iOS 鍵盤遮擋輸入框解決方案
//
方法一
- (void)addNotification {
[[NSNotificationCenterdefaultCenter] addObserver:selfselector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotificationobject:nil];
[[NSNotificationCenterdefaultCenter] addObserver:selfselector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification
}
- (void)keyboardWillShow:(NSNotification *)info {
CGRect keyboardBounds = [[[infouserInfo] objectForKey:UIKeyboardFrameEndUserInfoKey]CGRectValue];
float f = keyboardBounds.size.height;
self.view.frame =CGRectMake(0,0,f, 0);
}
- (void)keyboardWillHide:(NSNotification *)info {
self.view.frame =CGRectMake(self.view.frame.size.height,0, 0,0);
}
//
方法二
// 開始編輯輸入彈出鍵盤
- (void)textFieldDidBeginEditing:(UITextField *)textField {
CGRect frame = textField.frame;
int offset = frame.origin.y + 32 - (self.view.frame.size.height - 216.0);//鍵盤高度216
NSTimeInterval animationDuration =
[UIViewbeginAnimations:@"ResizeForKeyboard"context:nil];
[UIViewsetAnimationDuration:animationDuration];
//將檢視的Y座標向上移動offset個單位，以使下面騰出地方用於軟鍵盤的顯示
if(offset > 0)
self.view.frame = CGRectMake(0.0f, -offset, self.view.frame.size.width, self.view.frame.size.height);
[UIViewcommitAnimations];
}
// 當用戶按下return鍵收回鍵盤
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
returnYES;
}
// 輸入框編輯完成後，將檢視恢復到原始狀態
- (void)textFieldDidEndEditing:(UITextField *)textField {
self.view.frame =CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
}
