How to solve the issue with beacon? - ios

Question

My Problem: When I click the button, my phone will show a progress view(ask me come close the beacon), and when I come close the beacon, my phone will show a view(checkmark), and then remove the view 1.5s later. Now the view can show normally first, but when I take my phone far away from the beacon, and the view(show checkmark) will show 1s later. It's a big problem out of my mind.
My code:
onClick button
- (IBAction)chooseBLEAction:(id)sender {
self.locationManager = [CLLocationManager new];
[self _initBeaconRegion];
if (([CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorizedWhenInUse ||
[CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorizedAlways ||
[CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined) &&
[self.locationManager respondsToSelector:#selector(requestAlwaysAuthorization)])
{
[self _start];
if (self.bluetoothIsOpen) {
[self _createProgressView];
}
}else {
[self.locationManager requestWhenInUseAuthorization];
}
}
- (void)_start {
[self.locationManager startRangingBeaconsInRegion:self.targetBeaconRegion];
}
- (void)_stop {
[self.locationManager stopRangingBeaconsInRegion:self.targetBeaconRegion];
}
CLLocationManagerDelegate
- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray<CLBeacon *> *)beacons inRegion:(CLBeaconRegion *)region {
NSLog(#"searching for beacon ！");
CLBeacon *foundBeacon = [CLBeacon new];
foundBeacon = [beacons firstObject];
if (foundBeacon) {
NSLog(#"found beacon ！");
switch (foundBeacon.proximity) {
case CLProximityUnknown:
break;
case CLProximityFar:
break;
case CLProximityNear:
break;
case CLProximityImmediate:
{
[self _stop];
NSLog(#"Immediate beacon ！");
AudioServicesPlaySystemSound(1051);
[self.myProgressView removeFromSuperview];
[self _createSuceessProgressView];
self.removeProgressViewTimer = [NSTimer scheduledTimerWithTimeInterval:1.5 target:self selector:#selector(_removeSuccessProgressView) userInfo:nil repeats:NO];
break;
}
}
}
}
create progress view (close the beacon)
- (void)_createProgressView {
NSString *title = #"Please close the beacon";
self.myProgressView = [MRProgressOverlayView showOverlayAddedTo:self.view title:title mode:MRProgressOverlayViewModeIndeterminate animated:YES];
}
create success view
- (void)_createSuceessProgressView {
NSString *title = #"Success!";
self.suceessProgressView = [MRProgressOverlayView showOverlayAddedTo:self.view title:title mode:MRProgressOverlayViewModeCheckmark animated:YES];
}
remove success view 1.5s later
- (void)_removeSuccessProgressView {
[self.removeProgressViewTimer invalidate];
[self.suceessProgressView removeFromSuperview];
}
