一、概念

在外界直接一行代码实现

///MARK:- 实例化一个密码显示view

- (void)addPasswordTextView:(CGRect)frame {

_passwordTextView = [[SHPasswordTextView alloc]initWithFrame:frame count:6 margin:20 passwordFont:50 forType:SHPasswordTextTypeRectangle block:^(NSString * _Nonnull passwordStr) {

NSLog(@"shihu___passwordStr == %@",passwordStr);

}];

//_passwordTextView.passwordSecureEntry = YES;//安全密码

[self.view addSubview:_passwordTextView];

}

选择样式:

//提供5种样式展示

typedef NS_ENUM(NSInteger, SHPasswordTextType){

SHPasswordTextTypeNormal = 1 << 0, /**默认 __*/

SHPasswordTextTypeAnimation_line = 1 << 1, /**line动画__*/

SHPasswordTextTypeAnimation_font = 1 << 2, /**字体动画__*/

SHPasswordTextTypeAnimation_lineAndFont = 1 << 3, /**line和字体动画__*/

SHPasswordTextTypeRectangle = 1 << 4 /**方块形☐☐*/

};
