在UIViewController中将UITableView作为容器视图embedded

我想添加一个textfield和发送button，粘贴到uitableview的底部类似于一个聊天应用程序。 我遇到过在UIViewController中embeddedUITableView作为容器视图的注释。

但是，他们似乎缺乏如何实现这一目标的例子。 更具体的细节包括在哪里添加文本框/button和键盘出现时向上移动文本字段，等等。谢谢！

Answer 1

按照使用故事板的步骤

 1) drag a uiviewcontroller from the object library. 2) drag and drop the textfield and button and place it at the position you want 3) drag and drop a container view. 4) delete the default uiviewcontroller comes with the container view 5) drag a uitableviewcontroller and make a segue and the segue should be embedsegue. 

和键盘处理，你可以去与IQKeyboardManager库https://github.com/hackiftekhar/IQKeyboardManager

一个非常简单的聊天模式代码，你可以看看：

 #import "ViewController.h" @interface ViewController () @property UIView* containerView; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. _containerView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds]; UITableView* tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height-30)]; UITextField* tfInput = [[UITextField alloc] initWithFrame:CGRectMake(0, tableView.frame.size.height, [UIScreen mainScreen].bounds.size.width-50, 30)]; tfInput.backgroundColor = [UIColor grayColor]; UIButton* btnSend = [[UIButton alloc] initWithFrame:CGRectMake(tfInput.frame.size.width, tfInput.frame.origin.y, 50, 30)]; [btnSend setTitle:@"Send" forState:UIControlStateNormal]; [btnSend setTitleColor:[UIColor blueColor] forState:UIControlStateNormal]; [btnSend addTarget:self action:@selector(btnClicked) forControlEvents:UIControlEventTouchUpInside]; [_containerView addSubview:tableView]; [_containerView addSubview:tfInput]; [_containerView addSubview:btnSend]; [self.view addSubview:_containerView]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil]; } - (void)keyboardWillShow:(NSNotification *)notification { NSDictionary *userInfo = [notification userInfo]; NSValue* aValue = [userInfo objectForKey:UIKeyboardFrameEndUserInfoKey]; float keyboardHeight = [aValue CGRectValue].size.height; //Resize the container _containerView.frame = CGRectMake(0, - keyboardHeight, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height); } -(void)btnClicked{ [self.view endEditing:YES]; } - (void)keyboardWillHide:(NSNotification *)notification { _containerView.frame = [UIScreen mainScreen].bounds; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end
