setRegion的速度用于MKMapView
|
如果我将“ 0”中的区域更改为“ 1”，是否可以设置该动画更改的速度或持续时间？我浏览了文档和Google，但一无所获。

import MapKit extension MKMapView { func animatedZoom(zoomRegion zoomRegion:MKCoordinateRegion, duration:NSTimeInterval) { MKMapView.animateWithDuration(duration, delay: 0, usingSpringWithDamping: 0.6, initialSpringVelocity: 10, options: UIViewAnimationOptions.CurveEaseIn, animations: { self.setRegion(zoomRegion, animated: true) }, completion: nil) } }extension MKMapView { func animatedZoom(zoomRegion:MKCoordinateRegion, duration:TimeInterval) { MKMapView.animate(withDuration: duration, delay: 0, usingSpringWithDamping: 0.6, initialSpringVelocity: 10, options: UIView.AnimationOptions.curveEaseIn, animations: { self.setRegion(zoomRegion, animated: true) }, completion: nil) } }佃蒜狗掂哥
动画的持续时间，如下所示：#import <MapKit/MapKit.h> @interface MKMapView (ZoomLevel) - (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate zoomLevel:(NSUInteger)zoomLevel animated:(BOOL)animated; @end #import \"MKMapView+ZoomLevel.h\" @implementation MKMapView (ZoomLevel) #define ANIMATION_DURATION 0.5 - (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate zoomLevel:(NSUInteger)zoomLevel animated:(BOOL)animated { MKCoordinateSpan span = MKCoordinateSpanMake(0, 360/pow(2,zoomLevel)*self.frame.size.width/256); [MKMapView animateWithDuration:ANIMATION_DURATION animations:^{ [self setRegion:MKCoordinateRegionMake(centerCoordinate, span) animated:YES]; }]; }
