iOS密码框实现(二)取消确定按钮

由于将确定按钮去掉了,所以需要重新修改下代码,当输入第四个数字时,自动进入房间。

实现方式:
 
首先声明一个block初始化方法,因为这只是个框框,并不需要处理网络请求等等,需要提供一个block给调用方,调用方利用block 去拿到密码,利用密码做一些开房间等操作。
 
利用计时器通过0.2秒来看清输入第四位密码,用户输入4位密码后自动进入下一步操作。
 
1.头文件需要定义:
 
@classIDSGameRoomSecretView;

typedefvoid(^selfhandleInputPasswordBlock)(NSString *password ,IDSGameRoomSecretView *secretView);

@interface IDSGameRoomSecretView : UIView

- (
instancetype)initWithselfPasswordCallBack:(selfhandleInputPasswordBlock)passwordCallback;

/**
 * 
弹出密码框视图
 */

- (
void)showInputSecretView;

/**
 * 
移除密码框view 通过外部通过block来移除
 */

- (
void)removeView;

/**
 * 
重置密码操作
 */

-(
void)resetTextField;

@end

2.初始化操作:
 
 
- (instancetype)initWithselfPasswordCallBack:(selfhandleInputPasswordBlock)passwordCallback
{
   
if (self = [superinit]) {
       
self.onselfHandlePasswordCallBack = passwordCallback;
    }
   
   
returnself;
}
.
3.建立密码框View
 
Ps:通过4个UITextField 来声明4个密码框,
 
- (void)showInputSecretView
{

   
self.backgroundColor = [UIColorcolorWithRed:0green:0blue:0alpha:0.7];
    [[
AppDelegatemainWindow] addSubview:self];
    [
self.inputViewbecomeFirstResponder];
   
   
self.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
   
   
UITapGestureRecognizer *selfRecognizer = [[UITapGestureRecognizeralloc] initWithTarget:selfaction:@selector(removeView)];
   
self.userInteractionEnabled = YES;
    [
selfaddGestureRecognizer:selfRecognizer];
    selfRecognizer.
delegate = self;
   
   
self.secretRoomView = [[UIViewalloc] initWithFrame:CGRectMake(0, 0, 510/2, 290/2)];
   
self.secretRoomView.backgroundColor = [UIColorwhiteColor];
   
self.secretRoomView.centerX = SCREEN_WIDTH/2;
   
self.secretRoomView.centerY = SCREEN_HEIGHT/2-50;
 
   
_titleLabel = [[UILabelalloc] initWithFrame:CGRectMake(0, 50/2, 0, 0)];
   
_titleLabel.text = @"房间已加锁";
   
_titleLabel.textColor = NF_Color_C3;
   
_titleLabel.font = [UIFontsystemFontOfSize:Near_Final_Font_T6];
    [
_titleLabelsizeToFit];
   
_titleLabel.centerX = self.secretRoomView.frame.size.width/2;
    [
self.secretRoomViewaddSubview:_titleLabel];
   
   
_subtitleLabel = [[UILabelalloc] initWithFrame:CGRectMake(0,CGRectGetMaxY(self.titleLabel.frame)+10, 0, 0)];
   
_subtitleLabel.text = @"输入房间密码";
   
_subtitleLabel.textColor = NF_Color_C10;
   
_subtitleLabel.font = [UIFontsystemFontOfSize:Near_Final_Font_T9];
    [
_subtitleLabelsizeToFit];
   
_subtitleLabel.centerX = self.secretRoomView.frame.size.width/2;
    [
self.secretRoomViewaddSubview:_subtitleLabel];
   
   
self.textFieldArray = [NSMutableArrayarray];
   
NSArray *views = [selfsubviews];
   
for (UITextField *tf in views) {
        [tf
removeFromSuperview];
    }
   
   
for (int i=0;i<4;++i) {
       
PZXVerificationTextField *tf = [[PZXVerificationTextFieldalloc] initWithFrame:CGRectMake(70/2+i*70/2+15*i, CGRectGetMaxY(self.subtitleLabel.frame)+15, 70/2, 70/2)];
        [tf
setFont:[UIFontsystemFontOfSize:Near_Final_Font_T5]];
        [tf
setTextColor:NF_Color_C4];
        tf.
backgroundColor = [UIColorclearColor];
        tf.
layer.borderWidth = 0.5;
        tf.
layer.borderColor = NF_Color_C9.CGColor;
        tf.
layer.cornerRadius = 5.f;
        tf.
layer.masksToBounds = YES;
        tf.
tintColor =[UIColorclearColor];
        //苹果文档上提到过一次,tag值较小的,如0-100为苹果保留使用,0就是保留着给自己这个view使用的
        tf.
tag = 100+i;
        tf.
keyboardType = UIKeyboardTypeNumberPad;
        tf.
textAlignment = NSTextAlignmentCenter;
        tf.
delegate = self;
        tf.
pzx_delegate = self;
        [
self.secretRoomViewaddSubview:tf];
        [
self.textFieldArraycl_addObject:tf];
        [tf
becomeFirstResponder];
    }
   
    [
selfaddSubview:self.secretRoomView];
   
   
self.secretRoomView.layer.cornerRadius = 10.f;
   
self.secretRoomView.layer.masksToBounds = YES;
}
 
.
4. 移除View
 
//移除密码框View
- (
void)removeView
{
    [
selfremoveFromSuperview];
}

.
5. TextField输入字符代理方法
 
//通过TextField代理来控制不同textfield字符的添加以及删除,以及判断第4Textfield自动调用成功block方法
-(
BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
   
    textField.
text = string;
  
   
if (textField.text.length > 0) {
       
       
if (textField.tag<  [[_textFieldArraylastObject] tag]) {
           
           
UITextField *newTF =  (UITextField *)[selfviewWithTag:textField.tag+1];
           
            [newTF
becomeFirstResponder];
        }
    }
   
   
for (UITextField *tf inself.textFieldArray) {
       
if([tf.textisEqualToString:@""]) {
           
returnNO;
        }
    }

   
if (![_queryNoticeTimerisValid]) {
        [
selfstartQueryTimer];
    }
   
returnNO;
}
.
6. TextField输入删除键删除字符代理
//点击退格键的代理
#pragma mark - PZXTextFieldDelegate
-(void)PZXTextFieldDeleteBackward:(PZXVerificationTextField *)textField{
   
   
if (textField.tag > [[_textFieldArrayfirstObject] tag]) {
       
       
UITextField *newTF =  (UITextField *)[selfviewWithTag:textField.tag-1];
        newTF.
text = @"";
        [newTF
becomeFirstResponder];
    }  
}
.
7. 重置密码
-(void)resetTextField{
   
   
for (UITextField *tf inself.textFieldArray) {
        tf.
text = @"";
        [tf
resignFirstResponder];
    }
    [[
_textFieldArrayfirstObject] becomeFirstResponder];
}
.
8.获取密码,进入block操作
 
-(void)getVertificationCode{ //获取密码方法
   
   
NSString *str = [NSStringstring];
   
   
for (int i = 0; i<_textFieldArray.count; i++) {
        str = [str
stringByAppendingString:[NSStringstringWithFormat:@"%@",(UITextField *)[_textFieldArray[i] text]]];
    }
   
if (self.onHandlePasswordCallBack) {
       
self.onHandlePasswordCallBack(str);
    }
   
if (self.onselfHandlePasswordCallBack) {
       
self.onselfHandlePasswordCallBack(str,self);
    }
    [
selfstopQueryTimer];
}
.
9.手势操作
 
-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
   
   
for (UITextField *tf inself.textFieldArray) {
       
        [tf
resignFirstResponder];
    }
}



- (
BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
   
if ([touch.viewisDescendantOfView:self.secretRoomView]) {
       
returnNO;
    }
   
returnYES;
}
.
10.计时器操作
 
Ps: 计时器的作用是防止密码输入到第四个字母时,用户来不及看清第四个字母,就直接进入房间操作,所以利用计时器,0.2秒才会进入下一步操作,让用户在0.2秒内看到输入第4位密码。
 
- (void)startQueryTimer
{
    [
selfstopQueryTimer];
   
   
if (nil == _queryNoticeTimer) {
       
_queryNoticeTimer = [NSTimerscheduledTimerWithTimeInterval:sIntervalTime
                                                            
target:self
                                                          
selector:@selector(getVertificationCode)
                                                          
userInfo:nilrepeats:NO];
    }
}

- (
void)stopQueryTimer
{
   
if (self.queryNoticeTimer) {
       
        [
self.queryNoticeTimerinvalidate];
       
_queryNoticeTimer = nil;
    }
}
