Setting a Row as Selected Based off of NSUserDefaults Value? - ios

Question

I'm currently working on a view where a player can choose a character to play with. I have a tableView where each row represents a character. Inside each row is a button that a player taps to select that respective character. The first time a user loads it, only one character is available (first row) and I do the following in viewDidLoad:
//If not selected character exists set it to the default character
if (![[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"]) {
[[NSUserDefaults standardUserDefaults] setInteger:0 forKey:#"Current Character"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
NSLog(#"Value: %d", [[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"]);
By default all of the buttons in each row are hidden revealing a lock image behind it. So I do the following in the cellForRowAtIndexPath method:
//CHECK FOR UNLOCKED ITEMS
switch (indexPath.row) {
case 0: {
//Always show since it will always be available
cell.playerButton.hidden = NO;
break;
}
case 1: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item2Unlocked"]) {
cell.playerButton.hidden = NO;
} else {
cell.playerButton.hidden = YES;
}
break;
}
case 2: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item3Unlocked"]) {
cell.playerButton.hidden = NO;
} else {
cell.playerButton.hidden = YES;
}
break;
}
case 3: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item4Unlocked"]) {
cell.playerButton.hidden = NO;
} else {
cell.playerButton.hidden = YES;
}
break;
}
default:
break;
}
Everything is working great so far. The problem that I'm facing is figuring out how to update the button in the correct row to a selected state. I've tried doing the following, but it ends up updating more than one button:
//CHECK FOR UNLOCKED ITEMS
switch (indexPath.row) {
case 0: {
cell.playerButton.hidden = NO;
if ([[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"] == 0) {
cell.playerButton.selected = YES;
} else {
cell.playerButton.selected = NO;
}
break;
}
case 1: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item1Unlocked"]) {
cell.playerButton.hidden = NO;
if ([[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"] == 1) {
cell.playerButton.selected = YES;
} else {
cell.playerButton.selected = NO;
}
} else {
cell.playerButton.hidden = YES;
}
break;
}
case 2: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item2Unlocked"]) {
cell.playerButton.hidden = NO;
if ([[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"] == 2) {
cell.playerButton.selected = YES;
} else {
cell.playerButton.selected = NO;
}
} else {
cell.playerButton.hidden = YES;
}
break;
}
case 3: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item3Unlocked"]) {
cell.playerButton.hidden = NO;
if ([[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"] == 3) {
cell.playerButton.selected = YES;
} else {
cell.playerButton.selected = NO;
}
} else {
cell.playerButton.hidden = YES;
}
break;
}
default:
break;
}
What's wrong here?
UPDATE
Doing the following, the selected state finally worked:
//CHECK FOR UNLOCKED ITEMS
switch (indexPath.row) {
case 0: {
cell.playerButton.hidden = NO;
if ([[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"] == 0) {
cell.playerButton.selected = YES;
NSLog(#"Character is selected.");
} else {
cell.playerButton.selected = NO;
}
break;
}
case 1: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item1Unlocked"]) {
cell.playerButton.hidden = NO;
if ([[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"] == 1) {
cell.playerButton.selected = YES;
NSLog(#"Character B is selected.");
} else {
cell.playerButton.selected = NO;
}
} else {
cell.playerButton.hidden = YES;
}
break;
}
case 2: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item3Unlocked"]) {
cell.playerButton.hidden = NO;
if ([[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"] == 2) {
cell.playerButton.selected = YES;
NSLog(#"character C is selected.");
} else {
cell.playerButton.selected = NO;
}
} else {
cell.playerButton.hidden = YES;
}
break;
}
case 3: {
if([[NSUserDefaults standardUserDefaults] boolForKey:#"item4Unlocked"]) {
cell.playerButton.hidden = NO;
if ([[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"] == 3) {
cell.playerButton.selected = YES;
NSLog(#"Character D is selected.");
} else {
cell.playerButton.selected = NO;
}
} else {
cell.playerButton.hidden = YES;
}
break;
}
default:
break;
}
However how can I disable the button or user interaction if button is selected?

This should do the same thing and is a lot simpler
//CHECK FOR UNLOCKED ITEMS
int currentCharacter=[[NSUserDefaults standardUserDefaults] integerForKey:#"Current Character"];
BOOL unlocked=NO;
if (indexPath.row == 0)
{
unlocked=YES; // Character 0 is always unlocked
}
else {
unlocked=[NSUserDefaults standardUserDefaults] boolForKey:[NSString stringWithFormat:"%#item%dUnlocked",indexPath.row]]
}
if (unlocked)
{
cell.playerButton.hidden=NO;
if (indexPath.row == currentCharacter)
{
cell.playerButton.selected=YES;
cell.playerButton.enabled=NO; //Cannot select if already selected
}
else
{
cell.playerButton.selected=NO;
cell.playerButton.enabled=YES;
}
}
else
{
cell.playerButton.hidden=YES;
}
