问题 Here's the code I'm using, it prints nothing no matter what sentence I use on the device. On simulator it works fine! - (NSMutableArray *)getTagEntries:(NSString *)sentence { NSArray<NSLinguisticTagScheme> *tagSchemes = [NSLinguisticTagger availableTagSchemesForLanguage:@"en"]; NSLinguisticTaggerOptions options = NSLinguisticTaggerJoinNames | NSLinguisticTaggerOmitWhitespace; NSLinguisticTagger *linguisticTagger = [[NSLinguisticTagger alloc] initWithTagSchemes:tagSchemes options:options];

问题 Does anyone understand why this is happening? On any simulator all of the schemes are found with the following code: NSArray<NSLinguisticTagScheme> *availSchemes = [NSLinguisticTagger availableTagSchemesForLanguage:@"en"]; for (NSLinguisticTagScheme scheme in availSchemes) { NSLog(@"Tag scheme %@", scheme); } yielding the following: 2018-02-13 09:12:54.066970-0500 MY_APP[79671:5737063] Tag scheme Language 2018-02-13 09:12:54.067160-0500 MY_APP[79671:5737063] Tag scheme Script 2018-02-13 09:12

阅读更多关于 How to detect text (string) language in iOS?

问题 For instance, given the following strings: let textEN = "The quick brown fox jumps over the lazy dog" let textES = "El zorro marrón rápido salta sobre el perro perezoso" let textAR = "الثعلب البني السريع يقفز فوق الكلب الكسول" let textDE = "Der schnelle braune Fuchs springt über den faulen Hund" I want to detect the used language in each of them. Let's assume the signature for the implemented function is: func detectedLangauge<T: StringProtocol>(_ forString: T) -> String? returns an Optional

问题 I need to match a keyword (which is in its lexical form) with a text and return whether the keyword matches (just like a search engine) for example text: I want some apples keyword: apple result: matched keyword: banana result: not matched This is my method, I always get null for the tag - (BOOL)matchKeywordWithText:(NSString *)text keyword:(NSString *)keyword { __block NSMutableArray *words = [NSMutableArray array]; NSLinguisticTaggerOptions options = NSLinguisticTaggerOmitWhitespace |

Converting a Vision VNTextObservation to a String

阅读更多关于 Converting a Vision VNTextObservation to a String

I'm looking through the Apple's Vision API documentation and I see a couple of classes that relate to text detection in UIImages : 1) class VNDetectTextRectanglesRequest 2) class VNTextObservation It looks like they can detect characters, but I don't see a means to do anything with the characters. Once you've got characters detected, how would you go about turning them into something that can be interpreted by NSLinguisticTagger ? Here's a post that is a brief overview of Vision . Thank you for reading. SwiftOCR I just got SwiftOCR to work with small sets of text. https://github.com/garnele007
