例1. NSMutableDictionary *dicPara = [NSMutableDictionary dictionaryWithObjectsAndKeys:_address,@"address",lonti,@"longtitude",lati,@"latitude",_poiname,@"poiname",_province,@"province",_city,@"city",_district,@"district",_street,@"street",nil];
例2. NSMutableDictionary *dicPara = [NSMutableDictionary dictionaryWithObjectsAndKeys:_addressL,@"address",lonti,@"longtitude",lati,@"latitude",remark,@"remark",customer_id,@"customer_id",nil];
[dicPara setObject:POIName forKey:@"poiname"];
[dicPara setObject:province forKey:@"province"];
[dicPara setObject:city forKey:@"city"];
[dicPara setObject:district forKey:@"district"];
[dicPara setObject:street forKey:@"street"];

例1是我开始写的，打印字典，发现里面的值有一部分不存在的
然后我采取了下面例2的赋值方法，发现赋值成功了虽然成功了，但是我不知道原因是什么，请大神指点迷津
