最全,可直接用的一些正则校验,判断邮箱,手机号码,车牌号,身份证号,网址,账号,密码,ip,去掉html格式,工商税号等。

一些正则校验,判断邮箱,手机号码,车牌号,身份证号,网址,账号,密码,ip,去掉html格式,工商税号等。

// 判断邮箱
isValid = [text isValidEmail];
// 判断手机号码
isValid = [text isValidPhoneNum];
// 判断ip
isValid = [text isValidIP];
// 判断身份证号
isValid = [text isValidIdCardNum];
// 判断账号
isValid = [text isValidWithMinLenth:4 maxLenth:12 containChinese:NO firstCannotBeDigtal:YES];
// 去掉html格式
text = [text removeHtmlFormat];
// 工商税号
isValid = [text isValidTaxNo];
