列出iPhone上的所有Info.plist文件？

Question

在ios世界中有没有办法通过objective-c列出所有已安装的应用Info.plist文件？如果可能，如何读取每个Info.plist文件的属性？我使用下面的代码，但它只显示扫描开始和扫描结束。

 - (void)scan
   {
    NSString *pathOfApplications = @"/var/mobile/Applications";

    NSLog(@"scan begin");

    // all applications
    NSArray *arrayOfApplications = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:pathOfApplications error:nil];
    for (NSString *applicationDir in arrayOfApplications) {
        // path of an application
        NSString *pathOfApplication = [pathOfApplications stringByAppendingPathComponent:applicationDir];
        NSArray *arrayOfSubApplication = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:pathOfApplication error:nil];
        // seek for *.app
        for (NSString *applicationSubDir in arrayOfSubApplication) {
            if ([applicationSubDir hasSuffix:@".app"]) {// *.app
                NSString *path = [pathOfApplication stringByAppendingPathComponent:applicationSubDir];

                path = [path stringByAppendingPathComponent:@"Info.plist"];

                // so you get the Info.plist in the dict
                NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:path];
                // code to analyzing the dict.
            }
        }
    }

    NSLog(@"scan end");
   }
