Question

My question is kind of general; in my project I have 10 UIButton objects
named Button1, Button2, Button3, Button4, Button5, Button6, Button7, Button8, Button9, and Button10

I also have UIImageview That are named exactly like the buttons from 1 to 10.

I want to write a code that will manipulate the image by the last character of the button (always a number from 1 to 10) and will affect the UIImageview the same way

Something like this

buttonlastcharacter = i;
    if(sender.lastcharacternumber is:i){
    Button%,i.frame = //Some manipulation

But basically all that I want is to have access to a certain object by string

How can I implement such a behavior?

Answer 1

It is maybe not the ideal solution in your case, but you can do it different ways:

using kvo

UIButton* myButton = [self valueForKey:[NSString stringWithFormat:@"button%i",i]];

or with selectors and properties

UIButton* myButton = [self performSelector:NSSelectorFromString([NSString stringWithFormat:@"button%i",i])];
