I am trying to create a custom navigation arrow (I don't know the exact name) without using apple or google maps. Navigation arrow in my meaning is the green thing that rotates with the phone.
An example of what I call "navigation arrow":
I know this uses the UIAccelerometer but still I have not a clue what I need to do.
So the question is, Can anyone give me some pointers to create this without using maps? Is there any tutorials out there or a Github project? Or does anyone knows the actual name of this?
You can use CLLocationManager to obtain CLLocation instances which, in turn, have course property. Or maybe try to use magnetometerData of CMMotionManager.

Is it possible to only screenshare a specific UIView using AppScreenSource?
I'm creating an iOS app which is using RealityKit to place virtual objects on screen. I'd like to share this video with the other connected user in the room. AppScreensource seems like an almost perfect solution, but I don't want to share the entire screen - just my ARView. Is there a way to do this? Or do I need to go another route?
After going through the doc. I don't find any solution for capturing a portion of the screen. AppScreensource will the whole screen.
Link to the docs - https://www.twilio.com/docs/video/ios-v4-screen-capture
maybe you can use ARView's instance method snapshot(saveToHDR:completion:). There is a working example mentioned in this blog.
What is the pop-up object used in the Apple's "Clock" app for iPad called?
The popup looks similar to a MapKit callout, but often comes out of the side of a clicked button. Apple uses the pop-up often to display pickerViews on iPad. I am wanting to use it also for iPad applications in Swift, but I cannot find the name anywhere in documentation or on StackOverflow--because I don't know what it is called and it is thus hard to find.
I already know that some may not like the simplicity of this question, but I have seriously tried and have looked through books and other documentation trying to identify what the name of it, but it is so hard to find it without knowing the name! (I've included an image of the object just to be clear, but, unfortunately, I don't have the 'reputation' for the image to show up automatically in StackOverflow)
Image: The Object/PopUp item used in the "Clock" App.
The object is a Popover, as identified by Dan.
Thank you those who contributed.
You must be talking about UIDatePicker.
I've been searching for a library or sample project that implements the following functionality, but unfortunately haven't been able to find much. Could anyone share any thoughts or point me in a general direction if experienced something similar?
I'd like create a pull-out view controller/tray whose interaction is very similar to the Google Maps iOS app (http://i.stack.imgur.com/l1QHt.png). When a user taps or pulls-up the snippet pane, the view expands until fully maximized. Essentially the same interaction as seen in the Maps app.
I'm happy to implement from-scratch if a library doesn't exist, but regardless wanted to seek any suggestions/insights before getting underway.
Thanks again for your help & advice!
I have an app where I want the user to place a marker on a map and drag a circle to define a range around that notification, exactly as in Apple's Find Friends App (when you pick one of your friends and subscribe for notifications when he arrives or leaves a certain location).
Looks like this:
The marker can be dragged and moved like always, but the solid circle on the right side is used to define a range around the marker.
Does anyone have an idea on how to implement that? Maybe someone has already implemented something like this and wants to share his code :-).
Thanks.
Ok, I found some very useful sourcecode. Here it is, in case somebody else needs it as well: https://github.com/d0ping/DBMapSelectorViewController
I want to make a a sliding up like FourSquare app.
Like this:
What I want to achieve are:
The UITableView goes all the way up to UINavigationBar.
It drags along with my finger's position.
My app also have a GMSMapView below (Google Map's API, similiar to FourSquare), I don't want the map responses to my gestures on the UITableView, I want it stays still.
Works both in iOS 6 and 7 and iPhone 4,5.
Does anybody have a framework, github's link ... that can help me fulfill this ?
Thank you.
I have been working on something very similar in the past days. This answer is actually quite good, but you will suffer a bit in terms of performance. After more tweaking, I used parts of this library. You don't need to use everything, but keep in mind the following when choosing a library:
Libs that base the movement of the map on the map.centerCoordinate are less performant than libs that base the movement on the map's frame.
You can also read a bit from this tweets exchange I had.
My thoughts about what FourSquare actually did, is that in the beginning they are using a screenshot of the map, so they are not really using a MKMapView, but an UIImageView. Once you touch it and you animate it, they switch between one and another and they start using a map. I will be using Reveal App plus this to know exactly what they are doing.
