Objective-C & macOS PDF library integration

This guide will help you run Apryse samples and integrate a free trial of the Apryse SDK into Obj-C applications on macOS. Your free trial includes unlimited trial usage and support from solution engineers.


  • Xcode
  • Apryse's Objective-C PDF library for macOS:

Login/Sign Up to download the SDK

Initial setup

  1. Download the Apryse SDK.
  2. Extract the downloaded zip file and navigate to it.
  3. Get your Apryse trial key.

Run the samples

Run a specific sample

  1. Navigate to the OBJC folder in a sample project, for example /Samples/AddImageTest/OBJC and run the sample with

Run all samples

  1. Navigate to /Samples and run

The tests will run one by one.

Output files will be in /Samples/TestFiles/Output

Integrate into your application

This section will show you how to use our SDK to create a simple Apryse "Hello World!" application. It will create a document with one blank page and save it as a linearized PDF in its running directory.

  1. Navigate to the /Samples directory of the Apryse SDK and create a directory called myApp if it does not exist already. This guide will assume your project is named myApp.

  2. Enter your myApp directory and create a OBJC directory for organization. Then create a myApp.m file. Open this file in your favorite text editor and paste:

    #import <OBJC/PDFNetOBJC.h>
    #import <Foundation/Foundation.h>
    int main (int argc, const char * argv[])
        @autoreleasepool {
            int ret = 0;
            [PTPDFNet Initialize: 0];  // PDFNet must be initialized before accessing any Apryse API
            PTPDFDoc* doc = [[PTPDFDoc alloc] init];
            PTPDFRect * rect = [[PTPDFRect alloc] init];
            [rect Set: 0 y1: 0 x2: 612 y2: 792];
            PTPage* page = [doc PageCreate: rect];  // Start a new page
            [doc PagePushBack: page];   // Add the page to the document
            [doc SaveToFile: @"output.pdf" flags: e_ptlinearized];
            NSLog(@"Hello World!");
            return ret;
  3. In that same OBJC directory inside your myApp project folder add a makefile called Makefile and paste this inside:

    CFLAGS=-fobjc-exceptions -fobjc-arc
    LIBS=-L../../../Lib -lPDFNetC -framework Foundation
    $(TARGET): $(TARGET).m.o
        @echo "Linking target: $(TARGET)"
        $(CC) -o $@ $< $(LIBS) $(LDFLAGS)
    $(TARGET).m.o: $(TARGET).m
        @echo "Compiling target: $(TARGET)"
        $(CC) -c $< -o $@ $(CFLAGS) $(INCLUDES)
    all: $(TARGET)
        rm -fr $(TARGET) *.o
    rebuild: clean all
    .PHONY: all clean rebuild
  4. Run the project by executing:


    followed by:


    If all goes well, your terminal should output:

    PDFNet is running in demo mode.
    Permission: write
    Hello World!

Check the output.pdf that the program output in the same directory. It should be a PDF with one blank page.
