@InjayTseng does it crash on simulator? which IOS and which device?

[InjayTseng]

Thank you for reply.
on both device (iPhone 6/ iOS8.1) and all simulators.

Am i missing something?

[mythodeia]

@InjayTseng change both instances of:
@property (assign, nonatomic) NSDate *time;

to this
@property (nonatomic, readwrite) NSDate *time;
in SPClockView.m

[InjayTseng]

Perfect, works for me!
Thanks a lot !!
