it's possible add as item in the uipickerview some images/icons instead of text?
thanks
yes it is absolutely possible. u need to handle pickerView delegate method
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row
forComponent:(NSInteger)component reusingView:(UIView *)view
here you simply return custom view(could be anything UIImage UILabel)
and set userInteractionEnable property to no for customize view..

I'm using some UIPickerView delegate methods only for the brand-new-Ive-modified iOS under NDA, e.g.
-(UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
I don't want to implement them for iOS6, to preserve default iOS behavior, so a condition inside the method won't work. How to do it?
In your delegate, override respondsToSelector: and return NO in case of old OS:
- (BOOL)respondsToSelector:(SEL)selector
{
if (selector == #selector(pickerView:viewForRow:forComponent:reusingView:))
return MyFunctionThatChecksIosVersionIsMinimum7();
return [super respondsToSelector:selector];
}
So you're implementing the delegate method normally. When the picker view is asking your delegate if it understands the message you're simply lying to it.
Hello friends I am displaying text in UIPickerview row. But when the label size is too big then Picker row displays ... at the end of the label.
I want to display whole title in row of Picker instead of this. Can i set the font size automatically as per the title width in pickerview.
You need to implement following method:
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
UILabel* tView = (UILabel*)view;
if (!tView){
tView = [[UILabel alloc] init];
// Setup label properties - frame, font, colors etc
...
}
// Fill the label text here
...
return tView;
}
Make your controller a UIPickerViewDelegate and UIPickerViewDataSource, then you can use this routine to make any custom change you want for your picker row:
-(UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
//make your own view here, it can be a UILabel if you want, or other kind of view.
//You can give it any size font you need.
}
Does anyone know if it is possible to change the font and/or color for individual UIPickerView Items?
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
UILabel* tView = (UILabel*)view;
if (!tView){
tView = [[UILabel alloc] init];
// Setup label properties - frame, font, colors etc
...
}
// Fill the label text here
...
return tView;
}
Yes, it is possible. To do that you need to implement pickerView:viewForRow:forComponent:reusingView: method in picker's delegate - create UILabel instance there and setup it with whatever attributes you want.
For this, I would simply go with attributed strings.
Implement this method is your delegate:
- (NSAttributedString *)pickerView:(UIPickerView *)pickerView
attributedTitleForRow:(NSInteger)row
forComponent:(NSInteger)component
how to call the picker view content in table view..is there any method to call the picker view content?pls help me...
I think you would have used this delegate to put your content into the picker.
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return yourPickerContentArray;
}
I think that yourPickerContentArray will have the content of the picker. why dont you use that array where you want.
Hey! I have a UIPicker, and I am using the function:
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row
forComponent:(NSInteger)component reusingView:(UIView *)view {
But, when you tap one of the views returned by this function, the tapped view does not become highlighed, and selected if the touch is released. How can I fix that?
Make use of this property,
pickerView.showsSelectionIndicator = YES;
at initialization.
