has been modified since the precompiled header

Clean工程
按住option键，再次Clean（Clean Build Folder...）
进入Window -> Organizer，在上面的Tab中选择Project，在左侧选中当前的工程，在右侧把Derived Data删除
报has been modified since the precompiled header错误的时候会显示很长的错误信息，其中有个包含DerivedData目录的路径，把路径指向的文件删掉
关闭Xcode，直接把 /Library/Developer/Xcode/ 目录删掉，然后启动Xcode自动重建此目录。如果你配置了自定义的快捷键，建议先把 /Users/你的用户名/Library/Developer /Xcode/UserData/KeyBindings 目录下你自定义的KeyBindings文件备份，之后再复制过来

如何解决…has been modified since the precompiled header… was built的问题

如何解决-has been modified since the precompiled header- was built 的问题 xcode5.1在程序中报错: File '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/System/Library/Frameworks/UIKit.framework/Hea

iOS 协同开发出fatal error: file ‘XX-Prefix.pch’ has been modified since the precompiled header was built

在协同开发的时候,刚刚从svn下载到本地的代码,出现“fatal error: file 'XX-Prefix.pch' has been modified since the precompiled header was built”的问题,这个其实不是什么问题,解决方案如下: 1.找到 XX-Prefix.pch 文件注释掉下面的代码: #ifdef __OBJC__ #import <UIKit/UIKit.h> #import <CoreData/CoreData.h>

解决 xx.h has been modified since the precompiled header 系统头文件被修改

fatal error: file '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIView.h' has been modified since the precompiled header '/Users/

xcode 编译错误 note: please rebuild precompiled header '/Users/wdl/Library/Developer/Xcode/DerivedData/ModuleCache/97F16MVNSP3M/UIKit-35TDUEIBFI6H.pcm'

在真机调试时遇到 atal error: file '/Applications/Xcode6.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIWebView.h' has been modified since the precompiled hea

fatal error C1853: 'Debug/***.pch' is not a precompiled header file created with this compiler

出现这个问题,把工程编译选项中的预编译去掉就可以了,操作步骤:首先全部重编译一下工程,如还是不行则试一试将工程设置中C/C++中precompiled header中选中automatic use of precompiled headers,并在相应through header中输入stdafx.h. 另外,rebuild all也是一种方法,或把debug目录下的文件删除,然后重新编译. fatal error C1853: 'Debug/***.pch' is no

skipped when looking for precompiled header

一般出现:warning C4627: '#include "../stdafx.h"': skipped when looking for precompiled header 这个错误时,只需在源文件开头加上 #include "stdafx.h"即可. 但有时候,源文件是放在与stdafx.h不同目录下的,直接按以上做法是不可行的.需要将stdafx.h的路径包含进项目工程里,在按上面的做法即可. 将stdafx.h所在路径添加进项目工程的方法如下: add

fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?

解决方法:设置cpp文件的Precompiled Header属性设置为Not Using Precompiled Headers fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source? 原文地址:https://www.cnblogs.com/MakeView66

添加头文件的报错failed to emit precompiled header 的解决办法

在buildsetting中的以下两个路径中添加对应的设置,重现编译即可解决,stackoverflow地址:点击 Solution:1 I added $(inherited) non-recursive to Search Path -> Header Search Paths2 Then added ${PODS_ROOT} recursive to Search Path -> User Header Search PathsBoth the above in my projects'

iOS遇到的问题：OC与swift混编造成的 Failed to emit precompiled header

当我接手一个OC与swift混编的项目的时候,其实我是拒绝的.哎,没有办法啊,只能干啦. pod完以后有很多问题,最难的问题就是这个了, 其实是由于他Podfile文件里面有use_frameworks!这样一句话,首先,我们先说一下他的作用. A.用cocoapods 导入swift 框架到 swift项目和OC项目都必须要 use_frameworks!B.使用 dynamic frameworks,必须要在Podfile文件中添加 use_frameworks! use_framewor
