textview键盘遮掩问题

1，在viewdidload里面  写一个方法 

    [self registerKeyBoardAction];

2，实现这个方法

#pragma mark - 注册键盘弹起与消失事件

-(void)registerKeyBoardAction{

    

    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(keyBoardWillHideNotifcation:) name:UIKeyboardWillHideNotification object:nil];

    

    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(keyBoardWillShowNotifcation:) name:UIKeyboardWillShowNotification object:nil];

}

-(void)keyBoardWillHideNotifcation:(NSNotification *)notifcation{

    //    [_detailsTX resignFirstResponder];

    [self.view resignFirstResponder];

    [self.view endEditing:YES];

    _myTableView.contentInset=UIEdgeInsetsZero;

    

}

#pragma mark - 键盘消失与显示通知方法

-(void)keyBoardWillShowNotifcation:(NSNotification *)notifcation{

    

    self.view.frame = [[UIScreen mainScreen] bounds];

    

    //获取键盘的高度

    NSValue *value = notifcation.userInfo[@"UIKeyboardFrameEndUserInfoKey"];

    

    CGRect keyBoardFrame;

    [value getValue:&keyBoardFrame];

    _myTableView.contentInset=UIEdgeInsetsMake(0, 0,keyBoardFrame.size.height, 0);

}

以上方法不好用

第二种  是针对textview键盘弹起

-(void)textViewDidBeginEditing:(UITextView *)textView{

    if(textView == _textview){

        _textview = (JSTextView *)textView;

    }

    

    float offset = 0.0f;

    NSTimeInterval animationDuration = 0.30f;

    

    [UIView beginAnimations:@"ResizeForKeyBoard"context:nil];

    

    [UIView setAnimationDuration:animationDuration];

    

    float width = _myTableView.frame.size.width;

    

    float height = _myTableView.frame.size.height;

    

    CGRect rect = CGRectMake(0.0f, offset-30 , width, height);

    

    _myTableView.frame = rect;

    

    [UIView commitAnimations];

}

-(void)textViewDidEndEditing:(UITextView *)textView{

    [UIView beginAnimations:@"ResizeForKeyBoard"context:nil];

    

    [UIView setAnimationDuration:0.3f];

    CGRect rect = CGRectMake(0.0f, 64 , SCREENWIDTH, SCREENHEIGHT-64);

    

    _myTableView.frame = rect;

    

    [UIView commitAnimations];

    

}

不好用

第三种是第三方

IQKeyboardManager 是第三方

@property (nonatomic, strong) IQKeyboardReturnKeyHandler    *returnKeyHandler;

    self.returnKeyHandler = [[IQKeyboardReturnKeyHandler alloc] initWithViewController:self];

    self.returnKeyHandler.lastTextFieldReturnKeyType = UIReturnKeyDone;

     [IQKeyboardManager sharedManager].shouldResignOnTouchOutside = YES;
