第一步，控制器先来个属性 @property (strong, nonatomic) MBProgressHUD *HUD; 第二步，显示与隐藏的调用方法 - (void)hudTipWillShow:(BOOL)willShow{ if (willShow) { [self resignFirstResponder]; UIWindow *keyWindow = [UIApplication sharedApplication].keyWindow; if (!_HUD) { _HUD = [MBProgressHUD showHUDAddedTo:keyWindow animated:YES]; _HUD.mode = MBProgressHUDModeDeterminateHorizontalBar; _HUD.labelText = @"正在上传图片..."; _HUD.removeFromSuperViewOnHide = YES; }else{ _HUD.progress = 0; [keyWindow addSubview:_HUD]; [_HUD show:YES]; } }else{ [_HUD hide:YES]; } } 第三步，上传前，让其显示 [self hudTipWillShow:YES]; 第四步，上传中，进度提示 if (self.HUD) {

How do I create a HUD on top of my Scenekit.scene

由 青春壹個敷衍的年華 提交于 2020-01-12 07:06:08
问题 I'm experimenting with Swift and Scenekit. Building a Mac OS X app. It seems quite easy to get a 3d-scene working. But what is scene without some kind of 2D hi-score, radar display, speed indicator, etc? I would expect a SpriteKit-scene to seamlessly integrate into a SceneView but I don't find the documentation very clear about this.. The most obvious and only way I can think of is to position a SKView over a SceneView and render each separately. But is there a more elegant way? 回答1: try

HUD玻璃检测工装背景简介

作者: 帅文 背景知识 HUD工作的基本原理就是依靠镜面反射将位于非视线区域的图像反射到视线可视区范围，加上反射区域本身透明的特性最终给用户的感受是图像叠加到前方的景物上。最简单的hud就是你把手机放在汽车前挡下面，手机画面通过前挡玻璃反射进入眼睛就是一个最原始的hud投影原型。如果你仔细观察一下就会发现这个简陋的hud有下面问题：1 不够亮也不够大 2 图像变形 3 投影距离太近 4 有很强的重影 5 投影的位置不理想。这些因素导致你对这种儿童游戏的反射影像方式毫无兴趣。 但是在开车过程中发现下面这些细节有些影响驾乘体验。 1 开车过程中时不时要盯一下车速表 2 导航的时候会频繁的看手机或导航屏幕。 3 有的司机换档的时候还低头看一下档位。 这些短暂的视线脱离驾驶前方会引起短暂的视觉盲区，如果车速快而且脱离时间较长，就像闭着眼睛开车，事故风险急剧增大。另外一个需要考虑的因素就是视线在前方和仪表盘之间来回切换还会导致眼睛需要重新调整焦距（仪表盘距离眼睛一般也就60cm左右，而我们看路面的时候一般都是10m以上的距离），当外界阳光强烈时候我们的瞳孔可能也要不停变换；眼睛的这种频繁切换很容易引起视觉疲劳（你可以自己尝试眼睛交替看近景和远景切换感受一下）。 Hud在利用上面介绍的反射原理来改善驾乘体验为目的下解决上面反射光路提到的问题。 那么如何解决？ 亮度问题：

MBProgressHUD and UITableView

问题 I am displaying a HUD while populating the TableView, but it seems to be showing behind the TableView (tableview separator breaking the hud). Here's the code in the TableViewController: - (void)viewDidLoad { [super viewDidLoad]; MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; hud.mode = MBProgressHUDModeText; hud.labelText = @"Loading"; // Populate the table [self getTableData]; self.tableView.rowHeight = 90; } It's doing this only with TableViews. 回答1: The issue

问题 I'd like to write a simple HUD style application using WPF (if I'm using the wrong technology, I'll take suggestions). As a simple example, I'd to place text along the top of the screen like "Library Computer" that ignores all clicks (ie doesn't effect the rest of Windows) but is always on top and can't be minimized. 回答1: Relevant properties to set on the window: AllowsTranparency -> true WindowStyle -> None ResizeMode -> NoResize WindowState -> Maximized Topmost -> true IsHitTestVisible ->

How to get 2D coordinates on window for 3D object in javafx

由 倖福魔咒の 提交于 2019-12-17 17:13:46
问题 In javafx if we have 2D HUD (made of Pane and then out of it we create SubScene object for 2D Hud) and 3D SubScene and inside 3D scene we have some object with coordinates (x,y,z) - how can we get 2D coordinates in our HUD of the object if it is in visual field of our perspective camera? I tried to get first Scene coordinates of the object and then convert it (sceneToScreen) coordinates and the same for point (0,0) of Pane and then to subtract first point from second point but i don't get

Overlay text on some else's window - HUD

由 时光毁灭记忆、已成空白 提交于 2019-12-14 00:33:58
问题 I am interested in writing an application that overlays a small heads up display (HUD) over another application, in VB.NET. What is an example of this? I will need to enumerate all open windows to find the window that I want, and then overlay some text in a specific position on the window. If the user moves that window, my text will need to follow. (I will probably be painting the text in a loop over and over). Edit: nobody answered my original query - I added C# to the keywords to see if any
