EXC_BAD_ACCESS自定義類的初始化

Question

我寫了下面的類：

.h：

#import <Foundation/Foundation.h> 
@class TDLPaneViewController; 

@interface TDLSubViewController : NSObject 

@property (nonatomic, strong) IBOutlet UIView* view; 
@property (nonatomic, strong) TDLPaneViewController* paneViewController; 

- (id) initWithNibName:(NSString*)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil; 

- (void)viewWillAppear:(BOOL)animated; 
- (void)viewDidAppear:(BOOL)animated; 
- (void)viewWillDisppear:(BOOL)animated; 
- (void)viewDidDisppear:(BOOL)animated; 

@end 

.m：

#import "TDLSubViewController.h" 

@interface TDLSubViewController() 
{ 
    UIView *view; 
} 

@property (nonatomic, strong) NSString* nibName; 
@property (nonatomic, strong) NSBundle* nibBundle; 

@end 

@implementation TDLSubViewController 

@synthesize paneViewController, view; 
@synthesize nibName, nibBundle; 

- (id)initWithNibName:(NSString*)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil 
{ 
    self = [super init]; 

    if (self) 
    { 
      self.nibName = nibNameOrNil; 
      self.nibBundle = nibBundleOrNil; 
    } 
} 

- (void)viewWillAppear:(BOOL)animated 
{ 
    NSLog(@"viewWillAppear:%i", animated); 
} 
- (void)viewDidAppear:(BOOL)animated 
{ 
    NSLog(@"viewDidAppear:%i", animated); 
} 
- (void)viewWillDisppear:(BOOL)animated 
{ 
    NSLog(@"viewWillDisppear:%i", animated); 
} 
- (void)viewDidDisppear:(BOOL)animated 
{ 
    NSLog(@"viewDidDisppear:%i", animated); 
} 

@end 

出另一種觀點認爲，當我得到錯誤： - （空） viewDidAppear：（BOOL）animated { [super viewDidAppear：animated];

 TDLTestSubViewController* subView = [[TDLTestSubViewController alloc] initWithNibName:@"TDLTestSubViewController" bundle:nil] ; 

    [self pushSubViewController:nil animated:YES leftSide:YES]; 

} 

TDLTestSubViewController是TDLSubViewController的子類。

如果我使用UIViewController而不是TDLTestSubViewController，那麼一切正常，如果我關閉它也可以。所以我認爲問題出在TDLSubViewController類中。請提出什麼可能是錯誤的？

您的initWithNibName:bundle:方法在必須時不返回self。
