iOS 获取手机上安装的app

前段时间，因为项目需求，需要知道目前手机上都安装了哪些app(非系统自带)，因此在网上找了找，发现苹果提供的私有api 是具有此功能的。代码如下：
- (NSArray *)getAllAppsFromDevice
{
//获取手机上所有的app
Class LSApplicationWorkspace_class = objc_getClass("LSApplicationWorkspace");
NSObject *workspace = [LSApplicationWorkspace_class performSelector:@selector(defaultWorkspace)];
NSArray *apps = [workspace performSelector:@selector(allInstalledApplications)];
Class LSApplicationProxy_class = objc_getClass("LSApplicationProxy");
NSMutableArray *deviceApps = [NSMutableArray new];
for (int i = 0; i < apps.count; i++) {
NSObject *temp = apps[i];
if ([temp isKindOfClass:LSApplicationProxy_class]) {
ApplicationModel *appModel = [[ApplicationModel alloc] init];
NSString *tempKey = [temp performSelector:NSSelectorFromString(@"applicationIdentifier")];
if ([tempKey containsOtherString:@"apple"]) {
continue;
}
//版本
NSString *tempVersionNumber = [temp performSelector:NSSelectorFromString(@"shortVersionString")];
appModel.appNumber = tempVersionNumber;

     //bundle id
     NSString *tempAppkey = [temp performSelector:NSSelectorFromString(@"applicationIdentifier")];
     appModel.appKey = tempAppkey;
     [deviceApps addObject:appModel];
      }
   }
   return [deviceApps copy];
}
