            ret = [arrObj lastObject];
        }
          break;
        case 4: {
            // [iOS9 +) 
            ret = [arrObj objectAtIndex:2];
        }
          break;
        default:
            break;
    }
    return ret;
}

2.通過包名去打開應用

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

更新 來源()

在iOS 11 以前我們可以使用LSApplicationWorkspace來獲取手機上已安裝的應用列表

iOS 11 上獲取所有已安裝應用接口被禁，但可以根據BundleId檢查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，經筆者驗證，此方法在iOS9以上系統可正確運行。
