Question

在运行iOS 5.0.1的iPhone 4中，在Wi-Fi和蜂窝网络上都没有连接Sqlite3数据库。由于这个原因，我的应用程序4次在Itunes Apple商店被拒绝。我正在使用iPhone 3.2 iOS 4.1的XCode 3.2.4。这个应用运行良好的地方。

我写下这些代码 -

/// @ AppDelegate.m file 

-(void)createDatabaseIfNeeded {

BOOL success;
NSError *error;

//FileManager - Object allows easy access to the File System.
NSFileManager *FileManager = [NSFileManager defaultManager];

//Get the complete users document directory path.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

//Get the first path in the array.
NSString *documentsDirectory = [paths objectAtIndex:0];


//Create the complete path to the database file.
NSString *databasePath = [documentsDirectory stringByAppendingPathComponent:@"passmanager.sqlite"];

//Check if the file exists or not.
success = [FileManager fileExistsAtPath:databasePath];

//If the database is present then quit.
if(success) return;

//the database does not exists, so we will copy it to the users document directory]
NSString *dbPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"passmanager.sqlite"];

//Copy the database file to the users document directory.
success = [FileManager copyItemAtPath:dbPath toPath:databasePath error:&error];

//If the above operation is not a success then display a message.
//Error message can be seen in the debugger's console window.
if(!success)
    NSAssert1(0, @"Failed to copy the database. Error: %@.", [error localizedDescription]);
}


-(void)applicationDidFinishLaunching:(UIApplication *)application{

// createDatabaseIfNeeded method for first time to create database in new iPhone
[self createDatabaseIfNeeded];
[window addSubview:navigationController.view];
[window makeKeyAndVisible];

}

并且Error在某些ViewController页面的代码

中给Apple带来了压缩

// @ viewController.m

sqlite3 *database;

int result = sqlite3_open("passmanager.sqlite", &database);

if(result != SQLITE_OK){
sqlite3_close(database);
UIAlertView *alert = 
[[UIAlertView alloc] initWithTitle:@"Database Connected" 
                       message:@"No" 
                      delegate:self 
                     cancelButtonTitle:@"OK" 
                     otherButtonTitles:nil]; 

[alert show];     
[alert release];            
}
else{ 
  // some stuff
}

每次Apple都抱怨如果条件为“数据库连接否” 在我的系统中，其他部分正在执行。请帮我。 Thax先进。

您尝试打开的数据库路径看起来不完整，应该是

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *databasePath = [documentsDirectory stringByAppendingPathComponent:@"passmanager.sqlite"];

int result = sqlite3_open([databasePath UTF8String], &database);

因为这是您在createDatabaseIfNeeded

中设置的内容
