    <p>It's possible. Here is how you can do it. First setup a timer. Let's assume <code>int maxNumber</code> is an instance variable set to some arbitrary value.</p> <pre><code>- ( void) viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [self.timer invalidate]; self.timer = [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(timerFireMethod:) userInfo:nil repeats:YES]; } - (void) viewWillDisappear:(BOOL)animated{ [self.timer invalidate]; [super viewWillDisappear:animated]; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. [self.infinitePickerView selectRow:(int)maxNumber*5 inComponent:0 animated:YES]; } </code></pre> <p>In the timer fire method check if any of the 'edge' view of your uipickerview are showing.</p> <pre><code>- (void)timerFireMethod:(NSTimer*)theTimer{ int rowSelected = [self.infinitePickerView selectedRowInComponent:0]; for (int i=0; i&lt;= 20; i++) { UIView * viewBelow = [self.infinitePickerView viewForRow:i forComponent:0]; UIView * viewAbove = [self.infinitePickerView viewForRow:maxNumber*10-20+i forComponent:0]; if(viewBelow!=nil || viewAbove!=nil){ int middlePosition = maxNumber * 5 + (rowSelected % maxNumber); [self.infinitePickerView selectRow:middlePosition inComponent:0 animated:NO]; break; } } } </code></pre> <p>Note this works because <code>[self.infinitePickerView viewForRow:i forComponent:0];</code> returns a UIView only if it's visible.</p> <p>Of course your <code>UIPickerViewDelegate</code> must use be something like</p> <pre><code>- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{ return maxNumber * 10; //returning a large number } //You cannot use this method /* - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{} You have to use the method below in lieu of it */ - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{ UILabel * label; if (!view) { label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.infinitePickerView.bounds.size.width, 30)]; }else { label = (UILabel *) view; } [label setText:[NSString stringWithFormat:@" %d", row % maxNumber]]; return label; } </code></pre> <p>Hope this works!! :) Good luck!</p>

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.

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