    <p><a href="https://www.dropbox.com/s/luyezfrj84dj4cn/SidebarLesson.zip" rel="nofollow">My source code download</a> </p> <p>------Updated--------</p> <p>I am trying to implement a sidebar effect using <code>CGAffineTransformMakeTranslate</code> simulate slide-in and slide-out. I want to make my sidebar as a scrollview so it could be add more data but it can not scroll at all.</p> <p>Here is my code:</p> <p><code>SidebarView</code> is a <code>UITableView</code></p> <pre><code>#import "SidebarView.h" @interface SidebarView () @property (nonatomic, readwrite) CGFloat offsetX; @end @implementation SidebarView #pragma mark - Initilization - (void)setup { // do initilization here self.offsetX = self.frame.size.width; [self registerClass:[UITableViewCell class] forCellReuseIdentifier:@"sidebarCell"]; } - (void)awakeFromNib { [self setup]; } - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; [self setup]; return self; } #pragma mark - Custom function - (void)show { self.transform = CGAffineTransformMakeTranslation(-self.offsetX, 0); } - (void)hide { self.transform = CGAffineTransformMakeTranslation(-self.offsetX, 0); } </code></pre> <p>And my view controller:</p> <pre><code>#import "ViewController.h" #import "SidebarView.h" @interface ViewController () &lt;UITableViewDataSource&gt; @property (nonatomic) BOOL isMenuHide; @property (nonatomic, strong) SidebarView *sidebarView; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.isMenuHide = YES; // Do any additional setup after loading the view, typically from a nib. } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; if (self.sidebarView) { self.sidebarView = nil; } if (self.view) { self.view = nil; } } - (SidebarView *)sidebarView { if (!_sidebarView) { CGRect frame = [[UIScreen mainScreen] bounds]; frame.size.width /= 2; _sidebarView = [[SidebarView alloc] initWithFrame:frame]; _sidebarView.transform = CGAffineTransformMakeTranslation(-_sidebarView.offsetX, 0); _sidebarView.contentSize = CGSizeMake(320, 960); _sidebarView.scrollEnabled = YES; _sidebarView.showsVerticalScrollIndicator = YES; _sidebarView.dataSource = self; } return _sidebarView; } #define ANIMATE_DURATION 0.5 - (IBAction)showMenu:(UIBarButtonItem *)sender { if (self.isMenuHide) { [self.view addSubview:self.sidebarView]; [UIView animateWithDuration:ANIMATE_DURATION animations:^{ [self.sidebarView show]; self.view.transform = CGAffineTransformMakeTranslation(self.sidebarView.offsetX, 0); }]; } else { [UIView animateWithDuration:ANIMATE_DURATION animations:^{ [self.sidebarView hide]; self.view.transform = CGAffineTransformMakeTranslation(0, 0); } completion:^(BOOL finished) { [self.sidebarView removeFromSuperview]; }]; } self.isMenuHide = !self.isMenuHide; } #pragma mark - UITableView Datasource - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 11; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"sidebarCell"]; cell.textLabel.text = @"Bingo"; return cell; } @end </code></pre> <p>Please tell my "why my scrollview cannot scroll" thanks.</p>

    1. COits confusing whether you are adding scrollview in a tableview or tableview in a scrollview. By the way tableview inherits scrollview

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
