I am new to XCode and iOS programming. So please assume nothing ...
I am trying to incorporate the inappsettings bundle into my project. It is the 3rd party product found at http://inappsettingskit.com/
I have included all (I think) the files from the kit as well as their settings.app bundle. Through IB, I have built a tab bar where each tab item is a navigational controller. The view of my "Settings" tab is a view controller of class IASKAppSettingsViewController.
When I run my app, the default setting screen included in the kit displays and everything seems to run correctly.
However, I cannot figure out how to actually use the settings that I select in my app. I believe that the settings are stored in [NSUserDefaults standardUserDefaults], but when I query this as below, NSString* s always comes back as nil.
NSUserDefaults* d = [NSUserDefaults standardUserDefaults];
NSString* s = [d objectForKey:#"ROOKIE"];
I have also tried initializing [[NSUserDefaults standardUserDefaults] as follows:
[[NSUserDefaults standardUserDefaults] registerDefaults:[NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"Root~iphone.InApp" ofType:#"plist"]]];
I have added the key "ROOKIE" to the Root~iphone.InApp.plist file included in the Settings bundles. I put "ROOKIE" in the "key" column and some string value in the "value" column.
Maybe here is where I am doing something wrong? I don't really understand how the .plist files work and if I am accessing the correct one, or if I am doing it in the right way. I have played around and I can't seem to extract any value from any .plist file so it would seem it's my approach rather than the file?
Any insight would be appreciated.

Is there an alternative to InAppSettingsKit that is simpler? I find myself needing only 20% of what it offers.
How about ESCOZ's QuickDialog library? Seems like a reasonable alternative.
Well, one alternative is to just build your own settings panel with a regular UIViewController and some buttons and switches, etc. and then save the settings using NSUserDefaults, e.g.
- (IBAction)mySettingSwitchAction:(UISwitch *)theSwitch
{
//save the switch setting
[[NSUserDefaults standardUserDefaults] setBool:theSwitch.on forKey:#"myPreferenceName"];
}
then you can load it again anywhere in your app using
BOOL theValueISet = [[NSUserDefaults standardUserDefaults] boolForKey:#"myPreferenceName"];
Values you set in NSUserDefaults are persistent so if the app is closed and opened again they retain their values. You can call synchronize on NSUserDefaults to force it to save/load the values but this happens automatically on app open/close anyway.
I have a settings bundle with the following settings. When I build/install my app the Settings.app appears to work correctly. I see the default value and everything. But in my app when trying to read the text field's text I get nil.
Here is how I read the settings
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *temp = [defaults stringForKey:#"url_preference"];
The defaults in the settings bundle are only read by the Settings app. See this question for details and workarounds.
I am creating an app which requires the users to enter certain values when the app is used for the first time.
A settings screen with 4 UITextFields and a UIPicker.
This settings view can be accessed later using a button from the mainscreen.
Somebody please suggest some ideas
Thanks
Use the NSUserDefaults and set a BOOL or a NSDate to indicate that you app has been used for the first time.
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:#"firstUse"]
i had done localisation by changing the language of iPhone through localisableString and by different xib which works only with NSLocale method ,but the requirement of app is to localised it by changing the language in app setting view irrespective of iPhone language..
Sounds like a stupid requirement, but anyway: You can change the language of your app by setting an array with the order of preferred languages for the user defaults key #"AppleLanguages", e.g.:
//Set language to German:
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[NSArray arrayWithObject:#"de"]
forKey:#"AppleLanguages"];
Note however that this only affects strings/nibs you load afterwards, so you might need to reload your UI after changing the setting.
I want to remember the last screen of my app, means if I reopen my app, app should navigate me to the last screen where I were just before exiting app.

Take a look at the NSUserDefaults API.
You could save an object for the current screen in the NSUserDefaults then check for that object on launch.
Create a NSMutableDictionary object when a view loads, and change it's value each time, and store it in the user defaults.
NSMutableDictionary *currentScreen = [[NSMutableDictionary alloc] init];
[currentScreen setObject:#"AboutPage" forKey:#"screen"];
NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
[standardUserDefaults setObject:currentScreen forKey:#"lastScreen"];
Then when the app loads, check the user defaults "lastScreen" key and load the appropriate view.
Hope this helps.
in iOS4 it's done automatically, because when you quit your application it's actually enters the background mode and doesn't quit. So when you "launch" it again, it opens at the same place the user left.
Previous versions of iOS don't have this feature and you should take care of it by yourself.
Depending on your application, you may want to think about using the Three20 library. This library has the sort of persistence you are looking for built in.
