#NSDate #NSString #转化

后台的数据是这样的

historyVideos (

        {

        "MY_player_event_time" = "2015-11-30 22:55:17 +0000";

    },

乍一看还以为用NSDate *date 接收下就行了结果并不是这样的于是出现了报错我输出了一下 NSDate的对象date 发现为NSCFString 所以报错

于是用另一种方法

- (void)dateTest
{
    NSString *path = [[NSBundle mainBundle]pathForResource:@"information.plist" ofType:nil];
    NSArray *dataArray = [NSArray arrayWithContentsOfFile:path];
    NSDictionary *messageDic = dataArray[1];
    NSString *timeStr = messageDic[@"MY_player_event_time"];
    NSString*string;
    string = [timeStr substringToIndex:19];//截取下标19之前的字符串
    NSLog(@"string %@",string);
    
    NSLog(@"class%@",timeStr.class);
    
    NSDate *nowDate = [NSDate date];
    NSLog(@" %@",nowDate.class);
    
//    if ([nowDate earlierDate:timeStr]) {
//        NSLog(@"%@,%@",nowDate,timeStr);
//    }
    
    NSLog(@"----- %@", [self dateFromString:string]);
    

}

- (NSDate *)dateFromString:(NSString *)dateString{
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat: @"yyyy-MM-dd HH:mm:ss"];
    NSDate *destDate= [dateFormatter dateFromString:dateString];
    return destDate;
}

NSCFStr
