问题说明
如何获得AFHTTPRequest的进度？我试过在网上搜索。
我正在使用：
How can I get the progress of an AFHTTPRequest? I've tried searching all over the net.
I am using:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = @{@"gameId" : datas[0], @"p1": datas[1], @"p2":datas[2], @"turn":datas[3] };
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:@"http://localhost/thepath/isprivate/thefile.php"
parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
是否有可用于访问AFNetworking 2.0 HTTP POST进度的属性或方法？
Is there like, a property or method I can use to access the progress of an AFNetworking 2.0 HTTP POST?

您可以使用以下方法
- (NSURLSessionUploadTask *)uploadTaskWithRequest:(NSURLRequest *)request
fromData:(NSData *)bodyData
progress:(NSProgress * __autoreleasing *)progress
completionHandler:(void (^)(NSURLResponse *response, id responseObject, NSError *error))completionHandler
AFHTTPSessionManager class。
更新：
通常你更喜欢使用KVO获取上传值。所以应该使用以下内容：
Usually you will prefer to use KVO to get uploading values. So something like following should be used:
static void * kDGProgressChanged = &kDGProgressChanged;
...
[progress addObserver:self
forKeyPath:@"fractionCompleted"
options:NSKeyValueObservingOptionNew
context:kDGProgressChanged];
...
- (void)observeValueForKeyPath:(NSString *)keyPath
ofObject:(id)object
change:(__unused NSDictionary *)change
context:(void *)context
{
if (kDGProgressChanged == context) {
dispatch_async(dispatch_get_main_queue(), ^{
[self updateProgressInfo];
});
}
}
