Setting value in nsuserdefaults

I'm new to Objective-C and XCode and I've encountered such a problem.

How do you properly save the value to NSUserDefaults.

I have value in 

[_textFields objectAtIndex:2]).text

And trying to do this 

[[[NSUserDefaults standardUserDefaults] setValue:((UITextField *)[_textFields objectAtIndex:2]).text))  forKey:@"Phone"];
[[NSUserDefaults standardUserDefaults] synchronize];

How do you do it properly?

Use method setObject:forKey: instead of setValue:forKey:

In NSUserDefaults class:

[[NSUserDefaults standardUserDefaults] setObject:"Your Object" forKey:@"Phone"];

You are working with strings values. You should use setObjectForKey (save) and objectForKey (read). Here's an example

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
NSString *yourText = [[_textFields objectAtIndex:2] text]; // Your text

// Save
[userDefaults setObject:yourText forKey:kKey];
[userDefaults synchronize];

// Read
NSString *result = (NSString *) [userDefaults objectForKey:kKey];

Use setObject:forKey: instead of setValue:forKey:

[[[NSUserDefaults standardUserDefaults] setObject:((UITextField *)[_textFields objectAtIndex:2]).text)) forKey:@"Phone"];

Update: You code will work if you really have that text field in the array. Here is the step by step broken down code to make it more clear:

UITextField* textField = [_textFields objectAtIndex:2]; // get your text field
NSString* text = textField.text; // get the actual value we are going to store
[[[NSUserDefaults standardUserDefaults] setObject:text forKey:@"Phone"]; // store it

You need to use the setObject:forKey: if you want to store property list objects (dictionaries, arrays, strings and numbers) in NSUserDefaults. See the docs.
