Create in Objective-C

In Objective-C, a string can be created using the NSString class.

There are various ways to create a string in Objective-C, some common examples are:

1. Creating a string with a literal:

``objective-c NSString *myString = @"Hello World";



2. Using the stringWithFormat: method:

objective-c

   NSString *name = @"John";

   NSString *myString = [NSString stringWithFormat:@"Hello, %@!", name];

   NSLog(@"%@", myString); // outputs "Hello, John!"

   

3. Using the initWithFormat: method:
objective-c

   NSString *name = @"Mary";

   NSString *myString = [[NSString alloc] initWithFormat:@"Hello, %@!", name];

   NSLog(@"%@", myString); // outputs "Hello, Mary!"

   

4. Concatenating strings:
objective-c

   NSString *firstName = @"John";

   NSString *lastName = @"Doe";

   NSString *myString = [NSString stringWithFormat:@"%@ %@", firstName, lastName];

   NSLog(@"%@", myString); // outputs "John Doe"

   

5. Using a character array:
objective-c

   char cString[] = "Hello World";

   NSString *myString = [NSString stringWithCString:cString encoding:NSUTF8StringEncoding];

   NSLog(@"%@", myString); // outputs "Hello World"

Note that Objective-C also supports mutable strings, which can be modified after creation using the NSMutableString` class.
