ios - 将OpenTok框架添加到我的项目中

Question

所以我试图将OpenTok框架添加到我的代码中。我要从https://tokbox.com/developer/sdks/ios/下载IOS SDK，然后将opentok.framwork文件拖到我的框架列表中。当我构建代码时，它会因以下错误而失败:

Answer 1

好的，问题有点复杂:
当您将库拖到项目中时，您弄乱了链接器的标志(可以在Build Phase-> Other Linker Flags中看到它们)，现在当cocoaPods成功添加OpenTok时(我尝试过，并且没有错误)仍然有标志(带有错误)。
现在是复杂的部分:真的很难知道哪个标志会引起问题。

(即使您删除了-Objc标志，该问题也可能来自其他标志，因为:
你得到一些继承，
您的项目可能需要此标志，
修改它们会导致其他错误
等)
，并且无法在xCode中“重置”您的标志。

因此最好的解决方案是:创建一个新项目，并用cocoapods OpenTok添加

platform :ios, '8.0'
use_frameworks!

target 'app' do
pod 'OpenTok', '~> 2.6'
end

target 'appTests' do
pod 'OpenTok', '~> 2.6'
end

target 'appUITests' do
pod 'OpenTok', '~> 2.6'
end

和我的过渡进口:

#import "OpenTok/OpenTok.h"

查看默认设置和cocoapod在新项目中是否仍然存在错误，如果没有，请在新项目中拖动之前的项目文件
