我想从url下载xml文件。我将我的xml文件上传到谷歌硬盘并公开分享该文件。
文件内容是
<testapp><welcomePage><logoimage>mspeller</logoimage>
<titleBackgroudColor>yellow</titleBackgroudColor><aboutUsIcon>Speller</aboutUsIcon><allitemIcon>Speller</allitemIcon><welBackgroundcolor>red</welBackgroundcolor>
</welcomePage>
<user><userName>mgdan</userName><firstName>Mila</firstName><lastName>Gdan</lastName>
</user></testapp>
我正在使用网址
下载此文件 NSURL *url = [NSURL URLWithString:@"https://drive.google.com/file/d/0B-3M5xTcGgbLYlAxR1Vqa3dRMkU/edit?usp=sharing"];
NSData *data = [NSData dataWithContentsOfURL:url]; // Load XML data from web
NSString *applicationDocumentsDir =
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *storePath = [applicationDocumentsDir stringByAppendingPathComponent:@"config.xml"];
// write to file atomically (using temp file)
[data writeToFile:storePath atomically:TRUE];
但是下载的xml看起来像这样它从谷歌返回完整的原始数据我正在做错的
