Create a method that will return a reversed string.

-(NSString *)reverseString:(NSString *)string{
    NSString *reverseString=[NSString new];
    for (NSInteger i=string.length-1; i>-1; i--) {
        reverseString=[reverseString stringByAppendingFormat:@"%c",[string characterAtIndex:i]];
    }
    return reverseString;
}

In your any of the method :

NSMutableArray *names=[NSMutableArray arrayWithObjects:@"anoop",@"johnson",@"wasim",nil];
for (NSInteger i=0; i<names.count; i++) {
    names[i]=[self reverseString:names[i]];
}
NSLog(@"%@",names);
