连续检查两个 NSSecureTextField

Question

我怎样才能做到一直检查 2 个 NSSecureTextFields 以了解它们是否相同/不同以显示图像而不需要按钮？

.h 文件：

IBOutlet NSSecureTextField *textField;
IBOutlet NSSecureTextField *textField2;
IBOutlet NSImageView *imagem;
}

- (IBAction)verificarPass:(id)sender; 

.m 文件：

- (IBAction)verificarPass:(id)sender;
{
    NSString *senha1 = [textField stringValue];
    NSString *senha2 = [textField2 stringValue];
    NSImage *certo;
    NSImage *errado;
    certo = [NSImage imageNamed:@"Status_Accepted.png"];
    errado = [NSImage imageNamed:@"Error.png"];

    if ([senha1 isEqualToString:senha2]) {
[imagem setImage:certo];
}else{
    [imagem setImage:errado];
}
}

将目标方法添加到 textField 控件，由 UIControlEventEditingChanged 控件事件触发：

[textField addTarget:self action:@selector(verificarPass:) forControlEvents:UIControlEventEditingChanged];
