iOS development nsdateformatter,nsdate and NSString date conversion, nsstring any format

Generally written in java+oracle background, may give you back the time style is this:

2014-01-20 13:24:33

Look at this time string is more complex, but the iOS SDK has been packaged for us to convert NSString to any nsdate or nsstring

Using the NSDateFormatter implementation

+ (NSString *) timefromstring: (NSString *) timestring{    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];< C1/>[formatter setdateformat:@ "Yyyy-mm-dd HH:mm:ss"];//Enter date format    nsdate *date = [Formatter datefromstring: timestring];//from NSString get a nsdate    nsdateformatter *formatter2 = [[NSDateFormatter alloc] init];    [Formatter2 setdateformat:@ "Yyyy/mm/dd"];           Output Date format    nsstring *str = [NSString stringwithformat:@ "%@",                     [Formatter2 stringfromdate:date]];// Convert from NSDate to nsstring        return str;}

in this way, you can convert any received background time string to the type of string you want!

Special attention:

HH rep, 24-hour system

HH stands for 12-hour (if 24-hour time, when converted to HH, a null value is generated)
