问题 How to change windows blink cursor shape from vertical which is by default ( | ) to horizontal like that used in dos ( _ ). Is there some good function that take care about that?

What will a SQLiteCursor do if a column is null?

阅读更多关于 What will a SQLiteCursor do if a column is null?

问题 I want to get an integer from a Cursor returned from a SQLite query, but I know the integer may be null. Unfortunately I can't find any Cursor method allowing me to check this.

Unfortunately, the

阅读更多关于 Text selection not happening properly because of custom line spacing in UITextView

问题 I have a custom UITextView with custom line spacing applied. When I try to select the text the selectionRect is wrong.
