detectPatterns(for:completionHandler:)
Determines whether the first pasteboard item matches the specified patterns, without notifying the user.
Declaration
func detectPatterns(for patterns: Set<UIPasteboard.DetectionPattern>, completionHandler: @escaping (Result<Set<UIPasteboard.DetectionPattern>, any Error>) -> ())Parameters
- patterns:
The patterns to detect on the pasteboard.
- completionHandler:
A closure that the system invokes after detecting patterns on the pasteboard. The closure receives a
Resultinstance that contains either a set with the patterns found on the pasteboard or an error if detection failed.
Discussion
Because this method only gives an indication of whether a pasteboard item matches a particular pattern and doesn’t allow the app to access the contents, the system doesn’t notify the user about reading the contents of the pasteboard.
