最近做的ios输入键盘在ios5上面有问题，主要是ios5上面中文键盘，会对出来一块，我原来用的是toolbar和输入键盘不是在一起的，而位置是写死的，这样就造成了ios5上面会遮盖，在网上找了下，解决方法如下，实际上就是获得输入键盘的高度，而不要写死位置，这样也避免以后出问题。
- (void)viewDidLoad
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillShown:)
name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHidden:)
name:UIKeyboardWillHideNotification object:nil];
}
- (void)keyboardWillHidden:(NSNotification*)aNotification
{
}
- (void)keyboardWillShown:(NSNotification*)aNotification
{
NSDictionary* info = [aNotification userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;//得到键盘的高度
}
- (void)dealloc {
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
[super dealloc];
}
