获取手机中安装的所有App

1.获取手机中安装的所有App
1.1.runtime中的方法，所以要导入
#include<objc/runtime.h>
1.2.在AppDelegate.m文件中的- (BOOL)application:(UIApplication
*)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中：
Class LSApplicationWorkspace_class =objc_getClass("LSApplicationWorkspace");
 NSObject* workspace = [LSApplicationWorkspace_classperformSelector:@selector(defaultWorkspace)];
 NSArray *allApplications = [workspaceperformSelector:@selector(allApplications)];//这样就能获取到手机中安装的所有App
打印出来是这样的：

2.判断手机中是否安装了某个App
这就需要对我们获取到的[b]allApplications做一下处理，这个数组中装的并不是常规的字符串，我们可以从打印结果看出，是一个LSApplicationProxy类型的，我们要把这个转换成字符串,而且我们可以从打印结果看出，这个字符串中不只包含了App的bundle
ID，还包含了安装的路径，因为这个路径不唯一不确定，我们判断是否安装了某个App只需判断这个字符串中的[/b][b]bundle ID，所有我们还要对字符串做处理。[/b]

NSInteger zlConnt =0;
for (NSString
*appStr in allApplications) {

       NSString
*app = [NSStringstringWithFormat:@"%@",appStr];//[b]转换成字符串[/b] 

       NSRange range = [apprangeOfString:@"org.ios.appprojuct.jqb”];//是否包含这个[b]bundle
ID[/b]
       

        if (range.length
> 1) {

           
            zlConnt ++;
        }
       

    }

   
   if (zlConnt >=
1) {
       

        NSLog(@"已安装金钱豹org.ios.appprojuct.jqb");

       

    }
