現(xiàn)在大部分的app可能都會(huì)碰到自定義鍵盤這種需求，特別是一些金融類的APP，在涉及到輸入金額的時(shí)候，都會(huì)用到自定義鍵盤。今天就封裝了一個(gè)仿支付寶的支付數(shù)字鍵盤，并且提供了更多供用戶自定義的接口，用戶可自定義鍵盤大部分內(nèi)容。如背景色，字體顏色，return鍵的回調(diào)，輸出內(nèi)容格式（如000.00）等
邏輯圖如下：

使用方法：

1.屬性

/// 文本框
@property (nonatomic, weak) UITextField *textFiled;
/// 點(diǎn)擊確定回調(diào)block
@property (nonatomic,copy) ConfirmBlock confirmClickBlock;
/// 鍵盤背景色
@property (nonatomic,strong) UIColor *bgColor;
/// 鍵盤數(shù)字背景色
@property (nonatomic,strong) UIColor *keyboardNumBgColor;
/// 鍵盤文字顏色
@property (nonatomic,strong) UIColor *keyboardTitleColor;
/// 間隔線顏色
@property (nonatomic,strong) UIColor *marginColor;
/// return鍵被背景色
@property (nonatomic,strong) UIColor *returnBgColor;
/// return鍵文字顏色
@property (nonatomic,strong) UIColor *returnTitleColor;
/// return鍵title
@property (nonatomic,strong) NSString *title;
/// 輸出內(nèi)容格式（00000.00）
@property (nonatomic,strong) NSString *formatString;
/// 繪制鍵盤
- (void)drawKeyboard;

2.簡(jiǎn)單使用

- (void)showMoneyKeyboard
{
    YLNumberKeyboard *keyboard = [[YLNumberKeyboard alloc]init];
    // 指定哪個(gè)textfield需要彈出數(shù)字鍵盤
    keyboard.textFiled = self.textField;
    self.textField.inputView = keyboard;
    // 個(gè)性化設(shè)置鍵盤
    keyboard.bgColor = YLRandomColor;
    keyboard.returnBgColor = YLRandomColor;
    keyboard.returnTitleColor = YLRandomColor;
    keyboard.formatString = @"000.000";
    __weak YLNumberKeyboard *keyboard1 = keyboard;
    keyboard.confirmClickBlock = ^{
       UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:[NSString stringWithFormat:@"要求的格式為%@  輸入的數(shù)字為%@",keyboard1.formatString,self.textField.text] preferredStyle:UIAlertControllerStyleAlert];
        UIAlertAction *action = [UIAlertAction actionWithTitle:@"確定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            
        }];
        [alert addAction:action];
        [self presentViewController:alert animated:YES completion:^{
            
        }];
    };
    // 繪制鍵盤
    [keyboard drawKeyboard];
    
}
