Installing

Cocoapods (Coming Soon)

pod 'BTCDonationViewController'

Using

BTCDonationViewController is very simple to work with, you only need to make one call to get your View Controller, and then you can push to the navigation stack or display however you want. Just make sure you #import <BTCDonationViewController.h> in the class you want to use this in.

BTCDonationViewController *btcVC = [BTCDonationViewController newControllerWithBTCAddress:@"1LvoCg2axTrjgmGN6qT9kKXTA1M3ckBKJL" options:nil];

That's it. This gives you the stock BTCDonationViewController.

Customizing

However, you may want to customize even further. This leaves us with the options parameter of the mian method. BTCDonationViewController can consume an NSDictionary for the options parameter, which can manipulate the entire UI of the controller. Check out the following graphic for all of the keys necessary.

Keys

• kBTCDonationUIKeyBackgroundColor - UIColor
• kBTCDonationUIKeyHeaderTopTextColor - UIColor
• kBTCDonationUIKeyHeaderTopTextFont - UIFont
• kBTCDonationUIKeyHeaderTopTextString - NSString
• kBTCDonationUIKeyHeaderBottomTextColor - UIColor
• kBTCDonationUIKeyHeaderBottomTextFont - UIFont
• kBTCDonationUIKeyHeaderBottomTextString - NSString
• kBTCDonationUIKeyFooterTextColor - UIColor
• kBTCDonationUIKeyFooterTextFont - UIFont
• kBTCDonationUIKeyFooterTextString - NSString
• kBTCDonationUIKeyAddressLinkColor - UIColor
• kBTCDonationUIKeyAddressLinkFont - UIFont
• kBTCDonationUIKeyQRColor - UIColor

What this looks like

NSDictionary *uiOptions = @{kBTCDonationUIKeyBackgroundColor:[UIColor emeraldColor],
                            kBTCDonationUIKeyQRColor:[UIColor whiteColor],
                            kBTCDonationUIKeyHeaderTopTextColor:[UIColor whiteColor],
                            kBTCDonationUIKeyHeaderTopTextFont:[UIFont fontWithName:@"Futura" size:36.0f],
                            kBTCDonationUIKeyHeaderBottomTextColor:[UIColor whiteColor],
                            kBTCDonationUIKeyHeaderBottomTextFont:[UIFont fontWithName:@"Futura" size:18.0f],
                            kBTCDonationUIKeyFooterTextColor:[UIColor whiteColor],
                            kBTCDonationUIKeyFooterTextFont:[UIFont fontWithName:@"Futura" size:18.0f],
                            kBTCDonationUIKeyAddressLinkColor:[UIColor whiteColor],
                            kBTCDonationUIKeyAddressLinkFont:[UIFont fontWithName:@"Futura" size:14.0f]};
BTCDonationViewController *vc = [BTCDonationViewController newControllerWithBTCAddress:kDeveloperBTCAddress options:uiOptions];

Going even further

To customize this even further, you can add properties and manipulate the included .xibfile to customize to your heart's delight.

What's Left

Bugs

0.1.0

I've noticed that it's a little slow on a device, so there may be some ways to make this even faster. My guess is that the root of the problem is in one of the BGUtilities UIImage category methods necessary for creating the QR code, and manipulating the pixel colors. I'm wondering if the best option is to keep a placeholder image for the QR code while it loads from a background thread to keep app responsiveness as snappy as possible.

iPad

There is no native iPad support, so an iPad ViewController version of this should be available in the future too.

Demo

There is a demo project included in this repo. To run it, make sure you have Cocoapods installed on your machine. Navigate to the directory of the demo project, and run this line in your Terminal:

pod install

This will set up your project with Cocoapods, install the prerequisites, and then create a .xcworkspace file that you will use to build and run the demo.
