Iam amazed that none of the top answers pointed out that under recent Objective-C versions (after they added literals), you can concatenate just like this:

@"first" @"second"

And it will result in:

@"firstsecond"

You can not use it with NSString objects, only with literals, but it can be useful in some cases.

Just do  NSString  newString  NSString stringWithFormat   first part of string      third part of string     foo      This gives you     first part of string  foo  third part of string

You would normally use -stringWithFormat here   NSString  myString    NSString stringWithFormat              some text   stringVariable    some more text

simple one       first  stringByAppendingString   second   stringByAppendingString   third      if you have many STRINGS to Concatenate  you should use NSMutableString for better performance

Yes  do   NSString  str    NSString stringWithFormat    first part    second part   varyingString     For concatenation you can use stringByAppendingString  NSString  str     hello    str    str stringByAppendingString   world      str is now  hello world    For multiple strings  NSString  varyingString1     hello   NSString  varyingString2     world   NSString  str    NSString stringWithFormat            varyingString1  varyingString2     str is now  hello world
