问题 I'm currently using a UITextView in a UITableViewCell in order to make links clickable, but this is giving very poor performance. So I was wondering if it's possible to detect links in a NSString and if there is a link, use the UITextView , otherwise just use a UILabel . 回答1: Absolutely. Use NSDataDetector (NSDataDetector Class Reference) 回答2: I guess you are familiar with regexes to detect URLs, so in order to get one or the other type of view in your cell, you can simply return two

问题 I have a UITableView and a Detail View embedded in a UINavigationController as so: I would like to turn on large titles for "My Notes" but I'd like to turn it off for the detail view. Something like how the default Mail app works on iPhone. How would I change the navigation bar's prefersLargeTitle property during that segue? 回答1: it's very simple. In your DetailView you should set navigationItem.largeTitleDisplayMode to .never (not navigationController?.navigationItem.largeTitleDisplayMode !!

问题 Now I have a range of unicode numbers, I want to show them in UILabel, I can show them if i hardcode them, but that's too slow, so I want to substitute them with a variable, and then change the variable and get the relevant character. For example, now I know the unicode is U+095F, I want to show the range of U+095F to U+096f in UILabel, I can do that with hardcode like NSString *str = [NSString stringWithFormat:@"\u095f"]; but I want to do that like NSInteger hex = 0x095f; [NSString

问题 I have two strings: a variable length piece of text another string with numbers that point to a reference In my view, the first piece of text is displayed in a UILabel, I adjust the size of the label to accomodate the size of the text. This means I cannot just place another UILabel on the screen, at least not without repositioning it...somehow. I need to be able to put the second piece of text so it appears to be at the end of the sentence - and superscripted I really have no idea how to

问题 I have a table view with custom cells and I try to optimize it by making all subviews inside the cells in green color when Color Blended Layer is checked in the simulator. When the background of an UILabel in the cell is set to white: let title = UILabel() contentView.addSubview(title) title.background = UIColor.whiteColor() title.text = "Hi, how are you?" This UILabel subview will become green color in the simulator, which is good. However, if I change the text to some Chinese: title.text =

问题 I'm having some problems implemented dynamic row heights in a UITableView - but it isn't the cells that I'm having a problem with, its the UILabel inside of the cell. The cell just contains a UILabel to display text.

I have a subclass of UITableViewCell that just holds the UILabel property that is hooked up in storyboard. In

问题 I would like to add text, whether it be a UILabel or CATextLayer to a CGPath .

Thanks! Example: 回答1: You'll need to do this by hand, by computing the Bezier function and its slope at each point you care about, and then drawing a glyph at that point and rotation. You'll need to know 4 points
