requestLocationUpdates() in separate Thread

阅读更多关于 requestLocationUpdates() in separate Thread

I need requestLocationUpdates() to be in a separate Thread, in order to not have it blocking the rest of my application (it will run most of the time). What is the best way to do it? When you call requestLocationUpdates() this just indicates that you want to be called back when the user's location changes. This call doesn't take a significant amount of time and can be made on the main thread. When the user's location changes (and based on the criteria you pass to requestLocationUpdates() ) your listener will be called back via onLocationChanged() or notified via Intent (depending on which

Hide MKUserLocation when MKMapView showsUserLocation == YES

阅读更多关于 Hide MKUserLocation when MKMapView showsUserLocation == YES

After setting mapView.showsUserLocation to true, is it possible to receive location updates without showing the MKUserLocation bubble? Returning nil in mapView:viewForAnnotation: simply shows the bubble, and returning any other kind of annotation shows an annotation, which I don't want. You can hide the user location's view in the didAddAnnotationViews delegate method: -(void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views { MKAnnotationView *ulv = [mapView viewForAnnotation:mapView.userLocation]; ulv.hidden = YES; } Swift 3: func mapView(_ mapView: MKMapView, didAdd views:

nginx静态资源配置（转发）

阅读更多关于 nginx静态资源配置（转发）

传统的web项目，一般都将静态资源存放在 webroot的目录下，这样做很方便获取静态资源，但是如果说web项目很大，用户很多，静态资源也很多时，服务器的性能或许就会很低下了。这种情况下一般都会需要一个静态资源的服务器。搭建nginx服务器首先得安装nginx服务，关于nginx服务的安装可以参考我的另一篇博客《nginx服务安装》这里直接介绍静态服务器的配置进入nginx安装目录的conf目录下，修改nginx.conf文件，在一个server{}中添加一个location 部分配置代码如下 root@ubuntu:/usr/local/nginx/conf# vi nginx.conf server { listen 80; server_name localhost; location / { root html; index index.html index.htm; } location /image/ { root /usr/local/myImage/; autoindex on; } } 从上面的配置可以看出来端口为80，server_name为localhost（写ip地址也可以） location /image/ { root /usr/local/myImage/; autoindex on; } 这个配置表示输入 localhost:80

前端必须掌握的 nginx 技能(2)

阅读更多关于前端必须掌握的 nginx 技能(2)

概述作为一个前端，我觉得必须要学会使用 nginx 干下面几件事：代理静态资源设置反向代理（添加https）设置缓存设置 log 部署 smtp 服务设置 redis 缓存（选）下面我按照这个节奏一一研究一遍，把心得记录下来，供以后开发时参考，相信对其他人也有用。参考资料：前端工程师学习 Nginx 入门篇设置反向代理为什么叫反向代理？因为一般的代理是代理客户端，而如果我们要代理服务器的话，就好像反向一样，所以叫反向代理。所以我们把代理服务器的代理都叫反向代理。 nginx 里面设置反向代理只需要使用 proxy_pass 指令就可以了。具体文档在这里 Module ngx_http_proxy_module 。示例如下： events { # worker_connections 1024; ## Default: 1024 } http { server { listen 8767; server_name 192.168.2.32; location / { root /Users/zhouyang/Documents/tencent/test/local-nginx; } location /baidu { proxy_pass http://www.baidu.com; } } } 我们在 bash 执行如下命令，然后打开 192.168.2.32
