Changin App Icon on AppState

[Mac]

HI Folks,

i´m new to iPhone Development and have, hopefully a simple question.

I´d like to change my App Icon from inside my appliction.
For instance: I change a setting in my app, based on that the icon should change.

Is there any chance to implement that?

I´ve seen it on the Calendar App on the Iphone.

Just another question.

I´ve searched the hole API, but i cant find a way to disable/enable the WiFi via my App.

Thank you!!!

You haven't been able to find it because you can't turn on or off system settings, including WiFi, 3G, location services, etc.

Thanks for that.

That's a good point about the calendar app. Does anyone know if you could make the Icon.png just an Objective-C class that spits out a png? Kind of like PHP, where you can hide PHP script inside say a jpg and use header() to tell the browser it's an image.

i think that will not work. but i dont know it exactly.
probably this task will work. be careful its just an idea that comes this night

what if we can replace the Icon.png via our app on the iphone itself. i think that isnt a hard task to do. some i/o operations and everything is fine.
but if this has to work, we must have access to the filesystem where iphone puts its appdata. at this point, i dont know if this is possible.

i´ll try it and give a feedback.

Actually, you do have access to where your icon.png file is stored, but I don't know whether or not you can change it from inside your program. To access your resource path (the place where your binary, NIBs, and other picture files are) you can do the following. In this example I'll show how to access the path to the icon.png.

NSString *path = [[NSBundle mainBundle] resourcePath];
NSString *iconPath = [path stringByAppendingPathComponent:@"icon.png"];

Like I said, you have access to the resource path, but I don't know if you can change anything that's stored there. Furthermore, even if you could, it would probably require registering your icon with the same service that updates the Calendar icon since most changes to things on SpringBoard require re-springing before they show up.

You can't write to the bundle area.

do you mean the number at the top right? that is controlled byt he app...

Not possible, unfortunately. By changing the icon you'd break the codesign and you'd be unable to launch the app. The bundle must stay as it is, nothing in it can change.

You can add a badge to the icon, but only when your app is active. When Push Notification comes about you'll be able to add a badge without your app being open.

No, I know about that one. I'm talking about the icon itself...the date changes every day...
