Question

Since the red/blue glowing banner will block quite a lot of the interface. http://d.pr/SfgW

Answer 1

This gives you the height of the status bar:

CGFloat statusBarHeight = [[UIApplication sharedApplication] statusBarFrame].size.height;

With Personal Hotspot enabled, it returns 40, and returns 20 otherwise.

Answer 2

The statusbar height is 40 even when you have an active call by pressing the home button durring a phone call, therefore you can not determine whether or not the personal hotspot is on.

Answer 3

you can get text message if any device is connect to hotspot.

UIApplication *app = [UIApplication sharedApplication];
UILabel *subviews12 = [[app valueForKey:@"statusBar"] valueForKey:@"doubleHeightLabel"];
