iOS 获取手机安装的所有的Apps

#import <objc/runtime.h>

- (void)installedApplications
{
    Class lsawsc = objc_getClass("LSApplicationWorkspace");
    NSObject* workspace = [lsawsc performSelector:NSSelectorFromString(@"defaultWorkspace")];
    NSArray *apps = [workspace performSelector:NSSelectorFromString(@"allInstalledApplications")];


    Class LSApplicationProxy_class = objc_getClass("LSApplicationProxy");
    for (int i = 0; i < apps.count; i++) {
        NSObject *temp = apps[i];
        if ([temp isKindOfClass:LSApplicationProxy_class]) {
            //应用的bundleId
            NSString *appBundleId = [temp performSelector:NSSelectorFromString(@"applicationIdentifier")];
            //应用的名称
            NSString *appName = [temp performSelector:NSSelectorFromString(@"localizedName")];
            //应用的类型是系统的应用还是第三方的应用
            NSString * type = [temp performSelector:NSSelectorFromString(@"applicationType")];
            //应用的版本
            NSString * shortVersionString = [temp performSelector:NSSelectorFromString(@"shortVersionString")];
        
            NSString * resourcesDirectoryURL = [temp performSelector:NSSelectorFromString(@"containerURL")];
        
            NSLog(@"类型=%@应用的BundleId=%@ ++++应用的名称=%@版本号=%@\n%@",type,appBundleId,appName,shortVersionString,resourcesDirectoryURL);
        
        }
    }  
}

//调用App  
- (void)openApp {
    PrivateApi_LSApplicationWorkspace* workspace = [NSClassFromString(@"LSApplicationWorkspace") new];      
    [workspace openApplicationWithBundleID:@"com.xxx.xxx"];  
}

//获取所有App包名
1.获取到手机里面所有的APP包名

- (void)touss
{
    Class lsawsc = objc_getClass("LSApplicationWorkspace");
    NSObject* workspace = [lsawsc performSelector:NSSelectorFromString(@"defaultWorkspace")];
    NSArray *Arr = [workspace performSelector:NSSelectorFromString(@"allInstalledApplications")];
    for (NSString * tmp in Arr)
    {
        NSString * bundleid = [self getParseBundleIdString:tmp];
        NSLog(@"%@",bundleid);
    }
}

- (NSString *)getParseBundleIdString:(NSString *)description
{
    NSString * ret = @"";
    NSString * target = [description description];
    // iOS8.0 "LSApplicationProxy: com.apple.videos",
    // iOS8.1 "<LSApplicationProxy: 0x898787998> com.apple.videos",
    // iOS9.0 "<LSApplicationProxy: 0x145efbb0> com.apple.PhotosViewService <file:///Applications/PhotosViewService.app>"
    if (target == nil) {
        return ret;
    }
    NSArray * arrObj = [target componentsSeparatedByString:@" "];
    switch ([arrObj count]) {
        case 2: // [iOS7.0 ~ iOS8.1)
        case 3: {
             // [iOS8.1 ~ iOS9.0)
            ret = [arrObj lastObject];
        }
          break;
        case 4: {
            // [iOS9 +) 
            ret = [arrObj objectAtIndex:2];
        }
          break;
        default:
            break;
    }
    return ret;
}

2.通过包名去打开应用

    Class lsawsc = objc_getClass("LSApplicationWorkspace");
    NSObject* workspace = [lsawsc performSelector:NSSelectorFromString(@"defaultWorkspace")];
    // iOS6 没有defaultWorkspace
    if ([workspace respondsToSelector:NSSelectorFromString(@"openApplicationWithBundleID:")])
    {
        [workspace performSelector:NSSelectorFromString(@"openApplicationWithBundleID:") withObject:@"com.Calendar.jbp"];
    }

更新 来源()

在iOS 11 以前我们可以使用LSApplicationWorkspace来获取手机上已安装的应用列表

iOS 11 上获取所有已安装应用接口被禁，但可以根据BundleId检查App是否存在

- (BOOL)isInstalled:(NSString *)bundleId {
    NSBundle *container = [NSBundle bundleWithPath:@"/System/Library/PrivateFrameworks/MobileContainerManager.framework"];
    if ([container load]) {
        Class appContainer = NSClassFromString(@"MCMAppContainer"); 
        #pragma clang diagnostic push
        #pragma clang diagnostic ignored "-Wundeclared-selector"
        id container = [appContainer performSelector:@selector(containerWithIdentifier:error:) withObject:bundleId withObject:nil]; 
        #pragma clang diagnostic pop NSLog(@"%@", [container performSelector:@selector(identifier)]); 
        if (container) { 
            return YES;
        } else { 
            return NO;
        }
    } 
    return NO;
}

此方法在iOS8中不起作用，经笔者验证，此方法在iOS9以上系统可正确运行。

慢慢来，一步一个巴掌印~~~
