Answer 1

Save:

[[NSUserDefaults standardUserDefaults] setValue:_email forKey:@"email"];
[[NSUserDefaults standardUserDefaults] setValue:_password forKey:@"password"];
[[NSUserDefaults standardUserDefaults] synchronize];

For reading:

_email = [[NSUserDefaults standardUserDefaults] stringForKey:@"email"];
_password = [[NSUserDefaults standardUserDefaults] stringForKey:@"password"];

In your case:

[[NSUserDefaults standardUserDefaults] setValue:Number.text forKey:@"Number"];

and

NSString * number = [[NSUserDefaults standardUserDefaults] stringForKey:@"Number"];

A “key” is usually hardcoded and acts like a “variable name” for things in storage (typical name and value pairs, such as a dictionary).

Check if the value is set or not; after reading it:

if (number) ...
