iphone - setContentOffset on UIScrollView the right way -
i'm using code scroll uiscrollview down because i'm adding new uiview on bottom , want scroll down it. this: cgpoint newoffset = cgpointmake(mainscrollview.contentoffset.x, mainscrollview.contentoffset.y + floorf(bottomattachmentview.frame.size.height / bottomattachmentview.multfactor)); [mainscrollview setcontentoffset:newoffset animated:yes]; i add new element's height y of uiscrollview 's contentoffset scrolls out of scrollview contentsize , lower, possible scroll. happens because modify contentsize before calling method above , height of scroll view shrinks. how call setcontentoffset wouldn't make scrollview scroll out of it's own contentsize ? thanks! all had actually, scroll uiscrollview bottom this: cgpoint bottomoffset = cgpointmake(0, [mainscrollview contentsize].height - mainscrollview.frame.size.height); [mainscrollview setcontentoffset:bottomoffset animated:yes];
