MODELIO TOOLBAR CODE
Add the highlighted code to the end of IDZWebBrowserViewController class extension. Repeat this process to connect the stop button to the stopLoading action, the refresh button to the reload action and the forward button to the goForward action.Īt this point, you are almost ready to leave Interface Builder and write some code, but before doing so click on the UIWebView and in the Attributes Inspector click the Scales Page to Fit checkbox.Ī little bit of code is needed to load a web page into your web browser. When you release, choose goBack from the popup that appears. In your storyboard control-drap from the back button on the toolbar to the UIWebView as shown below. You can do this to connect you back, stop, refresh and forward buttons to your UIWebView. In addition to creating outlets that allow your code to access elements of your UI, it also possible to connect buttons to actions in Interface Builder. Your code should now look something like this. Repeat this process for the four toolbar buttons, naming them back, stop, refresh and forward respectively. In the callout that appears when you release the drag enter webView into the name field. To create a property in your view controller to access your web view, click drag from the UIWebView on the storyboard to the class extension portion of the IDZWebBrowserViewController.m file as shown below.Ĭlick-drag from the UIView to create a property. If your screen is small it may be useful to hide your Navigator using the View > Navigators > Hide Navigator menu item, the Toolbar icon or the ⌘0 keyboard shortcut and/or your Utilities using the View > Utilities > Hide Utilities menu item, the toolbar item or the ⌥⌘0 keyboard shortcut. To get started, with the storyboard file still selected, click on the Assistant Editor ( ) you should now see the view controller implementation file displayed side-by-side with the storyboard. In this next section you will use Interface Builder to generate code to interact with the user interface. If you are having difficulty you can compare your work to this version: GitHub IDZWebBrowser Step1 You storyboard should now look like the image below. Add Flexible Space Bar Button Items between each pair of buttons.
The buttons will be bunched on the left hand side of the toolbar. In the attributes inspector, working from left to right, set the identifiers of the buttons to Rewind, Stop, Refresh and Fast Forward. Now click on the Web Browser View Controller and drag four bar button items onto the toolbar. Then select the navigation controller and in Attributes Inspector click the Shows Toolbar check box. Add a UIWebView to your view controller by dragging a Web View from the Object Library ( ) onto the view controller, then embed the view controller in a navigation controller by clicking Editor > Embed in > Navigation Controller. To create the user interface, click on the IDZWebBrowser.storyboard file.

If this all sounds a little tedious you can download the starting code here: GitHub IDZWebBrowser Step0 These changes are to allow the web browser component to be more easily integrated into other projects. I also recommend renaming the storyboard file to IDZWebBrowser.storyboard.
MODELIO TOOLBAR HOW TO
The main view controller will be called IDZViewController rename this to IDZWebBrowserViewController using refactoring (see How to Rename a Class using Refactor if you are not sure how to do this). To get started create a single view project and name it IDZWebBrowser.

So it seemed high time that I revisited the series and updated the tutorials for Xcode 5 and iOS 7. In Interface Builder, storyboards are now the preferred way of creating user interfaces (UIs).
MODELIO TOOLBAR MANUAL
Manual memory management has been replaced with Automatic Reference Counting (ARC), which greatly simplifies code. Over time, however, the tools and code presented have become outdated. By far the most popular tutorial series on this site has been the “Building a Web Browser with UIWebView” series.
