Question

我在我的应用中使用了UINavigationController，由于某种原因，它不允许我将页面切换到名为CompanyView的third xib。它从第一个切换到第二个但不是第三个。我可能做错了但是如果有人能查看我的代码会很棒。我相信我按钮设置正确。以下是我不会更改视图的.h file xib：

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

@interface MenuView : UIViewController

-(IBAction)btnClicked:(id)sender;

@end

以下是.m file的代码：

#import "MenuView.h"

@implementation MenuView

-(IBAction)btnClicked:(id)sender {

    CompanyView * companyView = [[CompanyView alloc] init];

    companyView.title = @"Company";

    [self.navigationController pushViewController:companyView animated:YES];

    [companyView release];
}



- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (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.
}

#pragma mark - View lifecycle

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

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

- (BOOL)shouldAutorotateToInterfaceOrientation:    
(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

@end

Answer 1

尝试以这种方式初始化您的公司视图。

CompanyView *companyView = [[CompanyView alloc] initWithNibName:@"CompanyView" bundle:nil];

Answer 2

这就是我设置它的方式：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
        CategoryPresetViewController *controller = [[CategoryPresetViewController alloc] initWithPVCDelegate:avc];
        controller.title = [[factoryCategoryNameArray objectAtIndex:indexPath.row] retain];
        if (controller != nil){
            [self.navigationController pushViewController:controller animated:YES];

        [controller release];
}

也许它可以帮到你
