How do I load data using NSEntityDescription? - iphone

Question

i am new in xcode. i hope someone will teach me more xcode.
i'm learning core data now, from what i learn, i can save my data from uitextfield using uibutton. this is my code.
- (IBAction)button1:(id)sender
{
TestSaveDataAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
NSManagedObjectContext *context = [appDelegate managedObjectContext];
Highscore *record = [NSEntityDescription insertNewObjectForEntityForName:#"Highscore" inManagedObjectContext:context];
record.highscore1 = textField.text;
NSLog(#"Saved for %#", textField.text);
NSError *error;
if (![context save:&error])
{
NSLog(#"Error");
}
now i have a UILabel call label and a button2 next to it. how do i load my data in my label when button2 is pushed? Please teach me.
i already wrote like this but i dont know how to put it in my label. any tutorial that i find only put it in tableview. i don't want to put it in tableview, i just want my data show in my label.
- (IBAction)button2:(id)sender
{
TestSaveDataAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
NSManagedObjectContext *context = [appDelegate managedObjectContext];
NSFetchRequest *request = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"Highscore" inManagedObjectContext:context];
[request setEntity:entity];
NSError *error;
if (![context save:&error])
{
NSLog(#"Error");
}
}

You have to add NSPredicate to your request and execute it.
NSPredicate *predicate = <#create your predicate here#>;
[request setPredicate:predicate];
NSError *error;
NSArray *results = [context executeFetchRequest:request error:&error];
if (error) {
//inform user
}
//if you found something, you can set text for your UILabel
if ([results count]) {
Highscore *record = [results objectAtIndex:0];
label.text = record.highscore1;
}
