Table View still blank? - ios

Question

I have a problem with my tableview. I'm trying to make a program that downloads job details from my database and lists them. The tableview is still blank, the view is connected to the specific controller and I have checked that the JSON feed and cell identifier are OK. My cell rows are also strange, the row lines continue over the right edge though I have aligned the tableview object correctly. I had similar problems with my previous project but didn't know what was wrong.
Here is a part of the code (Source from: http://codewithchris.com/iphone-app-connect-to-mysql-database/)
JobViewer.m
#interface JobViewer()
{
NSMutableData *_downloadedData;
}
#end
#implementation JobViewer
- (void)downloadItems
{
// Getting json file
NSURL *jsonFileURL = [NSURL URLWithString:#"here is my correct URL"];
//Making request
NSURLRequest *urlRequest = [[NSURLRequest alloc] initWithURL:jsonFileURL];
//Creating NSURLConnection with the request
[NSURLConnection connectionWithRequest:urlRequest delegate:self];
}
#pragma mark NSURLConnectionDataProtocol Methods
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
//Initialize data
_downloadedData = [[NSMutableData alloc] init];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data

//Append the data that was downloaded
[_downloadedData appendData:data];
}
- (void)connectionDidFinishDownloading:(NSURLConnection *)connection
{
//Creating array for the information
NSMutableArray *_jobs = [[NSMutableArray alloc] init];
// Parsing the JSON file
NSError *error;
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:_downloadedData options:NSJSONReadingAllowFragments error:&error];
//Looping through JSON objects and storing them into array
for (int i = 0; i < jsonArray.count; i++)
{
NSDictionary *jsonObject = jsonArray[i];
//Creating a new object and getting data from JSON element
Job *newJob = [[Job alloc] init];
newJob.jobid = jsonObject[#"Job_id"];
newJob.companyid = jsonObject[#"Company_id"];
newJob.customer = jsonObject[#"Customer"];
newJob.phone = jsonObject[#"Phone"];
newJob.email = jsonObject[#"Email"];
newJob.address = jsonObject[#"Address"];
newJob.city = jsonObject[#"City"];
newJob.header = jsonObject[#"Header"];
newJob.notes = jsonObject[#"Notes"];
newJob.date = jsonObject[#"Date"];
newJob.driver = jsonObject[#"Driver"];
//Added question to array
[_jobs addObject:newJob];
}
// Passing the done data and passing items back

{
[self.delegate itemsDownloaded:_jobs];
}
}

Answer 1

You likely need to add "InfoCell" as the reuse identifier in your Storyboard.

Answer 2

Probably your tableView doesn't recognise the cell so you should add the cell at tableView in the storyboard and it is called "InfoCell"
If you don't want to add cell into tableView in the storyboard and you have a xib with your cell. you can call in your viewController this method:
[tableView registerNib:[UINib nibWithNibName:#"IndoCell" bundle:nil] forCellReuseIdentifier:#"IndoCell"];
that if your nib is called "IndoCell.xib"
