判断手机中是否安装了某个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_class performSelector:@selector(defaultWorkspace)];

 NSArray *allApplications = [workspace performSelector:@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：

2016-06-01 11:11:41.540 jqb[7537:2410265] app = <LSApplicationProxy: 0x1566a3c50> com.apple.mobilesms.notification <file:///Applications/MessagesNotificationViewService.app>

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bundle ID，所有我们还要对字符串做处理。

 

NSInteger zlConnt = 0;

for (NSString *appStr in allApplications) {

 

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

 

 

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

       
        if (range.length > 1) {
           

            zlConnt ++;

        }

       
    }
   

    if (zlConnt >= 1) {

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