iOS - UITableViewCell 初始化失败，EXC_BAD_ACCESS

Question

我有一个简单的 View ，它是 UINavigationController 的第三级，它显示了一个 nib 的空表，这是 .m 文件的代码:

#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

当我运行它时，设备崩溃并且调试器说这一行有一个 EXC_BAD_ACCESS:

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

我在 UINavigationController 的第二级有相同的代码，它工作正常，真的不明白出了什么问题。

谢谢你的帮助 :)

Answer 1

  static NSString *CellIdentifier =@"Cell";

不是

  static NSString *CellIdentifier = "Cell";

而且

 return cell;//not found on ur code
