ios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

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 = com.apple.mobilesms.notification
2016-06-01 11:11:41.541 jqb[7537:2410265] app = com.apple.mobilesms.compose
2016-06-01 11:11:41.541 jqb[7537:2410265] app = com.apple.Fitness

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 = [ NSString stringWithFormat:@"%@",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" );
       
    }
