How to save content of TextField to plist

I want to save the content of TextFields in plist with corresponding Key-Values pair. Like Password field should be saved with the Key-Password and Value-(entered in textField).

How can I do that?

and want to access it in some other class. Can I do it? If yes, then how?

Best practice would be saving these info in NSUserDefaults instead of a plist. NSUserDefautls can be accessed from anywhere in your project.

Saving:

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setObject:[yourTextfield text] forKey:@"password"];

Retrieving:

 NSString *myPassword = [[NSUserDefaults standardUserDefaults] objectForKey:@"password"];

 NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

NSString *aFilePath = [NSString stringWithFormat:@"%@/plistName.plist", aDocumentsDirectory];

NSMutableArray *plistArray = [[NSMutableArray alloc] initWithContentsOfFile:aFilePath];


NSMutableDictionary *newComment = [NSMutableDictionary dictionary];
[newComment setValue:userName.text forKey:@"username"];
[newComment setValue:password.text forKey:@"password"];


[plistArray addObject:newComment];
[plistArray writeToFile:filePath atomically:YES];

Adding Stuff into plist is easy. Full working code follows which adds a persons contact info into a plist -

// get paths from root direcory
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
// get documents path
NSString *documentsPath = [paths objectAtIndex:0];
// get the path to our Data/plist file
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"Data.plist"];

// set the variables to the values in the text fields
self.personName = nameEntered.text;
self.phoneNumbers = [[NSMutableArray alloc] initWithCapacity:3];
[phoneNumbers addObject:homePhone.text];
[phoneNumbers addObject:workPhone.text];
[phoneNumbers addObject:cellPhone.text];

// create dictionary with values in UITextFields
NSDictionary *plistDict = [NSDictionary dictionaryWithObjects: [NSArray arrayWithObjects: personName, phoneNumbers, nil] forKeys:[NSArray arrayWithObjects: @"Name", @"Phones", nil]];

NSString *error = nil;
// create NSData from dictionary
NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:plistDict format:NSPropertyListXMLFormat_v1_0 errorDescription:&error];

// check is plistData exists
if(plistData) 
{
    // write plistData to our Data.plist file
    [plistData writeToFile:plistPath atomically:YES];
}
else
{
    NSLog(@"Error in saveData: %@", error);
    [error release];
}

Yes, Take a NSMutableDictionary add values of UITextFeild property of text in in keys of Dictionary. Like

         NSMutableDicitonary * dictionary = [[NSMutableDictionary alloc] init];
        [dictionary setObject:textfield.text forKey:@"username"];
        [dictionary setObject:textfield.text forKey:@"password"];

Save Dictionary in plist and use it where ever it requires.

You can save the content of textField to Plist in the following manner : 

        NSMutableDictionary *_plistDict = [NSMutableDictionary dictionaryWithContentsOfFile:pListPath];
        [_plistDict setValue:textField.text forKey:@"Password"];
        [_plistDict writeToFile:pListPath atomically:YES];

If you want to retrieve that value from pList , You can use the following code : 

NSMutableDictionary *_plistDict = [NSMutableDictionary dictionaryWithContentsOfFile:pListPath];
    NSString *status = [NSString stringWithFormat:@"%@",[_plistDict objectForKey:@"Password"]];
