ios - GMSPanoramaService requestPanoramaNearCoordinate 无结果

Question

尝试向 Google 全景请求请求坐标和指定半径。有没有办法获得坐标的最大支持半径？只是不确定我可以在 requestPanoramaNearCoordinate 中放入什么半径，因为即使我输入 10000(米)，它也不会返回任何全景图(灰色空白屏幕)，而实际上在 50 米范围内有全景图。

请求PanoramaNearCoordinate:

[panoSvc requestPanoramaNearCoordinate:self.coordinate radius:1000 callback:^(GMSPanorama *panorama, NSError *error) {
    if (error) {
        NSLog(@"StreetView is not available at latlong = %f,%f", self.coordinate.latitude, self.coordinate.longitude);
        return;
    }
    else{
        GMSMarker *marker = [GMSMarker markerWithPosition:self.coordinate];
        marker.panoramaView = panoView_;
        [panoView_ moveNearCoordinate:self.coordinate];
    }
}];

Answer 1

因此应该将panoramaView移动到panorama.coordinate，而不是目标坐标所在的位置(即self.coordinate和标记所在的位置)，请参阅下面评论后的代码。

[panoSvc requestPanoramaNearCoordinate:self.coordinate radius:1000 callback:^(GMSPanorama *panorama, NSError *error) {
if (error) {
    NSLog(@"StreetView is not available at latlong = %f,%f", self.coordinate.latitude, self.coordinate.longitude);
    return;
}
else{
    GMSMarker *marker = [GMSMarker markerWithPosition:self.coordinate];
    marker.panoramaView = panoView_;
    //------------------
    //so I should move panoramaView to panorama coordinate, not to where the destination coordinate is (which is self.coordinate and where the marker is)
    //------------------
    [panoView_ moveNearCoordinate:panorama.coordinate];
}

}];
