我在将数据从 SQLite 数据库存储到服务器时遇到问题。 这是我的代码:
NSString *query = @"SELECT ROW,PHOTO1 BLOB,BLG_NAME TEXT,ST_NO TEXT,ST_NAME TEXT,ST_DIR TEXT,MUNI TEXT,PROVINCE TEXT,BLG_TYPE TEXT,BLG_ACC TEXT,BLG_AMN TEXT,LONGI TEXT,LATI TEXT FROM ATTRI4 WHERE FLAG = ?";
sqlite3_stmt *statement;
if(sqlite3_prepare_v2(database, [query UTF8String], -1, &statement, nil) == SQLITE_OK)
{
sqlite3_bind_int(statement,1,0);
while(sqlite3_step(statement)==SQLITE_ROW)
{
NSLog(@"Data==>%@",[NSString stringWithFormat: @"%s",(char *)sqlite3_column_text(statement, 0)]);

问题是，我得到了服务器的响应，但随后控制转到了 [XML parse]，这里我得到了一个异常:
DONE. Received Bytes: 484

最佳答案
如果你设置
[xmlParser setShouldResolveExternalEntities: YES];
你的代表必须有这个方法
parser:foundExternalEntityDeclarationWithName:publicID:systemID:
