Configuring the ContextĪs a next step, we are going to implement a function that takes a cocktail, extracts all the relevant information, and using the previous extensions, adds it to the context.Create a PDF Library app in iOS with Swift After doing so, we use the function 4 ( checkContext()) that will check if our text is exceeding the bounds of the page, and if so, start a new page dynamically and reset the cursor.įinally, the function 5 calculates the height of a multi-line sentence, so that we know where the text ends and where to start the next paragraph. We then use the indent and Page Size parameters to place our string in a CGRect described by the function definition (centered, single line left aligned, and multi-line left aligned). In the implementation of functions 1, 2 and 3, attributes are assigned to our text in an Attributed String variable.

These methods are added as an extension to UIGraphicsPDFRendererContext, which is the context that is going to render our PDF.Īll we have to do is dictate to the context everything we need our PDF to have (PDF metadata, PDF dimensions, page breaks, and of course the text we are going to present on the document).
