Hello World example

Example of title slide generated by LibPptx 
#import "libpptx.framework/Headers/PptxManager.h"

@implementation SomeClass

-(void) generatePptx
{
   // point PptxManager to default.pptx (a template presentation)
   NSString *templateUrlAddress = [[NSBundle mainBundle] pathForResource:@"default" ofType:@"pptx"];

   // for trial mode keep license and email empty
   PptxManager* manager = [[PptxManager alloc] initWithLicense:@"" andEmail:@"" andTemplate:templateUrlAddress];

   // retrieve pointer to Presentation from PptxManager to manipulate presentation
   Presentation* presentation = [manager presentation];
     
   // add slide based on layout 
   Slide* slide1 = [presentation addSlideWithLayoutId:2];
        
   Title* title = [[slide1 createShapeOfType:[Title class]] withText:@"Hello world!"];
   [[[[title getContent] withBold:YES] withItalic:YES] withSizePt:72];
        
   [slide1 addShape: title];
   [slide1 addShape: [[slide1 createShapeOfType:[SubTitle class]] withText:@"LibPptx generated this"]];

   NSString* savedLocation = [manager saveWithFileName:@"my.pptx"];
   NSLog(@"Your presentation has been saved to: %@", savedLocation);
}
