从 Xcode 项目中删除空行

Question

I have a very long Xcode project it has many empty lines which make vey difficult for me to navigate through the project.Is there any short key to remove empty lines from selected code?

 [inboxmessagesarray removeAllObjects];
    [checkimageArray removeAllObjects];


    NSMutableDictionary *callDict =[[NSMutableDictionary alloc] init];


    [callDict setObject:@"messages-getModuleMessages" forKey:@"call"];
    [callDict setObject:FB_API_KEY forKey:@"accessSecret"];
    NSString *x=[FBUserManager sharedUserManager].authToken;
    [callDict setObject:x forKey:@"authToken"];
    [callDict setObject:@"json" forKey:@"format"];

    [callDict setObject:@"archived" forKey:@"callType"];


    FBGenericWebHandler *handler = [[FBGenericWebHandler alloc] init];
    handler.delegate = self;
    [handler ArchivesMessages:callDict];
    handler = nil;
   [SVProgressHUD showWithStatus:@"Loading"];

Answer 2

Use regular expressions

Replace: ^\s*$ With: (leave blank/nil)

And the current file will have all blank lines removed.
