How to make a button pull up a webview? - objective-c

i'm making an app with moviePlayerViewController, and I am trying to add a webview when the button is pressed. It's a single page app, but the button once pressed to bring up a webview. I have already put in the code to make the webview, but I don't know how to combine it with my MoviePlayerViewController. What would be the best way to do that?

React Native CLI - Creating a button in a ScrollView

Hey I'm just starting out with React Native CLI.
I want to have a button which will add an item in the ScrollView. And the new Item should lead to a new Screen when you press it. But I don't have an idea how to make this nor do I know how to google that xD. Does anyone know how I can make this?
I just have a button which leads to another screen when pressing it.
I hope someone can help me :)
First you have to clear few things and make the logic.
1)Either you want to save that item datathen show it in scroll view, make it Pressable and then u can navigate to a different screen.
Or
You just want to show the data in the scroll view. Once you reload, the data is gone. So that's my bro (In my opinion) is of no use.
For the first step .
You need to store the data in a storage and then fetch it in a scroll view,
make it Pressable and navigate to a different screen.
(hint: If you want to make it Pressable then you can fetch the data into a card component and then call that component in a scroll view).
Now grab your keyboard and start searching on it.

I have a project with a web browser inside. How do I make a back button in the navigation bar for the browser?

I need the back button to make the browser go back, instead of navigate through the different app views.
I assume the "web browser" is a UIWebView? If so, the -goBack method will go back to the prior web page.
You shouldn't use the navigation bar to do this, as the navigation bar is primarily intended for navigating the views/screens of the app. Instead, create a toolbar, put a "back button" in the toolbar (perhaps a left-pointing arrow image, as that's fairly common for web browser "back"), and hook this button to the -goBack method.
You may not be able to hook the -goBack method directly to your button, as it's strictly not an IBAction. But that's easy enough to work around:
- (IBAction)doGoBack:(id)sender {
[self.webview goBack];
}

Imitating keyboard delete key with a button

I am using a UIWebView for text and emoticon/smiley display in my app. I can input and delete the text and emoticons using the keyboard, but I want to have a button in the UI which will do the same thing. How can I imitate the keyboard delete functionality with my own button?
My guess would be that you have to set up some sort of communication between the native app and the webview so that you can pass certain events to be handled accordingly. Check out the post here NSString in UIWebview that might shed some light on how you can solve your problem.

Preventing navigationview Back Button

Is there any way to prevent the default back button behavior in the navigation bar of a navigationview?
I'm trying to use Sencha Touch 2 history and linking abilities with routers, but that requires me to essentially intercept all button taps so that I can update the url.
The back button in a navigation bar creates all kinds of nightmares as far as thats concerned, and I can supply code if someone thinks they have an alternate solution, but preventing the default back button behavior seems best (so as to play nice with browser back button)
If you want to handle back button you can use back event of navigation view which fired when the back button of the navigation view was tapped.. Refer to my previous answer on how to do it.
If you want to completely hide the back button just simply use:
Ext.select('.x-button-back').hide();
try this Ext.getCmp('navigationview's id').getNavigatorBar().hide()

Finger scrollable UIWebView when the keyboard is up

In an application that I'm writing I have a UIWebview up top and some UITextFields at the bottom that I want the user to be able to type in depending on what's in the webview. But when they touch the Text Field and the keyboard pops up, the user loses the ability to manipulate the web page to see different parts.
Is there a way to keep the keyboard up and still be able to manipulate the UIWebView?
No I believe the Keyboard is modal so you can't access the form underneath it.
You can respond to the
- (void)keyboardWillShow:(NSNotification*)aNotification;
- (void)keyboardWillHidde:(NSNotification*)aNotification;
notifications and scroll the View up or down when the keyboard is shown...
