NSInvalidArgumentException’, reason: ‘Cannot create an NSPersistentStoreCoordinator with a nil model’

问题描述：NSInvalidArgumentException', reason: 'Cannot create an NSPersistentStoreCoordinator with a nil model'
问题解决：原因是缺少.momd文件，即缺少.xcdatamodeld文件，在工程中加上就行

SSH into iPhone over USB without Wi-Fi

最近在做iPhone守护进程，通过ssh和scp等脚本安装，速度总是不理想。同事告知如下可以通过usb运行ssh，找到如下好东西，附上安装运行方法。

1.准备python环境并下载usbmuxd
2.把手机通过USB连接Mac
3.运行python usbmuxd-1.0.8/python-client/tcprelay.py -t 22:2222
4.运行ssh root@localhost -p2222

这里有一篇for windows的：http://www.securitylearn.net/2012/10/11/ssh-into-iphone-over-usb-without-wi-fi/

CocoaPods错误

问题描述：用“pod update”更新，遇到如下错误

Pull is not possible because you have unmerged files.

Please, fix them up in the work tree, and then use 'git add/rm <file>'

as appropriate to mark resolution, or use 'git commit -a'.

问题解决：

A bug was found in libgit2 and they had to execute a force push on the specs repo. This is what broke everyone's CocoaPods setup.

You can find the official post about this issue on the CocoaPods blog :http://blog.cocoapods.org/Repairing-Our-Broken-Specs-Repository/

The recommended way to fix your setup is to execute the following commands :

$ pod repo remove master
$ pod setup

If that doesn't work, you can also delete manually all your cached specs :

$ rm -rf ~/.cocoapods/
$ pod setup

Xcode创建动态库

1.用Xcode打开如下2个xcspec文件：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Specifications/iPhoneOSPackageTypes.xcspec
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Xcode/Specifications/MacOSX Package Types.xcspec

2.把MacOSX Package Types.xcspec中Identifier为com.apple.package-type.mach-o-dylib的item复制到iPhoneOSPackageTypes.xcspec

3.把MacOSX Product Types.xcspec中Identifier为com.apple.product-type.library.dynamic的item复制到iPhoneOSProductTypes.xcspec

以上为真机，模拟器类似，路径在：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/Xcode/Specifications/

 

1.把/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/Project Templates/Framework & Library/Cocoa Touch Static Library.xctemplate整个文件夹复制并改名为Cocoa Touch Dynamic Library.xctemplate

2.修改Description中的"a static library"为"a dynamic library"
修改Identifier中的"cocoaTouchStaticLibrary"为"cocoaTouchDynamicLibrary"
修改Description中的".static"为".dynamic"

 

1.Installation Directory设置为@executable_path/
