nsstring

I am trying to remove all of the non-numeric characters from an NSString , but I also need to keep the spaces. Here is what I have been using. NSString *strippedBbox = [_bbox stringByReplacingOccurrencesOfString:@"[^0-9]" withString:@"" options:NSRegularExpressionSearch range:NSMakeRange(0, [_bbox length])]; If I give it a NSString of Test 333 9599 999 It will return 3339599999 but I need to keep the spaces in. How can I do this? Easily done by creating a character set of characters you want to keep and using invertedSet to create an "all others" set. Then split the string into an array

What's the best way to get an url minus its query string in Objective-C? An example: Input: http://www.example.com/folder/page.htm?param1=value1&param2=value2 Output: http://www.example.com/folder/page.htm Is there a NSURL method to do this that I'm missing? There's no NSURL method I can see. You might try something like: NSURL *newURL = [[NSURL alloc] initWithScheme:[url scheme] host:[url host] path:[url path]]; Testing looks good: #import <Foundation/Foundation.h> int main(int argc, char *argv[]) { NSAutoreleasePool *arp = [[NSAutoreleasePool alloc] init]; NSURL *url = [NSURL URLWithString:@

I am new to iPhone development. I am creating an application in which i need to create buttons and labels programmatically.

I'm diving into iOS development and the Objective C language and am building an alarm clock app to become familiar with the SDK and language. I have an NSString object that represents a time, with the range "1:00 am" to "12:59 am" . I need to convert this NSString into two NSInteger 's that contain the hour value and minute value. As I'm doing this, I'm finding the NSString manipulation that I'm doing to be extremely laborious and it just feels like sloppy code. Is there a simple way to extract the hour and minute characters from a NSString representation of a time value and store their

I'm using stringWithFormat @"%ls" to do it and I only see the first character copied, which makes me think it's still assuming it's a single byte char. Any ideas? Use initWithBytes:length:encoding . You will have to know the encoding that wchar_t uses, I believe it is UTF-32 on Apple platforms. #if defined(__BIG_ENDIAN__) # define WCHAR_ENCODING NSUTF32BigEndianStringEncoding #elif defined(__LITTLE_ENDIAN__) # define WCHAR_ENCODING NSUTF32LittleEndianStringEncoding #endif [[NSString alloc] initWithBytes:mystring length:(mylength * 4) encoding:WCHAR_ENCODING] In general, I suggest avoid using

How can i encode my NSString so all the special character for example & becomes &amp and ' becomes &apos? I am not sure if encoding is the right word for it so please correct me if I am wrong. Thanks Regexident What you are talking about is called HTML Entities . There exists a category claiming to solve this: NSString+HTML . For URL Escaping (while we're at it) use this: @nterface NSString (Escaping) - (NSString *)percentEscapedString - (NSString *)percentUnescapedString @end @implementation NSString (Escaping) - (NSString *)percentEscapedString { return [self
