我有一个应用程序需要获取设备上已安装（其他可能是第三方）应用程序的列表。怎么做到呢？或者它可以完成吗？

您可以通过Apple私有框架“MobileInstallationInstall”扫描您的所有应用。
方法如下：
NSDictionary *options = [NSDictionary dictionaryWithKeyAndValues:@"ApplicationType",@"Any",nil]
NSDictionary *apps = MobileInstallationLookup(options);
它只能在JB设备中使用。

-(NSArray *) installedApps
{
BOOL isDir enter code here= NO;
NSDictionary *cacheDienter code herect;
NSDictionary *user;
static NSString *const cacheFileName = @"com.apple.mobile.installation.plist";
NSString *relativeCachePath = [[@"Library" stringByAppendingPathComponent: @"Caches"] stringByAppendingPathComponent: cacheFileName];
NSString *path = [[NSHomeDirectory() stringByAppendingPathComponent: @"../.."] stringByAppendingPathComponent: relativeCachePath];
if ([[NSFileManager defaultManager] fileExistsAtPath: path isDirectory: &isDir] && !isDir) // Ensure that file exists
{
cacheDict = [NSDictionary dictionaryWithContentsOfFile: path];
user = [cacheDict objectForKey: @"System"]; // Then all the user (App Store /var/mobile/Applications) apps
}
//NSLog(@"Installed Applications = %@",[user allKeys]);
//return [user allKeys];
return nil;
}
这将使用私有API

苹果没有从iOS设备（iPod Touch / iPhone / iPad）获取此类列表的公共API
答案 3 :(得分：3)
我怀疑是否有可用的东西（如果某些iphone被越狱并且用户可以访问文件系统，那么它将是可能的，但我不知道这一点。）， 但您可以使用以下link，在此帮助下，您可以检查所有应用程序的存在，并根据您的一些需求进行自定义。

此WONT提供已安装应用程序的列表，但您可以通过此代码获取在后台运行的应用程序列表及其相关进程。

魔术师的回答和Victor对头文件链接的评论帮助我解决了这个问题。
我确实想补充一点，你必须将MobileInstallation.framework添加到Xcode中的“Linked Frameworks and Libraries”。我在这里找到了这个框架：
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/System/Library/PrivateFrameworks
我可以确认这适用于非越狱设备。应用程序商店对我来说不是一个问题。
这是我使用的代码：
NSDictionary *options = [NSDictionary dictionaryWithObject:@"Any" forKey:@"ApplicationType"];
NSDictionary *apps = (__bridge NSDictionary *) MobileInstallationLookup((__bridge CFDictionaryRef) options);
