我有以下代码：
let urlPath:String = apiURL + apiVersion + url + "?api_key=" + apiKey
let url = NSURL(string: urlPath)
let session = NSURLSession.sharedSession()
println(url!)
let task = session.dataTaskWithURL(url!,completionHandler: {(data,reponse,error) in
println("Task completed")
// rest of the function...
})
永远不会调用completionHandler函数.我尝试在浏览器中调用URL,它运行正常.我试过另一个URL,它仍然无法正常工作.我检查了我的ios模拟器可以连接到互联网,它确实.
任务永远不会完成,因为它永远不会开始.您必须使用resume()方法手动启动数据任务.
let urlPath = apiURL + apiVersion + url + "?api_key=" + apiKey
let url = NSURL(string: urlPath)!
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithURL(url) { data,response,error in
print("Task completed")
// rest of the function...
}
task.resume()
