The first one mutates the existing NSMutable String.Adds to the end of the receiver the characters of a given string.
Maybe I'm making this harder than it needs to be, either that, or I'm just not grasping the real problem. When scrolling down or up in the list and pulling beyond the normal boundaries, the tableview data seems to overwrite the display for the row either above or below the current line. Not sure if this animated Gif will show up in Stack.
Here's an example: Recommend：objective c - i OS - Add a cell to empty UITable View Section w/ Core Data and NSFetched Results Controller style) in my app.
when I let go and it springs back, the score on the view is updated. – bbarnhart Dec 9 '14 at | show more comments Recommend：nsfetchedresultscontrolle - Core Data NSFetched Result Controller not updating on object changemy table and check the value of "deleted", it is actually set to YES.
– Drew Dec 5 '14 at When you added dynamically reflect any changes. :-) – Drew Dec 5 '14 at reload Data will reload all the data. That example with the delegate methods is what you want.
But geometry shaders are not extensively supported yet, even...

The object is getting released and deallocated because nothing is holding a strong reference...
The Table View has 3 sections, each with a view For Header In Section and a view For Footer In Section.
The user will be entering items that will be put in each section.
That means, to get the behavior you are looking for, the ball would need to approach exactly from one line mid-point to the next without any loss of energy. ios,unity3d,shader,mesh,particle You can do it using geometry shaders to create billboarding geometry from each vertex on the GPU.
