Question

我同时有一些请求，我想处理它，直到它们全部完成。以下是要求：

[self getProfileData];
[self checkNewSystemMessage];
[self checkChatMessage];

在getProfileData看起来像：

AFHTTPRequestOperationManager* manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval = TIMEOUT_INTERVAL;
NSString * portNumber = [[NSUserDefaults standardUserDefaults] objectForKey:@"portNumber"];

[manager GET:URL_ADDRESS(portNumber,@"JsonEntryManager") parameters:dic success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"%@",responseObject);
    //Do something...
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    [self performSelector:@selector(getProfileData) withObject:nil afterDelay:REQUEST_AGAIN_TIME];
}];

和其他人是一样的。当他们全部完成时我想做点什么。我想的唯一方法是逐个请求它们。显然这是一个愚蠢的想法。那我怎么知道结束时间呢？

Answer 1

在开始任何请求初始化计数器之前：

int counter = 0;

并在每个请求的成功块中执行

counter++;
if(counter==3)
{
    //Do what you need to do when all the request is completed.
    //Make some method for this.
}

我也试图弄清楚这一点，但是现在成功为我工作的是检查{strong}成功中AFHTTPRequestOperationManager的OperationQueue内部的操作次数阻止：

[manager GET:URL_ADDRESS(portNumber,@"JsonEntryManager") parameters:dic success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"%@",responseObject);

if ([weakSelf.manager.operationQueue operationCount] == 0) {
       //Do something here when all the operations are done.
    }

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    [self performSelector:@selector(getProfileData) withObject:nil afterDelay:REQUEST_AGAIN_TIME];
}];

如何在多请求中使用AFNetworking？
