objective c - iOS, Keep track of uploading and downloading files in poped views -


i working on chat application on ios, has uploading/downloading requirement whatsapp upload/download, , i'm using somessage library.

but, if want upload image , popped view, upload cancelled, , managed upload/download in singleton class.

now, upload performed, cannot keep track of ui changes when enter view again.

any recommendation ??

thanks

in singleton can keep track of progress of transfers , when view entered again can open check see if there current transfer , show it's progress.

i have controller 1 of our apps handles uploading , downloading , keeps track of progress per item until queue finished. can clear queue upon completion or reference queue historical list of files sent/ received
