今天Extension有一个标题，但没有iOS 8 [英] Today Extension has a title, but no body iOS 8

问题描述

我正在尝试新的 TodayExtensions 按照WWDC视频为iOS和OS X创建扩展，第1部分中所述创建今日扩展的步骤/ em>的。我在提供的故事板中为ViewController添加了一个彩色的UIView。我在今天通知中心获得了一个标题，但是我没有看到我的彩色视图。它看起来像这样（我做了两个）：

I am trying out the new TodayExtensions in iOS 8 and I followed the steps to create a Today Extension as described in the WWDC video Creating Extensions for iOS and OS X, Part 1. I added a colored UIView to the ViewController in the provided storyboard. I get a title in my "Today" Notification center, but I get no body with my colored view. It looks like this (I made two):

还有其他人得到这个吗？我在所有ViewControllers方法中设置了断点，没有任何东西被调用。我将Info.plist更改为直接转到我的VC类，而不是故事板，我什么都没得到。我可以在info.plist中更改今天扩展名的标题。

Is anyone else getting this? I set breakpoints in all of my ViewControllers methods and nothing gets called. I changed my Info.plist to just go directly to my VC class, instead of the storyboard and I get nothing still. I can change the title of the today extension in the info.plist.

推荐答案

首先，为了测试发生了什么，添加awakeFromNib到你的视图控制器并设置首选内容大小（Obj C中的所有代码）：

First, to test that anything is happening, add awakeFromNib to your view controller and set preferred content size (all code in Obj C):

- (void)awakeFromNib {
    [super awakeFromNib];
    [self setPreferredContentSize:CGSizeMake(self.view.bounds.size.width, 50)];
}

如上所述，请注释掉默认的init方法并创建一个空的initWithCoder ：绕过Beta 2中的一些错误：

As milesper said above, comment out the default init method and create an empty initWithCoder: to get around some bug in Beta 2:

-(id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
    if (self) {
        // init
    }
    return self;
}

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

现在清理然后再次运行。此时你应该看到它调整大小（确保添加带有文本的标签或要测试的东西）。

Now Clean and then run again. At this point you should see it resize (make sure you add a label with text or something to test).

确保使用普通的UIViewController类进行测试，而不是子类。一旦看到小部件大小响应，那么尝试一个子类。我今天花了一个小时才发现使用UICollectionViewController在Beta 2中不起作用（将提交RADAR）。

Make sure you test with a plain UIViewController class, not a subclass. Once you see your widget size respond, then try a subclass. I spent an hour today just to find out that using UICollectionViewController simply doesn't work in Beta 2 (will file a RADAR).
