Scrolling TableView in PageViewController - ios

Question

I have parent and child View controllers, in child view controller I have image view and table view. If table view's content size is less than screen size, it goes properly. But if content size is more than screen size, I can't scroll it.
In XCode Attributes Inspector I have these properties. http://i.stack.imgur.com/yuxZ1.png
My code to generate Table View content:
- (void)viewDidLoad {
[super viewDidLoad];
_mainArray = [self getAnswers];
self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSUInteger)section {
int height = (_imageView.image == 0) ? 0 : 118;
return height;
}
- (NSMutableArray *)getAnswers {
NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"pdd.sqlite"];
const char * dbpath = [defaultDBPath UTF8String];
sqlite3_stmt *statement;
NSMutableArray *array = [[NSMutableArray alloc] init];
if (sqlite3_open(dbpath, &_pdd_ab) == SQLITE_OK) {
NSString *querySQL = [NSString stringWithFormat:#"SELECT RecNo, Picture, Question, Answer1, Answer2, Answer3, Answer4, Answer5, RightAnswer, Comment FROM paper_ab WHERE PaperNumber = \"%#\" AND QuestionInPaper = \"%d\"", _randomNumbers[_index] , (int)_index + 1];
const char * query_stmt = [querySQL UTF8String];
if (sqlite3_prepare_v2(_pdd_ab, query_stmt, -1, &statement, NULL) == SQLITE_OK) {
if (sqlite3_step(statement) == SQLITE_ROW) {
NSData *picture = [[NSData alloc] initWithBytes:sqlite3_column_blob(statement, 1) length: sqlite3_column_bytes(statement, 1)];
_imageView.image = [UIImage imageWithData:picture];
for (int i = 2; i < 10; i++) {
if (sqlite3_column_text(statement, i) != NULL) {
NSString *arrayelement = [[NSString alloc]
initWithUTF8String:
(const char *) sqlite3_column_text(statement, i)];
[array addObject:arrayelement];
}
}
sqlite3_finalize(statement);
} else {
NSLog(#"Rezultatov net!");
}
} else {
NSLog(#"Ne mogu vypolnit' zapros!");
}
sqlite3_close(_pdd_ab);
} else {
NSLog(#"Ne mogu ustanovit' soedinenie!");
}
return array;
}

If I change properties "Bounces" and "Bounce Vertically" of Scroll View to enabled, I can scroll table view, but it return to its original state. You can see this situation on YouTube http://www.youtube.com/watch?v=5rDd4oQQDB0
So, my question is how to scroll UITableView in UIPageViewController if table content size is more than screen size?

Answer 1

You have to set bottom space to super view auto layout to your table-view manage scrolling according to device screen size.Bottom space to super-view auto-layout adjust your table-view bottom according to device screen size.
