For example, 1 degree of longitude spans a distance of about 69 miles at the equator but shrinks to 0 at the poles. However, unlike longitudinal distances that vary based on the latitude, 1 degree of latitude is always about 69 miles (ignoring variations due to the slightly ellipsoidal shape of the Earth). The length of 1 degree of Longitude (in miles) equals the cosine of the latitude × 69 miles. Click the Build and Run button on the Xcode toolbar to compile and deploy the application into the iPhone Simulator.
Changes in heading of less than this amount will not generate an update message to the delegate. headingFilter = 5; // 5 degrees The default value of this property is kCLHeadingFilterNone. You should use this value if you want to be notified of all heading updates. I’m going to leave the filter set to the default value. headingFilter = 5; // 5 degrees } else { ... code ...
The panel will remain visible until calibration is complete or until you dismiss it by calling the dismissHea dingCalibrationDisplay: method in the CLLocationManager class. info Figure 4-2.
