Xcode同一个项目多个target相互依赖的配置方法

e.g. we have 2 targets:

1. framework: MOJiAppStorePay
2. debug: DebugMOJiAppStore

if we want to use MOJiAppStorePay in DebugMOJiAppStore, we should config it as follows:

1. open DebugMOJiAppStore’s settings
2. under build settings, add MOJiAppStorePay as DebugMOJiAppStore’s dependency
3. under build settings, unfold Link Binary With Libraries, add MOJiAppStorePay and drag it after its own dependencies (MOJiBase.xc here)
