String concat?

[nacho3d]

I'm sure that this was questioned thousand of times, and i did search on Google before posting this question.

But, my answer is, wich is the easiest way to concat strings.

For example, i have to build an url taking values of my app to pass as parameters in the url.

For example, the url that i have to request is:

http://myserver.com/myaction

and then i have to create something like this:

http://myserver.com/myaction?param1=...&param2=value2

taking those values from my app.

What i saw is something like this:

NSString *uri = @"http://myserver.com/myaction";
NSString *concatenate = [uri stringByAppendingString: @"?param1="];
NSString *concatenate1 = [concatenate stringByAppendingString: @"value1"];

But i really don't see it nice. Is there a nicer method to concat strings? Some operator like the one in java, in php, etc?

Not sure if it is the correct way however this is what I might do

NSString * uri = [NSString stringWithFormat:@"http://myserver.com/myaction?param1=%@param2%@", @"value1", @"value2"];

Something like that might work.

NSString objects are immutable. That means, once you've created them, they CANNOT be changed in any way.

The only way to keep a single object (as opposed to creating new objects each with a string appended onto the last) is to use an NSMutableString and its -appendString method:

NSMutableString *uri = @"http://myserver.com/myaction";
[uri appendString:@"?param1="];
[uri appendString:@"value1"];

Keep in mind though, that if you want to use a formatted string you will have to use appendFormat: instead of appendString:.

I believe you can join the elements of an array but I don't think there is a concat() function.
