clock is clicking only by 1 minute interval, and the buttons are dead about calendarclock

when we press buttons, they respond eventually but with very long term.
And finally the app crashes.
I guess the algorithm of calculating edited calendars is causing this issue considering it happens on my iPad 2 and it becomes severe as long as the app is alive.

fixed! The actual problem was the app becomes slower and stops eventually. That was caused by subscribing selectedEvents in interval statements thus they were adding up every minutes.
