libpq.framework for iOS 11

An XCode project to compile your own libpq.framework for iOS 11.x

libpq is a set of library functions that allow client programs to pass queries to the PostgreSQL backend database server and to receive the results of these sql queries.

This repository allows you to easily create a libpq.framework to use in your iOS applications.

Getting Started

libpq.framework has no external dependencies apart from libssl.a and libcrypto.a from OpenSSL, which we download and compile by using the build-libssl.sh script so that you can be sure you are downloading it from the official OpenSSL repository. So getting started is easy:

  • Install Git and the latest Xcode with the iOS 11.x SDK.

  • Make sure that xcode-select points to the correct location by running:

    sudo /usr/bin/xcode-select --switch /Applications/Xcode.app/Contents/Developer

  • Fork this repo from GitHub:

    git clone git://github.com/spacialdb/libpq.framwework.git

  • Run the script to download and compile OpenSSL:

    ./build-libssl.sh

  • Open libpq.xcodeproj with XCode and build the framework.

Download precompiled Framework

You can also download a precompiled libpq.framework from: libpq.framework.zip

Usage

Drop the framework into your project's Navigator and don't forget to copy it to your project, and you should be ready to go. See libpq's example programs for sample code. In general for Objective-C one would need to do something like:

#import <libpq/libpq-fe.h>

const char *_connectionString;
...
PGconn *_pgconn = PQconnectdb(_connectionString);
if (PQstatus(_pgconn) != CONNECTION_OK) {
    ...
}

PGresult *res = PQexec(_pgconn, "BEGIN");
if (PQresultStatus(res) != PGRES_TUPLES_OK) {
    ...
}
PQclear(res);
...

PQfinish(_pgconn);
