我有一个UITextView,并使用其tokenizer来检查用户点击的单词.
我的目标是改变tokenizer所认为的单词.目前似乎将单词定义为连续的字母数字字符,我希望将单词定义为不是空格字符("")的连续字符.
例如:'foo-bar','foo/bar'和'foo @@ bar'目前都将被视为两个单独的单词('foo'和'bar'),但我希望它们都被视为单个单词单词(因为它们都不包含空格).
该文档讨论了UITextInputStringTokenizer类的子类化,但我找不到某个人这样做的例子,我无法弄清楚如何实现所需的方法:
func isPosition(position: UITextPosition, atBoundary granularity: UITextGranularity, inDirection direction: UITextDirection) -> Bool
func isPosition(position: UITextPosition, withinTextUnit granularity: UITextGranularity, inDirection direction: UITextDirection) -> Bool
func positionFromPosition(position: UITextPosition, toBoundary granularity: UITextGranularity, inDirection direction: UITextDirection) -> UITextPosition?
func rangeEnclosingPosition(position: UITextPosition, withGranularity granularity: UITextGranularity, inDirection direction: UITextDirection) -> UITextRange?
