根据入门指南添加了所有内容。地图加载,我可以GMSMarker
毫无问题地将 s 添加到地图中。我有一种绘制多边形的方法,应用程序每次都会崩溃。
方法:
-(void)drawPolygon
{
GMSMutablePath* path = [[GMSMutablePath alloc] init];
[path addCoordinate:CLLocationCoordinate2DMake(-91.13343811039999, 42.6450805664)];
[path addCoordinate:CLLocationCoordinate2DMake(-91.0180969238,42.6452140808)];
[path addCoordinate:CLLocationCoordinate2DMake(-90.8977890015,42.6446838379)];
[path addCoordinate:CLLocationCoordinate2DMake(-90.89622497560001,42.6696586609)];
[path addCoordinate:CLLocationCoordinate2DMake(-90.8959732056,42.6752548218)];
[path addCoordinate:CLLocationCoordinate2DMake(-90.88994598390001,42.6732940674)];
GMSPolygon* poly = [GMSPolygon polygonWithPath:path];
poly.strokeWidth = 2.0;
poly.strokeColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1.0];
poly.fillColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.4];
poly.map = _mapView; //CRASH!!
}

我根本不想使用 MapKit。没有创建其他 OpenGL 上下文。任何人都可以为我提供 GMSPolygon 的工作示例吗?我相信我的例子遵循官方的例子。
使用 SDK 版本 1.3.1。ARC 已启用。使用情节提要的单视图应用程序。平移/缩放其他一切都可以,只是不能绘制形状。
