Method Detail

performEditingTransactionForTextStorageUsingBlock

void performEditingTransactionForTextStorageUsingBlock(NSTextStorage textStorage,
                                                       NSTextStorageObserving.Block_performEditingTransactionForTextStorageUsingBlock transaction)

Transactional editing support

processEditingForTextStorageEditedRangeChangeInLengthInvalidatedRange

void processEditingForTextStorageEditedRangeChangeInLengthInvalidatedRange(NSTextStorage textStorage,
                                                                           long editMask,
                                                                           NSRange newCharRange,
                                                                           long delta,
                                                                           NSRange invalidatedCharRange)

The newCharRange is the range in the final string which was explicitly edited. The invalidatedRange includes portions that changed as a result of attribute fixing. invalidatedRange is either equal to newCharRange or larger. Controllers should not change the contents of the text storage during the execution of this message.

setTextStorage

void setTextStorage(NSTextStorage value)
