我试图弄清楚如何让我的共享扩展程序访问网页并操纵其内容。我已经按照文档进行了操作，
但我一定遗漏了一些东西，因为我没有看到任何符合kUTTypePropertyList我认为应该的项目。
我的 plist 如下所示：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

</plist>
我的 ExtensionPreProcessing 看起来像这样：
ExtensionPreprocessingJS = {
run : function(arguments) {
arguments.completionFunction({"hello":"world"});
},
finalize : function(arguments) {
document.body.style.backgroundColor = 'red';
}
};
最后，我的 ShareViewController 看起来像这样：
class ShareViewController: UIViewController, NSExtensionRequestHandling {
override func viewDidLoad() {
let identifierType = NSString(format: kUTTypePropertyList, NSUTF8StringEncoding)
for (item: NSExtensionItem) in self.extensionContext?.inputItems as [NSExtensionItem] {
for (itemProvider: NSItemProvider) in item.attachments as [NSItemProvider] {
if itemProvider.hasItemConformingToTypeIdentifier(identifierType) {
println("why doesn't this happen?")
}
}
}
}
override func viewDidAppear(animated: Bool) {
}
override func beginRequestWithExtensionContext(context: NSExtensionContext) {
super.beginRequestWithExtensionContext(context)
let identifierType = NSString(format: kUTTypePropertyList, NSUTF8StringEncoding)
//println(self.extensionContext?.inputItems)
for (item: NSExtensionItem) in context.inputItems as [NSExtensionItem] {
for (itemProvider: NSItemProvider) in item.attachments as [NSItemProvider] {
if itemProvider.hasItemConformingToTypeIdentifier(identifierType) {
println("why doesn't this happen?")
}
}
}
}
}
注意我的 println 语句。他们从不执行。我基本上只是在寻找某种确认事情正在运行的确认。我的共享扩展显示在 Safari 中，但我认为我的自定义 javascript 没有运行。希望有人能发现我做错了什么。提前致谢
