Golf Course Position Marker -- 2

Golf Course Position Marker I need an iOS app that will show the current GPS position in decimal format and have multiple buttons and when pressed will store the current position in a file that depending on which button is pressed will define the position. Buttons will be as follows: Hole Number – This should be a pull down allowing holes 1 thru 18 to be selected Tee box Left Rear Tee Box Right Rear Tee Box Left Front Tee Box Right Front Green Front Green Middle Green Rear Reset current hole Reset all holes If trying to set the position for one of the above and it already exists the user should be prompted if they wish to replace the existing position. Once a button is pressed I would like to have the respective button change colors and if there is enough screen space show the GPS position in decimal format near the button in question. This will be repeated for all 18 holes and will ultimately send the file that was written via email. Meaning it should launch an email message with the file attached which should be in a CSV format. The columns are in the attached
