is there an easier way to make something like this? - iphone

Question

like the Q
i have this code
K1player1D.text = [[NSUserDefaults standardUserDefaults] objectForKey:#"K1scoredLabel1"];
K1player1L.text = [[NSUserDefaults standardUserDefaults] objectForKey:#"K1scorelLabel1"];
K1player1K.text = [[NSUserDefaults standardUserDefaults] objectForKey:#"K1scorekLabel1"];
K1player1Q.text = [[NSUserDefaults standardUserDefaults] objectForKey:#"K1scoreqLabel1"];
K1player1T.text = [[NSUserDefaults standardUserDefaults] objectForKey:#"K1scoretLabel1"];
in viewDidLoad, for four players, so its 16 labels. is there any shorter way/code to do it ?

Answer 1

You could use NSMutableArray fill all the UILabel inside it and in a loop:
int i=1;
for(Player in ArrayOfUILabel){
Player.text = [[NSUserDefaults standardUserDefaults] objectForKey:(#"K1scoredLabel%d",i)];
i++;
}

Answer 2

EDIT
I would place them in an NSDictionary
NSDictionary * playerDict = [NSDictionary dictionaryWithObjectsAndKeys:
K1player1D,#"K1scoredLabel1",
K1player1L,#"K1scorelLabel1",
K1player1K,#"K1scorekLabel1",
K1player1Q,#"K1scoreqLabel1",
K1player1T,#"K1scoretLabel1",nil];
for(NSString * key in [playerDict allKeys]){
PlayerObject * player = [playerDict objectForKey:key];
player.text = [[NSUserDefaults standardUserDefaults] objectForKey:key];
}

Answer 3

There is another way to do this using Joels's answer combined with KVC (Key value coding). I don't know if it's a particularly good approach, but I've included it for the sake of completeness:
NSDictionary * playerDict = [NSDictionary dictionaryWithObjectsAndKeys:
#"K1player1D",#"K1scoredLabel1",
#"K1player1L",#"K1scorelLabel1",
#"K1player1K",#"K1scorekLabel1",
#"K1player1Q",#"K1scoreqLabel1",
#"K1player1T",#"K1scoretLabel1",nil];
for(NSString * key in [playerDict allKeys]){
NSString *labelName = [playerDict objectForKey:key];
UILabel *label = [self valueForKey:labelName]; // grab the correct label using KVC
label.text = [[NSUserDefaults standardUserDefaults] objectForKey:key];
}
This could be made simpler if the label names matched the keys in the NSUserDefaults (then you could just use an array of names instead of a dictionary).
