模态定制表不打烊

Question

我想显示自定义模式对话框，并做了以下方法：

EncPasswordSheet是IBOutlet中NSWindow的*类型。

@implementation EncryptionPasswordSheet 
-(id)init  
{  
    return self;  
} 

- (void)showCustomDlg:(NSWindow *)window 
{  
    if (!EncPasswordSheet)  
    {   
     [NSBundle loadNibNamed: @"EncryptionPasswordDlg" owner: self]; 
    }   
    [NSApp beginSheet:EncPasswordSheet modalForWindow:window modalDelegate:nil didEndSelector:nil contextInfo:nil];  
    [NSApp runModalForWindow: EncPasswordSheet];   
    [NSApp endSheet: EncPasswordSheet];  
    [EncPasswordSheet orderOut: self];  
} 

- (IBAction)getPasswordFromSheet:(id)sender 
{ 
    password = [passwordField stringValue]; 
    [NSApp stopModal];  
} 

- (IBAction)cancelEncPasswordSheet:(id)sender  
{  
    password = nil;  
    [NSApp stopModal];   
} 

@end 

正在显示对话框并接受输入。在按下“ok”或“cancel”时，相应的IBAction方法正在执行并且程序继续。问题在于对话框并未避开 - 即没有关闭或消失。

我想你应该叫由你确定叫IBActions endSheet和取消按钮，我以为是getPasswordFromSheet和cancelEncPasswordSheet：

- (void)showCustomDlg:(NSWindow *)window { 
    if (!EncPasswordSheet) { 
     [NSBundle loadNibNamed: @"EncryptionPasswordDlg" owner: self]; 
    } 

    [NSApp beginSheet:EncPasswordSheet 
     modalForWindow:window modalDelegate:nil 
     didEndSelector:nil contextInfo:nil]; 
} 

- (IBAction)getPasswordFromSheet:(id)sender { 
    password = [passwordField stringValue]; 
    [EncPasswordSheet orderOut: self]; 
    [NSApp endSheet: EncPasswordSheet]; 
} 

- (IBAction)cancelEncPasswordSheet:(id)sender { 
    password = nil; 
    [EncPasswordSheet orderOut: self]; 
    [NSApp endSheet: EncPasswordSheet]; 
}

你有没有选中“可见在启动”在Interface Builder的对话窗口？因为如果我不这样做，那么对话框就不会作为工作表应用，并且在完成时不关闭。试试你的原始代码。
