我有一个UITableView分隔符设置为单行.

在iPhone <= 5s上,一切看起来都很好,但在6和6 Plus(设备以及模拟器)上,分隔符的厚度不同.它更糟糕,因为它们在滚动时闪烁,看起来非常糟糕.我没有手动设置高度,所以我不知道是什么造成了这个.

如您所见,前两行比后两行稍厚.现在,如果我滚动,它们会从厚到薄变回,所以它看起来像闪烁......

滚动浏览UICollectionView时我的应用程序崩溃,但仅在iOS 10下:

Uncaught exception: layout attributes for supplementary item at index path
(<NSIndexPath: 0xc000000000000116> {length = 2, path = 1 - 0})
changed from <UICollectionViewLayoutAttributes: 0x6080001ec400>
index path: (<NSIndexPath: 0xc000000000000116> {length = 2, path = 1 - 0});
element kind: (UICollectionElementKindSectionHeader); frame = (0 8995; 414 180);
zIndex = 1024;  to <UICollectionViewLayoutAttributes: 0x6080001e8200>
index path: (<NSIndexPath: 0xc000000000000116> {length = 2, path = 1 - 0});
element kind: (UICollectionElementKindSectionHeader);
frame = (0 8994; 414 180); zIndex = 1024;  without invalidating the …

鉴于以下代码：

    enum MyError: Error {
        case someError
    }

    myButton.publisher(for: .touchUpInside).tryMap({ _ in
        if Bool.random() {
            throw MyError.someError
        } else {
            return "we're in the else case"
        }
    })
        .replaceError(with: "replaced Error")
        .sink(receiveCompletion: { (completed) in
            print(completed)
        }, receiveValue: { (sadf) in
            print(sadf)
        }).store(in: &cancellables)

每当我点击按钮时，我都会得到we're in the else case直到Bool.random()为真 - 现在抛出一个错误。我尝试了不同的方法，但我无法捕获/替换/忽略错误并在点击按钮后继续。

在代码示例中，我希望有以下输出

we're in the else case
we're in the else case
replaced Error
we're in the else case
...

相反，我得到finished了replaced error并且没有发出任何事件。 …

我在UITextField的子类中使用AutoLayout,但有时我收到以下错误/ stacktrace:

我有一个带有可可触摸框架的iOS项目,我想使用CocoaPods.据我所知,一切都运行正常,但是我收到了包含所有pod的以下警告(这里以示例为例)MagicalRecord.

objc[56961]: Class MagicalRecord is implemented in both /Users/stefan/Library/Developer/Xcode/DerivedData/FrameworkPlayground-ecdubsjzkmacfihjxoxvlznqvgmg/Build/Products/Debug-iphonesimulator/SharedDataSource.framework/SharedDataSource and /Users/stefan/Library/Developer/CoreSimulator/Devices/41B1BE94-1242-4538-8D60-23BAC3337308/data/Containers/Bundle/Application/B8ADA4E6-02BC-4095-8A14-D254C13D0928/FrameworkPlayground.app/FrameworkPlayground. One of the two will be used. Which one is undefined.

我将Xcode项目上传到github,可以在这里找到:https://github.com/haemi/FrameworkWithCocoaPods

这里有两张来自当前设置的图片:

我们的用户不时收到电子邮件,例如更改密码.当他们点击链接时,我希望将它们发送到我们的网站,但我们的Android应用程序会被打开.

链接例如是https://www.ourdomain.com/change-password/{random-string}.

我们在应用中启用了深层链接,但它们的配置方式如下:

            <intent-filter android:label="...">
            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                android:host="customhost"
                android:pathPrefix="/"
                android:scheme="https" />

            <data
                android:host="www.ourdomain.com"
                android:pathPrefix="/somethingelse"
                android:scheme="https" />

            <data
                android:host="www.ourdomain.com"
                android:pathPrefix="/againsomethingelse"
                android:scheme="https" />

            <data
                android:host="someothercustomhost"
                android:scheme="https" />

            <data
                android:host="andagainacustomhost"
                android:scheme="https" />
        </intent-filter>

因此该change-password部分不适合任何配置,但是我们的应用程序可能会被打开的原因是什么？

编辑

似乎问题是第一个data标签; 如果我评论出来,它的行为与预期一致(即https://www.ourdomain.com/change-password/1234不由应用程序处理).我不知道为什么这customhost是一个完全不同的词www.ourdomain.com...

我想发布一个可可触摸框架,其中包含一些json文件,其中包含我不希望framwork的用户看到的逻辑; 不幸的是,在.framework文件中仍然可以看到json.

我想把它包含在一个快速文件中:

struct JsonProvider {
    static let json = "..."
}

但是我的json很大,文件不再可用了.我找不到命令行编译的解决方案然后包含它.

是否有解决这两个问题之一,即

• 隐藏框架内的json或
• 预编译一个swift文件,然后将其添加到框架中？

We try to detect lane lines on a running track (and with this information the upcoming direction).

We currently use the following (simplified) steps:

1. Binary: transform the input with a binary threshold

2. Cropped: crop the region of interest (currently just the lower half of the image)

3. Canny: detect edges and group them with HoughLinesP

4. Upward Lines & Closing: only keep lines with an extreme slope - ignore horizontal lines

5. Result: find connected components and fit quadratic function through each line …

当我点击屏幕底部的文本字段时,会出现键盘并隐藏活动元素.在iOS上,它完美无缺.

我能够滚动表单,因此文本字段位于可见区域,但这并不好看.我做错了什么或这是一个已知的错误,因为我在Sencha Touch本身的示例中有相同的行为:docs.sencha.com/touch/2-1/touch-build/examples/forms/

如果在这个表格上:

我点击"Bio"的文本字段,键盘隐藏了文本字段,而不是滚动文本字段以使其在输入时可见:

我正在使用Core Data MagicalRecord,我的模型有两种配置:

PrefilledConfiguration有四个实体,UserDataConfigurations有六个.现在我想将它们全部合并到默认配置中 - 实现这一目标的最佳方法是什么？

是否需要迁移？如何将所有现有数据传输到新的合并(默认？)配置？
