[示例]NSEnumerator-使用枚举类型实现数组的逆序输出

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
@autoreleasepool {
NSMutableArray *array = [NSMutableArray arrayWithObjects:@"3",@"2",@"5",nil];
NSArray* reversedArray = [[array reverseObjectEnumerator] allObjects];
for (id str in reversedArray) {
NSLog(@"%@",str);
}
}
return 0;
}
