As seen in UIDatePicker you can scroll up endlessly (as well as down for that matter). I want to accomplish that too, because I want people to select a date such as: 1 January, 2010 2 January, 2010 ... 30 December, 2010 31 December, 2010 1 January, 2011 .. So it can go on forever. How would I accomplish this? Since I can only give a sp...
Hi all, My app focuses around the UIPicker. I have three components each with a phrase or a long piece of text. Is it possible to change the width of the picker when the user scrolls the picker (to see the whole phrase)? It would also be nice to have it animated too. Any input is greatly appreciated ...

Hi all, I succesfully implemented a UIPickerView. However, I have a problem in selecting values. According to the standard way, I have implemented the method - (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { // method implementation... } The problem is when I try to sel...
Hey Guys, im using a rotated UIPickerView to use it horizontal. This works fine so far. Now i want to get the View/Title of the "clicked" UIPickerView row. The Delegate gives me the opportunity to get the "selectedRow" when the Picker selects a row. I want no event while selecting it i need the event of clicking it. The funny thing is...
Hey I have a view that has a button that when pressed should modally present a UIDatePicker. I have the picker showing up properly, but because it is on its own UIView, it is full height, and looks funny. All I want is to get a really quick date input from the user, more like a UIActionSheet than a UIView. How can I make the UIPicker sl...
I have been working on a horizontal UIPicker, and I've finally gotten the picker and the labels on the picker to both display rotated. But, the issue I'm noticing now is that the labels display in low res with very visible pixelation. Playing with the font values seems to have no effect on the pixelation. I've included my code: //in vie...

I'm writing an application that uses a UIPickerView and is storing each change to the pickers in core data (the name of the app is Wizard Blood in the iTunes store). I've had some success so far in that my -didSelectRow method successfully adds new objects to core data via the following code: // Get context, entity, managedobject from t...
Hi! I'm currently working on a single View with two pickerViews.

In my app I have a UIPickerView as a subview of a table cell's contentView. I disable scrolling in the table view, and the arrangement works fine under normal circumstances. However, I've found that when VoiceOver (or the Accessibility Inspector) is turned on, the app crashes as soon as the picker is due to get focus. The error is: -[U...
I have a UIPickerView which I want to initialise with a large amount of data. The easiest way to maintain this data is in a spreadsheet, and so I have saved it as a CSV. Unfortunately, I am having a lot of difficulty reading this file. (I have read a lot of documents on how to do it, but it just won't read the file. It say's its null.) W...
Hello all. In my project I have a subclass A of a UIPickerView. In Interface Builder I have a UIPickerView whose type I have changed to my subclass A. In another class B, also defined in my code, instantiated in Interface Builder and linked to A via its outlet, it refers to A with an IBOutlet field A *mySubclass. The problem is this: W...
I am trying to get my UIPickerView to have row 0 selected by default (currently, I have to move the view away from it and back to it, otherwise it has no data to act on). As such, I am using the above method. IB was used to build the picker, however, if I set the picker as an IBOutlet, the delegate and datasource lose their connections....
Hi, It may be a simple question but how do I add multiple components to a UIPickerView? I use NSMutableArray to populate one component but I dont know how to populate the others. I also need to change the value of a label when a row is selected. Thanks in advance Kieran ...
Hello! This seems like pretty standard code straight from the doc, so I'm not sure what I am doing wrong... My 3-component picker doesn't look right when it loads, with the selection indicator being placed too low across the picker (so the grey bar is correctly placed, but the clear raised-looking overlay is too low). Then, when I sel...

I have a standard picker (copied out of the docs) with 6 rows. The row count is correctly logged as 6. When I try to select the last row: [delpicker selectRow:5 inComponent:0 animated:NO]; it selects the 4th row instead. But when I try to: [delpicker selectRow:4 inComponent:0 animated:NO]; it selects the correct, 4th, row...
