确定状态栏方向

Question

I am wanting to detect where the status bar is on my current view in order to determine which segue to perform. I know the preferred way to do this is to determine the device orientation, but there are two problems with this approach for me:

1.) If the device is not angled far enough away from vertical or horizontal then there is no device orientation detected and the segue doesn't happen

2.) Under certain conditions I am going to "lock" the display orientation such that even though the physical device orientation is landscape the screen is going to be locked to portrait and I will want to perform the portrait segue I have created.

The problem is that the " [UIApplication sharedApplication].statusBarOrientation = " is not returning the actual orientation of the status bar. Is there not an easy way to detect this? Otherwise I am going to have to write a bunch of messy code to keep track of this.

Answer 1

Have you tried: [[UIDevice currentDevice] orientation] ?

Note:

Depending on the design of your app it might be necessary to call [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications] . If you do that, make sure to call [[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications] at some point.

If that's not sufficient for your purpose I guess you have to manually check the accelerometer. Take a look at: Handling Motion Events for more info on how that's done.
