A collection of scripts I wrote that have something to do with iOS.

Unless otherwise noted, all scripts are bash scripts and will require bash to run.

Unless otherwise noted at the top of a file itself, all files in this repository were written by me and are placed in the public domain.

There are also a few things I use that are too short for their own scripts, but I find wicked useful.
I placed these in my ~/.profile, either as alias or as variable assignments.

Never type the SDK path again:

iSDK='/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk';

Compile for iOS with igcc:

alias igcc='xcrun -sdk iphoneos gcc -Wall -arch armv7 -arch arm64';

Self-sign a binary with entitlements, using isign ent.plist binary:

isign()
{
    codesign -s - --entitlements "$2" "$1";
}

Dump any ASN.1 file in DER format (e.g. every img4 file ever) with asn1dump:

alias asn1dump='openssl asn1parse -i -inform DER -in';

I find it annoying to get my phone's local WLAN IP every time I connect to it, and I find it annoying to enter a password every time.
Here's how to get rid of both of these:

• Install libusbmuxd to get iproxy.
• Add the public key of your PC to /var/mobile/.ssh/authorized_keys on your phone.
• Add this entry to ~/.ssh/config on your PC:

Host iphone
    HostName 127.0.0.1
    Port 2222
    User mobile
    StrictHostKeyChecking no
    UserKnownHostsFile /dev/null

Now

• Plug in your phone over USB.
• Run iproxy 2222 22 and leave it open.
• In a new tab/window, run ssh iphone.

If done right, it won't ask for a password ever again¹.

¹ Except if the device was rebooted and has not yet been unlocked for the first time, because at that point /var/mobile/.ssh/authorized_keys is still encrypted and not readable.
