IOS8 after the third-party keyboard gets the wrong height

IOS8 after the Apple can install a third-party keyboard,

By breakpoints we will find that after using a third-party keyboard,

The keyboard will pop up method:-(void) Keyboardwillshow: (nsnotification *) notification will execute three times,

The height of the three times is: 0:216:282. We find that what we need is the height of the third time.

We need to register the keyboard to hide and display the notifications:

[[Nsnotificationcenter defaultcenter]addobserver:self selector: @selector (keyboarddidhide:) Name: Uikeyboardwillhidenotification Object:nil];

[[Nsnotificationcenter defaultcenter]addobserver:self selector: @selector (keyboardwillshow:) Name: Uikeyboardwillshownotification Object:nil];
