XCode 7 - Misplaced views warning for view in Storyboard

由 孤人 提交于 2019-12-25 16:24:13
问题 I have added a UIView on storyboard in which i set a constraints to top,left,bottom,right as shown below As you can see in the image, orange bordered line indicates that i misplaced the view. My UIView position is 0,20,320,150. I am not sure why xcode shows the warning eventhough i set a correct constraint. I am using Xcode 7 beta version. 回答1: Your constraints doesn't respect you frame. You have frame 0, 20, 320, 150 , but constraints show Trailing Space: -20 and Leading Space: -20 . Set

问题 I was looking at this post. I was wondering if it was possible to make a image swivel in wpf? If not, how would i change the solution to make my WPF image swivel repeatedly? 回答1: I found this simple solution: This is all you need. <pl:Planerator Name="planerator"> <Image Name="logo" Source="somePath" > <Image.Triggers> <EventTrigger RoutedEvent="Image.Loaded"> <BeginStoryboard> <Storyboard TargetProperty="ScaleX" RepeatBehavior="Forever"> <DoubleAnimation Storyboard.TargetName="planerator"

Auto Layout in Navigation Controller with UISegmentedControl: good in iOS7, bad in iOS6

由 左心房为你撑大大i 提交于 2019-12-25 12:09:50
问题 For a navigation controller I like to have a few controls placed in a view from top towards the bottom. I am using auto layout and added constraints, so that the views have a vertical gap to each other. This looks nice for iOS7 and iOS6 in a normal view controller, also for iOS7 in a navigation controller; but wrong in iOS6. The UISegmentedControl shows up wrong. See the screenshots. It looks like the larger height of the UISegmentedControl is not taken into account for iOS6 view. Also it

Storyboard: EventTrigger vs DataTrigger

问题 Storyboards Overview : Animate when a Property Value Changes provides the following description in a attempt to explain the relationship between "EventTrigger and Storyboard", and between "Trigger (i.e., DataTrigger) and Storyboard" but is sounds a bit ambiguous to me and somehow a short description: Animations applied by property Trigger objects behave in a more complex fashion than EventTrigger animations or animations started using Storyboard methods. They "handoff" with animations defined

问题 I have created a container for "modul screens" with UIPageViewController. The main problem is a wrong size if set previous screen. On screenshot you can see that are showed 2 screens instead 1.

when using loadNibNamed why do we have to use 'first'? Don't we want to decouple different entities of our source code? [duplicate]

问题 This question already has answers here : Why “loadNibNamed” methods return array? (3 answers) Closed 2 years ago . For example: NSBundle.mainBundle().loadNibNamed("Games-New", owner: nil, options: nil).first How can there possibly be multiple views?! I only drag one view from the storyboard and then put a label/image inside of it and am done. Or does this mean I can drag multiple container-like views and the first view I drag out would be the first or something? (that would be a pretty bad

Move to another storyboard without a UINavigationController

问题 I've got two storyboards. I found some code on how I can instantiate the initial View Controller of another Storyboard and move (or do you say segue?) to that. But those examples used a Navigation Controller. The user shouldn't be able to go back to the previous Storyboard in my case (login page). The app can forget about the old Storyboard, it's not needed ever again when I move over to the new one. So the View Controller on top of the hierarchy in the first Storybard can be forgotten about,

EventTrigger

由 时间秒杀一切 提交于 2019-12-25 06:53:05
EventTrigger 和 Storyboard 另一种类型的触发器是 EventTrigger ，它根据事件的引发来启动一组操作。 例如，下面的 EventTrigger 对象指定当鼠标指针进入 ListBoxItem 时， MaxHeight 属性在 0.2 秒时间内以动画方式增大为值 90 。 当鼠标离开该项时，该属性在 1 秒时间内还原为原始值。 请注意为何无需为 MouseLeave 动画指定 To 值。 这是因为动画能够跟踪原始值。 <EventTrigger RoutedEvent="Mouse.MouseEnter"> <EventTrigger.Actions> <BeginStoryboard> <Storyboard> <DoubleAnimation Duration="0:0:0.2" Storyboard.TargetProperty="MaxHeight" To="90" /> </Storyboard> </BeginStoryboard> </EventTrigger.Actions> </EventTrigger> <EventTrigger RoutedEvent="Mouse.MouseLeave"> <EventTrigger.Actions> <BeginStoryboard> <Storyboard> <DoubleAnimation

问题 I have a UITableView and I had like to download images asynchronously. How can I do using using ios5 and storyboards? Thanks in advance 回答1: I was having the very same problem, and what I did was take SDWebImage from https://github.com/rs/SDWebImage, open up the project on its own, and manually upgrade it to Objective C ARC (Refactor --> Convert to Objective C ARC). When it was done being converted, I added it the individual files to my project and it works like a charm. I just #import
