我有一個UIWebView顯示一個只有一個地圖上的網站。我想打開UIWebView並直接到我目前的位置。任何幫助將不勝感激!如何在我的當前位置打開UIWebView?
感謝
下面是我的一些代碼 -
ViewController.h:
#import <UIKit/UIKit.h>
#import <StoreKit/StoreKit.h>
#import <CoreMotion/CoreMotion.h>
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
@interface ViewController : UIViewController <UIWebViewDelegate, MKMapViewDelegate, CLLocationManagerDelegate>
@property (strong, nonatomic) IBOutlet UIWebView *viewWeb;
@property (nonatomic, strong) CLLocationManager *locationManager;
@property (nonatomic, strong) CLLocation *currentLocation;
@end
ViewController.m:
#import "ViewController.h"
@interface ViewController() <UITextViewDelegate>
@end
@implementation ViewController
@synthesize viewWeb;
- (void)viewDidLoad
{
[super viewDidLoad];
// Request Intel Site
NSString *fullURL = @「http://www.websitewithmap.com/」;
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
viewWeb.scalesPageToFit = YES;
viewWeb.scrollView.bounces = NO;
[viewWeb loadRequest:requestObj];
}
@end
我的JavaScript代碼:
// LOCATION HANDLING /////////////////////////////////////////////////
// i.e. setting initial position and storing new position after moving
// retrieves current position from map and stores it cookies
window.storeMapPosition = function() {
var m = window.map.getCenter();
if(m['lat'] >= -90 && m['lat'] <= 90)
writeCookie('gps.intelmap.lat', m['lat']);
if(m['lng'] >= -180 && m['lng'] <= 180)
writeCookie('gps.intelmap.lng', m['lng']);
writeCookie('gps.intelmap.zoom', window.map.getZoom());
}
// either retrieves the last shown position from a cookie, from the
// URL or if neither is present, via Geolocation. If that fails, it
// returns a map that shows the whole world.
window.getPosition = function() {
if(getURLParam('latE6') && getURLParam('lngE6')) {
console.log("mappos: reading email URL params");
var lat = parseInt(getURLParam('latE6'))/1E6 || 0.0;
var lng = parseInt(getURLParam('lngE6'))/1E6 || 0.0;
var z = parseInt(getURLParam('z')) || 17;
return {center: new L.LatLng(lat, lng), zoom: z};
}
if(getURLParam('ll')) {
console.log("mappos: reading stock Intel URL params");
var lat = parseFloat(getURLParam('ll').split(",")[0]) || 0.0;
var lng = parseFloat(getURLParam('ll').split(",")[1]) || 0.0;
var z = parseInt(getURLParam('z')) || 17;
return {center: new L.LatLng(lat, lng), zoom: z};
}
if(readCookie('gps.intelmap.lat') && readCookie('gps.intelmap.lng')) {
console.log("mappos: reading cookies");
var lat = parseFloat(readCookie('gps.intelmap.lat')) || 0.0;
var lng = parseFloat(readCookie('gps.intelmap.lng')) || 0.0;
var z = parseInt(readCookie('gps.intelmap.zoom')) || 17;
if(lat < -90 || lat > 90) lat = 0.0;
if(lng < -180 || lng > 180) lng = 0.0;
return {center: new L.LatLng(lat, lng), zoom: z};
}
setTimeout("window.map.locate({setView : true});", 50);
return {center: new L.LatLng(0.0, 0.0), zoom: 1};
}

這個帶地圖的網站是否有某種可以通過它的api座標? –
我剛剛對我的問題進行了編輯,顯示我的JavaScript代碼的一部分,我相信該位置被稱爲。我使用 - (void)webViewDidFinishLoad:(UIWebView *)viewWeb NSLog(@「Got here!」); [_viewWeb stringByEvaluatingJavaScriptFromString:@「window.getPosition = function()」]; } – Creagen
我想我現在對你想要做的事感到困惑。您是否無法獲取用戶在設備上的位置,或者您是否無法將該位置的座標傳遞給您的JavaScript,或者JavaScript無法使用傳遞給它的數據? –
