我创建了一个带有html的webview来加载当前用户的位置。
这是使用的结构：
webview.m - 加载index.html
index.html - 显示数据
info.plist - NSLocationWhenInUseUsageDescription＆amp;添加了NSLocationAlwaysUsageDescription
以下是两种情况：
1）如果我在Webview中加载Google地图 - 它不会加载我当前的位置。旋转器只是旋转并显示世界地图。
2）在index.html中，我添加了加载当前位置经度和纬度的代码。在笔记本电脑的浏览器（不是xcode）它显示我的位置，如果我在xcode中打开index.html它没有显示我。
可能需要添加一些内容才能让应用获取您的位置，例如在浏览器上它要求获得位置许可。在应用程序中，它没有问我这个。
这是代码： webview.m
#import "Webview.h"
@interface Webview ()
@end
@implementation Webview
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
NSString *urlAddress= [[NSBundle mainBundle] pathForResource:@"demos/index" ofType:@"html"];
NSURL *url = [NSURL fileURLWithPath: urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL: url];
[_webView setDelegate:self];
_webView.scrollView.delegate = self;
_webView.scrollView.scrollEnabled = true;
_webView.scrollView.bounces = NO;
[_webView loadRequest:requestObj];
}
-(void)scrollViewDidScroll:(UIScrollView *)scrollView{
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
的index.html

问题：如何让我的应用程序询问位置权限？或直接加载位置？

问题：如何让我的应用程序询问位置权限？或直接加载位置？
首先，这里有一个SO thread可能会提供使用UIWebView显示地图的解决方案。
现在关于iOS地图中的权限：
尝试使用locationManager(_:didChangeAuthorizationStatus:)启用权限。这意味着您在使用应用程序时授予用户权限。
extension MapViewController: CLLocationManagerDelegate {
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == .AuthorizedWhenInUse {
locationManager.startUpdatingLocation()
mapView.myLocationEnabled = true
mapView.settings.myLocationButton = true
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
if let location = locations.first {
mapView.camera = GMSCameraPosition(target: location.coordinate, zoom: 15, bearing: 0, viewingAngle: 0)
locationManager.stopUpdatingLocation()
}
}
}
