开发中有时候我们会遇到验证用户的各种信息格式是否正确,这个时候我们客户端就要使用正则表达式来验证。
邮箱验证:
- (BOOL)isValidEmail;
- (BOOL)isValidEmail
{
NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:self];
}
手机号验证:(手机号码验证可以再次细分为移动联通电信,再此则不再累述)
- (BOOL)isValidPhoneNum
{
//手机号以13, 15,18开头,八个 \d 数字字符
NSString *phoneRegex = @"^((13[0-9])|(147)|(15[^4,\\D])|(17[0-9])|(18[0,0-9]))\\d{8}$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
return [phoneTest evaluateWithObject:self];
}
车牌号验证:
- (BOOL)isValidCarNo
{
NSString *carRegex = @"^[A-Za-z]{1}[A-Za-z_0-9]{5}$";
NSPredicate *carTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",carRegex];
return [carTest evaluateWithObject:self];
}
网址验证:
- (BOOL)isValidUrl
{
NSString *regex = @"^((http)|(https))+:[^\\s]+\\.[^\\s]*$";
return [self isValidateWithRegex:regex];
}
邮政编码:
- (BOOL)isValidPostalcode {
NSString *phoneRegex = @"^[0-8]\\d{5}(?!\\d)$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
return [phoneTest evaluateWithObject:self];
}
纯汉字:
- (BOOL)isValidChinese;
{
NSString *phoneRegex = @"^[\u4e00-\u9fa5]+$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
return [phoneTest evaluateWithObject:self];
}
身份证验证:
- (BOOL)isValidIdCardNum
{
NSString *value = [self copy];
value = [value stringByReplacingOccurrencesOfString:@"X" withString:@"x"];
value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
