iOS 判断邮箱格式是否正确

判断邮箱格式是否正确：

-(BOOL)isValidateEmail:(NSString*) email 
{
    NSString* emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-
z0-9.-]+\\.[A-Za-z]{2,4}";
    NSPredicate*emailTest=[NSPredicate predicateWithFormat: @"SELFMATCHES%@", emailRegex];
  return [emailTest evaluateWithObject: email];
}

希望对你有帮助！
