我有一个名为 [self.places objectAtIndex:indexPath.row] 的数组；我正在尝试输出到表格中。数组中充满了对象，但我想使用对象内部的数据将它们分配给对象的最佳方法是什么？数组里面的数据如下：
<Place:eXMSFqDg7B> {
Location = "<PFGeoPoint: 0x6887480>";
addressline1 = "address line 1";
addressline2 = "address line 2";
agerestrictions = "18+";
email = "test@aol.com";
image = "<PFFile: 0x6887af0>";
name = "Rain NightClub";
phone = 0123456789;
postcode = BT11TG;
type = Club;
}
2012-04-17 00:29:59.501 ClubsNIparse[3517:f803] <Place:95KvPCrSY1> {
Location = "<PFGeoPoint: 0x6888330>";
addressline1 = "address line 1";
addressline2 = "address line 2";
agerestrictions = "18+";
email = "test@aol.com";
image = "<PFFile: 0x6888950>";
name = "Box NightClub";
phone = 0123456789;
postcode = BT11TG;
type = Club;
}
2012-04-17 00:29:59.502 ClubsNIparse[3517:f803] <Place:6AxpfrY0DZ> {
Location = "<PFGeoPoint: 0x6889260>";
addressline1 = "address line 1";
addressline2 = "address line 2";
agerestrictions = "18+";
email = "test@aol.com";
image = "<PFFile: 0x6889880>";
name = Laverys;
phone = 0123456789;
postcode = BT11TG;
type = Club;
}
谢谢。

正如建议的那样，创建了一个 NSObject 并分别设置字段但收到此错误：2012-04-17 11:09:08.363 ClubsNIparse[4906:f803] -[PFObject Location]: unrecognized selector sent to instance 0x6b4e4a0 2012-04-17 11 ：09：08.364 ClubsNIparse [4906：f803] *由于未捕获的异常'NSInvalidArgumentException'而终止应用程序，原因：'-[PFObject Location]：无法识别的选择器发送到实例0x6b4e4a0'*第一次抛出调用堆栈：（0x19d5052 0x1f89d0a 0x19d6ced 0x193bf0034144x 0xc01e0f 0xc02589 0xbeddfd 0xbfc851 0xba7301 0x19d6e72 0x1a992d 0x1b3827 0x139fa7 0x13bea6 0x1c730c 0xb79530 0x19a99ce 0x1940670 0x190c4f6 0x190bdb4 0x190bccb 0x251f879 0x251f93e 0xb68a9b 0x2722 0x2695）终止叫做抛出exceptionCurrent
