ASIHTTP - tableView - CSV

[pleasehelp]

Hello guys,

firstable i want to say is that i´m new here and the forum is the best place i have seen for iphone development.

My configuration: Tab Bar with tableView -> klick on row -> detailview

My problem: i make a request with asihttp. so far so good. i get a response

like:
name;tel;email

Hans Mustermann;0123/45678;info@yourdomain.com
Harry the second;98765/12345;my@email.com

in moment i handle the response like:

NSArray *cusNameDataArray = nil;
cusNameDataArray = [[response componentsSeparatedByString:@"\n"]retain];
self.cusNameDataArray =[[NSMutableArray alloc] initWithArray:cusNameDataArray];
[cusNameDataArray release];

and in:

-(UITableViewCell *)tableViewUITableView *)cusTableView cellForRowAtIndexPathNSIndexPath *)indexPath {

static NSString *identifier = @"Cell";

UITableViewCell *cell = [self.cusTableView dequeueReusableCellWithIdentifier:identifier];
if(cell == nil)
//cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:identifier] autorelease];
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:identifier] autorelease];


// Set up the cell...
cell.textLabel.font = [UIFont fontWithName:@"Verdana" size:12];
cell.textLabel.text = here i want the name
cell.detailTextLabel.font = [UIFont fontWithName:@"Verdana" size:10];
cell.detailTextLabel.text = here i want the email and tel;

return cell;
}

you can see that i just want the name in cell.textLabel.text and in cell.detailTextLabel.text the email and telefon

can somebody help me an give me an example? i waste so much time for this solution but nothing found.

One option would be to do further parsing of your curNameDataArray. After your call to componentsSeparatedByString, your array contains one entry per line of the response.

You could then iterate through every string in that array, and separate the string into further strings by separating based on ';'. This would break the string into an array containing 3 entries - the name, phone number, and e-mail address.

Alloc your curNameDataArray and add each broken up array to it, so you'll end up with an array of arrays. The code would look something like:

// Build an array of each individual line
NSArray *tempArray = [response componentsSeparatedByString:@"\n"];
// Allocate my customer array
self.cusNameDataArray =[[NSMutableArray alloc] init];

// Iterate over ever line and break it up into its components
for (int i=0; i<[tempArray count]; i++)
{
  NSString *line = [tempArray objectAtIndex:i];
  NSArray *cusComponents = [line componentsSeparatedByString:@";"];

  // cusComponents now contains 3 entries - name, number, e-mail. Add this to your customer data array
  [self.cusNameDataArray addObject:cusComponents];
}

And now you have an array of customers. Each customer entry is an array of the 3 pieces of information. To get at it:

NSArray *customerData = [self.cusNameDataArray objectAtIndex:<customer number>];

NSString *customerName = [customerData objectAtIndex:0];
NSString *customerPhone = [customerData objectAtIndex:1];
NSString *customerEmail = [customerData objectAtIndex:2];

Is that the sort of thing you were after?


(One other thing to note: Having a variable declared in your class that is exactly the same as a local variable defined in a function is not ideal - it's easy to get confused as to which is being written to or read from, and silly bugs can easily crop up.)

thanx for quick response!

i used your code but nothing happens.

the cells of tableview are empty -> cell.textlabel.text and cell.detailtextlabel.text

did i make a silly mistake?

- (void)viewDidLoad
{
[super viewDidLoad];

self.title = NSLocalizedString(@"Customers", @"My Customers");

NSURL *url = [NSURL URLWithString:@"http://www.yourdomain.com/some.php?do=yes"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request startSynchronous];
NSError *error = [request error];
if (!error) {
NSString *response = [request responseString];
NSLog(@"%@", response);

NSArray *cusDataArray = nil;
cusDataArray = [[response componentsSeparatedByString:@"\n"]retain];

// Allocate my customer array
self.cusDataArray =[[NSMutableArray alloc] init];

for (int i=0; i<[cusTempArray count]; i++)
{
NSString *cusLine = [cusTempArray objectAtIndex:i];
NSArray *cusComponents = [cusLine componentsSeparatedByString:@";"];

// cusComponents now contains 3 entries - name, number, e-mail. Add this to your customer data array
[self.cusDataArray addObject:cusComponents];
}

}

[cusDataArray release];
}

-(UITableViewCell *)tableView:(UITableView *)cusTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *identifier = @"Cell";

UITableViewCell *cell = [self.cusTableView dequeueReusableCellWithIdentifier:identifier];
if(cell == nil)
//cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:identifier] autorelease];
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:identifier] autorelease];

// Iterate over ever line and break it up into its components
for (int i=0; i<[cusTempArray count]; i++)
{
NSString *cusLine = [cusTempArray objectAtIndex:i];
NSArray *cusComponents = [cusLine componentsSeparatedByString:@";"];

// cusComponents now contains 3 entries - name, number, e-mail. Add this to your customer data array
[self.cusDataArray addObject:cusComponents];
}

//Set up the cell...
cell.textLabel.font = [UIFont fontWithName:@"Verdana" size:12];
NSArray *customerData = [self.cusDataArray objectAtIndex:0];
NSString *customerName = [customerData objectAtIndex:0];
NSString *customerPhone = [customerData objectAtIndex:1];
cell.textLabel.text = customerName;
cell.detailTextLabel.font = [UIFont fontWithName:@"Verdana" size:10];
cell.detailTextLabel.text = [self.cusDataArray objectAtIndex:1];

return cell;
