Wednesday of 06:06am performing tasks.3. Dailytimeintervaltrigger will be within a given time interval every N (1, 2, 3 ...) Seconds or hours to perform the task. For example: set to run from Monday to Friday 10:10 ~ 18:00 every 60 minutes. Although Simpletrigger can achieve similar tasks, Dailytimeintervaltrigger is not subject to the misfired tasks mentioned above.4.CalendarIntervalTrigger is typically used to process recurring interval tasks based on calendar time. You can handle tasks that

In Swift we have a powerful high-level logic abstraction, while low-level operations are deliberately limited. But in some cases we still want to do some hack work in C, and the cat will take a look at how to do it.Hacking is happy!!! ;]As the title says, now I have an int variable x, I want to get its address, then convert it to char type address, and then change the address of the content +1, if the C language to represent is:121,*pi = xchar *pc = (char *)pi1There are 2 questions to be written

I. If you use only global or static variables or do not use external variables, the code for block blocks is stored in the global zone;Two. If an external variable is used, the code for block blocks in arc is stored in the heap area;In the MRC, Block fast code is stored in the stack area;Three. block by default, external variables cannot be modified, only external variables can be read:In arc, an external variable exists in the heap, which is the same as the address outside block blocks in block
