Concatenate String in String Objective-c

6 Solutions Collect From Internet About “Concatenate String in String Objective-c”

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"
NSString * varyingString = ...;
NSString * cat = [NSString stringWithFormat:@"%s%@%@",
  "first part of string",
  @"third part of string"];

or simply -[NSString stringByAppendingString:]

Variations on a theme:

NSString *varying = @"whatever it is";
NSString *final = [NSString stringWithFormat:@"first part %@ third part", varying];

NSString *varying = @"whatever it is";
NSString *final = [[@"first part" stringByAppendingString:varying] stringByAppendingString:@"second part"];

NSMutableString *final = [NSMutableString stringWithString:@"first part"];
[final appendFormat:@"%@ third part", varying];

NSMutableString *final = [NSMutableString stringWithString:@"first part"];
[final appendString:varying];
[final appendString:@"third part"];

You would normally use -stringWithFormat here.

NSString *myString = [NSString stringWithFormat:@"%@%@%@", @"some text", stringVariable, @"some more text"];

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"

simple one:

[[@"first" stringByAppendingString:@"second"] stringByAppendingString:@"third"];

if you have many STRINGS to Concatenate, you should use NSMutableString for better performance
