iOS10i 数据集转记录集出问题
DatasetVector *datasetVector = (DatasetVector *)layer.dataset;
QueryParameter *parameter = [[QueryParameter alloc]init];
parameter.cursorType = DYNAMIC;
parameter.attriButeFilter = [NSString stringWithFormat:@"from = %@",layer.name];
parameter.spatialQueryMode = SQM_IDENTITY;
Recordset *recordset = [datasetVector query:parameter];
数据集有数据 转成记录集就是空的了
