Question

i ve an application where i need to use StartMonitoringForRegion. when i put the following code in the application didFinishLaunchingWithOptions it works.

[loc startUpdatingLocation];
CLLocationCoordinate2D coord = CLLocationCoordinate2DMake(21.456372,39.287972);
CLRegion* region = [[CLRegion alloc] initCircularRegionWithCenter:coord radius:200 identifier:@"C"];
[self.locationManager startMonitoringForRegion:region desiredAccuracy:50];

but when i use the same code in another view, it does not work!! i tried to execute the code on the main thread using the following code:

if (![NSThread isMainThread])
{
    [self performSelectorOnMainThread:@selector(MonitorRegion:) withObject:pr waitUntilDone:NO];
    return;
}

但它仍然不起作用!

为何守则在“与选择方案一起完成”中起作用,

是否有任何区域监测员可能无法工作的情况?

Answer 1

经过搜索和不同的试验,我找到了解决的方法。

简单地说,这种观点必须是可见的,并且必须一直运行下去,才能使EnterRegion和ExitRegion工作。

我把所有东西都搬到了电源系统现在它正常工作了
