27 | 28 | 1. 用 `initWithTextField:` 方法初始化 **_formatter** : 29 | 30 | _formatter = [[WKTextFieldFormatter alloc] initWithTextField:_textField]; 31 | 32 | 1. 设置 **_formatter** 的 __formatterType__ : 33 | 34 | typedef NS_ENUM(NSUInteger, WKFormatterType) { 35 | WKFormatterTypeAny, //不过滤 36 | WKFormatterTypePhoneNumber, //11位电话号码 37 | WKFormatterTypeNumber, //数字 38 | WKFormatterTypeDecimal, //小数,默认精确到点后两位 39 | WKFormatterTypeAlphabet, //英文字母 40 | WKFormatterTypeNumberAndAlphabet, //数字+英文字母 41 | WKFormatterTypeIDCard, //18位身份证 42 | WKFormatterTypeCustom //自定义 43 | }; 44 | 45 | 46 | 例如: 47 | 48 | _formatter.formatterType = WKFormatterTypePhoneNumber; 49 | 50 | __搞定咯。__ 51 | 52 | ##自行设置字符集 53 | 除了选择 __WKFormatterTypeCustom__ , 还要把 __characterSet__ 设置为你想要的字符集，例如： 54 | 55 | ``` 56 | _formatter.characterSet = @"iWant"; 57 | ``` 58 | 59 | ##限制输入长度 60 | 设置 __limitedLength__ 即可： 61 | 62 | ``` 63 | _formatter.limitedLength = 8; 64 | ``` 65 | 66 | ##小数精确度 67 | 默认精确到小数点后一位，可自行设置 __decimalPlace__ ： 68 | 69 | ``` 70 | _formatter.decimalPlace = 2; 71 | ``` 72 | 73 | ##License 74 | WKTextFieldFormatter is released under [__MIT License__](https://github.com/WelkinXie/WKTextFieldFormatter/blob/master/LICENSE). -------------------------------------------------------------------------------- /WKTextFieldFormatter.podspec: -------------------------------------------------------------------------------- 1 | #WKTextFieldFormatter.podspec 2 | Pod::Spec.new do |s| 3 | s.name = "WKTextFieldFormatter" 4 | s.version = “2.0” 5 | s.summary = "Easily block the unwanted input to the textField." 6 | s.homepage = "https://github.com/WelkinXie/WKTextFieldFormatter" 7 | s.license = 'MIT' 8 | s.author = { "Welkin Xie" => "welkin995@126.com" } 9 | s.platform = :ios, "7.0" 10 | s.ios.deployment_target = "7.0" 11 | s.source = { :git => "https://github.com/WelkinXie/WKTextFieldFormatter.git", :tag => s.version} 12 | s.source_files = 'WKTextFieldFormatter/WKTextFieldFormatter/*.{h,m}' 13 | s.requires_arc = true 14 | end -------------------------------------------------------------------------------- /WKTextFieldFormatter.xcodeproj/project.pbxproj: -------------------------------------------------------------------------------- 1 | // !$*UTF8*$! 2 | { 3 | archiveVersion = 1;
