帶有靜態庫（.a）和動態庫（.dylib）的重複符號

在我的iOS項目中，正在使用庫libbaidumapapi.a和libPayPalMPL.a。帶有靜態庫（.a）和動態庫（.dylib）的重複符號

該項目可以正確構建，但它在運行時發出異常信號。

在調試的問題，我發現它的原因是因爲庫libPayPalMPL.a調用庫內libbaidumapapi.a的XMLFreeDoc功能，但應該調用裏面xml2動態庫的xmlFreeDoc釋放功能。

我沒有這兩個庫的源代碼。當我檢查libbaidumapapi.a時，發現它與minixml.o和deflate.o存檔與XMLFreeDoc和deflate可能與libPayPalMPL.a衝突。

libPayPalMPL.a依賴於兩個動態庫的庫：xml2和zlib。

我可以修復這個崩潰問題嗎？我已在libbaidumapapi.a之前使用force_load。

以下是link命令，以防萬一需要。

MPL已被棄用。相反，建議您使用iOS SDK：https://github.com/paypal/PayPal-iOS-SDK

似乎PayPal-iOS-SDK僅適用於美國境內。我正在爲中國客戶開發一款應用程序。我看到PayPal-iOS-SDK也依賴於libxml2.dylib。我相信結果是一樣的。 https://developer.paypal.com/webapps/developer/docs/faq/ –
