Question

I’ve concatenated string using the following code:

NSString *add = @"a ";
lbl.text = [add stringByAppendingString:lbl.text];

Which adds ‘a ‘ to lbl variable every time I call the function.

But for some reason this method concatenates in a way that the new string adds in the beginning of what’s already there, and not to the end.

Instead of getting AAABBB, I get BBBAAA. How do I fix this?

Answer 1

If a = AAA and b = BBB then you will need to write

[a stringByAppendingString:b];

So in your case it will be
[lbl.text stringByAppendingString:add]; as lbl.text = AAA and add = BBB.

For more information about this method please see NSString documentation.
