可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I've been fiddling in Xcode 4.2 with iOS 5.0's new NSLinguisticTagger. My objective with this function is to take in an address book record and then spit out a composite name as an NSString, sort of like what ABRecordCopyCompositeName does, but taking into account naming order for East Asian languages and Hungarian (last first instead of first last). Here's the function: NSString *text = [self getLocalizedFullNameOfRecord:[contacts objectAtIndex:indexPath.section]; - (NSString *) getLocalizedFullNameOfRecord:(ABRecordRef) person { NSString

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I was wondering if you could help me figure out how to progmatically get the Display Name for a monitor by using its Display ID number in Mac OS X (10.5)? A requirement is if I give a function the Display ID, it'll provide the Display Name in return (or vice versa). Display Name looks something like this: "Color LCD", "SAMSUNG" Display ID looks something like this: "69671872", "893830283" NSScreen in Cocoa (Obj-C), or CGGetActiveDisplayList in Quartz (C), allow you to get the Display ID number for a monitor. Neither appear to have a method

Detecting if an NSString contains…?

半城伤御伤魂 提交于 2019-12-03 00:56:37
问题 How can I detect if a string contains a certain word? For example, I have a string below which reads: @"Here is my string." I'd like to know if I can detect a word in the string, such as "is" for example. 回答1: Here's how I would do it: NSString *someString = @"Here is my string"; NSRange isRange = [someString rangeOfString:@"is " options:NSCaseInsensitiveSearch]; if(isRange.location == 0) { //found it... } else { NSRange isSpacedRange = [someString rangeOfString:@" is " options

Shortcut to generate an NSRange for entire length of NSString?

穿精又带淫゛_ 提交于 2019-12-03 00:54:34
Is there a short way to say "entire string" rather than typing out: NSMakeRange(0, myString.length)] It seems silly that the longest part of this kind of code is the least important (because I usually want to search/replace within entire string)… [myString replaceOccurrencesOfString:@"replace_me" withString:replacementString options:NSCaseInsensitiveSearch range:NSMakeRange(0, myString.length)]; Function? Category method? - (NSRange)fullRange { return (NSRange){0, [self length]}; } [myString replaceOccurrencesOfString:@"replace_me" withString:replacementString options:NSCaseInsensitiveSearch

Objective C - How to concatenate an entire array of strings?

人盡茶涼 提交于 2019-12-03 00:54:12
I am an Objective C newbie. I want to write a method that takes in an array of strings and returns a concatenated string, with a comma (,) in between each string. So if an array is {a b c d}, I want to return a,b,c,d. What is the easiest way to do that? There are many ways to do it, the simplest being [yourArray componentsJoinedByString: @","] Use NSArray's componentsJoinedByString: method. NSArray *strings = ...; NSString *combined = [strings componentsJoinedByString:@","]; 来源: https://stackoverflow.com/questions/7654679/objective-c-how-to-concatenate-an-entire-array-of-strings
