iOS string splitting

    nsstring* postr = @ "Local-8009-1408082245-8.wav";        nsarray* poArr1 = [Naviaddressandport componentsseparatedbystring:@ "-"];    nsarray* POARR2 = [Postr componentsseparatedbycharactersinset:[nscharacterset charactersetwithcharactersinstring:@ " -."]];    NSLog (@ "%@,%@", POARR1,POARR2);

is generally the first method of splitting, but if you encounter data like the above, there is actually a problem

The POSTR's split format is the caller-called-start time-duration. wav

In the first way, the time-length field needs to be split again, and in the second split, it is done one at a time.

Of course the second is not without shortcomings, if the previous field contains., you can't do that.
