正在制作一个带有嵌入式SQLite数据库的iOS应用程序。所以我让我的数据库在一个SQLite管理员,并将其拖到我的Xcode项目,就像在教程中说的。 当我尝试打开我的数据库时,出现此错误:“内存不足”。不知道它是SQLite的错误还是什么,但我的文件很小,以避免内存问题。尝试在SQLite中打开数据库的错误(iOS)
这是我的代码初始化我的数据库:
- (id)initWithPath:(NSString *)path {
if (self = [super init]) {
BOOL success;
NSError *error;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *dbPath = [documentsDirectory stringByAppendingPathComponent:@"SoundLib_DB.sqlite"];
if ([fileManager fileExistsAtPath:dbPath] == NO) {
NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"SoundLib_DB" ofType:@"sqlite"];
[fileManager copyItemAtPath:resourcePath toPath:dbPath error:&error];
}
success = [fileManager fileExistsAtPath:dbPath];
if(!success)
{
NSLog(@"Cannot locate database file '%@'.", dbPath);
}
sqlite3 *dbConnection;
//Here is when I get the error, at trying to open the DB
if (sqlite3_open_v2("SoundLib", &dbConnection, SQLITE_OPEN_READWRITE, NULL) != SQLITE_OK) {
NSLog(@"[SQLITE] Unable to open database!");
NSLog(@"%s Prepare failure '%s' (%1d)", __FUNCTION__, sqlite3_errmsg(database), sqlite3_errcode(database));
return nil;
}
database = dbConnection;
}
return self;
}
请输入错误 –
您在'sqlite3_open_v2'调用中没有使用数据库的实际文件路径。 – omz
是的,'sqlite3_open_v2(“SoundLib”,&dbConnection,...'不只是鱼腥味,它是错误的 –
