Implicit conversion of 'int' to 'id' is disallowed with ARC

 NSMutableDictionary *dic = [typeArray objectAtIndex:1];
   NSString *typeName = [dic objectForKey:@"type"];
 NSMutableDictionary *infoDic = [dic objectForKey:@"dic"];
 //---------------------------------------------------出错----------------------------------------------------------------------
 NSLog(@"当前cell的InfoDic==%@",infoDic);
 NSMutableArray *allItem = [[NSMutableArray alloc] init];
 for (int i=0; i<[infoDic count]; i++) {
     NSDictionary *contentOfDic = [infoDic objectForKey:[NSNumber numberWithInt:i]];
     NSString *name = [contentOfDic objectForKey:@"sender"];
     [allItem addObject:name];
 }

在NSMutableDictionary中获取key值为int类型的value必须要进行NSNumber转换[NSNumber numberWithInt:i] 否者会报标题上得错误
