如何在Google街景视图中添加UIImageView视图sdk for ios

Question

@IBOutlet weak var getout: UIButton! 
@IBOutlet weak var legstreet: UIImageView! 
@IBOutlet weak var viewStreett: GMSPanoramaView! 
var panoramaNear: CLLocationCoordinate2D! 
override func viewDidLoad() { 
    super.viewDidLoad() 
    panoramaNear = CLLocationCoordinate2DMake(30.274262, -97.752371) 
    //var panoramaNear = self.tmpString 
    var panoView = GMSPanoramaView.panoramaWithFrame(CGRectZero, 
     nearCoordinate:panoramaNear)   
    self.viewStreett = panoView 
    // Do any additional setup after loading the view. 
} 

当我这样写时，街景无法显示。我不得不修改 self.viewStreett = panoView到self.view = panoView.但是在这个时候UIImageView消失了。所以我的问题是如何将UIImageView添加到街景中，并且不要打扰街景的使用。

您的viewStreet将是一个加载GMSPanoramaView，因为它没有坐标。所以你不能让一个装载GMSPanoramaView等于你的panoView（viewStreet = panoView不会工作）。

取而代之，您可以将viewStreet的类型更改为UIView，现在它将像您的panoView的容器视图一样行为。然后，您可以执行viewStreet.addSubview(panoView)将您的panoView添加到容器。

示例代码：

@IBOutlet weak var viewStreet: UIView! 
    @IBOutlet weak var sampleImageView: UIImageView! 
    var panoView: GMSPanoramaView! 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     let panoramaNear = CLLocationCoordinate2DMake(30.274262, -97.752371) 

     panoView = GMSPanoramaView.panoramaWithFrame(CGRectZero, 
      nearCoordinate:panoramaNear) 

     viewStreet.addSubview(panoView) 
     viewStreet.sendSubviewToBack(panoView) 

     let equalWidth = NSLayoutConstraint(item: panoView, attribute: .Width, relatedBy: .Equal, toItem: viewStreet, attribute: .Width, multiplier: 1.0, constant: 0) 
     let equalHeight = NSLayoutConstraint(item: panoView, attribute: .Height, relatedBy: .Equal, toItem: viewStreet, attribute: .Height, multiplier: 1.0, constant: 0) 
     let top = NSLayoutConstraint(item: panoView, attribute: .Top, relatedBy: .Equal, toItem: viewStreet, attribute: .Top, multiplier: 1.0, constant: 0) 
     let left = NSLayoutConstraint(item: panoView, attribute: .Left, relatedBy: .Equal, toItem: viewStreet, attribute: .Left, multiplier: 1.0, constant: 0) 

     panoView.setTranslatesAutoresizingMaskIntoConstraints(false) 
     NSLayoutConstraint.activateConstraints([equalWidth, equalHeight, top, left]) 
    } 

如果你在你的应用程序中使用自动版式，你应该增加宽度，高度，顶部和左侧约束你panoView。

您可以在this GitHub page查看示例应用程序。

在下面的模拟器屏幕截图中，我只需在panoView之上添加标记图像即可。
