更新1：cellForRowAtIndexPath方法

Question

我创建了一个包含UIView，UIToolbar和UITableView的UIViewController。这就是我创建视图所做的。

将元素连接到Interfacebuilder中的IBOutlets
在类标题

然后我试图像这样在ViewDidLoad中设置视图。

- (void)viewDidLoad
{
    [super viewDidLoad];
    colorController = [[ColorController alloc] init];
    [colorController readColorPlist];

    //create toolbar
    myToolBar = [[UIToolbar alloc] init];
    [myToolBar setTranslucent:NO];
    myToolBar.frame = CGRectMake(0.0, 0.0, 320.0, 45.0);
    [[UIToolbar appearance] setBarTintColor:[UIColor colorWithRed:colorController.oRed/255.0 green:colorController.oGreen/255.0 blue:colorController.oBlue/255.0 alpha:1.0]];

    // add title to toolBar
    UILabel *toolBarLabel = [[UILabel alloc] initWithFrame:CGRectMake((self.view.frame.size.width - 110.0) / 2, 3.0, 110.0, 40.0)];
    toolBarLabel.font = [UIFont boldSystemFontOfSize:16];
    toolBarLabel.textAlignment = NSTextAlignmentCenter;
    toolBarLabel.textColor = [UIColor whiteColor];
    toolBarLabel.backgroundColor = [UIColor clearColor];
    toolBarLabel.text = @"My View";

    // create TableView
    myTableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 45.0, self.view.frame.size.width, self.view.frame.size.width - 65)];
    [myTableView setDelegate:self];
    [myTableView setDataSource:self];

    // createButtons
    // create an array for the buttons
    NSMutableArray* barButtonsArray = [[NSMutableArray alloc] initWithCapacity:5];

    // create a Cancel button
    UIBarButtonItem * cancelButton = [[UIBarButtonItem alloc] initWithTitle:@"Cancel"
                                                                      style:UIBarButtonItemStylePlain
                                                                     target:self
                                                                     action:@selector(cancelUIButton)];

    cancelButton.style = UIBarButtonItemStyleBordered;
    cancelButton.tintColor = [UIColor whiteColor];
    [barButtonsArray  addObject:cancelButton];

    UIBarButtonItem *flexible = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    [barButtonsArray addObject:flexible];

    // create a submitButton
    UIBarButtonItem *submitButton = [[UIBarButtonItem alloc]initWithTitle:@"Submit"
                                                                    style:UIBarButtonItemStylePlain
                                                                   target:self
                                                                   action:@selector(submitButton)];
    submitButton.style = UIBarButtonItemStyleBordered;
    submitButton.tintColor = [UIColor whiteColor];
    [barButtonsArray  addObject:submitButton];

    // put the BarbuttonsArray in the toolbar and release them
    [myToolBar setItems:barButtonsArray  animated:NO];



    // add the views
    [self.view addSubview:myTableView];

    [self.view addSubview:myToolBar];
    [myToolBar addSubview:toolBarLabel];

}

我还确保在此类中设置了DataSource和tableView Delegate

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

这就是我试图滚动UITableView

时崩溃的原因

Thread 1:EXC_BAD_ACCESS(code=1, address=0x415dc466)'

没有任何内容输出到控制台，所以很难弄清楚这个错误意味着什么。

更新1：cellForRowAtIndexPath方法

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    // Configure the cell...

    return cell;
}

更新2：堆栈跟踪

似乎与工具栏中的任何UIButton或视图的任何交互都会导致错误。下面是堆栈跟踪。
