[转载]Developing without Provisioning Profile

| 分类 文档  | 标签 iOS  编程 

To develop for the devices one should first obtain a provisioning profile by joining the iPhone Developer Program (which costs $99). However, some simple tricks can be used to make Xcode compile and debug on jailbroken devices without provisioning profiles.

These steps are only tested for Xcode 3.2.x/iPhone SDK 3.x and Xcode 4.3.x/iPhone SDK 5.x. If for some reason you are stuck with Xcode 3.1.x, try [1].

Compiling

Performing these steps allows you to use Xcode to compile any applications and deploy it yourself.

  • 1. Create a self-signed code-signing certificate with the name “iPhone Developer” on the “login” (default) keychain using Keychain Access[1].

  • 2. Open /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Info.plist (4.2 or below: /Developer/Platforms/iPhoneOS.platform/Info.plist)

  • 3. Replace all occurrences of XCiPhoneOSCodeSignContext by XCCodeSignContext. There are three of them (XCode Version 3.2.4+).

  • 4. Save the file and restart Xcode.

If you upgrade the iPhone SDK, you need to perform steps 2 – 4 again.

Replacing codesign with ldid

These steps are necessary for debugging, since the entitlement can no longer be inserted by performing steps 1 – 4. To actually debug your app, make sure you have add -gta to Other Code Signing Flags of your target.

  • 5. Make sure you have ldid on your Mac[2]. Place a copy in /usr/local/bin.

  • 6. Create the Python script /usr/local/bin/ldid3.py. Make it executable. Fill it with:

    #!/usr/bin/env python

    from sys import argv from subprocess import check_call from os.path import basename, splitext, join from tempfile import NamedTemporaryFile

    app = argv[-1] obj_path = join(app, splitext(basename(app))[0])

    if ‘-gta’ not in argv: check_call([‘/usr/local/bin/ldid’, ‘-S’, obj_path]) else: with NamedTemporaryFile() as f: f.write(“”” <!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”>

    get-task-allow 
        """)
    check_call(['/usr/local/bin/ldid', '-S' + f.name, obj_path])

  • 7. Open iPhoneCodeSign.xcspec.

    • For Xcode 4.3 the file is at: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/PrivatePlugIns/iPhoneOS Build System Support.xcplugin/Contents/Resources/iPhoneCodeSign.xcspec

    • For Xcode 4.2 the file is at: /Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/PrivatePlugIns/iPhoneOS Build System Support.xcplugin/Contents/Resources/iPhoneCodeSign.xcspec

    • For older versions the file is at: /Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Plug-ins/iPhoneOS Build System Support.xcplugin/Contents/Resources/iPhoneCodeSign.xcspec

  • 8. Replace the line saying CommandLine = “/usr/bin/codesign” with CommandLine = “/usr/local/bin/ldid3.py”. It should be around line 12.

  • 9. Save the file and restart Xcode.

If you upgrade the iPhone SDK, you need to perform steps 8 – 9 again.

Allowing apps with invalid signatures to be installed

These steps allow you to install an unsigned app to the device. This method only works for iOS 4.0 or above.

  • 10. Create a file /var/mobile/tdmtanf on the device, to enable Apple’s “TDMTANF bypass” in installd (warning: doing so will also put you in a sandboxed GameCenter[3]).

If you upgrade the firmware, you need to do step 10 again.
