I'm having a problem I can't find any solution for it.
So basically, I'm having a compass that I want to "pop in"/"pop out" into the view, and then start to update heading, but heading stops updating after I dismiss/pop out the compass.
Like: user wants compass-> presses button-> compass pops up-> starting to rotate compass needle-> user don't want compass anymore/dismisses compass-> compass pops out of view.
So my question is: If i make one animation, the other animation stops, how do i make it possible for both to run after each other?
In showCompass:
(IBAction) showCompass:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
directionsArrow.center = CGPointMake(160, 410);
[UIView commitAnimations];
In locationManager:
float oldRadian = (-manager.heading.trueHeading * M_PI/180.0f);
float newRadian = (-newHeading.trueHeading * M_PI/180.0f);
CABasicAnimation *animation;
animation=[CABasicAnimation animationWithKeyPath:@"transform.rotation"];
animation.fromValue = [NSNumber numberWithFloat:oldRadian];
animation.toValue = [NSNumber numberWithFloat:newRadian];
animation.duration = 0.5f;
[directionsArrow.layer addAnimation:animation forKey:@"animateMyRotation"];
directionsArrow.transform = CGAffineTransformMakeRotation(newRadian);
In dismissCompass:
-(IBAction) dismissCompass {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
directionsArrow.center = CGPointMake(160, 410);
[UIView commitAnimations];
[locationManager stopUpdateHeading];
}
New code: *Show:*
[UIView animateWithDuration:1.f
animations:^{
compassDial.center = CGPointMake(160, 504-92);
pushView.center = CGPointMake(160, 500-92);
//directionsArrow.center = CGPointMake(160, 502-92);
} completion:^(BOOL finished) {
directionsArrow.hidden = NO;
[locationManager startUpdatingHeading];
}];
In locationManager:
- (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading{
float oldRadian = (-manager.heading.trueHeading * M_PI/180.0f);
float newRadian = (-newHeading.trueHeading * M_PI/180.0f);
CABasicAnimation *animation;
animation=[CABasicAnimation animationWithKeyPath:@"transform.rotation"];
animation.fromValue = [NSNumber numberWithFloat:oldRadian];
animation.toValue = [NSNumber numberWithFloat:newRadian];
animation.duration = 0.5f;
[directionsArrow.layer addAnimation:animation forKey:@"animateMyRotation"];
directionsArrow.transform = CGAffineTransformMakeRotation(newRadian);
Dismiss:
[UIView animateWithDuration:1.f
animations:^{
compassDial.center = CGPointMake(160, 700);
directionsArrow.center = CGPointMake(160, 700);
} completion:^(BOOL finished) {
[locationManager stopUpdatingHeading];
}];
Thanks in advance.
