问题 I have looked into this, but I’m still not quite clear how to do it. I have a UILabel. I would like to write out a word... letter by latter. It goes through each letter, then at the end the entire word shows up. At first I thought it was just because it was too fast, so I put in a delay with something like this. typedWord.text = [typedWord.text stringByAppendingString:@"C"]; future = [NSDate dateWithTimeIntervalSinceNow: letterPause ]; [NSThread sleepUntilDate:future]; Then I read that it may

How to bind value of UILabel to an instance variable?

问题 I am a complete newbie to mac/objective-c. My question is: I wonder if it's possible to bind a UILabel text to a variable, while not having to manually set the text when value change. For example, on Mac OS, when I open a new Finder window and delete a file, then the global free space in the taskbar is changing. And that value also change in all the "finder" that are open. How can I replicate such behavior using Objective-c, either on Mac or for iPhone ? I was thinking about UILabel, but I

问题 I have an NSString that then sets a UILabel. This contains unicode such as... E = MC Hammer\U00ac\U2264 and complete ones such as \U2013\U00ee\U2013\U00e6\U2013\U2202\U2013\U220f\U2013\U03c0 \U2013\U00ee\U2013\U220f\U2013\U03c0\U2013\U00aa\U2013\U221e\U2014\U00c5 These are not displaying correctly, is there anything I need to do to parse these at all? 回答1: "U" needs to be a lowercase "u" 回答2: What code are you using to set the NSString ?

Programmatically perform an action on UILabel touchUpInside?

阅读更多关于 Programmatically perform an action on UILabel touchUpInside?

问题 I have a bunch of UILabels that I add through code and I want to perform a specific action for each if the user's finger touches up inside (much like UIButton's touchUpInside in IB). What is the best way of doing this? 回答1: The easiest way is probably to use UIButton instead of UILabel. A custom UIButton has no border and can look like a plain label, but handles the event tracking for you. Otherwise, you must derive from UILabel and implement the UIResponder calls for touch handling. 回答2: You
