NSWindowController 多个窗口之间传递值
主界面一个按钮点击,出现另一个窗口,然后输入123,点OK,在主界面的编辑框内可以得到123这个值,
思路:
由于要给主界面的控件赋值,所以在第二个窗口里面设定一个同类型的变量。
然后主界面的控件 = 第二个窗口的同类型变量。
例如:主界面是
NSTextField 控件1,
那么就在子窗口里面设定这样一个变量(NSTextField a1),给值。
然后在主界面调用时,让主界面的NSTextField 控件1 =a1
这样主界面就可以得到子界面的值了。
子界面代码如下
H文件
// // Form1.h // test_multi_window // // Created by EDU on 3/6/14. // Copyright (c) 2014 EDU. All rights reserved. // #import <Cocoa/Cocoa.h> @interface Form1 : NSWindowController @property (assign) IBOutlet NSWindow *window_form1; @property (assign) NSInteger *button_ok_flag; @property (assign) NSString *button_string; @property (assign) IBOutlet NSTextField *m_Edit1; @property (assign) IBOutlet NSTextField *form_main; @property (assign) IBOutlet NSTextField *form_main_m_ET1; @property bool form_ok_cancel_result; -(void)get_value; @end
M文件
// // Form1.m // test_multi_window // // Created by on 3/6/14. // Copyright (c) 2014 EDU.

主窗口代码如下
H文件
// // EDUAppDelegate.h // test_multi_window // // Created by on 3/6/14. // Copyright (c) 2014 EDU.

M文件
// // EDUAppDelegate.m // test_multi_window // // Created by EDU on 3/6/14. // Copyright (c) 2014 EDU. All rights reserved. // #import "EDUAppDelegate.h" @implementation EDUAppDelegate @synthesize m_form1; @synthesize m_label1; @synthesize window; @synthesize m_ET1; - (void)dealloc { [super dealloc]; } - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { // Insert code here to initialize your application } - (IBAction)OnBT_Form1:(id)sender { if(!m_form1) { m_form1 = [[Form1 alloc] initWithWindowNibName:@"Form1"]; } m_form1.window.title = @"Hello,this is a test"; m_form1.form_main = m_label1; m_form1.form_main_m_ET1=m_ET1; [m_form1 showWindow: sender]; } @end
运行编译OK
如图:
完成!
