我是一位新的IOS開發人員。我試圖在Xcode中創建許多iOS項目，但都顯示了Build Failed錯誤。用HelloWorld，我可以得到它與AutoLayout有關 - 我沒有選擇，就是這樣。IOS：Building Fails
有了這個其他項目，我找不出錯誤的原因。的錯誤是：` 構建目標CorporateChat

我得到這樣的5個錯誤與SBJasonStreamWriterAccumelator.m，SBJasonStreamParserAccumelator.m，SBJasonStreamParseState.m，SBJasonWriter.m和我的實現類之一。我剛剛添加了SBJason到項目中，沒有實現任何功能。
任何人都可以請幫助我讓我的項目建立成功。從開始，我只能看到Build Failed。我的座右銘是我希望應用程序能夠在大多數平臺上執行 - 我計劃支持從4到最新的7個。我是否缺失或需要任何項目設置中的更正！
是否需要做任何設置更改或導致此錯誤的原因。請幫幫我。
謝謝
嘗試清理該項目並再次運行。 –
「NSObject.h已被修改...」。這很討厭，應該永遠不會發生，除非你最近改變了Xcode版本，在這種情況下，乾淨的應該把它整理出來。 – trojanfoe
