}
- (IBAction)loadButton:(id)sender {

#end
Still not saving to the keys rejections and accepted
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:self.rejectLabel.text forKey:REJECTIONS];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:self.acceptedLabel.text forKey:ACCEPTED];
[[NSUserDefaults standardUserDefaults] synchronize];
NSLog(#"test save %# & %# & %# & %# pointers %# %#", REJECTIONS, ACCEPTED, self.rejectLabel.text, self.acceptedLabel.text, defaults, prefs);

Answer 1

It looks like you have muddled up your pointers. You have two references to the same instance of userDefaults yet you expect different results when writing to each one. Here, lets walk through your code
NSString *rejected=self.rejectLabel.text;
int reject=intToString(self.rejectLabel.text);
NSString *accepted=self.acceptedLabel.text;
NSUserDefaults *rejectTry=[NSUserDefaults standardUserDefaults];
Lets stop here. standardUserDefaults is a singleton object. You are not creating a user defaults object when you call this method. You then go on to set a value
[rejectTry setObject:self.rejectLabel.text forKey:REJECTIONS];
This works fine.
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:self.rejectLabel.text forKey:REJECTIONS];
Now you have written over your previous value!
[[NSUserDefaults standardUserDefaults] setValue:#"reject" forKey:REJECTIONS];
And you do it again!
[[NSUserDefaults standardUserDefaults] setValue:self.rejectLabel.text forKey:REJECTIONS];
[[NSUserDefaults standardUserDefaults] setObject:#"accepted" forKey:ACCEPTED];
Conclusion
What you should be doing is creating a local variable like this NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; Then use this for all your writes. Then you will see how you are overwriting the value with key REJECTIONS multiple times
