ObjectiveCコードとSQLiteの実装に問題があります。エラー行はNSAsset
if句にあり、コメントアウトされています。コードは次のとおりです。
-(void) createTable: (NSString *) tableName
withField1: (NSString *) field1
withField2: (NSString *) field2
withField3: (NSString *) field3
withField4: (NSString *) field4
{
char *err;
NSString *sql= [NSString stringWithFormat:
@"CREATE TABLE IF NOT EXIST '%@' ( '%@ "
"TEXT PRIMARY KEY, '%@' INTEGER, '%@' INTEGER, '%@' TEXT);",
tableName, field1, field2, field3, field4];
if (sqlite3_exec(db, [sql UTF8String], NULL, NULL, &err)
!= SQLITE_OK) {
sqlite3_close(db);
// NSAssert(0, @"Could not create table");
}else{
NSLog(@"table create");
}
}
-(NSString *) filePath{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
return [[paths objectAtIndex:0]stringByAppendingPathComponent:@"bp.sql"];
}
-(void)openDB{
if (sqlite3_open([[self filePath] UTF8String], &db) !=SQLITE_OK){
sqlite3_close(db);
NSAssert(0, @"Database failed to open");
}else{
NSLog(@"Database open");
}
}
そしてエラーメッセージ:
