以下是我在调试区域收到的错误消息.它运行正常,没有任何错误,除了我收到此错误.这会阻止苹果接受应用吗？我如何解决它？

2012-07-26 01:58:18.621 Rolo[33597:11303] Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
    "<NSAutoresizingMaskLayoutConstraint:0x887d630 h=--& v=--& V:[UIButtonLabel:0x886ed80(19)]>",
    "<NSAutoresizingMaskLayoutConstraint:0x887d5f0 h=--& …

这是在我的.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self.scrollView addSubview:self.contentView];
    self.scrollView.contentSize = self.contentView.bounds.size;
    NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];

    NSMutableArray *arr = [[NSMutableArray alloc]init];
    arr = [Singleton getArray];

    NSString *str = [arr componentsJoinedByString:@"\n"];
    summaryLabel.text = str;
}

这是我的.h

@interface TotalViewController : UIViewController
{
    UIScrollView *scrollView;
    UIView *contentView;

}
@property (nonatomic, retain) IBOutlet UIScrollView * scrollView;
@property (nonatomic, retain) IBOutlet UIView       * contentView;
@property (nonatomic,strong) IBOutlet UILabel       * summaryLabel;

我的标签连接到视图控制器,我的contentView连接到视图控制器,我的summaryLabel连接到视图控制器.我需要标签滚动而不是.

thread 1: EXC_BAD_ACCESS (code=1, address = 0x70 当我在我的时候,我得到以下错误消息addCustomerViewController,或者单击保存,在代码运行结束时self.navigationController!.popViewControllerAnimated(true),或者当我单击相同时addCustomerViewController.用错误突出显示的代码行在我的AppDelegate类中,它的第一行如下所示

class AppDelegate: UIResponder, UIApplicationDelegate{

这是我在调试区域中获得的最后一条消息.不确定它是否相关.

2015-06-17 23:03:03.744 SalesCRM[4930:1409291] CoreData: error: Failed to call designated initializer on NSManagedObject class 'Customer' 

这是保存功能.让我知道您可能需要查看的其他代码.我迷失了如何解决这个问题.

@IBAction func save(sender: AnyObject) {

    let appDel:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate

    let context:NSManagedObjectContext = appDel.managedObjectContext


    if firstName.text != "" && lastName.text != "" && phoneNumber.text != ""
    {
        let newUser = NSEntityDescription.insertNewObjectForEntityForName("Customer", inManagedObjectContext: context) as NSManagedObject
        newUser.setValue(firstName.text?.lowercaseString, forKey: "firstName")
        newUser.setValue(lastName.text?.lowercaseString, forKey: "lastName")
        newUser.setValue(phoneNumber.text, forKey: "phoneNumber")
        newUser.setValue(email.text, …

我在创建程序时使用的是Xcode 4.5 Beta 3.当我尝试切换到Xcode 4.4时,它给出了以下错误.如何在此版本的xcode中使用它.

The document "MainStoryboard.storyboard" could not be opened. This version of Xcode does not

这行代码在我的电子邮件文本字段编辑DidEnd 时运行。NSLog 运行，所以我知道该函数已运行，但键盘仍然没有消失。我已将文本框连接为委托。我已经确保故事板中的连接存在。依然不会改变。帮助。谢谢。

- (IBAction)emailDone2:(id)sender
{
    [_email resignFirstResponder];
    NSLog(@"emailDone2");
}

编辑* *我按照指示更改了代码，但这仍然没有任何作用。什么也没有变。

- (IBAction)emailDone2:(id)sender
{
    [self.view endEditing:TRUE];
}

我正在尝试从表格视图切换到详细视图.当我点击单元格时它会崩溃.我已经使用了休息来尝试找到它崩溃的代码,但我找不到特定的行.当从表视图到详细视图执行segue时,它会崩溃.我想将一些变量传递给详细视图但我首先需要让它切换到详细视图.我正在使用故事板fyi.任何帮助,将不胜感激.

更新:崩溃日志如下

arg c = (int) 1
arg v = (char **) 0x2fd63cdc

这就是崩溃的路线

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

更新2

当我逐步完成代码时崩溃之前的最后一段代码就是为segue函数做准备.在那里的最后一行代码之后它崩溃并转到上面的一行.

更新3

我意识到控制台已被隐藏,因此这是控制台中显示的错误.我的两个准备segue的nslog都被调用了.
