iOS中日期和字串的相互轉化

標籤：

例1、 從伺服器段擷取到的字串轉化為時間如：轉化1416882712000NSString *time =1416882712000；//伺服器上的時間字串NSInteger num = [time integerValue]/1000;（重點）NSDateFormatter *formatter = [[[NSDateFormatter alloc]init]autorelease];[formatter setDateStyle:NSDateFormatterMediumStyle];[formatter setTimeStyle:NSDateFormatterShortStyle];[formatter setDateFormat:@YYYY-MM-dd];NSDate*confromTimesp = [NSDate dateWithTimeIntervalSince1970:num];NSString*confromTimespStr = [formatter stringFromDate:confromTimesp];cell.DateContent.text = confromTimespStr;轉化之後結果為：2014-11-25例2、如何如何將一個字串如“ 20110826134106”裝化為任意的日期時間格式，下面列舉兩種類型：NSString*string = @20110826134106;NSDateFormatter *inputFormatter= [[[NSDateFormatter alloc] init] autorelease];[inputFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@en_US] autorelease]];[inputFormatter setDateFormat:@yyyyMMddHHmmss];NSDate*inputDate = [inputFormatter dateFromString:string];NSLog(@date= %@, inputDate);NSDateFormatter *outputFormatter= [[[NSDateFormatter alloc] init] autorelease];[outputFormatter setLocale:[NSLocale currentLocale]];[outputFormatter setDateFormat:@yyyy年MM月dd日 HH時mm分ss秒];NSString *str= [outputFormatter stringFromDate:inputDate];NSLog(@testDate:%@,str);兩次列印的結果為：date= 2011-08-26 05:41:06 +0000testDate:2011年08月26日 13時41分06秒
