I am designing a simple navigation based application for EmployeeContactDirectory. I am displaying the list of Employee. For showing the list of employee, I am using the restfull webservice. I am getting proper response as I want. I have a utility class for Employee Data, class is EmployeeData.h and Employee.m (contains employeeId , employeeFirstName, employeeLastName). My code for parsing
// Code for parsing the response and getting desired field into the dictionary object and add the dictionaries into the array.
-(void)finishedReceivingData:(NSData *)data {
NSData *dataRes = [[restConnection stringData] dataUsingEncoding:NSUTF8StringEncoding];
////////////////Parsing with XPathQuery Start//////////////////////
if (dataRes != NULL) {
employeeData = [[EmployeeData alloc] init];
NSString *xPathQuery = [NSString stringWithFormat:@"/*",employeeData.employeeID];
NSArray *arrayWithObjectList = PerformXMLXPathQuery(dataRes, xPathQuery);
for(NSDictionary *childOfObjectList in arrayWithObjectList){
NSArray *arrayOfDataValueObj = (NSArray *)[childOfObjectList objectForKey:@"nodeChildArray"];
for(NSDictionary *childObjListDict in arrayOfDataValueObj){
NSArray *childObjListDataValue = (NSArray *)[childObjListDict objectForKey:@"nodeChildArray"];
for(NSDictionary *childDict in childObjListDataValue){
if([[childDict objectForKey:@"nodeName"] isEqualToString:@"FName" ])
{
employeeData.employeeFirstName = [childDict objectForKey:@"nodeContent"];
}
if([[childDict objectForKey:@"nodeName"] isEqualToString:@"EmpID"])
{
employeeData.employeeID = [childDict objectForKey:@"nodeContent"];
}
}
//employeeFirstNameArray = [NSArray arrayWithObjects:employeeData, nil];
employeeIDArray = [NSArray arrayWithObjects:employeeData, nil];
dictionaryEmployeeFirstName = [NSDictionary dictionaryWithObject:employeeData.employeeFirstName forKey:@"employeeData"];
dictionaryEmployeeID = [NSDictionary dictionaryWithObject:employeeData.employeeID forKey:@"employeeData"];
tempArray = [NSArray arrayWithObjects:dictionaryEmployeeFirstName, dictionaryEmployeeID, nil];
NSLog(@"size of temp %d",[tempArray count]);
}
}
//[employeeData release];
//employeeData = nil;
}
[self.tableviewEmloyeeList reloadData];
//////////////////////////////Parsing with XPathQuery end//////////
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell..
NSDictionary *dictionaryEmployee = [tempArray objectAtIndex:indexPath.row];
NSArray *firstNameArray = [dictionaryEmployee objectForKey:@"employeeData"];
NSString *cellValue = [firstNameArray objectAtIndex:indexPath.row];
NSLog(@"cellValue %@",cellValue);
cell.textLabel.text = cellValue;
return cell;
}
I am getting the message (Exc_bad_Access) when this line of code comes into the execution flow:
NSDictionary *dictionaryEmployee = [tempArray objectAtIndex:indexPath.row]
The EXC_Bad_Access is at the mail.m file at line nt retVal = UIApplicationMain(argc, argv, nil, nil);
So, Please tell me how can I set the data into the tableview when I am using NSDictionary. When, user clicks on the row of the tableview it will return the id of the selected employee.
Instead of the line
tempArray = [NSArray arrayWithObjects:dictionaryEmployeeFirstName, dictionaryEmployeeID, nil];
try the following,
if( tempArray )
{
[tempArray release];
tempArray = nil;
}
tempArray = [[NSArray arrayWithObjects:dictionaryEmployeeFirstName, dictionaryEmployeeID, nil] retain];
Since it is autoreleased, it might have been out of memory.
you need to implement a tableView delegate method called
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
here you will get the section & row clicked in the table
