TheOS iOS 以编程方式 UITableview 代码在滚动时崩溃

Question

我使用 TheOS 来开发我的越狱应用程序。这是我以编程方式编写的表格视图代码，我几乎做了最简单的方法来实现表格视图方法。表格视图将正确显示默认表格数据，但当我滚动表格视图时应用程序会崩溃。我的错误日志没有显示任何明显的日志。 请帮帮我，我真的不知道滚动视图时它会立即崩溃的原因。

#import "DeviceInfoTableViewController.h"

@interface DeviceInfoTableViewController ()

@end

@implementation DeviceInfoTableViewController
{
    NSArray *tableData;
}

- (void)loadView {
    [super loadView];
    self.title = @"Table View Controller";
}

- (void)viewDidLoad {
    [super viewDidLoad];

    // Initialize table data
    tableData = [NSArray arrayWithObjects:@"Egg Benedict", @"Mushroom Risotto", @"Full Breakfast", @"Hamburger", @"Ham and Egg Sandwich", @"Creme Brelee", @"White Chocolate Donut", @"Starbucks Coffee", @"Vegetable Curry", @"Instant Noodle with Egg", @"Noodle with BBQ Pork", @"Japanese Noodle with Pork", @"Green Tea", @"Thai Shrimp Cake", @"Angry Birds Cake", @"Ham and Cheese Panini", nil];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    NSLog(@"the tableData count: %ld", (unsigned long)tableData.count);
    return tableData.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (!cell) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    NSString *str = tableData[indexPath.row];
    cell.textLabel.text = str;
    return cell;
}

#pragma mark - Table view delegate

// In a xib-based application, navigation from a table can be handled in -tableView:didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    [tableView deselectRowAtIndexPath:indexPath animated:YES];

}

@end

我也去看了 ips 崩溃报告，但它没有显示任何有用的信息。

我通过这种方式从另一个 Root 视图控制器调用这个 tableView：

- (void)deviceInfoTap:(id)sender {
    DeviceInfoTableViewController *controller = [[DeviceInfoTableViewController alloc] init];
    [self.navigationController pushViewController:controller animated:YES];
}

Answer 1

这可能是由于对您的 tableData 的弱引用而发生的。为您的 tableData 分配强参考：

@interface DeviceInfoTableViewController ()

@property (nonatomic, strong) NSArray *tableData;

@end

然后在viewDidLoad中：

- (void)viewDidLoad {
    [super viewDidLoad];

    // Initialize table data
    _tableData = [NSArray arrayWithObjects:@"Egg Benedict", @"Mushroom Risotto", @"Full Breakfast", @"Hamburger", @"Ham and Egg Sandwich", @"Creme Brelee", @"White Chocolate Donut", @"Starbucks Coffee", @"Vegetable Curry", @"Instant Noodle with Egg", @"Noodle with BBQ Pork", @"Japanese Noodle with Pork", @"Green Tea", @"Thai Shrimp Cake", @"Angry Birds Cake", @"Ham and Cheese Panini", nil];
}
