Which options do I have for longer option strings? - ios

Question

As we can see on the bottom of the screen, there are options to be chosen.
Which other options are there for this menu such that I can display longer strings fully?

Answer 1

For your requirement you have to make a customize one to do it:
Try to use this code:
using System;
using System.Collections.Generic;
using CoreGraphics;
using UIKit;
namespace CusActionSheet
{
public delegate void OneParameterEventHandler<T>(T data);
public class ALActionSheet : UIView
{
private nfloat maximumProportion = 0.8f;
public event OneParameterEventHandler<string> RowClicked;
//You also can use this if you don't know the generic(but remeber also change it for source):
//public delegate void OneParameterEventHandler(string data);
//public event OneParameterEventHandler SelectedPhoneNumber;
private UIView backgroundContainer;
private UIView topContainer;
private UILabel topContainerTitleView;
private UITableView topContainerTable;
private ALActionSheetSource topContainerTableSource;
private UIButton btnCancel;
private nfloat itemPadding = 10;
private nfloat itemHeight = 60;
private nfloat cornerRadius = 10;
private List<string> dataList;
private CGRect backContainerShownFrame;
private CGRect backContainerHiddenFrame;
private string selectedNumber;
public CGRect BackContainerShownFrame
{
get
{
return backContainerShownFrame;
}
set
{
backContainerShownFrame = value;
}
}
public ALActionSheet(List<string> _dataList)
{
this.BackgroundColor = UIColor.Clear;
this.dataList = _dataList;
backgroundContainer = new UIView();
backgroundContainer.Layer.CornerRadius = cornerRadius;
backgroundContainer.Layer.MasksToBounds = true;
topContainer = new UIView();
topContainer.BackgroundColor = UIColor.White;
topContainer.Layer.CornerRadius = cornerRadius;
topContainer.Layer.MasksToBounds = true;
topContainerTitleView = new UILabel();
topContainerTitleView.Text = "Select a number";
topContainerTitleView.TextAlignment = UITextAlignment.Center;
topContainerTitleView.BackgroundColor = UIColor.FromRGB(230, 230, 230);
topContainer.AddSubview(topContainerTitleView);
topContainerTableSource = new ALActionSheetSource(dataList);
topContainerTableSource.RowClicked += (data) =>
{
selectedNumber = data;
Close();
};
topContainerTable = new UITableView();
topContainerTable.RowHeight = itemHeight;
topContainerTable.Layer.CornerRadius = cornerRadius;
topContainerTable.Layer.MasksToBounds = true;
topContainerTable.BackgroundColor = UIColor.White;
topContainerTable.Source = topContainerTableSource;
topContainer.AddSubview(topContainerTable);
btnCancel = new UIButton(UIButtonType.System);
btnCancel.SetTitle("Cancel", UIControlState.Normal);
btnCancel.TitleLabel.Font = UIFont.SystemFontOfSize(18);
btnCancel.BackgroundColor = UIColor.White;
btnCancel.Layer.CornerRadius = cornerRadius;
btnCancel.Layer.MasksToBounds = true;
btnCancel.TouchUpInside += delegate
{
Close();
};
backgroundContainer.AddSubview(topContainer);
backgroundContainer.AddSubview(btnCancel);
Layout();
}
public void Layout()
{
this.Frame = UIScreen.MainScreen.Bounds;
nfloat tableMaxHeight = UIScreen.MainScreen.Bounds.Height * maximumProportion - 2 * itemPadding - 2 * itemHeight;
nfloat tableHeight = dataList.Count * itemHeight < tableMaxHeight ? dataList.Count * itemHeight : tableMaxHeight;
nfloat itemWidth = UIScreen.MainScreen.Bounds.Width - 2 * itemPadding;
nfloat backgroundContainerHeight = tableHeight + 2 * itemHeight + itemPadding;
backgroundContainer.Frame = new CGRect(0, 0, itemWidth, backgroundContainerHeight);
nfloat topContainerHeight = itemHeight + tableHeight;
topContainer.Frame = new CGRect(0, 0, itemWidth, topContainerHeight);
topContainerTitleView.Frame = new CGRect(0, 0, itemWidth, itemHeight);
topContainerTable.Frame = new CGRect(0, itemHeight, itemWidth, tableHeight);
btnCancel.Frame = new CGRect(0, topContainerHeight + itemPadding, itemWidth, itemHeight);
BackContainerShownFrame = new CGRect(new CGPoint(itemPadding, UIScreen.MainScreen.Bounds.Height - backgroundContainerHeight - itemPadding), backgroundContainer.Bounds.Size);
backContainerHiddenFrame = new CGRect(new CGPoint(itemPadding, UIScreen.MainScreen.Bounds.Height + itemPadding), backgroundContainer.Bounds.Size);
}
public void Show()
{
UIApplication.SharedApplication.KeyWindow.AddSubview(this);
backgroundContainer.Frame = backContainerHiddenFrame;
this.AddSubview(backgroundContainer);
UIView.Animate(0.3, delegate
{
this.BackgroundColor = UIColor.FromRGBA(0, 0, 0, 0.5f);
backgroundContainer.Frame = BackContainerShownFrame;
});
}
public void Close()
{
UIView.Animate(0.3, delegate
{
backgroundContainer.Frame = backContainerHiddenFrame;
this.BackgroundColor = UIColor.Clear;
}, delegate
{
this.RemoveFromSuperview();
if (null != RowClicked && null != selectedNumber)
RowClicked(selectedNumber);
});
}
}
class ALActionSheetSource : UITableViewSource
{
public event OneParameterEventHandler<string> RowClicked;
private string cellID = "ALActionSheetCell";
private List<string> dataList;
public ALActionSheetSource(List<string> _dataList)
{
dataList = _dataList;
}
public override nint RowsInSection(UITableView tableview, nint section)
{
return dataList.Count;
}
public override UITableViewCell GetCell(UITableView tableView, Foundation.NSIndexPath indexPath)
{
UITableViewCell cell = tableView.DequeueReusableCell(cellID);
if (null == cell)
{
cell = new UITableViewCell(UITableViewCellStyle.Default, cellID);
cell.TextLabel.TextAlignment = UITextAlignment.Center;
//cell.TextLabel.AdjustsFontSizeToFitWidth = true;//Auto resize by content
cell.TextLabel.Lines = int.MaxValue;//Multiple lines
}
cell.TextLabel.Text = dataList[indexPath.Row];
return cell;
}
public override void RowSelected(UITableView tableView, Foundation.NSIndexPath indexPath)
{
if (null != RowClicked)
RowClicked(dataList[indexPath.Row]);
}
}
}
And invoke it like this:
public override void ViewDidLoad()
{
base.ViewDidLoad();
// Perform any additional setup after loading the view, typically from a nib.
List<string> testList = new List<string>();
for (int i = 0; i < 10; i++) {
testList.Add("Item " + i.ToString());
}
testList.Add("I'm a very very very very very very very very long text.");
ALActionSheet actionSheet = new ALActionSheet(testList);
actionSheet.RowClicked += (data) => {
Console.WriteLine("data = "+data);
};
UIButton btnTest = new UIButton(UIButtonType.System);
btnTest.SetTitle("Test", UIControlState.Normal);
btnTest.Frame = new CoreGraphics.CGRect(50, 50, 80, 30);
btnTest.TouchUpInside += delegate {
actionSheet.Show();
};
this.Add(btnTest);
}
Hope it can help you.
