Question

I have two viewcontrollers. In my first viewcontroller:

{           
    NSString *string=textField.text;  
    NSUserDefaults *data = [NSUserDefaults standardUserDefaults];  

    [data setObject:string forKey:@"strings"];
    [data synchronize];
}   

How do I get the string value in my other viewcontroller?

Here you can use this in anyway in your application for store value of NSUserDefaults.

// --- Saving

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
// saving an NSString
[prefs setObject:@"TextToSave" forKey:@"keyToLookupString"];  
// saving an NSInteger
[prefs setInteger:42 forKey:@"integerKey"];
// saving a Double
[prefs setDouble:3.1415 forKey:@"doubleKey"];
// saving a Float
[prefs setFloat:1.2345678 forKey:@"floatKey"];
// This is suggested to synch prefs, but is not needed (I didn't put it in my tut)
[prefs synchronize];

Here you can use this in anyway in your application for get value of NSUserDefaults.

// --- Retrieving

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
// getting an NSString
NSString *myString = [prefs stringForKey:@"keyToLookupString"];
// getting an NSInteger
NSInteger myInt = [prefs integerForKey:@"integerKey"];
// getting an Float
float myFloat = [prefs floatForKey:@"floatKey"];
