self.databaseName=#"App_Database.sqlite";
FMDatabase *database=[self openDatabase: self.databaseName];
[database open];
NSArray *nsarr= [self storeDatabaseColumnInArray: database: query:column];
[database close];
}

Answer 1

Update the OpenMyDatabase method to return the array (note I changed its return type from NSMutableArray * to NSArray *):
- (NSArray *)OpenMyDatabase:(NSString *)query
column:(NSString *)column
{
self.databaseName=#"App_Database.sqlite";
FMDatabase *database=[self openDatabase: self.databaseName];
[database open];
NSArray *nsarr= [self storeDatabaseColumnInArray: database: query:column];
[database close];
return nsarr; // Added
}
