    }

    if ([pred evaluateWithObject:str]) {
        return YES;
    }
    return NO;
}

iOS 判断邮箱

- (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];

}

空字符串
