Jos*_*ane 3 iphone object objective-c nsarray
NSInteger*count = [monLessonArrayA count]; for(i = 0; i <count; i ++){arrayVar = [monLessonArrayA objectAtIndex:i]; }
我得到一个错误,说我是未申报的,我怎么能将objectAtIndex设置为i所以我可以循环增加它每次?
谢谢.
因为你的未申报.
for (int i = 0; i < count; i++)

此外,你不需要*为你的NSInteger.
NSInteger count = [monLessonArrayA count];
