//验证View大小
CGFloat inputViewWidth = codeBgWH * 4 + codeBgPadding *3;
CGFloat inputViewHeight = codeBgWH;


HSFCodeInputView *inputView = [[HSFCodeInputView alloc]initWithFrame:CGRectMake(10, 200, inputViewWidth, inputViewHeight)];

inputView.numberOfVertificationCode = numberOfVertificationCode;

//是否密码模式
//inputView.secureTextEntry = YES;
[self.view addSubview:inputView];

2.如何拿到如何的数据呢？
当输入到最后一位时。可以通过代理拿到输入的数据。
例如：
//（1）.引入 <HSFCodeInputViewDelegate> 代理
@interface ViewController ()<HSFCodeInputViewDelegate>
@end

//（2）创建View,并设置代理
 HSFCodeInputView *inputView = [[HSFCodeInputView alloc]initWithFrame:CGRectMake(10, 200, inputViewWidth, inputViewHeight)];
 //设置代理
 inputView.delegate = self;
 [self.view addSubview:inputView];
 
 //(3)//代理方法回调，拿到数据
-(void)codeInputView:(HSFCodeInputView *)inputView code:(NSString *)code{

NSLog(@"  -----   验证码或者密码是  %@",code);
