iOS - UITableViewCell initialization fail, EXC_BAD_ACCESS - ios

Question

i've a simple View that is the third level of a UINavigationController, it show an empty table from a nib, here is the code of the .m file:
#import "ThirdLevel.h"
#implementation ThirdLevel
#synthesize lista, categoria;
- (void)viewDidLoad {
[super viewDidLoad];
NSLog(#"Categoria: %#", categoria);
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Overriden to allow any orientation.
return NO;
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc. that aren't in use.
}
- (void)viewDidUnload {
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 20;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 100;
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//newtableView.separatorColor = [UIColor clearColor];
static NSString *CellIdentifier = "Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
}
- (void)buttonPressed:(id)sender {
NSLog(#"premuto");
}
- (void)dealloc {
[super dealloc];
}
#end
When i run it, the device crash and the debugger say that there is a EXC_BAD_ACCESS at this line:
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
i've the same code in the second level of the UINavigationController and it work fine, realy don't understand what's wrong.
Thanks for any help :)

Answer 1

static NSString *CellIdentifier =#"Cell";
not
static NSString *CellIdentifier = "Cell";
more over
return cell;//not found on ur code

Answer 2

May be you should return cell in this method:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//newtableView.separatorColor = [UIColor clearColor];
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
return cell;
}
Updated:
And as mentioned #AppleVijay add # when initializing CellIdentifier
