Ios UIView与UITableView滚动崩溃应用程序

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IBOutlet
• 在类标题中调用UITableViewDelegate和DataSource

然后我试着像这样在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];

}

我还确保在这个类中设置了DataSource和tableView委托

- (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

当我试图滚动UITableView时，它崩溃了，这就是它所说的

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

没有任何内容输出到控制台，因此很难理解此错误的含义

更新1:cellForRowAtIndexPath方法 更新2：堆栈跟踪 它显示与工具栏或视图中的任何UIButton的任何交互都会导致错误。下面是堆栈跟踪

请发布崩溃消息。我已更新了错误代码。。很抱歉，这里没有足够的信息进行诊断。请发布完整的堆栈跟踪。转到Xcode中的断点导航器并单击左下角的加号（+）。选择“添加异常断点”。然后试着运行你的应用程序，你可能会看到它崩溃的代码行。这意味着你的ViewController已经被解除分配，这很奇怪。可能会在创建viewController的位置发布代码（来自appDelegate？）。另外，发布stacktrace（从中获得EXC_断点）。
