Question

我正在创建一个通用应用模板。

此模板需要支持可选的iAd，以及可选的所有方向。

我编写了一个解决方案，但却发现了一个奇怪的错误。在某些情况下，我无法点击横幅

然后我重新编写了另一个修订版，整理了所有内容，并将大部分代码排除在外，以显示最小的测试用例失败。

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

在这个新代码中，只有3个视图：window，uberview（视图控制器的视图）和广告横幅

所以，横幅一旦送达就会正常显示，自动旋转工作正常...... 我已经记录了每个框架和边界，一切都是应该的。

但它没有响应tap（好吧，点击因为我在模拟器中）

可能出现什么问题？我开始怀疑在将XIB从项目中删除并实现窗口并从代码中查看控制器时，我已经错过了一些东西或者将某些内容连接到了前面。

多汁代码块：

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

这是一个惹人厌恶的错误

我最终不得不使用我的2个ITS帮助热线事件中的一个，并且在整个工作周内丢失了。

将uberView的backgroundColor属性设置为ANYTHING non-nil可以解决问题。

这是XIB魔术所做的事情之一

有一个名为nib2objc的工具可将XIB转换为代码。如果我必须自己调试它，实际看到Apple的默认XIB中包含的内容，看看我未能手动实现的内容，这将是下一步。

但这是UIKit的BUG。 Apple的ITS代表告诉我提交它的确是这样的，我已经做过了。

Answer 2

我有同样的问题，但使用[UIColor clearColor]作为superview的背景并没有帮助。（这是在iOS 4.3.3上）

所有超级视图都需要有不透明的颜色集。

Answer 3

我确认添加

self.window.backgroundColor = [UIColor whiteColor];

didFinishLaunchingWithOptions 中的

功能完美无缺。

iAd - 无法点击横幅
