ios - How can i make clickable uiimage? -


i have 1 menubar uiimage. want make 5 menu on menubar clickable , link view. can tell me way can that? found people using uibutton on uiimage, fine me , how can separate menu bar 5 pieces.

thanks both rmaddy , brent royal-gordon

i decided use uiimage menubar background , add uibutton on it. try thing this:

nsurl *url = [nsurl fileurlwithpath:[[nsbundle mainbundle]                                      pathforresource:@"movie" oftype:@"mp4"]];  mpmovieplayercontroller *movieplayer = [[mpmovieplayercontroller alloc] initwithcontenturl:url];  [[nsnotificationcenter defaultcenter] addobserver:self                                          selector:@selector(movieplaybackdidfinish:)                                              name:mpmovieplayerplaybackdidfinishnotification                                            object:movieplayer];  movieplayer.controlstyle = mpmoviecontrolstylenone; movieplayer.repeatmode = mpmovierepeatmodeone; movieplayer.shouldautoplay = yes; movieplayer.scalingmode = mpmoviescalingmodefill; [movieplayer.view setframe:cgrectmake(0,0,1330,320)];  [scrollview setbackgroundcolor:[uicolor blackcolor]]; [scrollview setcontentsize:cgsizemake(1330,320)]; [scrollview setscrollenabled: yes]; [scrollview setshowshorizontalscrollindicator:no]; [scrollview setshowsverticalscrollindicator:no];  [scrollview addsubview:movieplayer.view]; [self.view addsubview:scrollview];  uiimageview *imageview = [[uiimageview alloc] initwithframe:image.frame];    uiimage *menubar = [uiimage imagenamed:@"bg.jpg"]; imageview = [[uiimageview alloc] initwithimage:menubar]; imageview.contentmode = uiviewcontentmodescaletofill; imageview.frame = cgrectmake(0, 258, imageview.frame.size.width, 25); [self.view addsubview:imageview];  [imageview setuserinteractionenabled:yes];  uibutton *btn = [uibutton buttonwithtype:uibuttontypecustom];    [btn setframe:cgrectmake(0,258,30,25)]; [btn addtarget:self action:@selector(buttonpress:) forcontrolevents:uicontroleventtouchupinside]; [btn settitle:@"home" forstate:uicontrolstatenormal];  [imageview addsubview:btn];

but button not visible on screen when run on simulator. did wrong?

using gesture recognizer bad idea because:

  1. it forces interpret touch areas each submenu yourself.
  2. it's opaque voiceover.
  3. it doesn't show highlight when user touches button. these sorts of highlights user understand user interface doing, they're valuable.

what should split single image 5 in graphics tool photoshop, , make each of these slices image of uibutton. you'll need design highlighted states these images (shown when 1 of them held down), should doing anyway.

if must slice image in code, can using uigraphicsbeginimagecontextwithoptions(size, no, 0.0) , drawing big image using drawatpoint: appropriate offset slice want, 99.99999% of time, it'll make more sense slice images once on big, beefy, wall-plug-powered mac every time app runs on tiny, slow, battery-powered ios device.
