The string in Objective-C programming dialect is spoken to utilizing NSString and its subclass NSMutableString gives a few approaches to making string articles. The most straightforward approach to make a string item is to utilize the Objective-C @"..." build:

NSString *greeting = @"Hello";

A straightforward sample for making and printing a string is demonstrated as follows.

#import <Foundation/Foundation.h>;
int main ()
{
NSString *greeting = @"Hello";
NSLog(@"Greeting message: %@\n", greeting );
return 0;
}

When the above code is compiled and executed, it produces result something as follows:

2013-09-11 01:21:39.922 demo[23926] Greeting message: Hello

Objective-C supports a wide range of methods for manipulate strings:

S.N.	Method & Purpose
1	- (NSString *)capitalizedString; Returns a capitalized representation of the receiver.
2	- (unichar)characterAtIndex:(NSUInteger)index; Returns the character at a given array position.
3	- (double)doubleValue; Returns the floating-point value of the receiver’s text as a double.
4	- (float)floatValue; Returns the floating-point value of the receiver’s text as a float.
5	- (BOOL)hasPrefix:(NSString *)aString; Returns a Boolean value that indicates whether a given string matches the beginning characters of the receiver.
6	- (BOOL)hasSuffix:(NSString *)aString; Returns a Boolean value that indicates whether a given string matches the ending characters of the receiver.
7	- (id)initWithFormat:(NSString *)format ...; Returns an NSString object initialized by using a given format string as a template into which the remaining argument values are substituted.
8	- (NSInteger)integerValue; Returns the NSInteger value of the receiver’s text.
9	- (BOOL)isEqualToString:(NSString *)aString; Returns a Boolean value that indicates whether a given string is equal to the receiver using a literal Unicode-based comparison.
10	- (NSUInteger)length; Returns the number of Unicode characters in the receiver.
11	- (NSString *)lowercaseString; Returns lowercased representation of the receiver.
12	- (NSRange)rangeOfString:(NSString *)aString; Finds and returns the range of the first occurrence of a given string within the receiver.
13	- (NSString *)stringByAppendingFormat:(NSString *)format ...; Returns a string made by appending to the receiver a string constructed from a given format string and the following arguments.
14	- (NSString *)stringByTrimmingCharactersInSet:(NSCharacterSet *)set; Returns a new string made by removing from both ends of the receiver characters contained in a given character set.
15	- (NSString *)substringFromIndex:(NSUInteger)anIndex ; Returns a new string containing the characters of the receiver from the one at a given index to the end.

Taking after case makes utilization of few of the aforementioned capacities:
