的iOS - UITableViewCell的初始化失敗，EXC_BAD_ACCESS

Question

我簡單的認爲是一個UINavigationController的第三級，這表明從筆尖一個空表，這裏是.m文件的代碼：

#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 

當我運行它，設備死機和調試器說是有這條線一EXC_BAD_ACCESS：

 cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 

我相同的代碼在UINavigationController的第二個層次，它做工精細，真的不要」不明白什麼是錯的。

感謝所有幫助:)

Answer 1

static NSString *CellIdentifier =@"Cell"; 

不

static NSString *CellIdentifier = "Cell"; 

更超過

return cell;//not found on ur code 

Answer 2

可能是你應該return cell在這個方法：

- (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; 
} 

更新時間：

而且如前所述@AppleVijay初始化CellIdentifier
