I've got two controls on an iPhone screen - a TableView and a UIPickerView. When you select the single cell in the TableView you're taken to another screen where you're show a list of clothing types. Selecting a single clothing item from the list takes you back to the first screen. Based on your selection, the number of components in the UIPickerView is changed (1-4) and each component is populated with relevant data. Let's say you have three items in you clothing type list and each item should have a certain number of components in the UIPickerView when it is selected: Belt - 3 components

Hi I am using picker view , by default it is selecting the first row. I don't want this option. For example I am having "No" and "yes" options.If i give this option in pickerview "No " will be selected in pickerview (attached screenshot).I dont need this.I need first row as empty .once the user selects on "No" or "Yes" then only it need to show as a selected row. Related screenshot attached below. How to this? thanks in advance. If you want to get this one by using UIPickerView then pass the first component of the picker view as a empty value,otherwise you can use custom pickerview .

Check 3 screenshots here first. Screenshot 1 : Subject is UITextview field. When I tap on subject text field normal keyboard will come. There is no problem here now.

My Problem : When I click Priority textfield directly from Subject textview by scrolling without using done button or next button from keyboard. Then following issue is arriving. or when I move UITextview to other any other Text Field like in

Regarding implementation of multi component dependent uipickerview

问题 I am having trouble grasping the concept of multi component uipickerviews. I really would like to just OWN this subject. I would like to make a 4 component pickerview with components that are dependent on one another. The first component is being populated from an array from my db, and that is showing up fine. I have all of the other info available in arrays, but I am just getting hung up on the dependent aspect of my pickerview. I figure the best way to make component 2's data depend on comp

问题 I have a UIPickerView displayed inside a UIPopoverController . The dimensions of the UIPickerView are: 320x216 . For some reason, the UIPickerView seems to be ~3/5 of the proper height, and the UIPopoverController spans all the way down to the bottom of the screen. Please see the code below. Thanks! self.picker = [[[UIPickerView alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height+44, 320, 216)] autorelease]; self.picker.backgroundColor = [UIColor clearColor]; self.picker

问题 I want to display a picker when the user clicks on a button I subclassed the UIButton and changed its inputview so that it is writable.

问题 I have a UIPickerView in the footer of a table (from which I plan to issue "pagination"-style requests for the table--the picker will list the pages available of the LARGE data set I'm navigating, and let the user jump straight to any "page" of the data). My picker receives taps; if I tap on a row of the picker that isn't the selected one, it rolls into the center space of the picker. But if I drag my finger on the picker, I scroll the TABLE, not the picker contents. I tried installing a
