objective c - How to create a action to a button in Cocoa programmatically? -


I am trying to create a button in Mac program in Maco, but I do not know how, Trying to: 

  NSRact frame = NSMKAct (10, 200, 80, 100); NSButton * btn = [[NSButton alloc] initWithFrame: frame]; [BTN Set button type: NsmemberRepash Inbutton]; [BTN set bezel style: NSRattbeizle style]; [BTN SETTITAL: @ "Click Me"]; [BTN Set Action: @Selector (hide labels :)); [Adsview view: BTN] See;   
 but line [BTN set action: @Selector (hide label)]; Do not work, how can I make an action here?  
 The method hides the labels in the function, because I used it with the second button.   
 
 
 Does your hidden label method take an argument? If not, leave it: Selector

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"...

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
