我有以下代码显示内存泄漏的对象最喜欢附近的语句与stringWithUTF8String。由于stringWithUTF8String iPhone内存泄漏
我已经宣布在物业最爱
-(NSMutableArray *) readFavoritesFromDatabase
{
// Check if database is present
[self setDatabaseNameAndPath];
[self checkAndCreateDatabase];
// Setup the database object
sqlite3 *database;
//Initialize favorites array
if (favorites == nil)
{
[favorites release];
favorites = [[NSMutableArray alloc] init];
}
else
{
favorites = nil;
[favorites removeAllObjects];
}
// Open the database from the users file system
if(sqlite3_open([self.dataBasePath UTF8String], &database) == SQLITE_OK)
{
// Setup the SQL Statement and compile it for faster access
const char *sqlStatement = "select * from Favorites";
sqlite3_stmt *compiledStatement;
if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK)
{
// Loop through the results and add them to the favorites array
while(sqlite3_step(compiledStatement) == SQLITE_ROW)
{
// Create Favorite object and add it to the Favorite array
Favorite *favorite = [[[Favorite alloc] init] autorelease];
favorite.cameraID = [NSString stringWithUTF8String:(const char*)sqlite3_column_text(compiledStatement, 0)];
favorite.cameraName = [NSString stringWithUTF8String:(const char*)sqlite3_column_text(compiledStatement, 1)];
favorite.cameraLink = [NSString stringWithUTF8String:(const char*)sqlite3_column_text(compiledStatement, 2)];
[self.favorites addObject:favorite];
//[favorite.cameraID release];
// [favorite.cameraName release];
// [favorite.cameraLink release];
}
// If favorite cameras exists in database, then sort the Favorites array
if([self.favorites count]>0)
{
NSSortDescriptor *favoritesNameSorter = [[NSSortDescriptor alloc] initWithKey:@"cameraName" ascending:YES];
[self.favorites sortUsingDescriptors:[NSArray arrayWithObject:favoritesNameSorter]];
[favoritesNameSorter release];
}
}
// Release the compiled statement from memory
sqlite3_finalize(compiledStatement);
}
// Close the database
if(database !=nil)
{
sqlite3_close(database);
return self.favorites;
}
else
{
return nil;
}
}
请让我知道如何解决这个内存泄漏问题 在此先感谢。
