Apple’s documentation

Provided Methods

fn selectedTextRange(&self) -> Option<Retained<UITextRange>>

where Self: Sized + Message,

Available on crate feature UITextInput only.

Overlap from UITextInput: Returns the currently selected text range, if applicable. Nil otherwise.

unsafe fn compareFoundRange_toRange_inDocument( &self, found_range: &UITextRange, to_range: &UITextRange, document: Option<&UITextSearchDocumentIdentifier>, ) -> NSComparisonResult

where Self: Sized + Message,

Available on crate feature UITextInput only.

Provide a comparison result comparing developer-provided fromRangeto toRange. This is used by the system find panel to know which UITextRangeto highlight next when the user taps the “next” or “previous” result buttons.

Parameter foundRange: Developer-provided range to compare from.

Parameter toRange: Developer-provided range to compare to.

Parameter document: If multiple documents are used, a document identifier will be provided here. Ranges are only compared between other ranges of the same document.

Safety

document should be of the correct type.

fn performTextSearchWithQueryString_usingOptions_resultAggregator( &self, string: &NSString, options: &UITextSearchOptions, aggregator: &ProtocolObject<dyn UITextSearchAggregator>, )

where Self: Sized + Message,

Available on crate feature UIFindSession only.

Perform a text search (across all available searchable documents) using string.When results are found, provide the results to aggregator.

Parameter string: The query string to search for

Parameter options: Search options provided by the user.

Parameter aggregator: When results are found, provide them to the aggregator. The aggregator is thread-safe, so you may send it messages on other threads.

unsafe fn decorateFoundTextRange_inDocument_usingStyle( &self, range: &UITextRange, document: Option<&UITextSearchDocumentIdentifier>, style: UITextSearchFoundTextStyle, )

where Self: Sized + Message,

Available on crate feature UITextInput only.

Given a found range, decorate this text appropriately using the provided styletype.

Parameter range: The range of text to decorate.

Parameter document: If multiple documents are used, the relevant document identifier is provided here. Otherwise nil.

Parameter style: A style hint for how to decorate the text. This is ultimately up to the developer, but developers are encouraged to match the system’s appearance (i.e., UITextView) as close as possible.

Safety

document should be of the correct type.

fn clearAllDecoratedFoundText(&self)

where Self: Sized + Message,

Called when the current search session has changed or ended, with the expectation that all decorations applied via decorateFoundTextRange:usingStyle:are cleared.

fn supportsTextReplacement(&self) -> bool

where Self: Sized + Message,

Return YES if your searchable item also supports replacement. If this method is unimplemented, it is assumed that text replacement is not supported.

unsafe fn shouldReplaceFoundTextInRange_inDocument_withText( &self, range: &UITextRange, document: Option<&UITextSearchDocumentIdentifier>, replacement_text: &NSString, ) -> bool

where Self: Sized + Message,

Available on crate feature UITextInput only.

Optionally return NO to disallow the replacement of a particular result range. This will disable the “replace” button in the UI. If this method is unimplemented, it is assumed that all results are replaceable.

Parameter range: Range to replace.

Parameter document: If multiple documents are used, the document from which range originates.

Parameter replacementText: Text that the user intends to replace with.

Safety

document should be of the correct type.

unsafe fn replaceFoundTextInRange_inDocument_withText( &self, range: &UITextRange, document: Option<&UITextSearchDocumentIdentifier>, replacement_text: &NSString, )

where Self: Sized + Message,

Available on crate feature UITextInput only.

If you return YES for -supportsTextReplacement, this method will be called whenever the user intends to replace a range of text.

Parameter range: The range of text requesting to be replaced.

Parameter document: If multiple search documents are used, the relevant document identifier is provided here. Otherwise nil.

Parameter replacementText: The replacement string.

Safety

document should be of the correct type.

fn replaceAllOccurrencesOfQueryString_usingOptions_withText( &self, query_string: &NSString, options: &UITextSearchOptions, replacement_text: &NSString, )

where Self: Sized + Message,

Available on crate feature UIFindSession only.

When replacing all occurrences at once, this method is called instead of the one above.

Parameter queryString: The search term to replace.

Parameter options: Search options provided by the find panel UI.

Parameter replacementText: The string to replace it with.

unsafe fn willHighlightFoundTextRange_inDocument( &self, range: &UITextRange, document: Option<&UITextSearchDocumentIdentifier>, )

where Self: Sized + Message,

Available on crate feature UITextInput only.

Called when the highlighted search result is about to change to range.

Safety

document should be of the correct type.

unsafe fn scrollRangeToVisible_inDocument( &self, range: &UITextRange, document: Option<&UITextSearchDocumentIdentifier>, )

where Self: Sized + Message,

Available on crate feature UITextInput only.

If scrolling is supported, implement this to know when the document should be scrolled to a particular search result.

Parameter range: The text range to scroll to.

Parameter document: (Optional) If multiple documents are used, the document identifier to scroll to.

Safety

document should be of the correct type.

fn selectedTextSearchDocument( &self, ) -> Option<Retained<UITextSearchDocumentIdentifier>>

where Self: Sized + Message,

Returns the current search document, if applicable. Nil otherwise.

unsafe fn compareOrderFromDocument_toDocument( &self, from_document: &UITextSearchDocumentIdentifier, to_document: &UITextSearchDocumentIdentifier, ) -> NSComparisonResult

where Self: Sized + Message,

Returns the visible ordering from fromDocument to toDocument. If your document identifiers are index paths, for example, this would yield the same result as -[NSIndexPath compare:].

Safety

• from_document should be of the correct type.
• to_document should be of the correct type.
