iphone - Where to build custom UITableViewCell: in layoutSubviews or initWithStyle:reuseIdentifier? -


as understand, there seem 3 ways of laying out custom table view cell:

  1. in interface builder.
  2. in layoutsubviews.
  3. in initwithstyle:reuseidentifier:.

what's difference between second , third methods? also, why not drawrect?

p.s. i'm following chapter 9 of book pro ios table views tim duckett, we're building custom uitableviewcells. author shows how lay out cell in same order above, don't know whats difference between last 2 since both away ib. noticed, though, author sets frames in layoutsubviews unlike in initwithstyle:reuseidentifier: properties concerning of view set (e.g., background image, background color, etc.).

you should create cell subviews in 

- initwithstyle: (uitableviewcellstyle) style reuseidentifier: (nsstring*) resueidentifier

and layout them in layoutsubviews. -initwithstyle:reuseidentifier method called once @ initialization, cell may have incorrect frame @ moment.

thats why need layout in layoutsubviews method, it's called when cell needs update layout, example, when autorotation occurs. if layout subviews in method, have valid cell's frame , correct subviews layout.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
