google 街景未显示

Question

我上面有一个视图控制器我已经放置了一个 UIView，它应该在单击按钮时显示街景

GMSPanoramaView *streetView;

-(void) viewdidAppear
{
...
streetView = [[GMSPanoramaView alloc] initWithFrame: self.googleStreetView.frame];
    self.googleStreetView = streetView; //self.googleStreetView located on the view controller in story board design time
}
- (IBAction)openGoogleStreetView:(id)sender
{
    //initialize streetview
    [streetView moveNearCoordinate:CLLocationCoordinate2DMake(latitude, longitude)];
    [self.tableView bringSubviewToFront:self.googleStreetView];
}

Answer 1

我只是 post 在这里回答以供记录。

执行 self.googleStreetView = streetView; 只会将 streetView 的指针指向 self.googleStreetView 但不会将其添加到您的 UI.

您需要添加 streetView 作为 subView 的 self.googleStreetView

[self.googleStreetView addSubview:streetView];
