On my program icon i want to show how many show a number, like on the AppStore program icon, where it shows how many updates are available. How can i implement this on my own program icon?
Your application can add a badge icon number by calling:
[UIApplication sharedApplication].applicationIconBadgeNumber = 1; // any NSInteger
This is available in iPhone 2.0, but in 3.0 the application doesn't have to be running to update the number using the push notification service (requires server in the cloud).

I am using flutter_local_notifications: ^9.7.0 to show notification and that's really nice package, using that package I am available to get badge with icon "1" when notification pops up. What I would like to ask.. instead of showing "1" badge, I would like to show dot badge. Is there a way to do that using flutter_local_notifications or any other package ?
Notification Badges are Platform's entity & unfortunately, you can not do anything to change it.
As mentioned in Android docs
These dots appear by default in launcher apps that support them and there's nothing your app needs to do.
I have made local notification in iphone app. And set icon badge number.
All works good. But if i have two notification in tray and user clicks on clear button than notification deletes from tray.
But the badge number of icon remains same.
I want to set the badge number to zero.
Thanks.
use this in application didfinshlaunchingwithoptions
application.applicationIconBadgeNumber = 0;
For Swift3, you can clear badge number in your application didFinishLaunchingWithOptions with this line :
UIApplication.shared.applicationIconBadgeNumber = 0
You can used this line in anywhere in code if you want too.
What you want to achieve is only possible using the Server Notifications. You can not set badge number locally without opening the application. As you won't have any control when user clears the tray. There's no way you can set the badge count at that moment.
I'm setting my applicationIconBadgeNumber using this code:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:theIntToDisplay];
The problem is that when I delete the app from an iPad and reinstall it, the app icon still shows the previous badge number. Is this default iOS behavior or can we reset it?
I found one similar question on at Why the applicationIconBadgeNumber is not getting deleted with appliccation ? Where it stored actually?, but it didn't answer my question.
This is an expected behavior, the badge number remains for a short period after uninstall e.g for the case of an immediate re-install.
Of course you can nullify badge number after every launching the application in application:didFinishLaunchingWithOptions: method but I think it is not the case because you want badge number not to be shown right after you install app and not yet launch it. In such a case just wait after removing the application and the badge numbers cache will be cleared by iOS and then install the app again. Unfortunately without jailbreaking the device there is no way to manage badge numbers behavior manually
In your app delegate under:
- (void)applicationWillEnterForeground:(UIApplication *)application
{
}
Insert:
application.applicationIconBadgeNumber = 0;
I'm implementing a website call on button touch(in iPhone), so my browser get called in that case and website get opened.
I'm using following code:
- (IBAction) websiteButtonTouched{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"http://www.google.com"]];
}
Now what I want is to COME BACK TO MY APPLICATION FROM BROWSER as In iPhone4.0 and Up the application remain running at background we only have to call that when browser quite...
Thanks In Advance.. :P
Why not create your own in-app browser? Just put a UIWebView inside a navigation controller then put an address bar and a search bar.
Please see this question:
iPhone - Open Application from Web Page
As for returning to application where you left off -- if the device supports backgrounding (iOS4+) and your backgrounded app wasn't unloaded (due to memory shortage), the app will return the point you left it.
However, you also have to handle the returning to correct point in app yourself, in the cases that the device doesn't support backgrounding, or app was unloaded due to memory shortage: you can do this by storing information about current state of the app before it exits.
This web page has some very nice flow charts which describe app backgrounding and foregrounding etc.:

on iphone with multitasking and iOS 4.x i run my app it work properly, now if i hit the home button (send a sms) and then double click the home button to return to my app i've notice that the app run like the first time not continue where i left it what is the solution to return to the point where you click the home button.
thanks
You might want to make sure you're implementing the multitasking app delegate callbacks- check out the protocol reference: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIApplicationDelegate_Protocol/Reference/Reference.html.
