NSURLSession是IOS8開始出來的, 在ios開發(fā)中使用NSURLConnection后xcode會(huì)提示使用ios8開始使用Session,下面我來簡(jiǎn)單介紹下我使用的經(jīng)驗(yàn)

1使用NSURLSession

objective-c

NSURLSession *session = [[NSURLSession alloc] init];

NSURLSession *session = NSURLSessionDataTask *task = [[NSURLSession alloc] init];
[session dataTaskWithRequest:request completionHandler:^(NSData*data,NSURLResponse *response,NSError *error){
        NSLog(NSString(data: data, encoding: NSUTF8StringEncoding));
}];
[task resume];

swift

//聲明
let session = NSURLSession.sharedSession()
let task:NSURLSessionDataTask = session.dataTaskWithRequest(request) { (data, response, error) -> Void in
        print(NSString(data: data, encoding: NSUTF8StringEncoding))
}
task.resume()

下面我們自己來封裝一個(gè)簡(jiǎn)單的Request方法

objective-c

博主犯懶了OC還沒寫

swift

func RequestURL() -> Void {
        //訪問網(wǎng)址
        let request:NSMutableURLRequest = NSMutableURLRequest(URL: NSURL(string: "http")!)
        //設(shè)置超時(shí)時(shí)間
        request.timeoutInterval = 60
        //設(shè)置訪問類型
        request.HTTPMethod = "GET/POST"
        //可以設(shè)置自己請(qǐng)求頭參數(shù)
        //request.addValue("value", forHTTPHeaderField: "key")
        request.HTTPBody = "內(nèi)容".dataUsingEncoding(NSUTF8StringEncoding)
        let session = NSURLSession.sharedSession()
        let task:NSURLSessionDataTask = session.dataTaskWithRequest(request) { (data, response, error) -> Void in
            print(NSString(data: data!, encoding: NSUTF8StringEncoding))
        }
        task.resume()
    }


//將閉包當(dāng)做參數(shù)傳遞
func RequestURL(URL URL:String,method:String,callback:(data:NSData,response:NSURLResponse,error:NSError) -> Void) -> Void {
        //訪問網(wǎng)址
        let request:NSMutableURLRequest = NSMutableURLRequest(URL: NSURL(string: URL)!)
        //設(shè)置超時(shí)時(shí)間
        request.timeoutInterval = 60
        //設(shè)置訪問類型
        request.HTTPMethod = method //"GET/POST"
        //可以設(shè)置自己請(qǐng)求頭參數(shù)
        //request.addValue("value", forHTTPHeaderField: "key")
        request.HTTPBody = "內(nèi)容".dataUsingEncoding(NSUTF8StringEncoding)
        let session = NSURLSession.sharedSession()
        let task:NSURLSessionDataTask = session.dataTaskWithRequest(request) { (data, response, error) -> Void in
            callback(data:data!,response:response!,error:error!)
        }
        task.resume()
    }
