我試圖在我的應用程序中實現一個共享按鈕,所以很自然地,我轉向UIActivityViewController
。出於某種原因,任何時候我按下分享按鈕,它會彈出,我得到了我的日誌中看到以下消息:爲什麼ActivityViewController在控制檯中顯示自動約束錯誤?
Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
(
"<NSLayoutConstraint:0x7c0a65d0 V:[UIView:0x7c0a2fa0(<=528)]>",
"<NSLayoutConstraint:0x7c0a6540 UIView:0x7c0a2fa0.height == UIView:0x7c0a2e60.height>",
"<NSLayoutConstraint:0x7c0a7100 _UIAlertControllerView:0x7c0a27f0.height == UIView:0x7c0a2e60.height>",
"<NSLayoutConstraint:0x7c0b1660 V:[_UIAlertControllerView:0x7c0a27f0(568)]>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x7c0a65d0 V:[UIView:0x7c0a2fa0(<=528)]>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

調用它時我沒有做任何幻想,只是最低限度:
let someText:String = "Hello"
let activityViewController = UIActivityViewController(activityItems: [someText], applicationActivities: nil)
activityViewController.excludedActivityTypes = [
UIActivityTypePostToWeibo,
UIActivityTypePrint,
UIActivityTypeCopyToPasteboard,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo,
UIActivityTypePostToTencentWeibo
] self.navigationController!.presentViewController(activityViewController,
animated: true,
completion: nil)
這會是從Xcode中的β7/9的iOS錯誤?或者我錯過了什麼?我應該擔心嗎?
我得到相同的錯誤Xcode中的β7/9的iOS我 –
