:processDebugGoogleServices'.
    > Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 9.0.0.

我试着查看https://bintray.com/android/android-tools/com.google.gms.google-services/和com.google.gms:google-services:3.0.0似乎是最新的.这是我的项目

dependencies {
            classpath 'com.android.tools.build:gradle:2.1.2'
            classpath 'com.google.gms:google-services:3.0.0'
            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }

这就是我的应用程序gradle的样子

buildscript {
        repositories {
            maven { url 'https://maven.fabric.io/public' }
        }

        dependencies {

我想使用JSoup从HTML中选择具有特定文本的元素.html是

<td style="vertical-align:bottom;text-align:center;width:15%">
<div style="background-color:#FFDD93;font-size:10px;margin:5px auto 0px auto;text-align:left;" class="genbg"><span class="corners-top-subtab"><span></span></span>
    <div><b>Pantry/Catering</b>
        <div>
            <div style="color:#00700B;">&#10003;&nbsp;Pantry Car Avbl
                <br />&#10003;&nbsp;Catering Avbl</div>
        </div>
        <div>
            <div><span>Dinner is served after departure from NZM on 1st day.;</span>...
                <br /><a style="font-size:10px;color:Red;" onClick="expandPost($(this).parent());" href="javascript:void(0);">Read more...</a>
            </div>
            <div style="display:none;">Dinner :2 chapati, rice, dal and chicken curry (NV) and paneer curry in veg &amp;Ice cream.; Breakfast:2 bread slices with jam and butter. ; Omlet of 2 eggs (Non veg),vada and sambar(veg)..; coffee &amp; lime juice</div>
        </div>
    </div><span class="corners-bottom-subtab"><span></span></span>
</div>

我想找到包含文本"Pantry/Catering"的div元素.我试过了 …

我有以下代码将DatePicker添加到我的一个UIViews.

UIDatePicker *datePicker =
      [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 30, 320, 250)];
  [datePicker setDatePickerMode:UIDatePickerModeDate];
  datePicker.hidden = NO;
  datePicker.date = [NSDate date];
  [datePicker addTarget:self
                 action:@selector(changeDateInLabel:)
       forControlEvents:UIControlEventValueChanged];
  [self.dateView addSubview:datePicker];

这段代码已经存在了一段时间,但我们现在已经注意到一些随机崩溃了.崩溃只发生在iOS 11中.这就是崩溃的堆栈跟踪的样子

我需要帮助用我的手指找出精灵的旋转.精灵旋转很好,但是在我的手指初始触摸时,它会以某种方式单独旋转几度.

此外,旋转仅在手指围绕精灵中心旋转时才起作用.

我试图模拟自行车车轮,并有一个齿轮精灵和踏板精灵作为齿轮精灵的孩子.我希望自行车轮在我触摸踏板并旋转时旋转.我还没到那么远.现在我想弄清楚如何摆脱齿轮的初始换档.

这是完整的代码

@implementation BicycleScene

    CCScene *scene = [CCScene node];

我的代码中有以下几行,用于向UITextView添加可点击的URL.merchantwebsite是我的UITextView.

self.merchantwebsite.attributedText = [[NSAttributedString alloc] initWithString:@"http://www.crossfit.com" attributes:@{NSLinkAttributeName: @"http://www.crossfit.com"}];
self.merchantwebsite.userInteractionEnabled = YES;

当我单击UITextView时,应用程序会与日志崩溃

有人可以告诉我我做错了什么.

谢谢!

我们正在开发一款游戏,并且只想支持视网膜iPhone设备.我们为视网膜iPhone创建了@ 2x资产.游戏中有很多xib文件,我们将大量使用界面构建器.

如果我们直接在界面构建器中使用@ 2x资产,我们可以使用的唯一内容模式是"Scale to fill"或"Aspect Fill".在某些情况下,我们希望使用其他内容模式,如left,top.

我们可以想到的一个可能的解决方案是为非视网膜iPhone创建资产以及创建xib然后在进行最终构建之前移除非视网膜资产.

有没有人遇到过类似的问题.对此有更好的解决方法吗？
