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

声明:本文转载自:狮兄

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

Main Thread Checker: UI API called on a background thread: -[UIView frame]

PID: 998, TID: 202842, Thread name: com.taobao.weex.bridge, Queue name: com.apple.root.default-qos.overcommit, QoS: 21

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:

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

Analyzing dependencies

Downloading dependencies

Using AMapFoundation (1.5.5)

Using AMapLocation (2.6.1)

Using SDWebImage (3.7.5)

Pod installation complete! There are 5 dependencies from the Podfile and 6 total pods installed.

? Choose one of the following devices (Use arrow keys)


步骤二:

检查Xcode中Podfile 文件。如下:

source '[email protected]/CocoaPods/Specs.git'

platform :ios, '8.0'

#inhibit_all_warnings!

def common

pod 'WeexSDK',

    pod 'WeexPluginLoader'

    pod 'SDWebImage', '3.7.5'

    pod 'SocketRocket', '0.4.2'

    pod 'AMapLocation' #定位SDK

end

target 'WeexDemo' do

    common

end

target 'WeexUITestDemo' do

    common

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:

source '[email protected]/CocoaPods/Specs.git'

platform :ios, '8.0'

#inhibit_all_warnings!

def common

pod 'WeexSDK', '0.18.0.3'

    pod 'WeexPluginLoader'

    pod 'SDWebImage', '3.7.5'

    pod 'SocketRocket', '0.4.2'

    pod 'AMapLocation' #定位SDK

end

target 'WeexDemo' do

    common

end

target 'WeexUITestDemo' do

    common

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:
