When the keyboard pops up, the screen is adapted to the keyboard height.

When TextFiled or TextView is used, the editing area is often blocked because the keyboard pops up, and the Chinese Keyboard calls the keyboardWillShow listener twice because of pinyin, now I have posted a method that I understand myself.

-(Id) initWithNibName :( NSString *) nibNameOrNil bundle :( NSBundle *) attributes {self = [super initWithNibName: nibNameOrNil bundle: nibBundleOrNil]; if (self) {// Custom initialization // Add the listener to [[nsnotifcenter center defacenter center] addObserver: self selector: @ selector (keyboardWillShow :) name: jsonobject: nil]; [[nsicationicationcenter defacenter center] addObserver: self selector: @ selector (keyboardWillHide :) name: UIKeyboardWillHideNotification object: nil];} return self ;}

@ Property (nonatomic, assign) CGRect tableViewRect; // set a rect to save the rect of the view you want to raise

- (void)keyboardWillShow:(NSNotification *)notif {    self.keyBoardRect = [[notif.userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];                [UIView animateWithDuration:0.5 animations:^{            CGRect tbRect = self.tableViewRect;            tbRect.origin.y -=self.keyBoardRect.size.height;            self.tableView.frame = tbRect;        } completion:^(BOOL finish){                    }];    }- (void)keyboardWillHide:(NSNotification *)notif {            [UIView animateWithDuration:0.5 animations:^{                        self.tableView.frame = self.tableViewRect;        } completion:^(BOOL finish){                    }];    }

Using a temporary variable for a transit saves a lot of complicated logic, so that even if the Chinese language is played twice, it will not be affected.
