Weex编译后，Xcode工程项目编译报错–[UIView frame] must be used from main thread only

大致报错有以下两点。
1、Main Thread Checker: UI API called on a background thread: -[UIView frame]
PID: 10443, TID: 462862, Thread name: com.taobao.weex.bridge, Queue name: com.apple.root.default-qos.overcommit
2、Main Thread Checker: UI API called on a background thread: -[UIView subviews]

其中Weex库文件中，有两行报错。其中一行如下：
if (!(instance.rootView.subviews) || instance.rootView.subviews.count <=0) {

Xcode中，终端打印报错信息如下：

现象：
iOS项目在手机端运行，直接白屏。

问题查找：

步骤一：

在Weex项目中，执行weex run ios指令时候，终端中打印出如下信息：

  1. For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.6.0.beta.2
  3. Analyzing dependencies
  4. Downloading dependencies
  5. Using AMapFoundation (1.5.5)
  6. Using AMapLocation (2.6.1)
  7. Using SDWebImage (3.7.5)
  8. Using SocketRocket (0.4.2)
  9. Using WeexPluginLoader (0.0.1.9.1)
  10. Installing WeexSDK 0.19.0 (was 0.18.0.3)
  11. Generating Pods project
  12. Integrating client project
  13. Sending stats
  14. Pod installation complete! There are 5 dependencies from the Podfile and 6 total pods installed.
  15. ? Choose one of the following devices (Use arrow keys)

步骤二：

检查Xcode中Podfile 文件。如下：

  1. source 'git@github.com/CocoaPods/Specs.git'
  2. platform :ios, '8.0'
  3. #inhibit_all_warnings!
  5. def common
  6.     pod 'WeexSDK',
  7.     pod 'WeexPluginLoader'
  8.     pod 'SDWebImage', '3.7.5'
  9.     pod 'SocketRocket', '0.4.2'
  10.     pod 'AMapLocation' #定位SDK
  11. end
  13. target 'WeexDemo' do
  14.     common
  15. end
  17. target 'WeexUITestDemo' do
  18.     common
  19. end

发现，WeexSDK，并没有指定版本，但是在Weex项目编译过程中，出现过Installing WeexSDK 0.19.0 (was 0.18.0.3)，说明，这里直接将老的0.18.0.3版本升级到了0.19.0版本。

步骤三：

修改Xcode的Podfile文件，指定WeexSDK版本为0.18.0.3版本
修改后的Podfile文件如下：

  1. source 'git@github.com/CocoaPods/Specs.git'
  2. platform :ios, '8.0'
  3. #inhibit_all_warnings!
  5. def common
  6.     pod 'WeexSDK', '0.18.0.3'
  7.     pod 'WeexPluginLoader'
  8.     pod 'SDWebImage', '3.7.5'
  9.     pod 'SocketRocket', '0.4.2'
  10.     pod 'AMapLocation' #定位SDK
  11. end
  13. target 'WeexDemo' do
  14.     common
  15. end
  17. target 'WeexUITestDemo' do
  18.     common
  19. end

步骤四：

进入到Xcode项目根目录：
在终端中，输入指令pod install ,更新cocoapods相关库。
终端信息如下：

  1. ShiXiongweideMacBook-Pro:ios shixiongwei$ pwd
  2. /Users/shixiongwei/Documents/hctl/demo/blt4/blt-app-viewer/platforms/ios
  3. ShiXiongweideMacBook-Pro:ios shixiongwei$ pod install
  4. /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/universal-darwin17/rbconfig.rb:215: warning: Insecure world writable dir /Users/shixiongwei/ConfigDefine/SXWConfig/hadoop-3.1.1/bin in PATH, mode 040777

  25. Using WeexPluginLoader (0.0.1.9.1)
  26. Installing WeexSDK 0.18.0.3 (was 0.19.0)
  27. Generating Pods project
  28. Integrating client project
  29. Sending stats
  30. Pod installation complete! There are 5 dependencies from the Podfile and 6 total pods installed.

步骤五：

Xcode项目运行。不报错了。

后记：
本篇主要是记录遇到的问题，原理可能没讲出来，或者有其他错误的地方。反正这次是指定WeekSDK版本，重新编译后，就解决了。如有错误，敬请原理，同时，知道的，请告知，指正。谢谢。
