iOS Question RichText and images to Clipboard or File


Licensed User
I have some RichText and 2 graphs that I want to ultimately email to someone. What would be the best way of going about getting this data into an email? These are 3 possibilities I considered but not sure which one is best and how implement the best one.

1) Create an email and try and insert into the email via code?
2) Place it on the clipboard and later paste it into an email I create?
3) Write it to a file and later attach the file to the email?

Thanks for any and all suggestions....
