How would I save and load a UITextField?

Question

I have searched everywhere and tried lots of code but nothing seems to be working for me. All I need to do is to load (on viewDidLoad) a text field and save it when a button is

Create a NSMutableDictionary as property and ...

when your button is clicked:

-(IBAction)buttonClicked:(id)sender
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];   
NSString *devicePath = [documentsDirectory stringByAppendingPathComponent:@"yourfile.txt"]; 
[self.dictionary setObject:self.textField.Text key:@"textField"];
[self.dictionary writeToFile:devicePath atomically:YES];
}

On your viewDidLoad, you can get the value of the file by:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"youefile"
                                                     ofType:@"txt"];
self.dictioary = [[[NSMutableDictionary alloc] initWithContentsOfFile:filePath] autorelease];
