我如何获取储存在阵列中的物体的特性?
例如:
[myArray objectAtIndex:0].intProperty = 12345;
你们首先必须投下这个物体。
<代码>(MyObjectType *) [my Array ObjectAtIndex:0]intProperty = 12345;
首先,你们需要将国际发展研究中心储存在一个变数中,如上。
(id) myObject = [myArray objectAtIndex:0];
然后,你可以操纵:
myObject.intProperty = 12345;
并再次储存:
[myArray removeObjectAtIndex:0]; // Remove it before setting it again
[myArray insertObject:myObject atIndex:0];
EDIT:或者你可以使用Jacob的行文,这更能:
通过综合集造物确定财产的时间较短(我认为更清洁地阅读和理解):
[[myArray objectAtIndex:0] setIntProperty:12345];
