你能發現任何會導致它不起作用的東西嗎?刪除SQLITE行UITABLEVIEW
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
int record_to_delete = [[[data objectAtIndex:indexPath.row] recordID] integerValue];
[data removeObjectAtIndex:indexPath.row];
[self.tableView deleteRowsAtIndexPaths:[NSMutableArray arrayWithObject:indexPath] withRowAnimation:YES];
//Delete from TABLENAME where CRITERIA1=VALUE1 (AND CRITERIA2=VALUE2...)
//Delete from Data where RecordID=xxx
sqlite3 *database;
if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) {
NSString *sqlStatement = [NSString stringWithFormat:@"delete from Data where RecordID = %d",record_to_delete];
NSLog(@"Statement is: %@", sqlStatement);
sqlite3_stmt *compiledStatement;
NSLog(@"Statement");
if(sqlite3_prepare_v2(database, [sqlStatement UTF8String], -1, &compiledStatement, NULL) == SQLITE_OK){
}
NSLog(@"Deleting");
sqlite3_finalize(compiledStatement);
NSLog(@"Deleted");
}
sqlite3_close(database);
}
}
SQL語句在我的數據庫軟件中執行時工作正常。但是,在iPhone模擬器上運行時,它不會從數據庫中刪除它。任何幫助將不勝感激。對不起,我不能更具體。
感謝

2013-03-18 18:45:07.212 Navigation[842:c07] Deleting
2013-03-18 18:45:07.213 Navigation[842:c07] Deleted
UPDATE:設法得到它的工作。我只是想念。
sqlite3_step(compiledStatement)
無論如何,謝謝。
打開數據庫?你能否把你的問題和日誌一起包括在內? – 2013-03-18 18:41:21
xcode刪除設備上的數據庫對我來說是新消息。 – 2013-03-18 18:41:23
