CBAutocompleteTextField 子类 NSTextField 并重写该方法:
- (void)textDidChange:(NSNotification *)aNotification
{
[self complete:nil];
[super textDidChange:aNotification];
}
我没有收到任何警告，但出现运行时错误:
[CBAutocompleteTextField complete:]: unrecognized selector sent to instance 0xca19a50
NSTextField 是 NSResponder 的子类，它提供了这种方法。事实上我没有收到警告。
谢谢
最佳答案
根据文档，除非您提供覆盖，否则该方法将不起作用:
This method can be interpreted, for example, as a request to attempt expansion of a partial word, such as for expanding a glossary shortcut, or to close a graphics item being drawn.
NSResponderdeclares but doesn’t implement this method. (emphasis added)
