通过Bundle ID 唤醒App

1:查看手机中安装的所有App的包名

  • (void)GetPackageName{
    Class lsawsc = NSClassFromString(@"LSApplicationWorkspace");
    NSObject* workspace = [lsawsc performSelector:NSSelectorFromString(@"defaultWorkspace")];
    NSArray *Arr = [workspace performSelector:NSSelectorFromString(@"allInstalledApplications")];
    for (NSString * tmp in Arr)
    {
    NSString * bundleid = [self getParseBundleIdString:tmp];
    NSLog(@"%@",bundleid);
    }

}

  • (NSString *)getParseBundleIdString:(NSString *)description
    {
    NSString * ret = @"";
    NSString * target = [description description];

    // iOS8.0 "LSApplicationProxy: com.apple.videos",
    // iOS8.1 "<LSApplicationProxy: 0x898787998> com.apple.videos",
    // iOS9.0 "<LSApplicationProxy: 0x145efbb0> com.apple.PhotosViewService <file:///Applications/PhotosViewService.app>"

    if (target == nil)
    {
    return ret;
    }
    NSArray * arrObj = [target componentsSeparatedByString:@" "];
    switch ([arrObj count])
    {
    case 2: // [iOS7.0 ~ iOS8.1)
    case 3: // [iOS8.1 ~ iOS9.0)
    {
    ret = [arrObj lastObject];
    }
    break;

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

    }
    return ret;
    }

2:通过准确的包名唤起App

  • (void)OpenApp{

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

    }

}
