This issue started happening in iOS7 with the new UIPickerView controller. To use images in your UIPickerView controller you must use the delegate method to return an image: pickerView:viewForRow:forComponent:reusingView: The problem is that the screen subsequently exhibits all kinds of strange behavior - the image views disappear as you move your finger up and down the control. This is a solution posted on a dev forum which works as of iOS 7.0.2: - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view { // self

I would like to change the white background in a UIPickerView to an image of my own. Is this possible? Also, I have managed to get my UIPickerView to scroll horizontally instead of vertical. Now, I would like to know if there is any way to adjust the spacing between two rows of the picker view? I have attached an image to show what I mean. This is my code: - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view from its nib. arrayDays = [[NSMutableArray alloc] init]; [arrayDays addObject:@"ONSDAG"]; [arrayDays addObject:@"TORSDAG"]; [arrayDays addObject:@

I have observed that UIPicker always remains in black color, Is there any way to change the color of UIPicker & it's Selection Indicator? Thanks for helping me. I assume all you want to change is the color of the border of the picker, not of the region in the center with which the user interacts. In this case, do the following: Create 4 "cover" UIViews and add them directly to the UIPicker, as in: [picker addSubview: coverView]; Position these views over the top, bottom, left and right sides of the picker border. (You will need to experiment with sizes.) Set the backgroundColor of the

The UIPickerView that appears in Safari has a check mark beside the current choice. Is there a built-in way to get this, or do I have to program it up myself? If I do have to create it, can anyone point me to some code to do this? Thanks You need to implement -pickerView:viewForRow:forComponent:reusingView: from the UIPickerViewDelegate. You have to create a view, that contains a UIButton with the checkmark image, and return it from -pickerView:viewForRow:forComponent:reusingView: Here is some official sample code for customizing UIPicker view: http://developer.apple.com/library/ios/

I am a .NET programmer and new to Objective C. I am trying to make a UIPickerView which acts like a .NET dropdownlist. User sees the list of text and selects one and the selected value (which is the ID) is used in code. I have been browsing for almost half a day trying to figure this out. I could add a regular PickerView with list of strings, picker view with mulitple components and picker view with dependent components none of which seems to answer my query. Please help. You can use a NSDictionary as a data source for UIPickerView but if you have a custom NSObject that already contains the
