ios - Scrollview will not scroll even with larger contentsize -

got strange problem dont understand.

i set content size cgsize created called newsize. adding buttons in row in uiscrollview goes outside of frame of scrollview , changing content size match new width + 400 insurance.

    newsize.width = contentsizewidth+400;      nslog(@"newsize width: %f", newsize.width);      [_scrollviewoutlet addsubview:button];      [_scrollviewoutlet setcontentsize:newsize];      nslog(@"scrollviewoutlet content width: %f", _scrollviewoutlet.contentsize.width); 

the nslog prints out 768. scrolling enabled in scrollview in interface builder cannot scroll scrollview? problem be?

this may help: add buttons before provide contentsize.

// add buttons // create contentsizewidth presumably adding buttons height contentsizewidth = contentsizewidth + buttonheight;// repeat every button    [_scrollviewoutlet addsubview:button];  // create newsize newsize.width = contentsizewidth+400;  // set content size   [_scrollviewoutlet setcontentsize:newsize];
