Question

如何在主线程下面执行帖子？

  var post:String = "fname=\(addy)&lname=\(fff)&time=\(ff)&action=\(sd_asds)&actionid=add&content=\(d)".stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!

是否可能在主线程上运行帖子会导致内存警告？

Answer 1

为了发送POST请求，您可以使用NSURLConnection类，该类具有发送请求asyncrhonously的方法，这意味着它将执行＆＃34;关闭主线程＆＃34;。

示例：

 var post:String = "fname=\(addy)&lname=\(fff)&time=\(ff)&action=\(sd_asds)&actionid=add&content=\(d)".stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!
 var postURL: NSURL = NSURL(string: post)

let request: NSURLRequest = NSURLRequest(URL:postURL)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue(), completionHandler:{ response, data, error in 
//your code here
 })
