每当用户使用我的应用进行搜索时,它都会返回最多100个结果的数组。我需要对每个索引进行地理编码(我在每个索引处都有lat和lon),并在地图上放置一个标记。
我还需要使用NSURLSession显示https。然后,我在指定的标记位置显示每个图像。一切正常,#34;罚款"对于较低的数字,但我得到两个重大错误:
1)对于图像内容:
NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802)
2)对于地理编码器:
geoCoder error probably too many requests Optional(Error Domain=kCLErrorDomain Code=2 "(null)")
我的猜测是我做了太多请求,苹果有限制。那我怎么能解决这个问题呢?当然有一种方法可以做到这一点,或者可能是一种不同的方法?以下是显示图像的代码:
extension UIImageView {
public func imageFromUrl(urlString: String) {
if let url = NSURL(string: urlString) {
let request = NSURLRequest(URL: url)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue()) {
(response: NSURLResponse?, data: NSData?, error: NSError?) -> Void in
if let imageData = data as NSData? {
self.image = UIImage(data: imageData)
}
}
}
}
}
以下是地理编码器的代码:
for i in (0 ..< tbc.categorizedArray.count) {
//make sure that the specified index actually has a geoLon and geoLat
if var longitude :Double = tbc.categorizedArray[i]["geoLon"] as? Double {
longitude = tbc.categorizedArray[i]["geoLon"] as! Double
let latitude :Double = tbc.categorizedArray[i]["geoLat"] as! Double
//if it does, save it's location
let location = CLLocation(latitude: latitude, longitude: longitude)
//reverseGeoCode it's location
CLGeocoder().reverseGeocodeLocation(location, completionHandler: {
placemarks, error in
if error != nil {
print("geoCoder error probably too many requests \(error)")
return
}
//place the markers
if let placemarks = placemarks {
let placemark = placemarks[0]
// Add annotation
let annotation = MKPointAnnotation()
annotation.title = tbc.categorizedArray[i]["screenname"] as? String
annotation.subtitle = tbc.categorizedArray[i]["userPost"] as? String
if let location = placemark.location {
annotation.coordinate = location.coordinate
// Display the annotation
self.mapView.showAnnotations([annotation], animated: true)
self.mapView.selectAnnotation(annotation, animated: true)
}
}
})
}

-9802是App Transport Security问题。检查你的证书。
不知道地理编码器问题。
