Noorul Asan: Category - Sample Code for iPhone

1. Create a File for Objective - C Category and Click the Next Button

2. Type a Name for Category and Select the Category on NSString and Click the Create Button.

3. The File is created as Category Type. The File Name like as NSString+Name

4. Write the Below Codes

NSString+Name.h File

#import <Foundation/Foundation.h>

@interface NSString (Validate)

-(NSString *)checkthestring:(NSString *)string_value;

-(NSString *)checkanotherstring:(NSString *)str_value;

-(NSString *)nullcheck:(NSString *)string_null_value;

-(int)getLength:(NSString*)string_length;

@end

NSString+Name.m File

#import "NSString+Validate.h"

@implementation NSString (Validate)

-(NSString *)checkthestring:(NSString *)string_value
