iphone - Loading a view into a UIScrollView AND getting the content inside to work -

i have tab based application working on.

i have view controller named detailsview.m, accompanying nib file called detailsview.xib. has couple of uilabels in, linked using iboutlet detailsview.m view controller. when load view controller/view using tab bar controller, works fine , uilabels populated dynamically.

now want load entire view inside uiscrollview instead can fit more content in.

so created view controller called detailsholder.m nib file called detailsholder.xib, , assigned tab bar controller.

i wrote code below load first view (detailsview) uiscrollview in second view (detailsholder). wrote in viewdidload method of detailsholder:

detailsview* detailsview = [[detailsview alloc] initwithnibname:@"detailsview" bundle: nil]; cgrect rect = detailsview.view.frame; cgsize size = rect.size; [scrollview addsubview: detailsview.view];     scrollview.contentsize = cgsizemake(320, size.height); 

this correctly loads sub view uiscrollview, however, labels inside detailsview no longer anything. when put nslog inside viewdidload of detailsview - never logs anything. it's if i've loaded nib ok, no longer associated view controller anymore. missing here? i'm bit of newbie in obj c/ios (but have many years actionscript/javascript knowledge.

thanks in advance,

rich

edit: contents of detailsview requested:

detailsview.h:

#import <uikit/uikit.h> #import "appmodel.h"  @interface detailsview : uiviewcontroller {     iboutlet uitextview* textview;     iboutlet uiimageview* imageview; }  @end 

detailsview.m

#import "detailsview.h"  @implementation detailsview  - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil {     self = [super initwithnibname:nibnameornil bundle:nibbundleornil];     if (self) {         // custom initialization     }     return self; }  - (void)dealloc {     [super dealloc]; }  - (void)didreceivememorywarning {     // releases view if doesn't have superview.     [super didreceivememorywarning];      // release cached data, images, etc aren't in use. }  #pragma mark - view lifecycle  - (void)viewdidload {     [super viewdidload];     // additional setup after loading view nib. }  - (void)viewwillappear:(bool)animated {     appmodel* model = [appmodel sharedinstance];      [model loaddata];      int selectedlocation = [model getselectedlocation];     nsarray *locations = [model getlocations];     nsarray *data = [locations objectatindex:selectedlocation];      textview.text = [data objectatindex: 0];       uiimage *theimage = [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:[data objectatindex: 4] oftype:@"jpg"]];      imageview.image = theimage;  }  - (void)viewdidunload {     [super viewdidunload];     // release retained subviews of main view.     // e.g. self.myoutlet = nil; }  - (bool)shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation {     // return yes supported orientations     return (interfaceorientation == uiinterfaceorientationportrait); }  @end 

essentially doing grabbing selectedlocation (int) singleton (which model), grabbing array model, , trying insert image , text view. in nib file, have uiimageview , uitextview, have linked 2 iboutlets declared in detailsview.h

when use view controller this, many events not occur in view controller, e.g. viewwillappear, viewwilldisappear , device rotation event. best guess did initialisation in of event methods. posting code detailsview make easier find problem.
