问题 I am trying to do a RoutedEvent to activate ColorAnimation over a TextBlock and a Panel inside Buttons . My goal is to change the TextBlock's Foreground and the Panel's Background when using the MouseEnter and MouseLeave RoutedEvents. The below code is actually working. But it works only when the mouse cursor is over one of these two objects (which makes sense).

问题 Can a viewcontroller access the identifier of the segue that was used to transition to it? For example, I transition from viewcontroller A to viewcontroller B using a segue with the identifier "mySegue". Is there anyway for viewcontroller B to get the segue's identifier? 回答1: I don't believe there is such a property. This kind of thing should be handled via the calling VC's prepareForSegue:sender method (as said in the comments) and then assigning a custom property to denote where it came

问题 I'm trying to edit the tile of the back item in the navigation controller. I have this scene, Navigation Controller -> Table View Controller -> TableViewController . In the second TableViewController I want to rename the the back item from " xxxx " to " Back ". Is there a way to do via the StoryBoard , or should I do it programmatically ?

问题 All of the sudden my .storyboard file for my project only is shown in XML. I am well aware of the "right click" -> "Open As" -> "Storyboard" option, however this does not appear. It only displays "None". How do I fix this so I can open my storyboard as an actual storyboard? 回答1: I suspect you are looking at Xcodes "Version Editor". Double check that you are not.

问题 I use a data trigger to control some storyboards, but it only can be trigger one time. <Style x:Key="PropertyTriggerExampleButtonStyle" TargetType="{x:Type Button}"> <Setter Property="Width" Value="200" /> <Style.Triggers> <DataTrigger Binding="{Binding para}" Value="0"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty="Width" To="500" Duration="0:0:1" /> </Storyboard> </BeginStoryboard> </DataTrigger.EnterActions> </DataTrigger>

问题 Xcode can't find my Storyboards and my Info.plist in my Copy Bundle Resources , So my App doesn't run. I tried to add the Existing files again but they always appear red highlighted. I'm pretty sure it must be a local problem because when i clone the latest update from my repository on my other mac its runs without any problems. I already tried to re-install Xcode, delete files from Xcode/DerivedData and i also deleted the com.apple.Xcode.plist . Anyone any ideas? 回答1: Try to reset your

问题 Is there any way to find which UI element an IBOutlet declared in code is connected to? 回答1: Go to your view controller file where you have declared IBOutlet (.h or .m). Then you can see left side of each variable declaration there is a dark grey round image. (It is filled if you have connected that IBOutlet with Storyboard/Xib unless it is unfilled.) By clicking that image you can see small popover which shows connection of outlet. See below image will show you. 来源： https://stackoverflow.com

问题 Activity indicator in launch screen doesn't animate. How to make it work? I can't do startAnimating() because cannot assign class to launch screen. The checkbox in the attribute inspector does't work as well. 回答1: The launch screen is not a splash screen. It is, in effect, just a picture, hiding the gap between the time the user summons your app and the time your app runs. You cannot do anything in the launch screen because, by definition, if the launch screen is visible your app is not yet
