问题 How do you make a UIPickerView act like the one with a webview wherein there is a drop down selection box and instead of dropping down like usual websites do, the iphone makes it into a UIPickerView with all the selections in. When you select one, a check becomes visible beside your selection and changes the value of the drop box. And how do you put the "Done" button on top of the UIPickerView to dismiss the UIPickerView ? I already know that [pickerview setHidden:YES] is the method to use to

UIPickerView - 1st row selection does not call didSelectRow

由 守給你的承諾、 提交于 2019-11-27 02:36:31
问题 I have a UIPickerView on my UIView along with a UITextField . I am letting the user select a value from the picker or enter a custom value in the text field. When the user selects any option from the picker, the variable values are changed fine (in the pickerView:didSelectRow:inComponent: ) method. But if the user does not select any value on the picker (coz they want to select the 1st option which is already selected), this method is not called and the selection is not reflected in the

How do you shrink a UIPickerView on the iPhone?

由 萝らか妹 提交于 2019-11-27 00:23:17
I would like to reduce the height of a UIPickerView in my iPhone app, so that it shows only one row and one column. The height of the picker view should be equal to the height of a row. I'm using Interface Builder to construct the UIPickerView , but I can't find an easy way to re-size this control. How do you shrink a UIPickerView ? Actually, you can slightly shrink the whole UIPickerView by applying an affine transform to an enclosing view. For example: CGSize pickerSize = [pickerView sizeThatFits:CGSizeZero]; pickerTransformView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f,

Hide the cursor of an UITextField

由 半腔热情 提交于 2019-11-26 23:49:14
问题 I am using a UITextField with a UIPickerView for its inputView , so that when the user taps the text field, a picker is summoned for them to select an option from. Nearly everything works, but I have one problem: the cursor still flashes in the text field when it is active, which is ugly and inappropriate, since the user is not expected to type into the field and is not presented with a keyboard. I know I could hackily solve this by setting editing to NO on the text field and tracking touches
