Multi-Threaded Refresh

JSON parsing in the network request;

1. Get access Path

NSString *[email protected] "HTTP://1.STUDYIOS.SINAAPP.COM/GYXY.PHP?A=QQ";

2. Encapsulating URLs

Nsurl *url=[nsurl Urlwithstring:path];

3. Create a request command

Nsurlrequest *request=[nsurlrequest Requestwithurl:url];

4. Create a Session object by using a singleton method

Nsurlsession *session=[nsurlsession Sharedsession];

5. Execute Session task get data object through request

Nsurlsessiondatatask *task=[session datataskwithrequest:request completionhandler:^ (NSData * _Nullable data, Nsurlresponse * _nullable response, Nserror * _nullable error) {

6. JSON parsing

Nsarray *arrjson=[nsjsonserialization jsonobjectwithdata:data options:nsjsonreadingmutableleaves Error:&error] ;

NSLog (@ "%@", Arrjson);

}];

7, the real implementation of the task

[Task resume];

Get set Arrjson;

To put the set on the TableView will not show, this is the Teibleview on the multi-threaded request needs to use the main thread to refresh the data

After modification:

1. Get access Path

NSString *[email protected] "HTTP://1.STUDYIOS.SINAAPP.COM/GYXY.PHP?A=QQ";

2. Encapsulating URLs

Nsurl *url=[nsurl Urlwithstring:path];

3. Create a request command

Nsurlrequest *request=[nsurlrequest Requestwithurl:url];

4. Create a Session object by using a singleton method

Nsurlsession *session=[nsurlsession Sharedsession];

5. Execute Session task get data object through request

Nsurlsessiondatatask *task=[session datataskwithrequest:request completionhandler:^ (NSData * _Nullable data, Nsurlresponse * _nullable response, Nserror * _nullable error) {

6. JSON parsing

Nsarray *arrjson=[nsjsonserialization jsonobjectwithdata:data options:nsjsonreadingmutableleaves Error:&error] ;

NSLog (@ "%@", Arrjson);

Dispatch_async (Dispatch_get_main_queue (), ^{[self.table reloaddata]; });

}];

7, the real implementation of the task

[Task resume];

This will show up on the TableView.
