I am working on such a project where apps do the following things:
viewController
by pressing "Go" buttonNow, Here I monitor one region, after that another one. So the number is actually one. But I know the maximum number of regions one apps can monitored by "Region Monitoring" is 15. Now my question is in this case should I handle this maximum number of region issue or not? If yes, then how?
One more thing I want to add is, there are some solution of it, which is only work for iOS 6 and earlier. So please let me know if there have some solution of handling number of "region" monitored by "RegionMonitoring", based on users current location in iOS7.
It will be a great pleasure to me if one can give the answer or any suggestion to finish my apps required requirements.
If you check the docs, max limit is 20. When you exceed this number, the iOS
will release monitoring of the oldest region (think its like its a FIFO queue). Make sure you keep the radius smaller than maximumRegionMonitoringDistance
. So in other words you don't need to worry about max limit, you can make sure this by implementing didStartMonitoringForRegion:
delegate.
But, If you want to control number of regions being monitored by yourself, you can always stop monitoring a region using stopMonitoringForRegion:
You can get a list of regions being monitored with the property monitoredRegions
. You can always clear up the region you don't need any more. It's a good practice to keep it minimum as it does effect the battery and app performance.
I'm using following code to clear up all my regions when required.
for (CLCircularRegion *region in self.locationManager.monitoredRegions) {
[self.locationManager stopMonitoringForRegion:region];
}
But in your case, I would suggest using a constant for Region identifier (e.g. "MY-REGION"), as you cannot monitor two regions with same identifier, adding an other region with the same id removes previously monitored region automatically.
CLCircularRegion *region = [[CLCircularRegion alloc] initWithCenter:coordinate radius:50.0f identifier:@"MY-REGION"];
[self.locationManager startMonitoringForRegion:region];
