NSString is really a container class for different types of string objects. Generally an NSString constructor does return an object that is actually of type NSCFString, which is a thin wrapper around the Core Foundation CFString struct.
NSString* finish = [[start componentsSeparatedByCharactersInSet:[[NSCharacterSet letterCharacterSet] invertedSet]] componentsJoinedByString:@””];
We can do this by splitting and then joining. Requires OS X 10.5+ for the componentsSeparatedByCharactersInSet: NSCharacterSet *charactersToRemove = [[NSCharacterSet alphanumericCharacterSet] invertedSet]; NSString *strippedReplacement = [[someString componentsSeparatedByCharactersInSet:charactersToRemove] componentsJoinedByString:@””];
How about create new label and using sizeThatFit:(CGSize)size ?? UILabel *gettingSizeLabel = [[UILabel alloc] init]; gettingSizeLabel.font = [UIFont fontWithName:@”YOUR FONT’s NAME” size:16]; gettingSizeLabel.text = @”YOUR LABEL’s TEXT”; gettingSizeLabel.numberOfLines = 0; gettingSizeLabel.lineBreakMode = NSLineBreakByWordWrapping; CGSize maximumLabelSize = CGSizeMake(310, CGFLOAT_MAX); CGSize expectSize = [gettingSizeLabel sizeThatFits:maximumLabelSize]; Edit: This upper code is not good for ios 7 and above, … Read more
I believe you are misinterpreting the JSON format for key values. You should store your string as NSString *jsonString = @”{\”ID\”:{\”Content\”:268,\”type\”:\”text\”},\”ContractTemplateID\”:{\”Content\”:65,\”type\”:\”text\”}}”; NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil]; Now if you do following NSLog statement NSLog(@”%@”,[json objectForKey:@”ID”]); Result would be another NSDictionary. { Content = 268; type = text; }
You need to escape the non-ASCII characters in your hardcoded URL as well: //localisationName is a arbitrary string here NSString* webName = [localisationName stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString* stringURL = [NSString stringWithFormat:@”http://maps.google.com/maps/geo?q=%@,Montréal,Communauté-Urbaine-de-Montréal,Québec,Canadae&output=csv&oe=utf8&sensor=false”, webName]; NSString* webStringURL = [stringURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSURL* url = [NSURL URLWithString:webStringURL]; You can probably remove the escaping of the localisationName since it will be handled by … Read more
I think this could help you: import Foundation let timeNow = time(nil) let aStr = String(format: “%@%x”, “timeNow in hex: “, timeNow) print(aStr) Example result: timeNow in hex: 5cdc9c8d
You can use libxml2. I suspect it is the fastest approach. Add its framework to your project (see the “setting up your project” section of this document). In the header of your XML writer, add the following imports: #import <libxml/encoding.h> #import <libxml/xmlwriter.h> In the implementation, write a method to generate your XML. Presumably you’ll be … Read more
Example: CGFloat maxWidth = 150; NSAttributedString *s = [[NSAttributedString alloc] initWithString:@”The quick brown fox jumped over the lazy dog.” attributes:@{NSFontAttributeName:[UIFont fontWithName:@”GillSans” size:20]}]; NSTextContainer* tc = [[NSTextContainer alloc] initWithSize:CGSizeMake(maxWidth,CGFLOAT_MAX)]; NSLayoutManager* lm = [NSLayoutManager new]; NSTextStorage* tm = [[NSTextStorage alloc] initWithAttributedString:s]; [tm addLayoutManager:lm]; [lm addTextContainer:tc]; [lm enumerateLineFragmentsForGlyphRange:NSMakeRange(0,lm.numberOfGlyphs) usingBlock:^(CGRect rect, CGRect usedRect, NSTextContainer *textContainer, NSRange glyphRange, BOOL *stop) … Read more
Yes, CoreText is the best way to do this. The code to do it is a little long to post here. Some code that may point you in the right direction is in the article “Clipping a CGRect to a CGPath.” If the process for doing it is still confusing, ping me and I finally … Read more
