NSSearchFiled辞职第一响应者

Question

我有以下代码片段以编程方式创建NSSearchField

mysearchField = [ [ NSSearchField alloc ] init];
[[mysearchField cell] setPlaceholderString:@"Page Number & Press Enter"];
[myView addSubview: mysearchField ];
    [mysearchField resignFirstResponder];
[mysearchField release];
[mysearchField setDelegate:self];

这里我试图将resignFirstResponder转换为mysearchField，但是mysearchField仍然专注于应用程序启动。

我错过了什么吗

Answer 1

[myView.window makeFirstResponder:nil];永远不要直接调用resignFirstResponder。
