NSURLConnection 延迟 5 秒 [英] NSURLConnection 5 seconds delay

问题描述

我有以下代码向我的 api 发出请求:

i have the following code to make requests to my api:

-(void)makeApiCall:(NSString *)function params:(NSDictionary *)params notificationName:(NSString *)notificationName
{    
NSURL *url = [NSURL URLWithString:kBaseUrl];

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
httpClient.parameterEncoding = AFFormURLParameterEncoding;

NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:[NSString stringWithFormat:@"%@/%@",kApiBaseUrl,function] parameters:params];


NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    NSLog(@"complete");
//..My code        
}];    
}

我的问题是，在 NSLog(@"complete") 之后，应用程序冻结了 5 秒.我该如何解决?

My problem is that, after the NSLog(@"complete"), the app is frozen for 5 seconds.. How can i fix that?

谢谢.

推荐答案

sendAsynchronousRequest 的 queue 参数是完成处理程序块被分派.如果您在完成中进行任何 UI 更新处理程序，那么您可能应该使用

The queue parameter of sendAsynchronousRequest is the queue on which the completion handler block is dispatched. If you do any UI updates in the completion handler then you probably should call the method with

queue:[NSOperationQueue mainQueue]
