my app program use coremotionmanager and locationmanager too.when i start the program, i found this error.
I\'m trying to move two buttons around using the accelerometer in xcode.I have the first button working, when I call startDrifting, but when I call startDrifting2 for the second button, nothing is hap
I just want to know that when we call the method of startGyroUpdates with CMMotionManager and fix some updateInterval say to 1.0/60.0 , then开发者_JAVA百科 is there any delegate method that we have to
analyzing the deviceMotion.timestamp i saw that the the update frequency set in DeviceMotion is not the actual frequency of update.
How can I determine the tilt location in the y direction on my iOS app? First I tried playing with the accelerometer. But the accelerometer values change even if the iPhone isn\'t tilting. Then I trie
I have a class with an ivar: @interface myCoolClass:NSObject { CMAttitude *referenceAttitude; } In my implementation have these selectors:
The code below is a near replica of the Shake and Bake example from Beginning Iphone 4 Development.It is lacking a BOOL if statement before CMAcceleration acceleration = accelerometerData.acceleration
I have been looking at the Accelerome开发者_如何学Cter Graph example in the iOS Developer library and I have a question about one of the variables that is used...
I can use this method of the Core Motion framework: - (void)startAccelerometerUpdatesToQueue:(NSOperationQueue *)queue withHandler:(CMAccelerometerHandler)handler
Do the sensor fusion algorithms of Core Motion take advantage o开发者_开发百科f the Kalman filter?Update on June 22, 2016
