objective-c - URL applicationWillTerminate Objective-C

Question

我一直在尝试在 de applicationWillTerminate 事件中执行或请求一个 url，但是当我这样做时，其他功能，如:

- (NSURLRequest *)connection:(NSURLConnection *)connection
             willSendRequest:(NSURLRequest *)request            redirectResponse:(NSURLResponse *)redirectResponse {
  [baseURL autorelease];
  baseURL = [[request URL] retain];
  return request;
}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
  [responseData setLength:0];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
  [responseData appendData:data];
}

它们没有被执行，我猜是因为最后执行的函数或事件是 applicationWillTerminate。有没有办法达到或做到这一点。

我昨天遇到了同样的问题，并使用下面的代码片段解决了它:

NSURLResponse* response = nil;
NSString* requestUrlString = <your URL>;
NSMutableURLRequest *syncRequest  = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:requestUrlString] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30];
[NSURLConnection sendSynchronousRequest:syncRequest returningResponse:&response error:nil];
