Multi-Component Picker (UIPickerView) in SwiftUI

由 扶醉桌前 提交于 2019-12-07 10:24:57
问题 I'm trying to add a three-component Picker (UIPickerView) to a SwiftUI app (in a traditional UIKit app, the data source would return 3 from the numberOfComponents method), but I can't find an example of this anywhere. I've tried adding an HStack of three single-component Pickers, but the perspective is off from what it would be if they were all part of a single Picker. 回答1: Updated answer in pure SwiftUI - in this example the data is of type String . Tested on Xcode 11.1 - may not work on

what is the best jquery multiselect picker for hierarchical data

由 匆匆过客 提交于 2019-12-06 15:36:06
I have a "flat" dropdown picker today with over 200 items. The issue is that the list is actually a hierarchy of data so I wanted to see if there was any picker that can show a hierarchy of data so people can see where each item fits into the overall list. Right now I am concatenating the levels so it would show something like this: level 1 --> level 2 level 1 --> level 2 level 1 --> level 2 --> level 3 but I thought there might be a better UI widget that would make it easier to pick from a list where the list itself has data a different levels. Try this Checkbox Tree EDIT 1 You can customize

How could I make a horizontal picker?

由 喜夏-厌秋 提交于 2019-12-06 11:32:00
问题 I want to make a horizontal picker for my app, but I'm kinda new at all this. Could someone provide an easy to follow guide on how I'd make this? 回答1: The best way is to fake your own using UIScrollView with pagination enabled. It's actually fairly easy, overlaying a scroll view with your own views for custom graphics. 回答2: An open-source horizontal picker component for iOS has just been released on GitHub. It can be added to a UITableViewCell as follows (in tableView:cellForRowAtIndexPath: )

Font size in Picker control in xamarin forms

由 泪湿孤枕 提交于 2019-12-06 03:57:55
问题 I am surprised to see that Picker control does not have font size property to set font size. I had a need to set font size for picker control. Kindly suggest how do I set font size? 回答1: The underlaying scrollable Xamarin.Form Picker list is handled by native controls such as iOS UIPickerView , Android's DatePicker | TimePicker , ... and access to these controls are internal to the PickerRender class. You can create custom renderers for each of your targeted platforms and create custom views

由 放肆的年华 提交于 2019-12-06 02:40:38
问题 I'd like to implement an ios style picker on Android with multiple columns, such as this one: Yes, I know that Android has a slightly different platform default for this kind of UI, but I really like the IOS style that shows the different options above and below and lets you easily drag up and down. I'm already aware of this DateSlider project, but it's specific for dates, and I want to use it for custom lists. And also it uses horizontal scrolling rather than vertical. Thanks! 回答1: I was
