我正在使用http://www.sudzc.com/在我的 iPhone 应用程序中访问 SOAP Web 服务。我在 ASP.NET 中有一个方法，它接受一个字符串并返回一个字符串(准确地说是 facebook 访问 token )。
此字符串如下:
iOCCeM4WGIwBlDxECRFr4AfIEsW598Z4sYjk2uMxsyo.eyJpdiI6IkZPQlN1YWlGNXY0aWs3SmFMWFUwcVEifQ.ITh3ZBGrbgU8DsYWz6d-S4Q1iNlQ8DwKGZB6RZvOkTUpa0VmW7qFS6MO1tkauHoJMFrOlwSrvVuMEO_SQTh8xtR2d0219PPSshiYBHYkjsokSYTuyIaSclVIrL2vh7xH
我时不时地会在我的应用程序中收到如下错误，但我不太确定原因。实际字符串是我数据库中的一个 nvarchar(255) 字段。
此错误并非总是发生。但这样的事情已经发生过好几次了。
任何有关如何解决此问题的帮助将不胜感激。
提前致谢。

最佳答案
看起来我的 Web 服务已关闭，而且我根本没有在 Objective-C 中正确处理它。这就是为什么它返回 HTML(ASP.NET 错误页面)而不是字符串。
关于iPhone/Objective-C - 将字符串传递给方法时出现奇怪的错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5907651/
