我有一个处理数据库操作的对象。它开始与：奇数NSString行为“警告：无法读取符号...”
-(id)init{
databaseName = @"WhoPaidLast.sql";
// I think this one gets it from the app whereas the next one gets it from the phone
// databasePath = [[NSBundle mainBundle] pathForResource:@"WhoPaidLast" ofType:@"sql"];
// Get the path to the documents directory and append the databaseName
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
self.databasePath = [documentsDir stringByAppendingPathComponent:databaseName];
// Execute the "checkAndCreateDatabase" function
[self checkAndCreateDatabase];
return self;
在本月底我检查DB：
-(void) checkAndCreateDatabase{
// Check if the SQL database has already been saved to the users phone, if not then copy it over
BOOL success;
// Create a FileManager object, we will use this to check the status
// of the database and to copy it over if required
NSFileManager *fileManager = [NSFileManager defaultManager];
// Check if the database has already been created in the users filesystem
success = [fileManager fileExistsAtPath:self.databasePath];
// If the database already exists then return without doing anything
if(success) return;
// If not then proceed to copy the database from the application to the users filesystem
// Get the path to the database in the application package
NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:databaseName];
// Copy the database from the package to the users filesystem
[fileManager copyItemAtPath:databasePathFromApp toPath:self.databasePath error:nil];
//[fileManager release];
}
在此之后，当我去使用databasePath我只似乎能够它抛出之前使用一次这个错误：
warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.1 (8G4)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).
我有一个从数据库返回一堆值的函数。第一次使用detabasePath时，它工作正常并输出预期值，第二次抛出上述错误。
这里是函数的开头：
// Setup the database object
sqlite3 *database;
// Init groupsArray
groupsArray = [[NSMutableArray alloc] init];
NSLog(@"r- %@",self.databasePath);
NSLog(@"s- %@",self.databasePath);
// Open the database from the users filessytem
if(sqlite3_open([self.databasePath UTF8String], &database) == SQLITE_OK) {
如果我删除第二个NSLog的函数，那么错误被用于下一次databasePath。如果我删除它，它将为sqlite3_open函数工作，但在下次使用时出错。
如果有人知道我错误的来源和/或我可能做错了什么，我非常感谢你的帮助。
谢谢。
