iOS 验证邮箱手机号格式

做登录界面时，用户在UITextfield中输入输入邮箱账号后，我们应该在本地验证格式是否正确，再将参数传给服务器验证。

最简单的就是利用系统的NSPredicate

//利用正则表达式验证

-(BOOL)isValidateEmail:(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];

}
