一、概念
NSMutableArray*tempArray = [NSMutableArrayarray] ;
NSMutableDictionary*dic1 = [NSMutableDictionarydictionary];
dic1[@"code"] =@"0";
dic1[@"value"] =@"更新时间";
NSMutableDictionary*dic2 = [[NSMutableDictionaryalloc]init];
dic2[@"code"] =@"1";
dic2[@"value"] =@"播放量";
[tempArray addObject:dic1];
[tempArray addObject:dic2];
注意点:1.数组没有创建2.添加对象为空,3.数组越界
