阅读Developer Library的文档,doc的标识符是" com.microsoft.word.doc ".但是docx的标识符是什么？

XCode:4.6 Lion:10.8 IOS 6.1错误:SBTarget无效,如何解决？

首先，展示我的个人资料。

sudo profiles show -type enrollment\n

/bin/bash a.sh

它成功了.

但是当我想跑的时候

/bin/bash a.sh > a_info.txt

    NSString *finalPath = [docPath stringByAppendingPathComponent:name];
    [fileManager createDirectoryAtPath:finalPath withIntermediateDirectories:YES attributes:nil error:nil];
    return finalPath;
}
//below is how to use NSData writeToFile

    success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
    img.image = image;

    NSData *imageData = UIImagePNGRepresentation(img.image);
