(来自SQLiteDB.h)
#import <sqlite3.h>
@interface SQLiteDB : NSObject {
NSString *dbPath;
int databaseKey;
sqlite3 *db;
}
//@property (nonatomic, copy) NSString *db;
@property (nonatomic, copy) NSString *dbPath;
@property (nonatomic) sqlite3 *db;
@property (nonatomic) int databaseKey;
@end
=============== (来自SQLiteDB.m)
#import "SQLiteDB.h"
@implementation SQLiteDB
@synthesize db, dbPath, databaseKey;
@end
=============== (来自SampleAppDelegate.m)
#import "ReaderSampleAppDelegate.h"
#import "ReaderSampleViewController.h"
@implementation ReaderSampleAppDelegate
@synthesize window;
@synthesize viewController;
#pragma mark -
#pragma mark Application lifecycle
- (void)applicationDidFinishLaunching:(UIApplication *)application
{
// create the d/b or get the connection value
SQLiteDB *dbInstance = [[SQLiteDB alloc] init]; // Error here <---------
}
==================
错误是:SQLiteDB未声明。
我以为我在SQLiteDB.h中声明了它?我该如何解决这个问题?
