Question

我已经提出了api请求，要求从我的后端服务中获取一些细节：

我想解雇我当前的视图控制器，并通过后端的网址启动新的网页：

NSDictionary *parameters = @{@"X-Service-Code" : @"PP", @"Accept" : @"application/json", @"Content-Type" : @"application/json"};
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    [manager GET:url1 parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {


        NSMutableArray *jsonArray = [[NSMutableArray alloc]init];
        jsonArray = [NSJSONSerialization JSONObjectWithData: responseObject options:NSJSONReadingMutableContainers error:nil];


        [self dismissViewControllerAnimated:YES completion:nil];


        NSString *urlAddress = [[jsonArray objectAtIndex:10]valueForKey:@"value"];
        [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlAddress]]];


    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

webview正在后台启动，但视图控制器不会被解雇。有什么建议吗？

Answer 1

需要在主线程上调用

dismissViewControllerAnimated：

dispatch_async(dispatch_get_main_queue(), ^{
    [self dismissViewControllerAnimated:YES completion:nil];
});

Answer 2

尝试在主线程上运行dismiss代码：

dispatch_async(dispatch_get_main_queue(), ^{
    [self dismissViewControllerAnimated:YES completion:nil];
});

关闭app并在appstart上启动webview
