Question

我正在尝试获取iPhone上所有已安装应用程序的列表（越狱），然后在带有图标的UITableView中列出它们......是否可能？感谢

他们是一种检查是否安装了应用程序的方法。有时您可能想要检查设备上是否安装了特定的应用程序，以防您使用需要安装其他应用程序的自定义URL方案（您可能只是灰显/禁用某些按钮）。不幸的是，Apple显然没有任何功能可以为你检查这个，所以我鞭打了一个。它不会枚举每个应用程序，而是使用MobileInstallation缓存，它始终与SpringBoard保持同步，并保存所有已安装应用程序的信息词典。虽然你不是“应该”访问缓存，但它可以读取我的App Store应用程序。这是我的代码，至少与模拟器完美配合：

        // Declaration
        BOOL APCheckIfAppInstalled(NSString *bundleIdentifier); // Bundle identifier (eg. com.apple.mobilesafari) used to track apps

            // Implementation

        BOOL APCheckIfAppInstalled(NSString *bundleIdentifier)
        {
            static NSString *const cacheFileName = @"com.apple.mobile.installation.plist";
            NSString *relativeCachePath = [[@"Library" stringByAppendingPathComponent: @"Caches"] stringByAppendingPathComponent: cacheFileName];
            NSDictionary *cacheDict = nil;
            NSString *path = nil;
                // Loop through all possible paths the cache could be in
            for (short i = 0; 1; i++)
            {

                switch (i) {
                    case 0: // Jailbroken apps will find the cache here; their home directory is /var/mobile
                        path = [NSHomeDirectory() stringByAppendingPathComponent: relativeCachePath];
                        break;
                    case 1: // App Store apps and Simulator will find the cache here; home (/var/mobile/) is 2 directories above sandbox folder
                        path = [[NSHomeDirectory() stringByAppendingPathComponent: @"../.."] stringByAppendingPathComponent: relativeCachePath];
                        break;
                    case 2: // If the app is anywhere else, default to hardcoded /var/mobile/
                        path = [@"/var/mobile" stringByAppendingPathComponent: relativeCachePath];
                        break;
                    default: // Cache not found (loop not broken)
                        return NO;
                    break; }

                BOOL isDir = NO;
                if ([[NSFileManager defaultManager] fileExistsAtPath: path isDirectory: &isDir] && !isDir) // Ensure that file exists
                    cacheDict = [NSDictionary dictionaryWithContentsOfFile: path];

                if (cacheDict) // If cache is loaded, then break the loop. If the loop is not "broken," it will return NO later (default: case)
                    break;
            }

            NSDictionary *system = [cacheDict objectForKey: @"System"]; // First check all system (jailbroken) apps
            if ([system objectForKey: bundleIdentifier]) return YES;
            NSDictionary *user = [cacheDict objectForKey: @"User"]; // Then all the user (App Store /var/mobile/Applications) apps
            if ([user objectForKey: bundleIdentifier]) return YES;

                // If nothing returned YES already, we'll return NO now
            return NO;
        }

以下是此示例，假设您的应用名为“ownmadeapp”，并且是应用商店中的应用。

代码：

        NSArray *bundles2Check = [NSArray arrayWithObjects: @"com.apple.mobilesafari", @"com.yourcompany.yourselfmadeapp", @"com.blahblah.nonexistent", nil];

        for (NSString *identifier in bundles2Check)

        if (APCheckIfAppInstalled(identifier))

        NSLog(@"App installed: %@", identifier);

        else

        NSLog(@"App not installed: %@", identifier);

日志输出：

代码：

        2009-01-30 12:19:20.250 SomeApp[266:20b] App installed: com.apple.mobilesafari

        2009-01-30 12:19:20.254 SomeApp[266:20b] App installed: com.yourcompany.yourselfmadeapp

        2009-01-30 12:19:20.260 SomeApp[266:20b] App not installed: com.blahblah.nonexistent

Answer 2

有可能，只需看看My3G即可。但我不知道该怎么做。

Answer 3

NSString * rootAppPath = @“/ Applications”;

NSArray * listApp = [[NSFileManager defaultManager] contentsOfDirectoryAtPath：rootAppPath error：nil];

的NSLog（@ “％@”，listApp）;

这是获取所有已安装应用程序然后使用此数组在tableview中显示的方法之一

如何在UITableView中列出已安装的应用程序？
