AngularJS - Best way to update $route parameter

阅读更多关于 AngularJS - Best way to update $route parameter

问题 I have several routes that are different, but contain similar parameters. Example: when '/user/:accountId/charts/:chartType', controller:ChartsController when '/manager/:accountId/charts/:chartType', controller:ChartsController when '/whatever/pathy/paththingy/charts/:chartType', controller:ChartsController Notice all three views use the same Charts Controller to control the view. Its a fairly generic controller but it needs toggle between available chartTypes... while keeping the rest of the

iOS Region Monitoring in Background Mode

阅读更多关于 iOS Region Monitoring in Background Mode

问题 I am using Region Monitoring in my app and I faced a question that I couldn't find any answer to it. How does region monitoring work in background mode? According to Location Awareness PG: Every time the user’s current location crosses a boundary region, the system generates an appropriate region event for your application. If your application is already running, these events go directly to the delegates of any current location manager objects. If your application is not running, the system

Android Gps Routing system

阅读更多关于 Android Gps Routing system

I'm developing an android application that would locate the user(assuming that the user is on the road) and the app will create the shortest route for the user to take to be able to go to the users chosen destination. Locating the user isn't the question since there's an API for that here: http://www.vogella.com/articles/AndroidLocationAPI/article.html so here's the catch. The roads ,intersections and their distances can be mapped or declared via variables in the code but my problem is that the GPS APIs i found so far would only return a longitude and latitude and not the road names or the

This is how I add my geofences: public void setGeofenceRequest(Location location) { if (geofences == null) { geofences = new ArrayList<Geofence>(); } geofences.add(new Geofence.Builder() .setRequestId("3") .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_EXIT) .setCircularRegion( location.getLatitude(), location.getLongitude(), PSLocationService.getInstance(context).kPSGeofencingDistanceMedium) .setExpirationDuration(Geofence.NEVER_EXPIRE) .build()); Intent intent = new Intent(context, ReceiveTransitionsBroadcastReceiver.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent,

programmatically erase android browser cache, history, etc. with root

阅读更多关于 programmatically erase android browser cache, history, etc. with root

I have an android tablet that is locked down (users will only be able to use standard issue android browser), so all the temporary internet stuff should be in the same place. Assuming I am able to root the device sometime here soon, I would like to be able to wipe out (1) cookies,(2) temp internet files,(3) history,(4) form data,(5) location access info,(6) passwords, (7) cache. I think I can knock out most of these by erasing: /data/data/com.android.browser/cache The cookies appear to be in a database. I'm not sure if I can just delete it /data/data/com.android.browser/databases/webview.db

Android Context without being in an activity? And other activity-less programming?

阅读更多关于 Android Context without being in an activity? And other activity-less programming?

问题 I'll try really hard to turn this into one comprehensive question: I'm writing a method to get a String that contains the name of an Android device's city, as determined by the LocationManager and getLastKnownLocation() and all that. Then I realized I'd need to do the same thing again in another activity, so why not just make an entirely separate class ( LocationFinder ) that I could use across my program, instead of writing duplicate code everywhere? But I've run into problems that confuses

onload：在加载的时候因为网页代码是从上到下执行的，所以我们有些对网页内容的操作要先加载出网页内容后再执行script的内容，这个时候如果没有onload我们只能写在这些内容的后面，但是有了load就不一样了但是load也是有缺点的，就是load要等到页面中全部东西，包括音频视频等，才会执行load中的内容，这个时候就会使其变得慢！ onunload：在你关闭网页的时候网页就消失了，所以也不会显示出来，但是在刷新的时候相当于网页的卸载和重新加载，所以此时可以看看出来，因此这个函数中主要写一些网页关闭后的清除工作 settimeout：有两个参数，第一个是函数，可以写匿名函数，第二个是时间，以毫秒为单位，在达到这个事件的时候就会执行这个匿名函数返回值：这个函数的返回值是一个数字，通过这个数字可以找到这个定时器清除定时器函数：cleartimeout 另一个定时器（间隔一段时间做一个事情，上一个是到了什么时间做那个事情（只会做一个），这个能做多次）：setInterval：其参数和上一个一样，也是两个参数清除此定时器，此函数的返回值也是一个标识倒计时案例： 1970年1月1日0、0、0 Math.floor（）：向下取整 new Date(年-月-日-时-分-秒) 其中时分秒不写默认为0 但是这个定时器是要等一定时间才执行

nginx rewrite 规则详解

阅读更多关于 nginx rewrite 规则详解

Rewrite简介 rewrite功能就是，使用nginx提供的全局变量或自己设置的变量，结合正则表达式和标志位实现url重写以及重定向。 rewrite只能放在server{},location{},if{}中，并且只能对域名后边的除去传递的参数外的字符串起作用。表明看rewrite和location功能有点像，都能实现跳转，主要区别在于rewrite是在同一域名内更改获取资源的路径，而location是对一类路径做控制访问或反向代理，可以proxy_pass到其机器。很多情况下rewrite也会写在location里，它们的执行顺序：执行server块的rewrite指令执行location匹配执行选定的location中的rewrite指令如果其中某步URI被重写，则重新循环执行1-3，直到找到真实存在的文件；循环超过10次，则返回500 Internal Server Error错误。 Flag 标志位 last : 相当于Apache的[L]标记，表示完成当前的rewrite规则 break : 停止执行当前虚拟主机的后续rewrite指令集 redirect : 返回302临时重定向，地址栏会显示跳转后的地址 permanent : 返回301永久重定向，地址栏会显示跳转后的地址因为301和302不能简单的只返回状态码，还必须有重定向的URL

Will the kCLLocationAccuracyBestForNavigation setting in Core Location Improve Location Services for Walking Around?

阅读更多关于 Will the kCLLocationAccuracyBestForNavigation setting in Core Location Improve Location Services for Walking Around?

问题 I have an application that needs to keep very precise data about where a user is walking. Will having kCLLocationAccuracyBestForNavigation turned on as opposed to kCLLocationAccuracyBest gain me anything in this situation? Thanks. 回答1: kCLLocationAccuracyBestForNavigation is better for what you want to achieve as opposed to kCLLocationAccuracyBest. the only reason not to pick the BestForNavigation is the support of devices with iOS<4. As a side note, kCLLocationAccuracyBestForNavigation will
