} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) { NSLog(@"filePah:%@",filePath); } ];
//开始下载 [task resume];
//利用kvo监听下载进度
//利用kvo 通过将当前类的对象设置成观察者(监听者),让当前类观察downloadProgress里面的fractionCompleted属性的变化
//NSKeyValueObservingOptionNew:标记值的变化,这个是新值 //NSKeyValueObservingOptionOld:旧值

//获取 进度变化
float chanagefl = [[object valueForKeyPath:keyPath] floatValue];
//
_progressView.progress = chanagefl; //开始不能体现变化,是因为下载的过程是异步的,不能实时的获取值的变化.所以利用多线程的知识解决问题
[[NSOperationQueue mainQueue] addOperationWithBlock:^{

}];
