openFrameworks for iOS成爲Apple mach-O鏈接器錯誤

當我在openFrameworks for iOS中構建示例項目時，它變成了Apple mach-O Linker Error，但我對該項目沒有做任何事情。
無論我選擇哪個樣本項目，都會得到相同的結果。
我該如何解決？openFrameworks for iOS成爲Apple mach-O鏈接器錯誤

以下是整個錯誤信息。

你能粘貼鏈接器給你的問題的整個錯誤嗎？ – 2014-09-22 18:24:13

那會好嗎？ – 2014-09-22 18:38:32

至於第2至最後一行的錯誤信息表明，它看起來像你需要你的「部署目標」設定爲iOS 4.2或更高版本。看起來你正在嘗試爲iOS 3.1構建，但是一個庫使用的是需要4.2或更新版本的API。
