NSUserdefault

hii NSUserDefault is the default class provided to store some information by default. The storage is permanent storage  but stores a very little content as a dictionary. It uses a key value pairing concept.

 

the sample code to store the data in NSUserdefaults is

 

-(IBAction)savetouserdefaults:(id)sender

{

    

    

    

    NSUserDefaults *defaultsstorage=[NSUserDefaults standardUserDefaults];

//text1.text is the my textfiled1 data    

    [defaultsstorage setObject:text1.text forKey:@”name”];

    [defaultsstorage setObject:text2.text forKey:@”lastname”];

    

    [defaultsstorage synchronize];

    

 

}

 

 

// to retrieve the data from nsuserdegfaults

 

 

prints the associated data with the keys

 NSUserDefaults *defauls=[NSUserDefaults standardUserDefaults];

    

    NSLog(@”%@”,[defauls objectForKey:@”name”]);

    NSLog(@” lastname %@”,[defauls objectForKey:@”lastname”]);

– (void)viewDidLoad

{int num=10;

    

    

    for (int i=0; i<num; i++) {

    

        

        sub=[[UIView alloc]initWithFrame:CGRectMake(scrollview.frame.size.width*i, 0, scrollview.frame.size.width, scrollview.frame.size.height)];

        

        

        UILabel *lab=[[UILabel alloc]initWithFrame:CGRectMake(10, 200, 100, 100)];

        lab.text=@”scrollview”;

    

        UIImageView *imagev=[[UIImageView alloc]initWithFrame:CGRectMake(40, 40, 100, 100)];

        imagev.image=[UIImage imageNamed:@”info.png”];

        [sub addSubview:imagev];

        [scrollview addSubview:sub];

 

        

        

    }

    

    

    

    [scrollview setContentSize:CGSizeMake(scrollview.frame.size.width*num, scrollview.frame.size.height)];

    scrollview.delegate=self;

   // [scrollview addSubview:sub];

    [super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

Jail Breaking an iphone 4S

Jailbreak Using Absinthe

 

 

 

Step 1: Download Absinthe from here (Mac) or here (Windows), extract it, than run it.

Step 2: Connect your iPad 2 or iPhone 4S to your computer via USB.

Step 3: Click “Jailbreak” to run the program. The process takes awhile in the beginning so don’t worry! It will eventually say “Restoring in Progress,” leave the device alone until it’s completely finished.

Step 4: Once it’s done, you should see the Absinthe icon on the Home screen. Tap the icon and it will then take you to the Greenpois0n site and reboot your idevice. After it loads back up, the Cydia icon will have replaced the Absinthe icon.

And that’s all folks! You can than head over to Cydia and download all your favorite tweaks and apps!
