判斷手機中是否安裝了某個App

1.獲取手機中安裝的全部App

1.1.runtime中的方法，因此要導入

#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)]; //這樣就能獲取到手機中安裝的全部App

打印出來是這樣的：

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

2.判斷手機中是否安裝了某個App

這就須要對咱們獲取到的allApplications作一下處理，這個數組中裝的並非常規的字符串，咱們能夠從打印結果看出，是一個LSApplicationProxy類型的，咱們要把這個轉換成字符串,並且咱們能夠從打印結果看出，這個字符串中不僅包含了App的bundle ID，還包含了安裝的路徑，由於這個路徑不惟一不肯定，咱們判斷是否安裝了某個App只需判斷這個字符串中的bundle ID，全部咱們還要對字符串作處理。

 

NSInteger zlConnt = 0;

for (NSString *appStr in allApplications) {

 

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

 

 

        NSRange range = [app rangeOfString:@"org.ios.appprojuct.jqb」];//是否包含這個 bundle ID

       
        if (range.length > 1) {
           

            zlConnt ++;

        }

       
    }
   

    if (zlConnt >= 1) {

                NSLog(@"已安裝金錢豹org.ios.appprojuct.jqb");             }
