我正在使用swift为iOS 9.3编写应用程序,需要一张地图来显示用户位置.我初始化CLLocationManager及其委托,我配置info.plist 隐私 - 位置使用说明字符串并调用requestWhenInUseAuthorization但它不显示任何授权请求.
这是我的代码:
import UIKit
import MapKit
class DetailController: UIViewController, CLLocationManagerDelegate {
var locManager: CLLocationManager!
@IBOutlet var myMap: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
mostraPosizione()
}
func mostraPosizione(){
locManager = CLLocationManager()
locManager.delegate = self
locManager.desiredAccuracy = kCLLocationAccuracyBest
let authorizationStatus = CLLocationManager.authorizationStatus()
if (authorizationStatus == CLAuthorizationStatus.NotDetermined) {
locManager.requestWhenInUseAuthorization()
} else {
locManager.startUpdatingLocation()
}
myMap.showsUserLocation = true
}
func locManager(manager: CLLocationManager,
didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if (status == CLAuthorizationStatus.NotDetermined) {
locManager.requestWhenInUseAuthorization()
} else { …我正在使用TestFlight测试iOS应用程序.我已经成功测试了8个Build预发行版,但现在它已经不再适用了.
我已经上传内置版本并且已经Apple批准,外部测试人员的邀请已经发送并正确接收,但是当他们打开TestFlight并尝试下载应用程序时,下载会在结束前停止,并且alertView说:
Your request couldn't be completed
注意:我已尝试在不同的设备上下载,但没有一个工作.
如果没有完成下载,TestFlight也会增加安装计数.
我已经上传了今天早上的内置版.
我正在使用STL priority_queue来收集我自己的类Lettura的对象.
//---------LETTURA----------
enum Priority {zero, standard, urgent};
class Lettura{
public:
int valore;
char sensore;
Priority priorita;
Lettura(): valore(0),sensore('\0'),priorita(zero){}
Lettura(const int val, const char s='\0', const Priority p=zero): valore(val),sensore(s), priorita(p){}
friend ostream& operator<<(ostream& out, const Lettura & lett);
};
我希望它们按照渐进式"priorita"的顺序弹出,但我也希望在普通队列中使用FIFO策略弹出相同优先级的元素.我以随机顺序获得相同优先级的元素:
top: l5 urgent
top: l1 standard
top: l4 standard
top: l6 standard
top: l2 standard
top: l3 standard
我希望FIFO顺序中具有相同优先级的元素:
top: l5 urgent
top: l1 standard
top: l2 standard
top: l3 standard
top: l4 standard
top: l6 standard
这是我的代码:
int main() …
