Fixing layout glitch when UILabel width == 0.

If UILabel width == 0, then it stays that way after 65 line.
Then you create a frame in 85 line by extending 0 to full size, and in 92 line ignore it, subtracting `view.frame` instead of `frame`.
I don't find replacing `view.frame` to `frame` helpful with UILabel's, so I just added the change to 65 line, completely fixing a problem. 
Now I can add labels without ever touching there frame.
