ios 7 initWithOverlay 已弃用

Question

这个弃用方法的替代逻辑是什么

MKPolylineView *polylineView = [[MKPolylineView alloc] initWithOverlay:overlay];
polylineView.lineWidth = 3;
polylineView.strokeColor = [[UIColor alloc] initWithRed:5.0/255 green:102.0/255 blue:48.0/255 alpha:1];


MKCircleView *circleView = [[MKCircleView alloc] initWithOverlay:overlay];
circleView.strokeColor = [UIColor blueColor];
circleView.fillColor = [[UIColor blueColor] colorWithAlphaComponent:0.4];
circleView.lineWidth = 2;

Answer 1

引用MKPolylineView和MKCircleView的文档:

// Prefer MKPolylineRenderer
MKPolylineRenderer *polylineView = [[MKPolylineRenderer alloc] initWithOverlay:overlay];
polylineView.lineWidth = 3;
polylineView.strokeColor = [[UIColor alloc] initWithRed:5.0/255 green:102.0/255 blue:48.0/255 alpha:1];

//Prefer MKCircleRenderer
MKCircleRenderer *circleView = [[MKCircleRenderer alloc] initWithOverlay:overlay];
circleView.strokeColor = [UIColor blueColor];
circleView.fillColor = [[UIColor blueColor] colorWithAlphaComponent:0.4];
circleView.lineWidth = 2;
