程序在 Ipad 程序中接收到信号 sigabrt

Question

我修复了所有警告，现在我的 AppDelegate 类中出现此类错误

.h 文件是

#import <UIKit/UIKit.h>

@interface UYLAppDelegate : UIResponder <UIApplicationDelegate>{

}

@property (retain, nonatomic) IBOutlet UIWindow *window;
@property (retain, nonatomic) IBOutlet UISplitViewController *splitViewController;

@end

.m 文件是

#import "UYLAppDelegate.h"
#import "UYLMasterViewController.h"
#import "UYLDetailViewController.h"
#import <QuartzCore/QuartzCore.h>

@implementation UYLAppDelegate

@synthesize window = _window;
@synthesize splitViewController = _splitViewController;

- (void)dealloc
{
    [_window release];
    [_splitViewController release];
    [super dealloc];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UIView *rootView = [[self.splitViewController.viewControllers objectAtIndex:0] view];
    rootView.layer.borderWidth = 1.0f;
    rootView.layer.cornerRadius =5.0f;
    rootView.layer.shadowOpacity = 0.8f;
    rootView.layer.shadowOffset = CGSizeMake(-5, 0);

    self.window.rootViewController = self.splitViewController; //error here
    [self.window makeKeyAndVisible];
    return YES;
}

@end

在这一行我犯了一个错误

self.window.rootViewController = self.splitViewController; //error here

SplitViewController 由 2 个控制器组成，.h 文件是：

#import <UIKit/UIKit.h>

@class UYLDetailViewController;

@interface UYLMasterViewController : UITableViewController

@property (retain, nonatomic) IBOutlet UYLDetailViewController *detailViewController;

@end

第二个

#import <UIKit/UIKit.h>
#import "UYLModalViewController.h"

@class UYLMasterViewController;

@interface UYLDetailViewController : UIViewController <UYLModalViewControllerDelegate>{
    UIBarButtonItem *_MessageButton;
    NSInteger modalViewShowType;
}

-(IBAction)buttonTapped:(id)sender;

@property (retain, nonatomic, getter=_MessageButton) IBOutlet UIBarButtonItem *someMessageButton;
@property (retain, nonatomic) NSNumber *detailItem;
@property (retain, nonatomic) IBOutlet UIToolbar *toolbar;
@property (retain, nonatomic) IBOutlet UILabel *detailTitle;
@property (retain, nonatomic) IBOutlet UILabel *detailDescriptionLabel;
@property (assign, nonatomic) BOOL masterIsVisible;

@end

编辑： 我在控制台中看到了所有内容

请帮我理解一下=(

我大部分时间都有一些SIGABRT 错误，这只是意味着它找不到您所指的那个实例。所以再看看那一行，想想哪些地方可能没有被宣布为正确的。

我认为如果您将其更改为。 self.window.rootViewController = splitViewController;
