NSDateFormatter formatting

iOS下的日期时间字符串格式化.

Ever wonder just what you could put in NSDateFormatter format strings? Enough to actually go to the trouble of actually dumping specifiers and results? Nah, us neither. But somebody did, and here’s what they found:

a: AM/PM
A: 0~86399999 (Millisecond of Day)
 
c/cc: 1~7 (Day of Week)
ccc: Sun/Mon/Tue/Wed/Thu/Fri/Sat
cccc: Sunday/Monday/Tuesday/Wednesday/Thursday/Friday/Saturday
 
d: 1~31 (0 padded Day of Month)
D: 1~366 (0 padded Day of Year)

Permanently configuring LLDB not to stop on signals

In case anyone else ever has this question, I finally solved it by adding a breakpoint in NSApplicationMain() (for plain C programs, main() would of course work as well).

I set the breakpoint action to process handle SIGUSR2 -n true -p true -s false , and enabled the "Automatically continue after evaluating" option.

If anyone has a more elegant solution, I'd be happy to hear.
