iOS添加framework, 报错“dyld: Library

背景

iOS项目的测试demo需要测试自己的的framework，叫IJKMediaFramework.framework。按如下方式导入后，运行起来报错。 

1. 将该framework放到工程下的某个文件下。 

2. 按照TARGETS->选择target->Build Phases->Link Binary With Libraries，添加该framework。

错误信息如下：

dyld: Library not loaded: @rpath/IJKMediaFramework.framework/IJKMediaFramework

 解决

在TARGETS->选择target->General-> Framework,Libraries,and Embedded Content下下，设置该Framework  Embed & sign。如下图:
