objective c - UIScrollView, how to set size to image size? -


I have UIScrollView, with UIImageView at the top, I have a few things that I'm trying to decide: < / P>

1) Initially, the image is scaled to fit the screen (this is good). How can I set a border so that you can zoom out of this point (I do not want to see anyone from the background)?

I could not find anything of some sort of maxSize property

2) How can I set that amount to someone who can zoom? I do not want users to do X8 or anything like that.

1) 

  [scrollwidth setminumzscale: float];   
 2)  
  [scrollview setmexiumzscake: float];

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 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. 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"...
