How can I make TAB exit the NSTextView, while keeping the newline behaviour of the Enter key?

推荐答案

您可以实现 -textView：doCommandBySelector： / code>在您的文本视图的委托：

You could implement -textView:doCommandBySelector: in your text view's delegate:

- (BOOL)textView:(NSTextView *)aTextView doCommandBySelector:(SEL)aSelector {
    if (aSelector == @selector(insertTab:)) {
        [[aTextView window] selectNextKeyView:nil];
        return YES;
    }

    return NO;
}
