nsrange

In my application I have some code to fetch the range of the host in a URL . It looks like this: private func rangeOfHost(text: String) -> NSRange? { let url = URL(string: text) if let host: String = url?.host { if let range = text.range(of: host) { return NSRange(location: range.lowerBound.encodedOffset, length: range.upperBound.encodedOffset - range.lowerBound.encodedOffset) } } return nil } Xcode has been warning me that 'encodedOffset' is deprecated: encodedOffset has been deprecated as most common usage is incorrect. Use utf16Offset(in:) to achieve the same behavior. . However, it's not

I am accepting an NSString of random size from a UITextField and passing it over to a method that I am creating that will capture only the last 4 characters entered in the string . I have looked through NSString Class Reference library and the only real option I have found that looks like it will do what I want it to is - (void)getCharacters:(unichar *)buffer range:(NSRange)aRange I have used this once before but with static parameters 'that do not change', But for this implementation I am wanting to use non static parameters that change depending on the size of the string coming in. So far

I have a UILabel I've made programmatically as: var label = UILabel() I've then declared some styling for the label, including a font, such as: label.frame = CGRect(x: 20, y: myHeaderView.frame.height / 2, width: 300, height: 30) label.font = UIFont(name: "Typo GeoSlab Regular Demo", size: 15) label.textColor = UIColor(hue: 0/360, saturation: 0/100, brightness: 91/100, alpha: 1) The first part of the label will always read : "Filter:" then followed by another part of the string, for example, "Most popular" I would like the word filter to be in bold, so the whole thing would look like: Filter:

I'm trying to add some fancy text to a label, but I've run into some problems with the NSMutableAttributedString class. I was trying to achieve four this: 1. Change font, 2. Underline range, 3. Change range color, 4. Superscript range. This code: - (void)applicationDidFinishLaunching:(NSNotification*)aNotification { NSMutableAttributedString* display = [[NSMutableAttributedString alloc] initWithString:@"Hello world!"]; NSUInteger length = [[display string]length] - 1; NSRange wholeRange = NSMakeRange(0, length); NSRange helloRange = NSMakeRange(0, 4); NSRange worldRange = NSMakeRange(6, length

I have two NSStrings: orgText and searchLetter . I want to highlight every occurrences of the searchLetter in the orgText with a red color. How can I get the NSRange of all occurrences of the searchLetter ? for eg : suppose: orgText = "abcahaiapaoiuiapplma" searchLetter = "a". I want to hightlight all "a" occurrences in "abcahaiapaoiuiapplma" with red color. Thanks. I wrote this method for my project - SUITextView with highlight : - (NSMutableAttributedString*) setColor:(UIColor*)color word:(NSString*)word inText:(NSMutableAttributedString*)mutableAttributedString { NSUInteger count = 0,

I'm trying to use NSRange to hold a range of years, such as NSRange years = NSMakeRange(2011, 5); I know NSRange is used mostly for filtering, however I want to loop over the elements in the range. Is that possible without converting the NSRange into a NSArray ? It kind of sounds like you're expecting NSRange to be like a Python range object. It's not; NSRange is simply a struct typedef struct _NSRange { NSUInteger location; NSUInteger length; } NSRange; not an object. Once you've created one, you can use its members in a plain old for loop: NSUInteger year; for(year = years.location; year <
