ios - UITabBar custom background image applied in one view controller instead of in the AppDelegate -


i working themes in iphone app. have 2 tabs in tab bar (timeline , settings) , when user goes second tab (settings), selects themes in settings , selects theme, styles background image , navigation bar of first table view controller in first tab (timeline). works.

i want achieve same thing tab bar, tab bar changes along background image , navigation bar.

in timeline table view, put following code in viewwillappear:

uiimage *tabbackgroundimage = [uiimage imagenamed:@"purplepinktopp.png"]; [[uitabbar appearance] setbackgroundimage:tabbackgroundimage];

however, tab bar never changes. way change tab bar in appdelegate changes everywhere. need allow user select theme , changes accordingly , need change on per view controller basis, same way navigation bar.

in viewwillappear of timeline table view, set navigation bar with:

uiimage *navbackgroundimage = [uiimage imagenamed:@"purplepinknav.png"]; [[uinavigationbar appearance] setbackgroundimage:navbackgroundimage forbarmetrics:uibarmetricsdefault];

that works. doesn't work tab bar code above.

edit: i've added apperancewhencontainedin viewwillappear:

uiimage *tabbackgroundimage = [uiimage imagenamed:@"solidpurple.png"]; [[uitabbar appearance] setbackgroundimage:tabbackgroundimage];  [uitabbar appearancewhencontainedin:[uitabbar class], [uitabbar class], nil];

but doesn't seem doing anything.

how can go fixing this? assistance immensely appreciated.

there refinement uiappearance proxy call try...

+ (id)appearancewhencontainedin:(class <uiappearancecontainer>)containerclass,...

this sets appearance uiappearance proxy compliant object supplied values when it's contained in specific view controller subclass.

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)...
