問題描述
我確信這有一個簡單的答案，但它難住了我:(
I'm sure this has got a simple answer, but it's stumping me :(
我正在嘗試構(gòu)建一個可以在 iOS 4.3 和 5.0 上運(yùn)行的應(yīng)用程序.我對在運(yùn)行時使用 -respondsToSelector 檢查功能的想法很好，但為了使用 Twitter 功能，我需要包含 Twitter 庫.
I'm trying to build an app that will run on iOS versions 4.3 and 5.0. I'm fine with the idea of checking for capabilities at runtime with -respondsToSelector, but in order to use the Twitter functionality I need to include the Twitter library.
這會導(dǎo)致編譯器在構(gòu)建 4.3 時失敗，這是我所期望的.根據(jù) Apple 文檔(在 this page)，可以有條件地鏈接框架 - 但我一生無法弄清楚如何設(shè)置其他鏈接器標(biāo)志來執(zhí)行此操作.誰能告訴我這是怎么做到的?
That causes the compiler to fail when building for 4.3, which I'd expect. According to the Apple docs (at the very bottom of this page), it's possible to link frameworks conditionally - but I cannot for the life of me figure out how to set the Other Linker flags to do this. Can anyone tell me how this is done?
推薦答案
在你的 Target -> Build Settings 中，搜索 Other Linker Flags 并點(diǎn)擊發(fā)布類型(Debug 或 Release)，然后在右下角點(diǎn)擊添加構(gòu)建設(shè)置 -> 添加條件設(shè)置，這將為您提供 SDK 彈出窗口以及指定任何其他標(biāo)志的能力.
In your Target -> Build Settings, search for Other Linker Flags and click on the type of release (Debug or Release) and then on the bottom right, click Add Build Setting -> Add Conditional Setting and that will give you the SDK popup and the ability to specify any additional flags.
