如何确定Mobile Safari崩溃的原因？ [英] How can I determine what crashed Mobile Safari?

问题描述

我的网站在Mobile Safari上崩溃，但在桌面上工作正常。

My website crashes on Mobile Safari, but works fine on desktop.

如何确定崩溃的原因？

推荐答案

Safari退出意外显示您的网站时可以执行的操作：

What you can do when Safari quits unexpectedly showing your website:

1。 Safari调试控制台

使用Safari的调试控制台。在iPhone中打开：设置 - > Safari->高级 - >调试控制台=打开。

Use Safari's debug console. Switch on in your iPhone: Settings->Safari->Advanced->Debug console=on.

对我说它

• 2行第6行的HTML错误 （无法识别键宽度的视口参数值device-width和无法识别键用户可缩放的视口参数值否。）


• 2 HTML提示也在第6行。

下次使用Safari检查网页时，将显示调试控制台。

Debug console will be shown next time you check your web page using Safari.

2。 Web Inspector（来自iOS 6.0）

如果在网页中发现问题变得越来越复杂，请使用Web Inspector调试Mobile Safari。 这是一个伟大的这个教程。

If it is getting more complicated to find out the problem in your webpage use Web Inspector to Debug Mobile Safari. It is a great tutorial for this.

使用IOS模拟器我发现对于这个特定的网站我所拥有的所有iOS版本，5.0,5.1和6.1，正确运行页面崩溃页面但在设备上（iOS 5.0.1）仍然崩溃。

Using IOS Simulator I found that for this particular website all iOS version I have, 5.0, 5.1 and also 6.1, runs the page correctly with crashing the page but on device (iOS 5.0.1) still crashes.

我的设备在iOS 5上运行，所以我无法访问Web Inspector，但肯定是下一步，您可以检查设备上的站点并检查计算机上的Web Inspector。

My device runs on iOS 5, so I cannot access Web Inspector, but it is certainly the next step for you to check your site on device and check Web Inspector on your machine.

3。使用iPhone配置实用程序的控制台

您可以下载Apple的 iPhone配置实用程序，然后您可以在Safari测试期间访问移动设备的控制台。

You can downlod Apple's iPhone Configuration Utility, then you can access your mobile's Console during Safari test.

检查您的网站我看到几个内存警告哪个最终导致Safari崩溃。

Checking your site I see couple of memory warnings which eventually lead to Safari crash.

4a。使用Xcode的调试工具

使用Xcode，您还可以访问设备的控制台（窗口 - >管理器 - >设备选项卡 - >控制台）。

Using Xcode you can also access the device's Console (Window->Organizer->Devices tab->Console).

您的案例在控制台上报告了以下内容：

Your case reported the following on console:

Apr 30 10:15:18 unknown kernel[0] <Debug>: launchd[2489] Builtin profile: MobileSafari (sandbox)   
Apr 30 10:15:38 unknown MobileSafari[2489] <Warning>: Received memory warning. 
Apr 30 10:15:39 unknown SpringBoard[15] <Warning>: Received memory warning.

4b。使用Xcode的调试工具，仪器

检查正在发生的事情的另一种复杂方法是​​使用仪器。

Another sophisticated way to check what's happening is to use Instruments.

再次检查您的站点我看到Safari在退出之前报告了许多低内存警告。遗憾的是，它并不能帮助您发现网站问题，但可能有助于查找Safari开放式错误报告。

Checking again your site I see many-many low memory warning reported by Safari before it quits. Sadly it doesn't directy help you discovering the web site problem but maybe helps to find Safari open bug reports.
