Question

当我使用此代码时，它会无限次下载。它不会停止下载。有谁知道这是为什么？

 NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"http://gps.com/2.js"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];

NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
    NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
    // Save this following url to load the file
    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
    NSLog(@"File downloaded to: %@", filePath);
}];
[downloadTask resume];
NSString *javaScript = [NSString stringWithContentsOfURL:URL encoding:NSUTF8StringEncoding error: nil];

[webView stringByEvaluatingJavaScriptFromString:javaScript];

使用此代码时也遇到同样的问题：

NSString *jsString = [NSString stringWithContentsOfURL:[[NSBundle mainBundle] URLForResource:@"PrivacyView" withExtension:@"js"] encoding:NSUTF8StringEncoding error:nil];
[_viewWeb stringByEvaluatingJavaScriptFromString:jsString];
NSLog(@"Way out of whack :(");

我发誓，这是我尝试加载javascript文件时的样子：

我的意思是看它的运行次数。它只是一直被召唤，永远不会停止。

如何阻止此下载任务无法控制地运行？
