How to get Country name by given Postal Code (ZIP) on iOS SDK

由 我是研究僧i 提交于 2019-12-10 22:09:03
问题 Is it possible to get the country name by giving the postal code of the user? I looked at the Core Location Framework, but it doesn't look to work the other way around by given the Postal Code and finding the Country name. The Core Location framework (CoreLocation.framework) provides location and heading information to apps. For location information, the framework uses the onboard GPS, cell, or Wi-Fi radios to find the user’s current longitude and latitude. I hope there is a class on iOS SDK,

Mapsforge analog for iphone

由 会有一股神秘感。 提交于 2019-12-10 21:53:42
问题 I need some framework for my iPhone app, which is using maps. Now these maps are raster images and I'd like to optimize my app by doing vector maps instead. I know that my colleagues from Android development had used Mapsforge framework for this purposes. Is there any analog of this library for iPhone? I need framework that could quickly render vector maps using hardware acceleration, caching maps, offline rendering and (optinal) be cross-platform. Any suggestions? Thanks! 回答1: Have a look at

Google Maps event listeners not working properly in a Javascript 'for' loop

由 筅森魡賤 提交于 2019-12-10 20:59:32
问题 I'm trying to set up a Google map instance where some content is dynamically generated for a set of points. Right now, I'm using a for loop to loop through any number of latitude and longitude values and create markers are those points on the map. I'm trying to add info windows that correspond to each of these markers and have them pop up when you click the markers. However, I'm having a little bit of trouble. It looks like my for loop that creates basically everything is working without fail

Google maps tiles doesn't load

由 浪子不回头ぞ 提交于 2019-12-10 19:45:33
问题 I'm developing a simple Google Maps app for Android. I'm using Eclipse and an Android Virtual Device. When running the app, no tiles are shown, and I get the message "Couldn't get connection factory client". I've read and looks like it is a bug, but some people say they got their apps working. I've tried using API 1.6, 2.1, 2.2 over my virtual device (2.2) and none of them work. I got my API key from the MD5 obtained from the debug.keystore. How can I solve the problem? I just found people

mapping location to a time zone

由 别说谁变了你拦得住时间么 提交于 2019-12-10 19:02:05
问题 I need to get the time zone for a given address/location. Assume that the address/location can be reverse geocoded (using google) to a lat/lng if necessary. This means that I may not have a zip code. I was really hoping that google provided some kind of API for this, but it seems that they don't. At a minimum you can google search for "time in washington, dc" and get the time/TZ -- but then I'd have to screen scrape that which is not fun :( I know there are databases available that map

Google Maps API v3: Turning user input coordinates to latlng?

由 别来无恙 提交于 2019-12-10 17:05:33
问题 I'm new with Google Maps. I'm trying to turn coordinates a user inputs to move a marker I have on my map to those coordinates. For instance, if the user inputs 50.75, 74.1 the marker will pan to that coordinate. Unfortunately, I couldn't get it to work. Here's my function: function moveMarker() { var Markerloc = document.getElementById("Markerloc").value; var newLatlng = new google.maps.LatLng(Markerloc); marker.setPosition(newLatLng) } Here's my HTML code: <input type="text" id= "Markerloc"

问题 I have my application with a map. In this map i put a marker in the current location of the device.
