Crea .icns ad hoc

Non ha davvero senso inserire un'icona a bassa risoluzione nel formato icns ad alta risoluzione. Probabilmente dovrai modificare il ridimensionamento e creare immagini molto più grandi e quindi utilizzare uno strumento per assemblare il file.

Leggi in modo approfondito le linee guida di OS X e le linee guida iOS (che sono più complicate, ma una lettura più breve):

Ci sono un po 'di dettagli sulla confezione ad alta risoluzione - quindi probabilmente avrai bisogno di un paio d'ore o di giorni a seconda di quanto tempo hai fatto le risorse.

Oltre a consentire a Xcode di creare la risorsa icns e lo strumento da riga di comando iconutil , consulta tiff2icns

Oltre alla risposta di @bmike in precedenza, ecco un AppleScript che automatizza il processo di creazione .icns.

set export_folder to choose folder with prompt "Please select export folder."
set isImage to false
repeat while isImage = false
    set import_image to choose file with prompt "Please select image to covert."
    try
        tell application "Image Events"
            launch
            set test_image to open import_image
            if resolution of test_image = {} or resolution of test_image = {0, 0} then
                error ["Invalid Image"]
            end if
            set isImage to true
        end tell
    on error
        tell application "System Events"
            display dialog "Error: Selected file is invalid" with title "Error" with icon caution
        end tell
    end try
end repeat


try
    tell application "Finder"
        make new folder at export_folder with properties {name:"Icon.iconset"}
    end tell
on error
    tell application "System Events"
        display dialog "Error: Folder \"Icon.iconset\" already exists, will overwrite unless canceled" with title "Error" with icon caution
    end tell
end try

set export_folder_path to POSIX path of export_folder
set import_image_path to POSIX path of import_image
set icon_folder_path to POSIX path of export_folder_path & "/Icon.iconset"
