there 2 ways it----

- (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }  #pragma mark - collection view -(nsinteger)numberofsectionsincollectionview:(uicollectionview *)collectionview {     return 1; } -(nsinteger)collectionview:(uicollectionview *)collectionview numberofitemsinsection:(nsinteger)section {     return 30; }  -(uicollectionviewcell *)collectionview:(uicollectionview *)collectionview cellforitematindexpath:(nsindexpath *)indexpath {     magazinecell *mcell = (magazinecell *)[collectionview dequeuereusablecellwithreuseidentifier:cellid forindexpath:indexpath];      mcell.backgroundcolor = [uicolor lightgraycolor];      return mcell; }  #pragma mark collection view layout things // layout: set cell size - (cgsize)collectionview:(uicollectionview *)collectionview layout:(uicollectionviewlayout*)collectionviewlayout sizeforitematindexpath:(nsindexpath *)indexpath {      nslog(@"setting size item @ index %d", indexpath.row);     cgsize melementsize = cgsizemake(104, 104);     return melementsize; } - (cgfloat)collectionview:(uicollectionview *)collectionview layout:(uicollectionviewlayout*)collectionviewlayout minimuminteritemspacingforsectionatindex:(nsinteger)section {     return 0.0; }  - (cgfloat)collectionview:(uicollectionview *)collectionview layout:(uicollectionviewlayout*)collectionviewlayout minimumlinespacingforsectionatindex:(nsinteger)section {     return 2.0; }  // layout: set edges - (uiedgeinsets)collectionview: (uicollectionview *)collectionview layout:(uicollectionviewlayout*)collectionviewlayout insetforsectionatindex:(nsinteger)section {    // return uiedgeinsetsmake(0,8,0,8);  // top, left, bottom, right     return uiedgeinsetsmake(0,0,0,0);  // top, left, bottom, right }  @end 

and other way--------> 1.override standard flow layout. 2.add implementation that:

- (nsarray *) layoutattributesforelementsinrect:(cgrect)rect {     nsarray *answer = [super layoutattributesforelementsinrect:rect];      for(int = 1; < [answer count]; ++i) {         uicollectionviewlayoutattributes *currentlayoutattributes = answer[i];         uicollectionviewlayoutattributes *prevlayoutattributes = answer[i - 1];         nsinteger maximumspacing = 0;         nsinteger origin = cgrectgetmaxx(prevlayoutattributes.frame);          if(origin + maximumspacing + currentlayoutattributes.frame.size.width < self.collectionviewcontentsize.width) {             cgrect frame = currentlayoutattributes.frame;             frame.origin.x = origin + maximumspacing;             currentlayoutattributes.frame = frame;         }     }     return answer; }
