Is it possible to get cities polygonal boundaries like in Google Maps?

阅读更多关于 Is it possible to get cities polygonal boundaries like in Google Maps?

问题 I would like to have the possibility to tell if a GPS location is in an inhabited or uninhabited zone. I have tried some reverse geocoding services out there, but all of them proved useless, because they select the nearest address possible. (I understand why this should be so, it is useful for the purpose of reverse geocoding) I have noticed in Google Maps , when I search for a city, their boundaries are selected in red dotted well defined line. I would love it to use this, or something

Why is the MKMapView's userLocation property rubbish … for a while?

阅读更多关于 Why is the MKMapView's userLocation property rubbish … for a while?

问题 I have a Map View defined in IB and it is set to show the user location. In my app, in -viewDidAppear , I query self.mapView.userLocation.location.coordinate and it comes back with insane values such as: latitude : 4.8194501961644877e-49 longitude : 2.2993313035571993e-59 However, the next time -viewDidAppear is called (after I've simply moved to another tabbed view and then back to this one) the userLocation property holds exactly the correct values for my current location. It seems that at

问题 I looked at this Q&A here: GoogleApiClient is throwing "GoogleApiClient is not connected yet" AFTER onConnected function getting called As it seemed to be similar to what I was experiencing but, it's not. The issue with that user was that they were declaring their api client in the onStart() method, I create mine in the onCreate() method like suggested by the answer. I am still however, getting the same error. Here is the code I have for these three methods: protected void onCreate(Bundle

Question about setTimeout that I need answer to

阅读更多关于 Question about setTimeout that I need answer to

问题 So we all know setTimeout waits a certain amount of time before executing something. My question is, does it wait for the above code to finish executing first, before waiting a second to execute something else, or does it just wait for a second, and whether or not the above code has finished executing, it executes the rest of the code anyways? if (1 == 1) { //huge chunk of code } //end of if (1 == 1) var theTime = 1000; var timeout = setTimeout("location.reload(true);", theTime); function

控制Nginx上传文件大小限制(请求报文过大)

阅读更多关于控制Nginx上传文件大小限制(请求报文过大)

在nginx使用过程中，上传文件的过程中，通常需要设置nginx报文大小限制。避免出现 413 Request Entity Too Large 。于是奇葩的问题被我们遇到了，详细配置请参考下面。我们的问题是，无论client_max_body_size设置在哪里，nginx －s reload后，依然一直报413.多次尝试reload，始终无效。最终决定kill 进程，restart，终于好了。设置如下： Syntax: client_max_body_size size ; Default: client_max_body_size 1m; Context: http , server , location 可以选择在http{ }中设置：client_max_body_size 20m; 也可以选择在server{ }中设置：client_max_body_size 20m; 还可以选择在location{ }中设置：client_max_body_size 20m; 三者到区别是： http{} 中控制着所有nginx收到的请求。而报文大小限制设置在server｛｝中，则控制该server收到的请求报文大小，同理，如果配置在location中，则报文大小限制，只对匹配了location 路由规则的请求生效。来源： CSDN 作者： jmlqqs 链接： https:/

PHP How to header-location to a page in a parent directory?

阅读更多关于 PHP How to header-location to a page in a parent directory?

问题 I have a first.php page with header("Location: script/script1.php") and script1.php has another header("Location: first.php") but it sends me obviously to /script/first.php . Is there a way to redirect it to <root>/first.php instead of <root>/script/first.php ? 回答1: have a try with this: header("Location: ../first.php") or use an absolute path or url instead. Explanation: .. is the unix/linux expression used for 'parent directory'. The Internet is unix land, so that rules applies there too.
