iphone ios官网 - 我可以通过UIAppearance代理设置哪些属性?




developer guide (2)

可以通过UIAppearance设置的属性在相应的头文件中用UI_APPEARANCE_SELECTOR标记。

要生成使用UI_APPEARANCE_SELECTOR标记的属性列表,可以在终端中使用以下unix命令:

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer‌​/SDKs/iPhoneOS5.1.sdk/System/Library/Frameworks/UIKit.framework/Headers
grep -H UI_APPEARANCE_SELECTOR ./* | sed 's/ __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_5_0) UI_APPEARANCE_SELECTOR;//'

这是我使用上述命令编译的一个列表。 这是针对5.0 SDK的。 为简洁起见,相应的getter方法已被省略。

(2012年7月3日) :此列表直到最新版本的XCode(4.3.3)都没有改变。

(2013年3月12日) :更新了SDK 6.1的列表。 适用于iOS 6.0(或更高版本)的属性列在[iOS 6.0]标签下。

(2013年10月24日) :更新SDK 7.0的列表。 适用于iOS 7.0(或更高版本)的属性列在[iOS 7.0]标签下。

我可以通过UIAppearance代理设置哪些属性? Apple的UIKit文档没有列出它们。 是否有这些属性的列表?


There are many answers to this questions offering many different ways to perform view controller communication that would indeed work, but I don't see anywhere mentioned which one are actually best to use and which ones to avoid.

In practice, in my opinion only a few solutions are recommended:

  • To pass data forward:
    • override the prepare(for:sender:) method of UIViewController when using a storyboard and segues
    • pass data through an initializer or through properties when performing view controller transitions thtough code
  • To pass data backwards
    • update the app shared state (which you can pass forward between view controllers with either one of the methods above)
    • use delegation
    • use an unwind segue

Solutions I recommend NOT to use:

  • Referencing the previous controller directly instead of using delegation
  • Sharing data through a singleton
  • Passing data through the app delegate
  • Sharing data through the user defaults
  • Passing data through notifications

These solutions, although working in the short term, introduce too many dependencies that will garble the architecture of the app and create more problems later.

For those interested, I wrote some articles that address these points more in depth and highlight the various drawbacks:
