7.2 Handling the Events of a Map View

如何处理事件
在苹果的世界里，当然是delegate

self.myMapView.delegate =
self;

@protocol MKMapViewDelegate;

@interface ViewController :
UIViewController<MKMapViewDelegate>

@end

-(void)test7_1
{

self.view.backgroundColor = [UIColor
whiteColor];

self.myMapView = [[MKMapView
alloc]
initWithFrame:self.view.bounds];

/* Set the map type to Satellite */

self.myMapView.mapType
= MKMapTypeStandard;

self.myMapView.autoresizingMask
= UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;

/* Add it to our view */

self.myMapView.delegate =
self;
[self.view
addSubview:self.myMapView];
}
- (void)viewDidLoad
{

[super
viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.
[self
test7_1];
}

- (void)mapView:(MKMapView *)mapView regionWillChangeAnimated:(BOOL)animated
{

NSLog(@"%s",__FUNCTION__);
}

- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{

NSLog(@"%s",__FUNCTION__);
}

- (void)mapViewWillStartRenderingMap:(MKMapView *)mapView
NS_AVAILABLE(10_9,
7_0)
{

NSLog(@"%s",__FUNCTION__);
}
