Question

我正在尝试显示自定义模式对话框并按以下方式执行：

EncPasswordSheet是IBOutlet NSWindow *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“确定”或“取消”时，正在执行相应的IBAction方法并继续执行程序。问题是对话框不会偏离 - 即它没有被关闭或消失。

Answer 1

您是否在Interface Builder中为对话框窗口取消选中“Visible At Launch”？因为如果我不这样做，那么对话框不会作为工作表显示，并且在完成时不会关闭。尝试使用原始代码。

Answer 2

我认为您应该通过“确定”和“取消”按钮调用IBActions调用endSheet，我认为这些按钮为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];
}

模态自定义表未关闭
