iOS开发 验证手机、邮箱是否填写正确

有时候我们需要判断填写的用户手机号码、邮箱等信息是否出错并作出提示，这里我列举一些常用的方法供给大家探讨使用。

正则判断手机号码地址格式

- (BOOL)isMobileNumber:(NSString*)mobileNum {

NSString*MOBILE =@"^1(3[0-9]|4[57]|5[0-35-9]|8[0-9]|7[06-8])\\d{8}$";

NSPredicate*regextestmobile = [NSPredicatepredicateWithFormat:@"SELF MATCHES %@", MOBILE];

return[regextestmobileevaluateWithObject:mobileNum];

}

邮箱判断

+ (BOOL) validateEmail:(NSString *)email{

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:email];

}

验证身份证号码

+ (BOOL) validateIdentityCard: (NSString *)identityCard

{

BOOL flag;

if (identityCard.length <= 0) {

flag = NO;

return flag;

}

NSString *regex2 = @"^(\\d{14}|\\d{17})(\\d|[xX])$";

NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];

return [identityCardPredicate evaluateWithObject:identityCard];

}
