I'm writing a code for WatchOS2 extension that uses CMAccelerometerData.
Built with no error, running correct scheme, installed in Apple Watch device, but nothing happend.
Can not even stop breakpoint on first line.
Something missing ?
@implementation ExtensionDelegate
- (void)applicationDidFinishLaunching {
motionManager = [[CMMotionManager alloc] init];
motionManager.accelerometerUpdateInterval = 0.1;
if (motionManager.accelerometerAvailable) {
[motionManager startAccelerometerUpdatesToQueue:[NSOperationQueue currentQueue]
withHandler:^(CMAccelerometerData *accelerometerData, NSError *error) {
double xx = accelerometerData.acceleration.x;
NSLog(@"%lf", xx);
}];
}
}
@end
