сначала скопируйте базу данных из ресурса в каталог dir:
- (void) checkAndCreateDatabase
{
NSString *database_Name =@"quizDB.sqlite"
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *database_Path = [documentsDir stringByAppendingPathComponent:database_Name];
NSFileManager *fileManager = [NSFileManager defaultManager];
if(![fileManager fileExistsAtPath:database_Path])
{
NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:database_Name];
[fileManager removeItemAtPath:database_Path error:nil];
[fileManager copyItemAtPath:databasePathFromApp toPath:database_Path error:nil];
}
else
{
NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:database_Name];
[fileManager copyItemAtPath:databasePathFromApp toPath:database_Path error:nil];
}
}
, а после обновления базы данных:
- (void) UpdateDatabase
{
sqlite3 *contactDB;
sqlite3_stmt *updateStmt;
NSString *database_Name =@"quizDB.sqlite"
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
NSString *dbpath = [documentsDir stringByAppendingPathComponent:database_Name];
if(sqlite3_open([dbpath UTF8String], &contactDB) == SQLITE_OK)
{
NSString *querySql=[NSString stringWithFormat:@"Update quiz set etat=1 where id=\"%i\"",id_quiz];
const char*sql=[querySql UTF8String];
if(sqlite3_prepare_v2(contactDB,sql, -1, &updateStmt, NULL) == SQLITE_OK)
{
if(SQLITE_DONE != sqlite3_step(updateStmt))
{
NSAssert1(0, @"Error while updating. '%s'", sqlite3_errmsg(contactDB));
}
else{
sqlite3_reset(updateStmt);
NSLog(@"Update done successfully!");
}
}
sqlite3_finalize(updateStmt);
}
sqlite3_close(contactDB);
}
и проверьте свою базу данных, которая сохраняется в каталоге документов, а не в ресурсе
