2012-09-18 10:45:33.202 testStoryboard[5792:14203] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Requesting the window of a view (<UITableViewCell: 0x6b80190; frame = (0 0; 0 0); transform = [0, 0, 0, 0, 0, 0]; alpha = 0; opaque = NO; autoresize = W; layer = (null)>) with a nil layer. This view probably hasn't received initWithFrame: or initWithCoder:.'

terminate called throwing an exception(lldb)
Edit: here's my code:
// SecondTableViewController.m
#import "SecondTableViewController.h"
#interface SecondTableViewController ()
#end
#implementation SecondTableViewController
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
//Initialize the array.
myArray2 = [[NSMutableArray alloc] init];
//Add items
[myArray2 addObject:#"Iceland"];
[myArray2 addObject:#"Greenland"];
[myArray2 addObject:#"Switzerland"];
[myArray2 addObject:#"Norway"];
[myArray2 addObject:#"New Zealand"];
[myArray2 addObject:#"Greece"];
[myArray2 addObject:#"Rome"];
[myArray2 addObject:#"Ireland"];
//Set the title
self.navigationItem.title = #"Countries";
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [myArray2 count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [UITableViewCell alloc];
}
cell.textLabel.text = [myArray2 objectAtIndex:indexPath.row];
return cell;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Navigation logic may go here. Create and push another view controller.
/*
<#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:#"<#Nib name#>" bundle:nil];
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
*/
}
#end
I'm verry new to IOS, can someone set me in the right direction?

Answer 1

Your initiation of the cell is not complete, you have to init the cell, not just alloc it.
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
