我刚刚开始在NSLinguisticTagger我的博客上使用我的代码:NSLinguisticTagger @ NSHipster.com

NSLinguisticTaggerOptions options = NSLinguisticTaggerOmitWhitespace | NSLinguisticTaggerOmitPunctuation | NSLinguisticTaggerJoinNames;
NSLinguisticTagger *tagger = [[NSLinguisticTagger alloc] initWithTagSchemes: [NSLinguisticTagger availableTagSchemesForLanguage:@"en"] options:options];
tagger.string = question;
[tagger enumerateTagsInRange:NSMakeRange(0, [question length]) scheme:NSLinguisticTagSchemeNameTypeOrLexicalClass options:options usingBlock:^(NSString *tag, NSRange tokenRange, NSRange sentenceRange, BOOL *stop) {
NSString *token = [question substringWithRange:tokenRange];
NSLog(@"%@: %@", token, tag); }];

当我运行它时question = @"Weekend in New York","New York"标记为PlaceName哪个是伟大的.但是,当我跑这跟question = @"Weekend in new york","new"被标记为"Adjective"与"york"被标记为PlaceName.有没有办法解决这个问题,"New …

我刚开始学习服务器,而且我正在搞乱谷歌的App Engine.我试图通过位于App Engine的教程,让这里在Mac上使用Eclipse,但我得到读取一个问题:

现在,我在标签的根视图的viewDidLoad中设置标题,只有在我单击选项卡时才会更改标题.我想在选择标签之前设置它.我尝试过类似的东西:

[[self.parentViewController.tabBarController.tabBar.items objectAtIndex:2] title] = @"string";

在第一个视图中加载另一个选项卡,但显然有一些错误,因为我得到一个左操作数错误.

有人能告诉我实现我想做的正确方法吗？

谢谢!!

我问,因为我现在拥有它的方式似乎很奇怪.基本上,我说,"如果抛出异常,就做点什么.不过,什么都不做." 以下是一些示例代码:

 try:
        db.get(db.Key(uid))
 except:
        newUser = User(key_name=str(uid)) 
        newUser.first_name = self.request.get("first")
        newUser.last_name = self.request.get("last")
        newUser.email = self.request.get("email") 
        newUser.phone = self.request.get("phone")
        db.put(newUser)

谢谢!
