这是我的第一个 iPhone 应用程序,它基于顶级 tableview。行的选择要么转到另一个 tableview 要么转到一个视图。该应用程序在模拟器上运行正常,但是当移植到我的 iPhone 时,它会因 EXC_BAD_ACCESS 错误而失败。在显示我的启动画面时会发生这种情况。NSLog 表示 appDelegate.m 中的程序处理:
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
但它只是失败了。代码似乎永远不会到达我的 RootViewController 中的 viewDidLoad。
我确定我已经把 RootViewController 和 appDelegates 搞混了,但无法弄清楚到底出了什么问题。我附上了我的 RootViewController appDelegate 的开始代码 - 任何帮助表示赞赏。
RootViewController.h 代码....
@interface RootViewController : UITableViewController {
TyresViewController *tyresController;
EngineSpecViewController *engineSpecController;
CarbonTaxBandViewController *carbonTaxBandController;
TyreSpecificationsViewController *tyreSpecificationsController;
FuelConsumptionandEmissionsViewController *fuelConsumptionandEmissionsController;
CompanyCarTaxBandViewController *companyCarTaxBandController;
CarbonCalculatorViewController *carbonCalculatorController;
ReminderViewController *reminderController;
//NSString *selectedSpecification;
NSArray *listOfItems;
}
RootViewController.m 代码......
#import "RootViewController.h"
@implementation RootViewController
@synthesize listOfItems;
//@synthesize selectedSpecification;
@synthesize carbonTaxBandController;
@synthesize engineSpecController;
@synthesize tyreSpecificationsController;
@synthesize tyresController;
@synthesize fuelConsumptionandEmissionsController;
@synthesize companyCarTaxBandController;
@synthesize carbonCalculatorController;
@synthesize reminderController;
appDelegate.h 代码.....
@interface MyCar3AppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
UINavigationController *navigationController;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
@结尾
appDelegate.m 代码.....
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Override point for customization after app launch
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
}
