UIPopoverController w/MonoTouch.Dialog 会导致弹出框不必要的大小调整
我在 UIPopoverController 中使用 MonoTouch.Dialog 为我们的 iPad 用户提供一系列可使用的设置。在我的应用程序中,我使用这个 CalendarView (http://escoz.com/blog/monotouch-calendar-control-is-here/),以便用户可以设置应用程序的日期(这些设置用于配置定时位置)谷歌地图)。
无论如何,我遇到了一些有关 UIPopoverController 的大小问题...无论我如何设置内容大小,一旦我深入单击 .Dialog 树,UIPopoverController 就会调整自身大小,这会导致所述日历视图上出现不需要的大小调整。
随附的是我所看到的示例。您会注意到,我的内容大小为 450x420。一旦我单击任何选项,弹出窗口就会自行调整大小。我希望这个弹出窗口始终保持相同的大小。
我在这里遗漏了一些明显的东西吗?任何帮助将不胜感激。
从 myPopOverView.cs 声明并启动弹出框:
UIPopoverController myPopOver = new UIPopoverController(new myPopOverView());
btnSearch.TouchUpInside += (sender, e) => {
myPopOver.PopoverContentSize = new SizeF(450f, 420f);
myPopOver.PresentFromRect (btnPopOver.Frame, this.View, UIPopoverArrowDirection.Down, true);
}
从 myPopOverView.cs:
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
var root = CreateRoot ();
var dv = new DialogViewController (root, true);
this.PushViewController (dv, true);
}
RootElement CreateRoot ()
{
return new RootElement ("Find Stuff") {
new Section (){
new RootElement ("States", new RadioGroup (0)){
new Section (){
new RadioElement ("New York"),
new RadioElement ("California"),
new RadioElement ("Texas"),
}
} ,
} ,
new Section (){
new RootElement ("Places", new RadioGroup (0)){
new Section (){
new RadioElement ("New York City"),
new RadioElement ("San Francisco"),
new RadioElement ("Dallas"),
}
} ,
} ,
new Section (){
new RootElement ("Products") {
from sh in "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
select new Section (sh + " - Section") {
from filler in "12345"
select (Element) new CheckboxElement (sh + " - " + filler, true, "kb")
}
} ,
}
} ;
}
I am using MonoTouch.Dialog within a UIPopoverController to give our iPad users a series of settings to work with. In my app, I am using this CalendarView (http://escoz.com/blog/monotouch-calendar-control-is-here/) so the user can set dates for the application (the settings are used to configure timed locations on a Googlemap).
Anyway, I am experiencing some sizing issues concerning the UIPopoverController... Regardless of how i set the content size, once i click deeper into the tree of .Dialog, the UIPopoverController resizes itself which is causing undesired sizing on said calendar view.
Enclosed is a sample of what Im seeing. You will notice, I have the content sized at 450x420. Once I click any of the options, the popover resizes itself. I want this popover to remain the same size all of the time.
Am I missing something obvious here? Any help would be much appreciated.
Declares and launches popover from myPopOverView.cs:
UIPopoverController myPopOver = new UIPopoverController(new myPopOverView());
btnSearch.TouchUpInside += (sender, e) => {
myPopOver.PopoverContentSize = new SizeF(450f, 420f);
myPopOver.PresentFromRect (btnPopOver.Frame, this.View, UIPopoverArrowDirection.Down, true);
}
from myPopOverView.cs:
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
var root = CreateRoot ();
var dv = new DialogViewController (root, true);
this.PushViewController (dv, true);
}
RootElement CreateRoot ()
{
return new RootElement ("Find Stuff") {
new Section (){
new RootElement ("States", new RadioGroup (0)){
new Section (){
new RadioElement ("New York"),
new RadioElement ("California"),
new RadioElement ("Texas"),
}
} ,
} ,
new Section (){
new RootElement ("Places", new RadioGroup (0)){
new Section (){
new RadioElement ("New York City"),
new RadioElement ("San Francisco"),
new RadioElement ("Dallas"),
}
} ,
} ,
new Section (){
new RootElement ("Products") {
from sh in "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
select new Section (sh + " - Section") {
from filler in "12345"
select (Element) new CheckboxElement (sh + " - " + filler, true, "kb")
}
} ,
}
} ;
}

每次 TopViewController 更改时,UIPopoverController 都会尝试自动协商其 ContentSize。
您应该通过重写 WillShowViewController 方法并在那里设置 SizeF 来为每个呈现的 UIViewController 设置 ContentSizeForViewInPopover。
Every time the TopViewController changes UIPopoverController will attempt to auto-negotiate it's ContentSize.
You should set the ContentSizeForViewInPopover for each UIViewController being presented by overriding the WillShowViewController method and setting the SizeF there.
