iOS 获取是否安装了某个App

*必要条件:需要知道这个App的bundleId

- (BOOL)isHadCompleteWithBundleId:(NSString *)bundleId {
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 11.0) {
        NSBundle *container = [NSBundle bundleWithPath:@"/System/Library/PrivateFrameworks/MobileContainerManager.framework"];
        if ([container load]) {
            Class appContainer = NSClassFromString(@"MCMAppContainer");
            
            id test = [appContainer performSelector:@selector(containerWithIdentifier:error:) withObject:_listModel.bundleId withObject:nil];
            NSLog(@"%@",test);
            if (test) {
                return YES;
            } else {
                return NO;
            }
        }
        return NO;
        
    }else{
        //低于iOS 11
//方法的实现见下面
        NSArray *arr = [[XBInfoConfiger shareInfo] touss];
        if ([arr containsObject:_listModel.bundleId]) {
            return YES;
        }else{
            return NO;
        }
    }
}

//1.获取到手机里面所有的APP包名

- (NSArray*)touss
{
    Class lsawsc = objc_getClass("LSApplicationWorkspace");
    NSObject* workspace = [lsawsc performSelector:NSSelectorFromString(@"defaultWorkspace")];
    NSArray *Arr = [workspace performSelector:NSSelectorFromString(@"allInstalledApplications")];
    NSArray *arr = [workspace performSelector:NSSelectorFromString(@"allApplications")];
    NSMutableArray *tempArr = [NSMutableArray array];
    for (NSString * tmp in Arr)
    {
        NSString * bundleid = [self getParseBundleIdString:tmp];
        if (bundleid.length > 0) {
            [tempArr addObject:bundleid];
        }
//        NSLog(@"-----%@------",bundleid);
    }
    return [tempArr copy];
}

- (NSString *)getParseBundleIdString:(NSString *)description
{
    NSString * ret = @"";
    NSString * target = [description description];
    
  
    
    if (target == nil)
    {
        return ret;
    }
    NSArray * arrObj = [target componentsSeparatedByString:@" "];
    if (SYS_Version >= 9.0) {
        ret = [arrObj objectAtIndex:2];
    }else{
        ret = [arrObj lastObject];
    }
    
    return ret;
