ios - 如何将 NSUUID 表示为字符串？

Question

如何将 NSUUID 转换为 NSString？

NSString *url = [self mysql_process:ESTIMOTE_PROXIMITY_UUID];

- (NSString*)mysql_process:(NSUUID *)beacon_id
{

    NSString *strURL = [NSString stringWithFormat:@"http://path_to_php_file/mysql.php?id=%@", beacon_id];
    NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];
    NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];

    return strResult;

}

当我尝试NSLog URL时，我得到一个指针，它显示了我的NSUUID，ESTIMOTE_PROXIMITY_UUID在这种情况下。

NSUUID有一个方法:-(NSString*)UUIDString; 。所以:

NSString *uuidString = [yourNSUUID UUIDString]
