Hello :) I am working on an application that uses the compass and location to draw an arrow at the direction of a location. My problem is when I run my code on the emulator, all the arrows point the c
I have an accelerometer and magnetometer each producing raw X, Y and Z readouts. From this I need to determine the magnetic heading of an object.
I need to display a small compass over the mapview. Is there a standard way of ach开发者_JAVA百科ieving this? It obv needs to update as the direction the phone is pointed in changes.
I looked over SensorManager and was still开发者_运维问答 unsure, how do I detect if the phone is looking at true north (or any other direction for that matter). If you are just looking for a sample, t
has anybody already programmed a iphone compass heading tilt compensation? i have got some approaches, but some help or a better solution would be cool!
How do i get the Direction from compass when i rotate my device? i have use : - (void)locationManager:(CLLocationManager *)manager didUpdateHeading开发者_运维知识库:(CLHeading *)heading {
I calculated the wind direction and now I want to show the wind direction pointi开发者_开发百科ng to 144 degrees (on compass). How can I show this arrow on Google Maps?
This weekend I spend a few minutes thrashing together an algorithm that would take in a heading (in degrees) and return a String for the cardinal direction (I\'m using it in an android compass applica
I want to create an application could detect the number of spin when user rotates the iPhone device. Currently, I am using the Compass API to get the angle and try many ways to detect spin. Below is t
I\'m trying to develop an application that use the GPS and Compass of the iPhone in order to point some sort of pointer to a specific location (like the compass always point to the North).
