Set symbol breakpoint on objc_msgSend then setup this debug command to log all methods called in iOS Simulator. If you want to do device debugging change esp+4 register to r0, esp+8 to r1 Found long ago somewhere on stackoverflow.
expr -- (void)printf("[%s, %s]\n",(char *) object_getClassName(*(long*)($esp+4)), (char *) *(long *)($esp+8) )

Add the current version and build number on your iOS app icon
#!/usr/bin/env ruby
# Requires ImageMagick: `brew install imagemagick`
# Requires version.sh from https://gist.github.com/osteslag/1089407
#
# Set RGM_STAMP_VERSION_ON_ICONS=1 in your build settings to enable/disable
# stamping on Debug/Relase configurations.
#
# Make base unstamped versions Icon.base.png, &c. in the source tree. The
# script will make stamped versions Icon.png, &c. It relies on Xcode to copy

steipete / PSPDFThreadSafeMutableDictionary.m
Last active January 20, 2025 07:33
Simple implementation of a thread safe mutable dictionary. In most cases, you want NSCache instead, but it can be useful in situations where you want to manually control what is evicted from the cache in low memory situations.**Warning:** I only use this for setting/getting keys. Enumeration is not thread safe here and will still throw exception…
