iphone - iAd——无法点击横幅

Question

我正在创建一个通用应用程序模板。

此模板需要支持可选的 iAd，以及所有方向(可选)。

我编写了一个解决方案，却发现了一个奇怪的错误。在某些情况下我无法点击横幅

然后，我重新编码了另一个版本，整理了所有内容，并删除了大部分代码以揭示最小的测试用例失败。

https://github.com/p-i-/iAdUniversalTemplate/commit/2c829d268a9452e1a054802e7ccb9cde5de17853

在这段新代码中，只有 3 个 View :窗口、uberview( View Controller 的 View )和广告横幅

因此，横幅在提供后会正确显示，自动旋转工作正常......我已经记录了每个的框架和边界，一切都如其应有。

但是它没有响应点击(好吧，点击因为我在模拟器中)

可能出了什么问题？我开始怀疑，在将 XIB 从项目中删除并从代码中实现窗口和 View Controller 时，我遗漏了某些内容或将某些内容从后到前连接起来。

有趣的代码块:

AppDelegate.m

- (BOOL) application: (UIApplication *) application 
didFinishLaunchingWithOptions: (NSDictionary *) launchOptions 
{
    NSLog(@"--> ___PROJECTNAME___AppDelegate:didFinishLaunchingWithOptions...");

    // FIXED: now entry in info.plist hides SB BEFORE launch
    [[UIApplication sharedApplication] setStatusBarHidden: (SHOW_SB ? NO : YES)];

    CGRect appFrame = [UIScreen mainScreen].applicationFrame;

    // windowRect must start at 0, 0
    // if (SHOW_SB == YES), appFrame will be '{{0, 20}, {320, 460}}'
    CGRect windowRect = CGRectMake(0, 0, appFrame.size.width, appFrame.size.height);

    self.window = [[[UIWindow alloc] initWithFrame: windowRect] autorelease];

    self.viewController = [ [ [ ___PROJECTNAME___ViewController alloc ] init ] autorelease ];

    [self.window setRootViewController: viewController];

    // triggers loadView
    [self.window makeKeyAndVisible];

    return YES;
}

Answer 1

这是一个令人讨厌的 bug

我最终不得不使用我的 2 个 ITS 帮助热线事件中的一个，并因此损失了一整周的工作时间。

将uberView的backgroundColor属性设置为ANYTHING非nil可以解决这个问题。

这是 XIB magic 完成的事情之一

有一个名为 nib2objc 的工具，可以将 XIB 转换为代码。如果我必须自己调试它，以实际查看 Apple 默认 XIB 中包含的内容，并查看我无法手动实现的内容，那么这将是下一步。

但这是 UIKit 中的一个 BUG。 Apple 的 ITS 代表告诉我要这样做，我已经这样做了。
