objective-c - 在 iOS5 中实现库时获取 "apple mach-o linker id error undefined symbols for architecture i386"

Question

我在 XCode 4 中实现 PayPal 库时遇到了问题。当我尝试构建项目时出现此错误:

Undefined symbols for architecture i386:
"_xmlParseMemory", referenced from:
-[AdaptivePaymentsSOAP11Binding_CancelPreapproval connectionDidFinishLoading:] in libPayPalMPL.a(AdaptivePayments.o)
-[AdaptivePaymentsSOAP11Binding_ConfirmPreapproval connectionDidFinishLoading:] in libPayPalMPL.a(AdaptivePayments.o)
-[AdaptivePaymentsSOAP11Binding_ConvertCurrency connectionDidFinishLoading:] in libPayPalMPL.a(AdaptivePayments.o)
-[AdaptivePaymentsSOAP11Binding_ExecutePayment connectionDidFinishLoading:] in libPayPalMPL.a(AdaptivePayments.o)
-[AdaptivePaymentsSOAP11Binding_GetPaymentOptions connectionDidFinishLoading:] in libPayPalMPL.a(AdaptivePayments.o)
-[AdaptivePaymentsSOAP11Binding_PaymentDetails connectionDidFinishLoading:] in libPayPalMPL.a(AdaptivePayments.o)
-[AdaptivePaymentsSOAP11Binding_Pay connectionDidFinishLoading:] in libPayPalMPL.a(AdaptivePayments.o)
...

在网络上搜索我发现这是从 XC3 传递到 XC4 时的典型错误。也许图书馆没有更新。但是您在那里看到的那个文件 .a 似乎是不可编辑的。

已解决。必须加载 3 个框架:libXML、Security 和 libz。
