iAd——无法点击横幅
我正在创建一个通用应用程序模板。
该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,我无法单击横幅,
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/pi-/iAdUniversalTemplate/commit/2c829d268a9452e1a054802e7ccb9cde5de1 7853
在此新代码,只有 3 个视图:窗口、uberview(视图控制器的视图)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,一切都应该是这样的。
但它没有响应点击(好吧,点击因为我在模拟器中)
可能是什么问题?我开始怀疑,在将 XIB 从项目中删除并从代码中实现窗口和视图控制器时,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:

I am creating a universal-app template.
This template will need to support optional iAds, and optionally all orientations.
I coded up a solution only to find a bizarre bug. in certain situations I was unable to click on the banner
I then recoded another revision, tidied everything, and gutted out most of the code to reveal a minimal test case failure.
https://github.com/p-i-/iAdUniversalTemplate/commit/2c829d268a9452e1a054802e7ccb9cde5de17853
In this new code, only 3 views: window, uberview (the view controller's view), and the ad-banner
So, the banner displays properly once it has been served, autorotation works fine...
I have logged the frame and bounds for each, and everything is as it should be.
But it is not responding to tap (well, click because I am in the simulator)
What could possibly be wrong? I'm starting to suspect that in cutting the XIB out of the project and implementing the window and view controller from code, I have missed something out or wired something up back to front.
Juicy code chunks:
AppDelegate.m
- (BOOL) application: (UIApplication *) application
didFinishLaunchingWithOptions: (NSDictionary *) launchOptions
{
NSLog(@"--> ___PROJECTNAME___AppDelegate:didFinishLaunchingWithOptions...");

[[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];

[self.window makeKeyAndVisible];
return YES;

这是一个非常糟糕的错误,
我最终不得不使用我的 2 个 ITS 帮助热线事件中的一个,并为此损失了整整一周的工作时间。
将 uberView 的 backgroundColor 属性设置为 ANYTHING 非零可以解决该问题。
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。苹果公司的 ITS 代表告诉我要这样做,我已经这样做了。
This was a bitch of a bug to blat
I ended up having to use one of my 2 ITS helpline incidents, and lost a full working week on it.
Setting the uberView's backgroundColor property to ANYTHING non-nil fixes the problem.
This is one of the things that gets done by XIB magic
There is a tool called nib2objc that converts XIB into code. this would have been the next step if I had to debug it myself, to actually see what is contained in Apple's default XIB, and see what I'm failing to implement manually.
But this is a BUG in UIKit. Apple's ITS rep told me to file it does such, which I have done.
我遇到了同样的问题,但是使用 [UIColor clearColor] 作为超级视图的背景没有帮助。 (这是在 iOS 4.3.3 上)
所有超级视图都需要有一个不透明颜色集。
I had the same problem, but using [UIColor clearColor] for the superview's background did not help. (This is on iOS 4.3.3)
All the superviews need to have an opaque color set.
我确实确认添加
didFinishLaunchingWithOptions 函数效果很好。
I do confirm that adding
in didFinishLaunchingWithOptions function works perfectly.
