问题
I just read this post about adding buttons with a loop programmatically.
I want to do the same thing, but do it with a name for each one, and animate them the same way. Is this a good idea, or should I just copy the same line of code for each button?
Further, I'd like to add a number of buttons (say four) from a list of names (greater than four) and pick them randomly. The catch is, I need them to be named properly and pull images associated with each name. Any ideas?
Thanks SO community!

As I see it, you should make a property list (.plist) with the array of buttons info - for each button there will be text to display, pic to display and action (method name or something).
You can generate four different random numbers in range [0, [buttonArray length]] and then generate your buttons in the loop for each selected number.
I guess, you need something like buttonFactory with method
-(UIButton*) makeButtonWithInfo(NSDictionary*)info
where name, picture adress, action etc. stored in info (you custom type buttonInfo if it is complicated).
Update:
Create new .plist in Xcode (resources/PropertyList) and fill it like this:
Read it in your code with
NSArray* buttonsArray = [NSArray arrayWithContentsOfFile:myPlist.plist];
There will be dictionaries with button info in this array.
Read in Xcode help about NSArray, NSDictionary and UIButton classes and implement your logic.
