一段落

とりあえずtiling routineは完成。ウィンドウの横幅固定で並べてた時には起こらなかった問題ができるだけオリジナルに近い横幅を保持するように変更した途端に溢れてきてそれを一個一個潰した。要はcurrentな画像とpreviousな画像の横幅を小さい方に揃える際に、previousを縮小する場合に考慮すべき値が漏れ続けてた。特殊相対性理論を一般相対性理論に昇華させる苦労がちょっとだけ（百億分の1くらい）わかった気がする。

できた。これであらゆるケースに対応できるはず。

と思ってたらlink,audioでボタンを押すとpostのUIViewControllerがdeallocされてることに気付いた。UIViewの時はいけてた（はず）のに。strongで宣言してviewをNSMutableArrayに入れといても次のpostを同じivarでallocしたらpreviousなpostのivarはdeallocされる。viewが生きてるから気づかんかったけど、まあ当然っちゃ当然の振る舞いなんだろう。無理やりcopyしたりするのもややこしいしメモリも気になるのでボタンをrootのvcからpostのviewに貼ってイベントの受取をrootのvcになるよう変更した。

tManCtrlr.m
- (void)mkSinglePostView{
 for(int i=[pvArr count];i<[contArr count];i++){
  postv=[[SinglePost2 alloc]init];
  [postv constructWithtype:[typeArr objectAtIndex:i] cont:[contArr objectAtIndex:i] bnamet:[bnameArr objectAtIndex:i]];
  [naxArr addObject:postv.nax];
  if(postv.open){
   [openArr insertObject:[postv.open objectAtIndex:1] atIndex:i];
   UIImage *opimg,*opimg_on;
   if([[postv.open objectAtIndex:0]isEqual:@"link"]){
    opimg=[UIImage imageNamed:@"openlink"];opimg_on=[UIImage imageNamed:@"openlink_on"];
   }
   else if([[postv.open objectAtIndex:0]isEqual:@"audio"]){
    opimg=[UIImage imageNamed:@"listen"];opimg_on=[UIImage imageNamed:@"listen_on"];    
   }
   UIButton *open=[UIButton buttonWithType:UIButtonTypeCustom];//move.alpha=0.7;
   [open setImage:opimg forState:UIControlStateNormal];[open setImage:opimg_on forState:UIControlStateHighlighted];
   [open setFrame:CGRectMake(ofv(postv.open,2),ofv(postv.open,3),opimg.size.width,opimg.size.height)];
   [open addTarget:self action:@selector(openPage) forControlEvents:UIControlEventTouchUpInside];
   [postv.view addSubview:open];
  }
  [postv.view setTag:i+1];
  [pvArr addObject:postv.view];
 }
 [pvlayer.view addSubview:[pvArr objectAtIndex:now-1]];[pvlayer.view setFrame:self.view.bounds];
 if(!now_all) now_all=[[UILabel alloc]init];[self na];
 if(!caption) caption=[[UILabel alloc]init];[self mkCaption];
}

できた。とりあえず顕在しているエラーは潰せたはず。
次は全typeの回転対応とiPad対応してreblog,like処理やってsetting対応してtimelineか。長い。
