由于iOS8,许多第三方键盘显示,我想在显示时获得键盘高度
NSDictionary* info = [aNotification userInfo]; CGSize kbSize =
[[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
但是我可以得到系统键盘的高度,但不能得到第三部分键盘(如SouGouKeyboard),它返回0而不是如何获得正确的高度?
它返回: {
UIKeyboardAnimationCurveUserInfoKey = 7;
UIKeyboardAnimationDurationUserInfoKey = "0.25";
UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 0}}";
UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 568}";
UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 568}";
UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 568}, {320, 0}}";
UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 568}, {320, 0}}";
}
你可以试试这个方法
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:)name:UIKeyboardDidShowNotification
object:nil];
- (void)keyboardWasShown:(NSNotification *)notification
{
CGSize keyboardSize = [[[notification userInfo]objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
int height = MIN(keyboardSize.height,keyboardSize.width);
int width = MAX(keyboardSize.height,keyboardSize.width);
}
