Emulates the native Remote Notification View.

First, sorry to my poor English.

I found unintented bug by UIDeviceOrientationDidChangeNotification.

Code is received message by iOS at App state switching Foreground & Background.

so, code calls [self setUI] and creates Tap gesture and adds view overlap.

finally, when view has tap gesture, view calls onTouch function repeatedly.

My app use libs MZFormSheetController(https://github.com/m1entus/MZFormSheetController)

when notification appear after MZFormSheetController opened

MZFormSheetController will hide after HDNotificationView has show and when HDNotificationView hide MZFormSheetController will show again

It would be very useful if you added a feature to add buttons to the Notification also possible able to change the duration for how long the bar is visible for.

Prior iOS8 UIScreen instances doesn't rotate, that means that in iOS7 your HDNotificationViews in landscape they appear only at the upper top corner as they were in Portrait. To handle that you need to apply transformations according to device rotation changes. From apple doc of UIScreen: Prior to iOS 8, a screen’s bounds rectangle always reflected the screen dimensions relative to a portrait-up orientation. Rotating the device to a landscape or upside-down orientation did not change the bounds. In iOS 8 and later, a screen’s bounds property takes the interface orientation of the screen into account. This behavior means that the bounds for a device in a portrait orientation may not be the same as the bounds for the device in a landscape orientation. Apps that rely on the screen dimensions can use the object in the fixedCoordinateSpace property as a fixed point of reference for any calculations they must make.
