Mkmapview gestures

I'm using the TwinTechsFormsLib to move add pan gestures to my forms app. It does the job brilliantly. My only issue is that I'd like to add the pan gesture to a map pin. I'm guessing I'll need to create a custom renderer to do this, but was wondering if there is a simpler way to do it or if there isn't, an example on how to do this. So I guess what you mean by pan gesture on a pin is dragging it around the map.

Yes, you need a custom renderer for that, and that's not all. If you don't do that, you will not be able to drag pins Annotations on iOS. Then you need to create a custom renderer for the map. For Android you need to get the GoogleMap instance. Then you also need to create all the pins Markers on Android yourself.

Do this by creating MarkerOptions. On the MarkerOptions you can set Draggable true. Then simply add the marker to the GoogleMap instance. This is written straight out of my head. You can get alot more info and sample code from google though. I released an extended map control.

I do not really understand. You want to add tap to a pin that's what the thread title says? I think this is already provided by Xamarin.

Or do you want to implement dragging of a pin? I'm not sure what you mean by:. I want add a pan gesture to the map pin.To view 3D imagery, the ShowsBuildings property must be true and the Camera and and PitchEnabled properties must be set to create a non-vertical perspective. The iOS simulator does not render 3D buildings. The following example shows how a camera can be set to provide 3D imagery:. In iOS 7, these classes have been deprecated, and overlays now use the more efficient subclasses of MKOverlayRenderer.

A constructor used when creating managed representations of unmanaged objects; Called by the runtime. Whether the view uses the angle defined by the Camera. Whether the view uses the heading defined by the Camera.

Registers an object for being observed externally using NSString keyPath. Registers an object for being observed externally using string keyPath. Returns a strongly typed UIAppearance for instances of this class when the view is hosted in the specified hierarchy. Called after the object has been loaded from the nib file.

Overriders must call base. Obtains the appearance proxy MKMapView. Adjusts the width and height of a map rectangle so it fits in the map view's frame, including accounting for padding between the frame and the map rectangle.

Invokes the selector on the current instance and if the obj is not null, it passes this as its single parameter. Stops the specified observer from receiving further notifications of changed values for the specified keyPath.

Stops the specified observer from receiving further notifications of changed values for the specified keyPath and context. The MKOverlayRenderer associated with the specified overlay. Sets the Camera property, optionally animating.

Indicates an attempt to write a value to an undefined key.

Indicates an attempt to read a value of an undefined key. Developers should not use this deprecated method.Using the Maps SDK for iOS, you can customize the way in which users interact with your map, by determining which of the built in UI components appear on the map and which gestures are allowed.

Changes made on this class are immediately reflected on the map. The Maps SDK for iOS provides a compass graphic which appears in the top right corner of the map under certain circumstances. The compass will only appear when the camera is oriented such that it has a non-zero bearing. When the user clicks on the compass, the camera animates back to a position with bearing of zero the default orientation and the compass fades away shortly afterwards.

The compass is disabled by default. However, you cannot force the compass to always be shown. The My Location button appears in the bottom right corner of the screen only when the My Location button is enabled. When a user clicks the button, the camera animates to focus on the user's current location if the user's location is currently known.

The floor picker control appears near the bottom right of the screen whenever an indoor map is featured prominently. When two or more indoor maps are visible the floor picker relates to the building nearest to the center of the screen.

Each building has a default floor which is selected when the picker is first displayed. You can choose a different floor by selecting it from the picker.

The following gestures can be enabled and disabled programmatically. Note that disabling the gesture will not limit programmatic access to the camera settings.

It enables you to center the map on a given coordinate, specify the size of the area you want to display, and annotate the map with custom information by becoming a Map View delegate. When you initialize a Map view, you can specify the initial region for that map to display. You do this by setting the region property. A region is defined by a center point and a horizontal and vertical distance, referred to as the span.

The span defines how much of the map will be visible and determines the zoom level. The smaller the span, the greater the zoom. In addition, for 3D Flyover maps you can use two-finger gestures to change the viewing angle. You can also specify the Map type — regular, satellite, or hybrid — by changing a single property. Because MapKit. As a result, it optimizes performance on iOS devices by caching data as well as managing memory and seamlessly handling connectivity changes such as moving from a cellular network to Wi-Fi, for example.

The delegate object can be any object in your application, as long as it conforms to the MKMapViewDelegate protocol.

Maps make mobile apps more interactive and improve the user experience tremendously. In our mobile app templateswe integrated maps in several apps, such as in the Store LocatorClassifieds Appor Real Estate app. In this MapKit tutorialwe are describing our experience of working with MapKit to help you learn how to add maps to your iOS app in Swift.

Have you ever wanted to build a map in your phone application? Does it seem too difficult of a task? If so, then this article is for you. Today, we will talk about MapKit.

So, what exactly is MapKit? This class has all the features needed, such as map, satellite, or even the current location. Hand gestures may be used on the screen to change the geographical region. We can also add annotationsphotostitles and mark specific locations on the map.

Another great thing is that we can receive notifications such as changing the current location of the user or region of the map, through MKMapViewDelegate protocol. Normally, we would have a starter project for you.

Hopefully this will be an additional incentive for the readers to follow through. You can pin it to the edges of the screen or the safe area if you refer to this onefor simplicity by using auto layout constraints, of course. Do not forget to import the MapKit library, so that the code compiles successfully. It looks like this:. BOOM, it looks awesome, right? MapKit has provided us with the map and now all we need to do is observe and handle the different events such as changing the current location or region etc.

Of course, if you do not do that, your application still works and the map still displays normally. But you have to do that because location information is one of the private information belonging to users. We have to ask their permissions before getting it. If you fail to acquire permissions first, you risk your app to crash.

In the description part, you have to explain to the user why you need their permissions. Step 3 : Check the Location Service. The locationServicesEnabled function is used to check whether a user has turned on their location service or not shown in Settings on iPhones. If they have, we can continue to implement our code. Otherwise, we need to do something to let users know why they need to turn it on like sending a pop-up to inform the user.

There are five cases that we need to handle:. For the two remaining cases, you will need to send the user a notification depending on the situation, such as the user not giving permission for showing their location.

In this article, we will not focus on these cases, however, when you are working on the actual project you will also need to handle these. They are just as important as the first two. So, just keep going — we will write this line of Swift code:.

This code will show the current location of the user.In iOS, gestures like taps, pinches, pans or rotations are used for user input. In your app, you can react to gestures, like a tap on button, without ever thinking about how to detect them. To get started, click the Download Materials button at the top or bottom of this tutorial. Detecting gestures required a lot more work before UIGestureRecognizer s were available.

If you wanted to detect a swipe, for example, you had to register for notifications — like touchesBegantouchesMoved and touchesEnded — on every touch in a UIView.

This created subtle bugs and inconsistencies across apps because each programmer wrote slightly different code to detect those touches. In iOS 3. These provide a default implementation to detect common gestures like taps, pinches, rotations, swipes, pans and long presses.

Using them not only saves a ton of code, but it also makes your apps work properly. Of course, you can still use the old touch notifications if your app requires them. Open Main. Click the Plus button at the top to open the Library. Inside the Library panel, look for the pan gesture recognizer object and drag it onto the monkey image view. This creates both the pan gesture recognizer and its association with the monkey image view:.

The begin project connected two other gesture recognizers for you: the Pinch Gesture Recognizer and Rotation Gesture Recognizer. It also connected the pan, pinch and rotation gesture recognizers to the banana image view. So why did you associate the UIGestureRecognizer with the image view instead of the view itself? You could connect it to the view if that makes the most sense for your project.

But since you tied it to the monkey, you know that any touches are within the bounds of the monkey. Open ViewController.

In the document outline for Main. Select handlePan: from the pop-up. At this point your Connections inspector for the pan gesture recognizer should look like this:. Build and run and try to drag the monkey. Fix this by selecting both image views, opening the Attributes inspector and checking User Interaction Enabled. Build and run. You can now drag both image views across the screen. Apple apps and controls typically have a bit of deceleration before an animation finishes.


You see this when scrolling a web view, for example. There are many ways of doing this. Build and run to try it out. You should now have some basic but nice deceleration! Feel free to play around with it and improve it.

Controls and Gestures

If you come up with a better implementation, please share it in the forum discussion at the end of this article. Your app is coming along great so far, but it would be even cooler if you could scale and rotate the image views by using pinch and rotation gestures as well! The begin project gives you a great start. It also connected those methods to the monkey image view and the banana image view.

Every view has a transform applied to it, which gives information on the rotation, scale and translation that the view should have. Apple has many built-in methods to make working with a transform easier.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I add some subviews to it, amongst which there's also an MKMapView. The thing I am trying to achieve ist to detect a 3-finger swipe across the screen so I can react to it. Furthermore I need to distinguish between 3-finger swipe to the left or to the right.

Before I added the mapview, I was experimenting with touchesMoved etc. This is, what I was trying to do in first place! So my question is: Is there a way to use UIGestureRecognizers the way I described above to maintain my controls while keeping the functionality of the Mapview? This answer describes subclassing a gesture recogniser to ensure that it does not interfere with other recognisers. You could add a custom recogniser to MKMapView that intercepts three finger swipe and reacts appropriately but then allows all other gestures to be processed as normal by the MKMapView.

The link above give the example adding simple finger press by subclassing UIGestureRecognizer. I have had success using this method to add two finger rotate to a MKMapView without messing up pan and zoom etc. The map should not "eat" all your touches. There's something wrong with that - I have successfully added long press and tap recognizers to the MKMapView, and they worked as expected. Make sure to assign your controller the delegate of all the gesture recognizers you create, and be sure to implement the method:.

After that, it's very much up to the details of your implementation to make the gesture recognizer work with the map view. In my experience you can add your own, and it should not be interfering with your recognizers.

Some other thoughts: - Overlay an invisible user interaction enabled view over the MKMapView to take events from it. Depending on how much interaction you need on the map view you could turn this on and off, etc. Learn more. Asked 8 years, 8 months ago.
