iOS App 开发问题汇总（二）

1.Ad Hoc分发应用

导出Ad Hoc授权应用 Xcode > Product > Archive > Export

安装Ad Hoc分发的应用 Open iTunes > File > Add To Library… > select Ad Hoc provisioning profile and App.ipa > Sync

2.Xcode编译出现如下警告提示：

[WARN]warning: no rule to process file xxx.h’ of type sourcecode.c.h for architecture armv7

解决办法:这是因为检查到有.h文件在编译列表中了。所以只要在列表中去掉就可以了。

点击你的xcode项目文件，然后点击[Build Phases]，确保在[Compile Sources]中没有.h文件。

Reference:Xcode编译提示：warning: no rule to process file ‘xxx.h’ of type sourcecode.c.h for architecture armv7

3.ld: warning: directory not found for option ‘-L/Users/dongmeiliang/Documents/soh.client.iOS/sohiOSApp/sohiOSApp/Component/BaiduMap_IOSSDK_v2-2/Release-iphonesimulator’

Undefined symbols for architecture x86_64: “DDExtractFileNameWithoutExtension”, referenced from: 57-[AJSocketBinaryClientChannel setupReadTimerWithTimeout:]block_invoke76 in libPods-sohiOSApp-AJFrame.iOS.a(AJSocketBinaryClientChannel.o) -[AJSocketBinaryClientChannel doReadTimeout] in libPods-sohiOSApp-AJFrame.iOS.a(AJSocketBinaryClientChannel.o) -[AJSocketBinaryClientChannel endCurrentRead] in libPods-sohiOSApp-AJFrame.iOS.a(AJSocketBinaryClientChannel.o) “OBJC_CLASS$DDLog”, referenced from: objc-class-ref in libPods-sohiOSApp-AJFrame.iOS.a(AJSocketBinaryClientChannel.o) “OBJC_CLASS$_GCDAsyncSocket”, referenced from: objc-class-ref in libPods-sohiOSApp-AJFrame.iOS.a(AJTcpConnector.o) ld: symbol(s) not found for architecture x86_64

解决办法：从输出的日志可以看出问题是出在链接，由Cocoapods管理的第三方库安装后链接配置项没有设置正确，需要手动设置没有被自动链接的库，例如这里我需要链接：-l"Pods-CocoaAsyncSocket"。

4.dyld: could not load inserted library ‘/usr/lib/libgmalloc.dylib’ because image not found

解决办法：Edit Scheme > Run > Diagnostics > Memory Managerment

Malloc uncheck Enable Scribble
uncheck Enable Guard Edges
uncheck Enable Guard Malloc

Reference:xcode : could not load inserted library: /usr/lib/libgmalloc.dylib 的解决

5.APNs服务器地址

答案： gateway.push.apple.com 2195 (Product)
gateway.sandbox.push.apple.com 2195 (Development)

6./Users/user/XCodeWork/iPhoneDev/MyAppSourceFolder/en.lproj/MainWindow-iPhone.xib:

Compilation failed. Unable to write to path:
/Users/user/Library/Developer/Xcode/DerivedData/MYAPPNAME- dudnhxzgpqtcnqcgaguirvkhmvco/Build/Intermediates/ArchiveIntermediates/ MYAPPNAME/InstallationBuildProductsLocation/Applications/MyAppname.app/ en.lproj/MainWindow-iPhone.nib

解决办法：For every xib’s that we’ve problems, in the right panel go to the first tab, “Interface Builder Document” -> “Builds for” and select “iOS 7.0 and Later”. My old configuration was “iOS 4.3 and Later”.

7.duplicate symbol OBJC_METACLASS$_SDWebImagePrefetcher in:

/Users/dongmeiliang/Library/Developer/Xcode/DerivedData/jiaxiaotong-dxrmnnwbexugoqfekesgvdiijcdm/Build/Products/Debug-iphonesimulator/libPods-weima-SDWebImage.a(SDWebImagePrefetcher.o)
/Users/dongmeiliang/Library/Developer/Xcode/DerivedData/jiaxiaotong-dxrmnnwbexugoqfekesgvdiijcdm/Build/Products/Debug-iphonesimulator/libPods-SDWebImage.a(SDWebImagePrefetcher.o)

ld: 727 duplicate symbols for architecture x86_64

解决办法：问题出现的原因是我用CocoaPods管理第三方库，在Build Settings > Linking > Other Linker Flags 里面即显示指定了-l"Pods-SDWebImagePrefetcher",又设置了变量$(inherited)。我去掉$(inherited)就好。

9.Cannot send push notifications using Javapns/Javaapns SSL handshake failure

解决办法：

developer_identity.cer <= download from Apple (aps cert)
mykey.p12 <= Your private key (CSR generate private key or install aps cert get a private key both ok)

openssl x509 -in developer_identity.cer -inform DER -out developer_identity.pem -outform PEM
openssl pkcs12 -nocerts -in mykey.p12 -out mykey.pem
openssl pkcs12 -export -inkey mykey.pem -in developer_identity.pem -out iphone_dev.p12

Reference:Cannot send push notifications using Javapns/Javaapns SSL handshake failure

10.导航栏如何显示两行文本？

解决办法：After setting up your titleView or titleLabel, call sizeToFit on it, also make sure titleLabel.textAlignment = UITextAlignmentCenter. It’ll be centered in the width of the navbar rather than in the space between the button edge and far edge of navbar.

Reference:Adjusting navigationItem.titleView’s frame?

11.SVN how to resolve “local unversioned, incoming add upon update”

$ svn status
D     C logs
      >   local unversioned, incoming add upon update
Summary of conflicts:
  Tree conflicts: 1

解决办法:

$ svn resolve --accept working logs
Resolved conflicted state of 'logs'
$ svn revert logs
Reverted 'logs'
$ svn status

Reference:Resolve Tree Conflict SVN (local unversioned, incoming add upon update)

12.Calling a C function from within a function in a .mm file

解决办法：The .mm file is looking to call a mangled version of the function name. You need either BEGIN_DECLS and END_DECLS around the C function declarations seen by the C++-compiled file, or you need to do the equivalent yourself. The idea is to mark those function declarations as extern “C” when seen by an (Obj-)C++ compiler, but not when seen by any other sort of compiler.

13.Compilation failed. Unable to write to path

Underlying Errors:
    Description: The file “objects.nib” doesn’t exist.
    Failure Reason: The file doesn’t exist.
    Underlying Errors:
        Description: The operation couldn’t be completed. No such file or directory

    Failure Reason: The file doesn’t exist.
    Underlying Errors:
        Description: The operation couldn’t be completed. No such file or directory
        Failure Reason: No such file or directory

解决办法：在Target > Build Phases > Compile Sources里去掉出错的nib文件。
