Simple String Combining

[thisma]

I want to put two strings together to form the name of the file passed to a UIImage. I think something like this:


NSMutableString *tempName = [NSMutableString stringWithString:@"foo"];
[tempStemName appendString:@"bar.png"];
imageOfStem = [UIImage imageNamed:tempName];


will work.

My question is: Is there some way of doing this more simply or without so much juggling; this solution seems very bloated.

I know I can't do this:


imageOfStem = [UIImage imageNamed:@"foo" + @"bar.png"];


But, something like:


imageOfStem = [UIImage imageNamed:[@"foo" returnStringWithStringAppended:@"bar.png"];


would be good.

trick here is @"foo" needs to remain @"foo"

Sorry to be such a n00b; I'm working on it. I did spend the prerequisite time Googling and found my self more confused afterward.

Please help,

Look at NSString +stringWithFormat.

FYI... use ... instead of <code> ... </code>

This will work:

imageOfStem = [UIImage imageNamed:[@"foo" stringByAppendingString:@"bar.png"]];
imageOfStem = [UIImage imageNamed:[NSString stringWithFormat:@"%@%@" @"foo", @"bar.png"]];

Working with immutable strings sometimes seems odd vs other languages that have a string concatenation operator.

interesting...

Thank you. I'll look at that more tomorrow.

:o also, thank you. :) I fixed it.

Awesome :D thank you. That's what I was looking for.
