[[self GETManage] GET:ready_exchange_list_URL parameters:params progress:^(NSProgress * _Nonnull downloadProgress) {
//不起作用
[dataTableView endLoad];
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable
progress是进程，一般来讲是用不上的，这里面并不是网络一回来的就触发的，所以不能在这里做 [dataTableView endLoad];
不过值得一提的是，
项目一般要对网络接口统一处理
NSURLSessionTask *task = [[GSNetwork shareManager].afHTTPSessionManager GET:basicUrlString parameters:[GSNetworkAssist addCommonParameters:mutableParameters] progress:
^(NSProgress * _Nonnull downloadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
[self handleResponseWithHandler:responseHandler jsonResult:responseObject task:task];
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[self handleResponseWithHandler:responseHandler jsonResult:nil task:task];
}];
return task;
+ (void)handleResponseWithHandler:(GSNetworkResponseHandler)handler
jsonResult:(NSDictionary *)jsonResult
task:(NSURLSessionTask *)task {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSDictionary *afterCheckResult = [GSNetworkAssist checkResult:jsonResult response:task.response];
if (handler) {
GSNetworkResponse *r = [[GSNetworkResponse alloc] initWithJsonResult:afterCheckResult response:task.response];
handler(r);
}
});
}
这就有点屌了，我之前一直以为只能在单层的block里面回调触发，原来也可在block的block里面触发。牛逼
