Both of these contexts go to the persistent store (i.e., I'm not using parent/child contexts). For the view controller, I'm using a UITableViewController with a NSFetchedResultsController that uses the 1st UI managed object context. I am merging changes from the 2nd managed object context into the 1st context by observing the

This way I create a Pulse News look like application. My problem with this is that sometimes the 6th and 11th row disappears completely, leaving a blank space where it should be the cell. I wouldn't actually mind, if all the cells were like this (and this way I could assume that I wasn't doing things correctly), but the thing is, is just happening with those specific ones. My theory The 6th and 11th rows are the ones that appears when I

需求：在scrollview的子View不为0，当scrollview的展示的index不为0且向右滑动CollectionView。CollectionView不滑动Cell,而是让scrollview切换内容，想左滑同理。 开始真的难到我了。后来在CollectionView上添加了一个滑动手势，代替自带的滑动手势。 UIPanGestureRecognizer *ges = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(mainViewGes:)]; ges.delegate =self; [_mainView addGestureRecognizer:ges 　　MainView即UICollectionView - (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{ //用自定义的手势覆盖collectionView自带的手势 return YES; } 　　重新这个方法。 - (void)mainViewGes:(UIPanGestureRecognizer *)ges{ if (ges.state == UIGestureRecognizerStateChanged) { //

But, I want to convert a cell array including other cell arrays to a matrix: >> C={{1,1}; {2,2}; {3,3}}; >> cell2mat(C) Error using cell2mat (line 53) Cannot support cell arrays containing cell arrays or objects. So, desired output is: >> mycell2mat({{1,1}; {2,2}; {3,3}}) ans = 1 1 2 2 3 3 How to do this?
