I made an iOS app that simply changes the background color when I tap the button. the goal is to change the color with Hopper. I successfully changed the color from blue to red but I cannot change from blue to green because the string "green" is bigger than "blue" so it's overlapping the next instruction:

So my question is what can I do ?

  • i don't know much about hopper, but I would try something like #00FF00 instead of colorgreen if that works

In practice you can't make your existing space any bigger.

Find another place in memory. You'd also need to update all the code referencing "blueColor" to use your new space address. One such candidate space could be strings describing segment and sections for __TEXT and __text respectively in the Mach-O header. Both of them will be exactly 16 bytes (padded with zeroes).
