Google Place自动完成功能无法完美运行

我试图从Google Place进行“地方自动完成”，然后直接从网站上复制粘贴代码，这里是Google Developer，我也已经设置了api键，但是问题是为什么当我尽可能键入地方时结果看起来很奇怪在图片上看到似乎可行，但并不完美。这是我的代码：

import UIKit
import GoogleMaps

class FetcherSampleViewController: UIViewController {

  var textField: UITextField?
  var resultText: UITextView?
  var fetcher: GMSAutocompleteFetcher?

  override func viewDidLoad() {
    super.viewDidLoad()

    self.view.backgroundColor = UIColor.whiteColor()
    self.edgesForExtendedLayout = .None

    // Set bounds to inner-west Sydney Australia.
    let neBoundsCorner = CLLocationCoordinate2D(latitude: -33.843366,
      longitude: 151.134002)
    let swBoundsCorner = CLLocationCoordinate2D(latitude: -33.875725,
      longitude: 151.200349)
    let bounds = GMSCoordinateBounds(coordinate: neBoundsCorner,
      coordinate: swBoundsCorner)

    // Set up the autocomplete filter.
    let filter = GMSAutocompleteFilter()
    filter.type = .Establishment

    // Create the fetcher.
    fetcher = GMSAutocompleteFetcher(bounds: bounds, filter: filter)
    fetcher?.delegate = self

    textField = UITextField(frame: CGRect(x: 5.0, y: 0,
      width: self.view.bounds.size.width - 5.0, height: 44.0))
    textField?.autoresizingMask = .FlexibleWidth
    textField?.addTarget(self, action: "textFieldDidChange:",
      forControlEvents: .EditingChanged)

    resultText = UITextView(frame: CGRect(x: 0, y: 45.0,
      width: self.view.bounds.size.width,
      height: self.view.bounds.size.height - 45.0))
    resultText?.backgroundColor = UIColor(white: 0.95, alpha: 1.0)
    resultText?.text = "No Results"
    resultText?.editable = false

    self.view.addSubview(textField!)
    self.view.addSubview(resultText!)
  }

  func textFieldDidChange(textField: UITextField) {
    fetcher?.sourceTextHasChanged(textField.text!)
  }

}

extension FetcherSampleViewController: GMSAutocompleteFetcherDelegate {
  func didAutocompleteWithPredictions(predictions: [GMSAutocompletePrediction]) {
    let resultsStr = NSMutableString()
    for prediction in predictions {
      resultsStr.appendFormat("%@\n", prediction.attributedPrimaryText)
    }

    resultText?.text = resultsStr as String
  }

  func didFailAutocompleteWithError(error: NSError) {
    resultText?.text = error.localizedDescription
  }
}

谁能帮我？

释放

这是因为prediction.attributedPrimaryText是属性字符串。试试下面的代码

func didAutocompleteWithPredictions(predictions: [GMSAutocompletePrediction]) {
    let resultsStr = NSMutableAttributedString()
    for prediction in predictions {
        resultsStr.appendAttributedString(prediction.attributedPrimaryText)
        resultsStr.appendAttributedString(NSAttributedString(string: "\n"))
    }
    resultText?.attributedText = resultsStr
}
