Question

这是我的数据库的代码 SQLiteTutorialAppDelegate.m

$ .-（void）readAnimalsFromDatabase {

sqlite3 *database;
animals = [[NSMutableArray alloc] init];
if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) {

    const char *sqlStatement = "select * from animals";
    sqlite3_stmt *compiledStatement;
    if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
        while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
            // Read the data from the result row
            NSString *aName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)];
            NSString *aDescription = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)];
            NSString *aImageUrl = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 3)];

            // Create a new animal object with the data from the database
            Animal *animal = [[Animal alloc] initWithName:aName description:aDescription url:aImageUrl];

            // Add the animal object to the animals Array
            [animals addObject:animal];

            [animal release];
        }
    }

    sqlite3_finalize(compiledStatement);

}
sqlite3_close(database);

}

和RootViewController.m

$ .-（void）searchBar：（UISearchBar *）SearchBar textDidChange：（NSString *）searchText {

[copyListOfItems removeAllObjects];
NSMutableArray *searchArray = [[NSMutableArray alloc] init];
SQLiteTutorialAppDelegate *appDelegate = (SQLiteTutorialAppDelegate *)[[UIApplication sharedApplication] delegate];

for（appAlegate.animals中的NSArray * rowArray） { for（NSAtring * aName in rowArray）

    {

        [searchArray addObject:rowArray]; // HERE CRASH 
    }
}


for (NSString *sTemp in searchArray)
{
    NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];

    if (titleResultsRange.length == 0)
        [copyListOfItems addObject:sTemp];
}

[self.tableView reloadData];

}
