I'm trying to make my app detect when it is the first launch and whether or not a UIAlertView will popup again.
When the UIAlertView should be popping up, it isn't. Am I doing something wrong here?
Code:
- (void)viewDidLoad
{
[super viewDidLoad];
BOOL firstBoot = [[NSUserDefaults standardUserDefaults] boolForKey:@"firstBoot"];
BOOL showAgain = [[NSUserDefaults standardUserDefaults] boolForKey:@"showAgain"];
if ((firstBoot) || (showAgain))
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Check the 'About' tab for help!"
message:@""
delegate:self
cancelButtonTitle:@"Don't show again"
otherButtonTitles:@"OK", nil];
[alert show];
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"firstBoot"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == [alertView cancelButtonIndex]) {
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:@"showAgain"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSDictionary *defaultUserDefaults = @{ @"firstBoot" : @YES, @"showAgain" : @YES };
[[NSUserDefaults standardUserDefaults] registerDefaults:defaultUserDefaults];
return YES;
}
