Question

我想在我的应用程序中添加密码锁...
我创建了视图，但我不知道如何让它工作......

这是我必须做的事情：
- 如果用户正在设置其密码，则必须键入两次，并且代码必须验证第二次输入的密码是否与第一次相同。
- 如果设置视图调用密码控制器（例如，设置密码），则导航栏上必须有取消按钮，但如果在应用启动时调用，则不能启用取消按钮。

summaryLabel是显示“密码不匹配”等消息的标签。请重试。当密码与先前写入或保存的密码不同时。

EDIT1：如何使用textField：shouldChangeCharactersInRange：replacementString方法执行此操作？

这是代码：

#import "PasscodeController.h"

@implementation PasscodeController

@synthesize panelView;
@synthesize summaryLabel;
@synthesize titleLabel;
@synthesize textField1;
@synthesize textField2;
@synthesize textField3;
@synthesize textField4;
@synthesize hiddenTF;

-(void)viewDidLoad {
self.title = @"Passcode"; 
self.view.backgroundColor = [UIColor groupTableViewBackgroundColor];
titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(25, 22, 270, 30)];
titleLabel.font = [UIFont boldSystemFontOfSize:15];
titleLabel.textAlignment = UITextAlignmentCenter;
titleLabel.textColor = [UIColor colorWithRed:66.0/255.0 green:85.0/255.0 blue:102.0/255.0 alpha:1.0];
titleLabel.backgroundColor = [UIColor clearColor];
[self.view addSubview:titleLabel];
[titleLabel release];

summaryLabel = [[UILabel alloc] initWithFrame:CGRectMake(25, 130, 270, 40)];
summaryLabel.font = [UIFont boldSystemFontOfSize:12];
summaryLabel.numberOfLines = 0;
summaryLabel.baselineAdjustment = UIBaselineAdjustmentNone;
summaryLabel.textAlignment = UITextAlignmentCenter;
summaryLabel.textColor = [UIColor colorWithRed:66.0/255.0 green:85.0/255.0 blue:102.0/255.0 alpha:1.0];
summaryLabel.backgroundColor = [UIColor clearColor];
[self.view addSubview:summaryLabel];
[summaryLabel release];

textField1 = [[UITextField alloc] initWithFrame:CGRectMake(25, 60, 60, 60)];
textField1.borderStyle = UITextBorderStyleBezel;
textField1.textColor = [UIColor blackColor];
textField1.textAlignment = UITextAlignmentCenter;
textField1.font = [UIFont systemFontOfSize:41];
textField1.secureTextEntry = YES;
textField1.backgroundColor = [UIColor whiteColor];
textField1.keyboardType = UIKeyboardTypeNumberPad;
[self.view addSubview:textField1];
[textField1 release];

textField2 = [[UITextField alloc] initWithFrame:CGRectMake(95, 60, 60, 60)];
textField2.borderStyle = UITextBorderStyleBezel;
textField2.textColor = [UIColor blackColor];
textField2.textAlignment = UITextAlignmentCenter;
textField2.font = [UIFont systemFontOfSize:41];
textField2.secureTextEntry = YES;
textField2.backgroundColor = [UIColor whiteColor];
textField2.keyboardType = UIKeyboardTypeNumberPad;
[self.view addSubview:textField2];
[textField2 release];

textField3 = [[UITextField alloc] initWithFrame:CGRectMake(165, 60, 60, 60)];
textField3.borderStyle = UITextBorderStyleBezel;
textField3.textColor = [UIColor blackColor];
textField3.textAlignment = UITextAlignmentCenter;
textField3.font = [UIFont systemFontOfSize:41];
textField3.secureTextEntry = YES;
textField3.backgroundColor = [UIColor whiteColor];
textField3.keyboardType = UIKeyboardTypeNumberPad;
[self.view addSubview:textField3];
[textField3 release];

textField4 = [[UITextField alloc] initWithFrame:CGRectMake(235, 60, 60, 60)];
textField4.borderStyle = UITextBorderStyleBezel;
textField4.textColor = [UIColor blackColor];
textField4.textAlignment = UITextAlignmentCenter;
textField4.font = [UIFont systemFontOfSize:41];
textField4.secureTextEntry = YES;
textField4.backgroundColor = [UIColor whiteColor];
textField4.keyboardType = UIKeyboardTypeNumberPad;
[self.view addSubview:textField4];
[textField4 release];

hiddenTF = [[UITextField alloc] initWithFrame:CGRectZero];
hiddenTF.hidden = YES;
hiddenTF.delegate = self;
hiddenTF.keyboardType = UIKeyboardTypeNumberPad;
[self.view addSubview:hiddenTF];
[hiddenTF release];
[hiddenTF becomeFirstResponder];
}

非常感谢！

如果这对其他人有帮助，我在GitHub上使用此源代码解决了我的问题：PTPasscodeViewController。
我改变它以适应我的需要，现在工作得很好:)

如果您想使用它，有关于如何在项目页面或文件中使用它的所有信息（如果您已下载）;）

希望这有帮助！

P.S。：非常感谢Lasha Dolidze提供此代码！
