ios推送到navigationController以黑屏结束

Question

我尝试通过其在线文档将 stripe 实现到 iOS 应用程序中。到目前为止一切都很好，现在将 paymentView 推到我的导航 Controller 堆栈上，我得到一个完全损坏的屏幕。认为这是条纹 View 的问题但是当我没有登录时(见下面的代码 - 没有给出识别 token )并且正在推送登录屏幕，它也完全是黑色的。这不会是该 View 的问题，因为如果我从另一个 View 推送登录 View 在此 View 之前，它加载得很好。

那么为什么通过下面的 buyButtonAction 推送 View 会给我黑屏/搞砸的屏幕？!我已经研究了几个小时了......似乎没有任何效果。

the important code part:

@interface PaymentViewController ()

@end

@implementation PaymentViewController

@synthesize stripeCard = _stripeCard;
@synthesize stripeView;
@synthesize passedProductId;

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

- (void)viewDidLoad
{


    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.stripeView = [[STPView alloc] initWithFrame:CGRectMake(15,20,290,55)
                                              andKey:@"pk_test_45mqixOu8N9S4lQ6cdn1OXBD"];
    self.stripeView.delegate = self;
    [self.view addSubview:self.stripeView];

}

还有电话:

-(void)buyButtonAction:(id)sender
{
    tokenClass *tokenObject = [tokenClass getInstance];
    NSLog(@"%@", tokenObject.token);
    if (tokenObject.token == nil) {
        LoginController *loginController = [[LoginController alloc] init];
        [self.navigationController pushViewController:loginController animated:YES];
    } else {
        NSLog(@"%@", tokenObject.token);
        CGPoint hitPoint = [sender convertPoint:CGPointZero toView:self.tableView];
        NSIndexPath *hitIndex = [self.tableView indexPathForRowAtPoint:hitPoint];
        PaymentViewController *payView = [[PaymentViewController alloc] init];
        payView.passedProductId = [[self.productData valueForKey:@"id"] objectAtIndex:hitIndex.row];
        NSLog(@"passing %@", payView.passedProductId);
        // push payment view
        payView.navigationItem.title = @"One-Click-Payment";
        [self.navigationController pushViewController:payView animated:YES];
    }
}

我们可以看到导航栏后面有一个 View 。这是一个与 iOS 7 相关的问题。将此行添加到您的 viewDidLoad:

 if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
    self.edgesForExtendedLayout = UIRectEdgeNone;

或者通过将 64 添加到 y 来更改您的 self.stripeView 框架:

CGRectMake(15,84,290,55)
