objective c - How can I see that a real world time has passed from a stored start date in obj-c/ios? -


The players of my game will be able to plant a tree, which will take 3 hours to grow. When the player logs back, how will I calculate that the tree is now fully developed? The date of the composition of the tree (planted) will be stored on one server, and I will have 3 hours in a second (make sure that it should be the end of NSN) also on the server.

Thanks for any help.

NSDate , and Use : 

  NSDate * now = [NSDate date]; Nteininternewallseasjobsplitting = [now timerivalzentet: plantingdate]; If (secondsplugging & gt; secondssprephirettoolyulgro) {...}

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part.

Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
