I am developing an application with an NSTabView with multiple NSTabViewItems. Each of the NSTabViewItems has a WebView subview. The WebView works as expected except when Flash or Silverlight are running in one of the WebViews. If, while Flash or Silverlight are running, a different tab is selected, the media will stop. When that tab is selected again, the media will restart. Is there any way around this (i.e. to allow the media to continue to run when a different NSTabViewItem is selected)? Does the NSTabViewItem send a message to its subviews when a different NSTabViewItem has been selected?
I'm not sure if this is why, but try check your webviews if their shouldUpdateWhileOffscreen is enabled. If it's enabled but the other tabs still doesn't load, then I'm guessing it's the design of the NSTabView, which is something on the lines of encoding it when the tab switches away, then decoding it when the user selects that tab again. In that case, I would probably do something like having a NSTabView with empty views and put the WebViews as subviews of the content view, overlaying each other and set the WebViews as hidden/visible whenever another tabview is selected.

I've been struggling with first responder problem. I put web controller (UIWebView) inside UITableViewCell and now I would like to scroll vertically my table and not affect UIWebView (this case may be done by disabling scrolling scrollview from UIWebView). However problem appears when user zooms into web content, then I want scroll horizontally through web content and still vertically scroll in table (cause cell will be resized to zoomed content).
There is a property called 'multipleTouchEnabled' that should disable the pinch gesture, but I think the user would still be able to double-tap (assuming the cell doesn't consume this gesture). Why not, instead of creating multiple UIWebView's (which have a large overhead) don't you create one hidden UIWebView that loads a website and caches an image, then load this image into the cell.
Ultimately, if you still wanted to use the UIWebView approach, you could probably subclass it and override hitTest/touches methods or handle the gesture recognizers yourself.
Also, if this is for iOS8 I would be using the WKWebView instead.
I'm implementing an NSPopover and having it appear in the status bar by setting it as a custom view. I've set its behavior to Transient, and also added a global event monitor so that when any other application gets focus, the NSPopover goes away.
This is working fairly well but the only problem I'm running into is that click on the popover brings to focus the main window of the application. If I put the window on one space and view the popover on another space and interact with the popover, I get thrown back to the space with the main window and it gets focused. Is there a way to prevent this? Perhaps allow interaction with the popover without activating the application?
I'm working on a iPhone app which shows an mobile webform in a UIWebView. I'm using a default iOS layout with a navigation and tab bar.
The mobile webform is displayed in a UIWebView in the white area. Since the webform has a lot of input fields, we really need as must space for it as possible. Because of this, we are planing to remove the tabs in the bottom. Over time, there will be more tabs/sections, so it is not a solution to just add a button for each section in the left side of the navigation bar. On a iPad a popover could easily be used to handle this.
Is there a standard iOS layout mechanism to handle this change of sections/views without using tabs?
You could do something long the lines of Path or the new Facebook app and have the "table of contents" behind the Navbar and the navbar slides away (along with the child view) to reveal it. When done right (ie smoothly) I think the effect is really cool.
This would also work great as you add more and more options, since the table could just scroll.
Here is a framework that might be you started: http://www.cocoacontrols.com/platforms/ios/controls/iiviewdeckcontroller
I would consider replacing the navigation bar's title with a control that lets you switch between tabs. You can assign the bar's titleView property to a control or a button and it will generally do the right thing.
If you're limited to 2-3 tabs, you could simply use a UISegmentedControl.
If you want more, you could use a button which, when tapped, pops up a view that allows you to select the view you want. This could be a modal table view, or you could slide up a UIPickerView from the bottom of the screen, similar to the keyboard.
I use this technique in an app of my own, screenshots here. Tapping the button cycles between views (in this case, I'm changing the contents of the table cells); tap-and-hold slides up a picker.
Another possibility would be to arrange your different forms on pages in a scroll view with a page control at the bottom, à la Weather. The best option, though, if you’re going to have a particularly long list and want to keep your screen real estate, is probably the FB/Path-style sidebar table.
I ended up using a UIActionSheet but I think it in other situations would be more stylish to use a controller like the IIViewDeckController.
I have a UITabBarController displaying a number of settings-screens in my app. I want them to be shown on just a part of the screen for layout reasons. In fullscreen, the lists become unreadable (too wide), there are just a few controls per page making the page feel very empty, and the tabbar buttons are far away from the content (Fitts law).
Using presentModalViewController with the UIModalPresentationFormSheet style gives me the size I want. I do this on top of an empty background, since in my case it doesn't make sense to display anything behind it. The "real" working area is displayed with another presentModalViewController in fullscreen mode on top of it all.
This works but feels like a hack. One problem is, I can't make the background behind the settings dialog move in the transition to fullscreen with the UIModalTransitionStyleFlipHorizontal style.
TL;DR
Can I embed a UITabBarController non-fullscreen in another "background"-view? I can't find any information of how I would do this.

Why don't you try it out?
Create a container view of the size you want the tab bar controller to have.
Create the tab bar controller.
[containerView addSubview:tabBarController.view];
In the iPhone Objective-C app, I want to pop-up a window (which is smaller than the main view, and the app does not stop running) when a button is tapped, with textField for the user to input text, and dismiss it when it is done.
This is widely used but I really cannot google the relevant content out.
What view should I use to connect it with the button? AlertView (which seems you cannot add dialogue in), ModalView?
Are there relevant info somewhere?
Thanks.
Make the popup it's own, full-sized window. Put a UIImageView in behind your popup screen, and duplicate the results of the normal window. That way, it will look like a popup window, but it still has the proper animation speed and everything. If you do it as a real popup, the game itself will slow down and look jumpy.
You can create any view and use UIViewController's presentModalViewController: to display a modal view controller (and even animate it).
