I would like to put a UIActivityIndicator in the center of my UIMapView. I have setup plenty of spinners before, but not sure what I'm missing about the MapView that is making this difficult.
The real issue seems to be that when I try to place the UIActivityIndicator onto the UIMapView in Interface Builder, it doesn't stick or it breaks the Map View.

I'm new to Navigator 2.0 in Flutter, and now I'm trying to achieve BottomSheet behavior using declarative approach. Unfortunately, I only managed to come up with quite a cumbersome way to do that so I'm wondering if there's an easier way.
I'm building a shopping app and I want to show the item details card that slides out from the bottom of the screen, dimming the previous page (as shown in picture), when user taps on item in a list. I also want to allow url support, so that /item/id opens home page and then shows the details card over it.
So how I think this could be done is to push (or to add to Navigator's pages array in case of Navigator 2.0) custom non-opaque page with no transition animation using TransitionDelegate and PageRouteBuilder, and then animate dimming and sliding by hand using animation controllers. But this approach seems unnatural (and genuinely scares me to be honest) and it's still not clear to me how to handle back button in this case (Do I need to somehow notify the page to play closing animation from Navigator's onPopPage, is this the way to do this?).
If anyone has an experience of implementing similar feature, I would really appreciate sharing it! Or maybe you have come up with more elegant solution, then tell me about it and I'll give it a try! Thanks!
Getting started with xCode 4.6.3 and I'm running into a hiccup.
I've built a simple app using the UIWebView to display a local HTML file and it's contents. I used that to debug any issues with the HTML and/or image displays and I'm all set.
Now I need to recreate that within a larger project I've built with storyboards for all my navigations between multiple view controllers. My issue comes when I'm trying to control-click drag from the WebView into the ViewController.h code below the #interface like many tutorials show, and that worked fine within my smaller single view controller app. It won't do it. I know I'm missing something obvious here. Am I going to have the set up these screens (I have multiple ones to do this same way) as separate xib files and add them into my main project?
Thanks for any help and clarification.

You can create a class called for example myWebViewController and in Interface builder add a UIWebView to it. The control+drag to the header file will work.
Every time you want a UIViewController that has a browser in it, define its class as myWebViewController in Interface Builder.
Try not to repeat code. If you see UIViewControllers or any other UIView...that do the same thing, you can group them into a class that you use over and over.
I'm developing an App with some maps functionalities (among other things), I'd like to draw a map from my current location to a given destination, but I do not want to use the shareadapplication, The shared application does not have a BACK button for example and some other navigation items I already have.
I want to do it in my own viewcontroller with mkmapview on it.
I already have the code to place the pin annotations, what I need is to trace the driving directions from A to B.
The other option is to use the [[UIApplication sharedApplication] openURL:url] call to appear inside the viewcontroller window so I can keep my navigation items.
Any ideas?

You can't do the "other option". iOS apps do not run inside windows that you can put within your app, they are full screen apps and you can make you app switch to them, but you can't make other apps switch back to yours.
So, the big question is, where are you going to get driving directions from? Check out GoogleMapsSDK, OpenStreetMap and CloudMade, because iOS maps won't give you the directions.
I've currently got two view controllers A and B, A uses a segue to push B and this works back and forth nicely, however based on some button presses in view controller B i want to change the text within a UITextView in controller A.
I've had a look at previous posts but i'm a novice at present and was confused by the way in which i should go about doing this.
I'd love to be able to get my head around how interactions are best done between various parts of the app. Also i was wondering if there is a way i can tap into a segue returning to trigger some other code.
Thanks
Edit:
OK perhaps i was a little bit limited with my information, from what i can gather reading other posts they are manually creating a variable for the viewcontroller (A) in viewcontroller (B) then accessing it in the second view controller (B) and setting a variable (property and synthesize) to edit that way, however i have the viewcontrollers embedded in a navigation controller and using a push setup in the storyboard (GUI system). I'm not sure if i have to create a variable to do this or if because they exist in the storyboard there is another way, if someone could just point me in the direction of a post that helps to explain this (i am looking at the moment too) i'd be very grateful.
OK well here's how i got it to work but i imagine there are:
A: Better ways to do it.
B: Changes depending on your setup.
I had my two view controllers embedded in a navigation controller, and used a segue push to access the second view controller each had a different class (all setup in the storyboard thing).
To get it working for me i did the following:
I have a singleton (a class that stores all my data but is global to the app so the variables can be accessed from anywhere in the app) this allows me to have variables that i can access from any view controller. A great tutorial on this can be found here
I then created an NSString variable (passedNote) and updated the value of this variable from the ViewController B, when my button was pressed.
Next when viewController A is loaded (in the viewWillAppear: (BOOL)animated method) i append or replace the value of the textview (dependent on some logic) I have with the global variable (passedNote).
Hope this helps anyone who had the problem.
if you use the Google Plus App on Android and switch to the Stream, you get a view where you can swipe to the left and right between the All circles/Incoming/Nearby-Stream. What view component is used for this? Is this a standard Android component? Or where can I find democode how i can build such a view component?
You should take a look at the ViewPager from Android Compatibility Package for the desired widget/swipe navigation. Find more about it here
http://developer.android.com/sdk/compatibility-library.html
Also, checkout this recently posted tutorial and some sample code on ViewPager by Richard:
http://geekyouup.blogspot.com/2011/07/viewpager-example-from-paug.html
It is a combination of a ViewPager together with an indicator for where you are currently and where you can go swiping left and right.
A sample of how this can be done along with code you can use in your own apps may for example be found here. I've played with this code a little and it works pretty well.
None of the default widgets/views. I guess, it's some kind of a custom view with swipe functionality.
Honeycomb opens up a few new widgets which seem to have these functionality. Have a look here.

I used APKTool to take a look at what's going on. Hopefully it is okay to post this here. This is from version 1.0.2 of the G+ APK.
removed google+ app code as per CommonsWare's suggestion
So, it looks like they're using standard views, though perhaps with a good deal of gesture detection and smooth animation magic.
EDIT) If you really want to know about the exact inner-workings of what is going on in the Stream activity, I suggest you use APKTool yourself and examine the .smali code
