I hope I understand correctly. Without simply typing out the actual code you need, this is how I would approach it:<\/p>\n<p>I would create an array with dictionaries containing the letter as key and the point as value, looking something like this:<\/p>\n<pre><code>[\n[\"A\": CGPoint(x: 0, y: 0)],\n[\"B\": CGPoint(x: 0, y: 0)],\n[\"C\": CGPoint(x: 0, y: 0)],\n[\"D\": CGPoint(x: 0, y: 0)],\n[\"E\": CGPoint(x: 0, y: 0)],\n[\"F\": CGPoint(x: 0, y: 0)],\n]\n<\/code><\/pre>\n<p>(or nicer, this array could have custom models containing similar info)<\/p>\n<p>Then, use this array to plot the UIButtons on the view, giving each UIButton a reference to the item in the array by subclassing it, e.g the key of the dictionary.<\/p>\n<pre><code>CustomButton: UIButton { \n    var key: String?\n}\n<\/code><\/pre>\n<p>Then when tapping the first button, store that key in a local variable named <code>start<\/code> and when tapping the second button store that key in a local variable named <code>end<\/code>. Subsequently, loop through the array and find the matching <code>start<\/code> key and use the values in the array to draw the lines until you find the matching <code>end<\/code> key.<\/p>\n<p>Since I was in the mood, I created a simple playground demo, but this is usually not the way it works. You don&#8217;t just ask for sample code, you ask for  help to solve a problem.<\/p>\n<p>Anyway, you can find the demo here: <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/gist.github.com\/pvroosendaal\/f1617fe7e164bc94f0d37d3175252e2f\">https:\/\/gist.github.com\/pvroosendaal\/f1617fe7e164bc94f0d37d3175252e2f<\/a><\/p>\n<p>By the way, this is by far the crappiest piece of code I wrote, but it does what you want.<\/p>\n<p>I hope it makes sense, otherwise, please let me know.<\/p>\n<\/p><\/div>\n<div class=\"mt24\"><\/div>\n<\/div>\n<p>            <span class=\"d-none\" itemprop=\"commentCount\">2<\/span> <\/p><\/div>\n<\/div>\n<p>[ad_2]<\/p>\n<p>solved How to draw dynamic line path on imageView? <\/p>\n","protected":false},"excerpt":{"rendered":"<p>[ad_1] First of all I must say your question was not very clear, it took me a while to figure out what you actually want to achieve.
