Tableview not down down

Question

好的，下面是加载Schedule nib的AppDelegate中的代码。

Schedule *newestVideoController = [[Schedule alloc] initWithNibName:@"Schedule" bundle:nil]; 
    newestVideoController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"Schedule" image:[UIImage imageNamed:@"app-icon_2_newest.png"] tag:2]; 
    NSArray *controllers = [NSArray arrayWithObjects:navController, newestVideoController, nil]; 
    mainController.viewControllers = controllers; 

现在这里是我的时间表头文件。

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


@interface Schedule : UITableViewController 
<UITableViewDelegate, UITableViewDataSource> { 
    NSArray *mySchedule; 

} 

@property (nonatomic,retain) NSArray *mySchedule; 

@end 

最后这里再次是我的“Schedule”实施文件。

#import "Schedule.h" 
#import "AnotherViewController.h" 


@implementation Schedule 

@synthesize mySchedule; 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ 

    return mySchedule.count; 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView 
     cellForRowAtIndexPath:(NSIndexPath *)indexPath{ 
    //create a cell 
    UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault 
                reuseIdentifier:@"cell"]; 
    //fill it with contents 
    cell.textLabel.text = [mySchedule objectAtIndex:indexPath.row]; 
    //return it 
    return cell; 
} 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 
    AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherViewController" bundle:nil]; 
    [self.navigationController pushViewController:anotherViewController animated:YES]; 
    [anotherViewController release]; 



} 

/* 
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. 
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { 
     // Custom initialization 
    } 
    return self; 
} 
*/ 


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib. 
- (void)viewDidLoad { 
    NSString *myFile = [[NSBundle mainBundle] pathForResource:@"exercise" ofType:@"plist"]; 
    mySchedule = [[NSArray alloc] initWithContentsOfFile:myFile]; 

    [super viewDidLoad]; 
} 


/* 
// Override to allow orientations other than the default portrait orientation. 
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    // Return YES for supported orientations 
    return (interfaceOrientation == UIInterfaceOrientationPortrait); 
} 
*/ 

- (void)didReceiveMemoryWarning { 
    // Releases the view if it doesn't have a superview. 
    [super didReceiveMemoryWarning]; 

    // Release any cached data, images, etc that aren't in use. 
} 

- (void)viewDidUnload { 
    // Release any retained subviews of the main view. 
    // e.g. self.myOutlet = nil; 
} 


- (void)dealloc { 
    [super dealloc]; 
} 


@end 

Answer 1

需要更多的代码/信息。它看起来像你实现了tableView：didSelectRowAtIndexPath：并将另一个View Controller正确地推入堆栈，所以很难说。但这里有一个命中列表：

• 你确定tableView：didSelectRowAtIndexPath：被调用吗？你有没有设置一个断点？如果没有，您可能忘记将您的Schedule类设置为代理程序，或者以编程方式或在Interface Builder中。

• 日程安排的导航控制器是否已设定？也就是说，它被推到导航控制器堆栈上吗？

• 你确定AnotherViewController的nib文件存在吗？
