ios - 键盘打开时更改 View 位置 - objective-c

Question

我正在开发一个聊天应用程序。该应用程序运行良好，但我在 UI 设计中遇到了一些问题。

我在 UIview 中有 UiTextField，每当用户想要输入一条消息时，键盘就会打开，UIView 会向上移动。

然后当用户按下返回按钮时，我想把它带回原来的位置。

我试过了，但它看起来像这样

我希望它支持所有设备。

这是我的代码

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];
    return YES;
}


- (BOOL)textFieldShouldEndEditing:(UITextField *)textField {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHide:) name:UIKeyboardDidHideNotification object:nil];

    [self.view endEditing:YES];
    return YES;
}


- (void)keyboardDidShow:(NSNotification *)notification
{
    // Assign new frame to your view
    [self.view setFrame:CGRectMake(0,-145,320,460)]; //here taken -110 for example i.e. your view will be scrolled to -110. change its value according to your requirement.

}

-(void)keyboardDidHide:(NSNotification *)notification
{
    [self.view setFrame:CGRectMake(0,0,320,460)];
}




- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.tv_Message resignFirstResponder];
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSLog(@"selected index : %ld", (long)indexPath.row);
}


- (BOOL)textFieldShouldReturn:(UITextField *)aTextField {
    [aTextField resignFirstResponder];
    [self.view setFrame:CGRectMake(0,0,320,460)];
    return YES;
}

谁能帮我解决这个问题。

您可以使用此链接根据设备管理您的 View 。您还需要相应地设置约束。
