So lets get going: First, lets create a new project by opening Xcode and clicking File On the next screen you need to choose somewhere to save the project. Also, you can choose if you want to use source control or not. In the Core Location Tutorial group, we have the App Delegate.h and implementation files.
The delegate-object pattern consists of assigning a customized CLLocation Manager Delegate object to the CLLocation Manager. Delegate property is not set to an object whose class implements CLLocation Manager Delegate. Start Updating Location( ) to get an initial fix on the user’s location in your code.But you notice that the location is always wrong and way-off.(See also "Background Updating and Deferred Mode" below.)Application developers may use either C#-style events or Apple's delegate-object pattern to track foreground location updating. In the case of location data, GPS-enabled hardware may be able to record and cache accurate location but defer the delivery to the application for some amount of time.For C#-style events, developers can use the CLLocation Manager. This "deferred mode" has several constraints: If those conditions are satisfied, the application can request deferred delivery when backgrounded by calling the CLLocation Manager. Generally, when using Xamarin.i OS, developers can freely choose whether to use C# s or Apple-style "delegate objects" to react to object lifecycle events.
