问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: iOS 6 and Location Services not working Our app's location services have stopped functioning in iOS 6. They work fine in iOS 5. When I call CLLocationManager's startUpdatingLocation method it never prompts the user for access and our app doesn't show up in the Settings Location Services page. Anyone seen this before? I really have no idea where to look. I have tried stripping down our app to just a single view

问题 I am working on my home automation app. I am using estimotes iBeacons and what I want to do is give my Home Automation Control the ability to know my proximity in my home. Each iBeacon is given a virtual switch on my Home Controller and when I come in contact with a iBeacon my device either in foreground or background will update my control to turn on my switch for when I am near a beacon and turn it off when I have wondered away from my beacon. All of this works perfectly and I am loving it,

问题 The Cardcase application lets you know if you approach a shop which you have a previous relationship with (if you've set up a tab for payments there etc.). If background running applications cannot be started automatically on device boot, how does this app therefore work? Edited to make my question clearer: I am not asking how to monitor for location changes or how to monitor for location changes in the background. My question is, if the user install this app, then adds some tabs for some

问题 There's a bug in OS 4.1 that has broken location services for some iPhone apps ( https://devforums.apple.com/message/306250 ). Basically location services fails to turn on, and doesn't even ask the user for permission to get their location. The worst thing about the bug is that it doesn't occur when you're installing the app to a device from XCode, it occurs you when you're downloading from the App Store! This makes it almost impossible to test for a fix. Not everyone's app has been affected,

问题 I have a view with a map and a button (like the Maps app once) that allows the user to center and zoom his current location on the map. If I can not use the locationServicesEnabled method (always returns YES), should I create a BOOL attribute to check if the didFailWithError method is called and know if I can call the button method? Thanks for reading. Edited: This code does not work for me. I am using the simulator. I am always getting YES when asking locationServicesEnabled. // Gets the

问题 I am new to iphone development, and i want to store CLLocationCoordinate2D object to NSUserDefaults . I am Trying [defaults setObject:location forKey:@"userLocation"]; But it gives error 'Sending CLLocationCoordinate2D to parameter of incompatible type id' So How to store CLLocationCoordinate2D into NSUserDefaults ?

问题 I've been trying to figure out how to get the user's location when the app is terminated like how the app Moves does it. The only way I know of doing so is with Significant Location Changes. However with significant location changes, the app only gets woken up either every 500 meters and only if it has been around 5 minutes past the last update. According to Apple: Apps can expect a notification as soon as the device moves 500 meters or more from its previous notification. It should not
