I have an executable of a mac or ios app. This app uses a value stored for a key in NSUserDefaults to change app's flow.

It looks something like below code,

If( value set in user details )
        show something 
        hide something 

My question is how can I change the value stored for a key in NSUserDefaults using hopper disassembler ?

The values are stored in a plist file under ~/Library/Preferences (or ~/Library/Containers/.../ if sandboxed). You can find more information about it from Apple's documentation.

The easiest way to modify a value is to use the defaults program under terminal.

defaults write <bundle identifier> <key> <value>
