Add support for multiple images and emojis

[Liampronan]

I'm working on a fork that adds three new types: .images, .emoji, and .emojis. If there's any interest, I can open a PR -- let me know if so!

In the spirit of the this repo's demos, here's a (albeit low-quality) gif :

yes please!

@Liampronan Did you ever make the emoji version?

[Liampronan]

I did but haven't submitted a PR -- is this library still maintained?

[jaymutzafi]

I don't know. But if you have a version I would love a peak at it. Actually all I'm trying to do is use a custom image but without having the color overlay on it and it also happens that the image I am using was taken from the bacon emoji so i wanted to see if your version helps me here.

@jaymutzafi basic implementation:

import SAConfettiView
import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        let confettiView = SAConfettiView(frame: self.view.bounds)
        confettiView.type = .Image("🥓".image())
        confettiView.colors = [UIColor.white]
        confettiView.startConfetti()
        view.addSubview(confettiView)
    }
}


extension String {
    func image() -> UIImage {
        let size = CGSize(width: 30, height: 35)
        UIGraphicsBeginImageContextWithOptions(size, false, 0);
        UIColor.clear.set()
        let rect = CGRect(origin: CGPoint.zero, size: size)
        UIRectFill(CGRect(origin: CGPoint.zero, size: size))
        (self as NSString).draw(in: rect, withAttributes: [NSFontAttributeName: UIFont.systemFont(ofSize: 30)])
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image!
    }
    
}

Splendid! Thank you.

👍 for images in general, you may need to ensure you call confettiView.colors = [UIColor.white] before startConfetti() -- it looks like setting colors doesn't reset the confettiView colors if it's already animating. haven't tested that out recently w/ non-emoji images but I'd imagine similar funcitonality

[jaymutzafi]

Yeah .white solved my color problem, so I'm all good! But out of curiosity I've tried "🥓".image() and it says string has no member .image()

[Liampronan]

did you add teh extension from the above code snippet? it adds .image() to String

[jaymutzafi]

Ah silly me, I messed it up. Looks good. (that's pretty clever btw, nicely done)
