I'm initializing a scrollview here: ScrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(0,0,320,480)]; ScrollView.showsVerticalScrollIndicator=YES; ScrollView.scrollEnabled=YES; ScrollView.bounces = YES; ScrollView.userInteractionEnabled=YES; [self.view addSubview:ScrollView]; ScrollView.contentSize = CGSizeMake(10500,480); [self.view addSubview:homeButton]; I have arrays

问题 I use NSLog(@"%@"); And the NSLog result is '23204239423' I don't explain you why ... it's just an example. I want the NSLog result appear in UILabel, is it possible ? I tried : Label.text = (@"%@"); , it doesn't work. Do you know how i can do it ? Thanks. 回答1: NSLog usually takes a string like: NSLog(@"%@", string); So instead just do this: label.text = [NSString stringWithFormat:@"%@", string]; 回答2: You have to put a variable NSString *text = @"My Text"; label.text = text; Or label.text = @

问题 I have a problem with adding Read More/Less text in paragraph. That text needs in iPod but no need for iPad. Please view the attached image below.

问题 I have written a simple Xcode project in swift for my iPhone . I am trying to send the text of my label to facebook using facebook share option . Below is my code import UIKit import Social class ViewController: UIViewController { @IBOutlet weak var musicDescription: UILabel! override func viewDidLoad() { super.viewDidLoad() } @IBAction func faceBookShareButton(sender: UIButton) { if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) { let fbShare:SLComposeViewController

问题 I have a UILabel (named contentLbl) that will change dynamically within a UIScrollView. Above it is another UILabel (named contentTitleLbl) that is a title and does not contain dynamic content. To successfully scroll I know that I must at least set the ContentSize of the UIScrollView to that of the content view's. I've also seen that the Frame should be set. I have tried both but it still does not scroll. In my example code contentView contains both the contentLbl and contentTitleLbl.

问题 I've got a UILabel and a UITextField. Each time the user enters text in the field, I need to check weather the textfield text exists in the label's text (basically I'm searching the label's text) . I was using NSRange range = [sentenceRequestLabel.text rangeOfString:resultString]; if (range.location == NSNotFound) { NSLog(@"string was found"); } else { NSLog(@"string was not found"); } to check (resultString being the textfield.text), but even if the label text in the text field is not even

问题 Our requirement is to show some text bold and some text as normal style in a label. e.g. ABC 002 (there is not space between ABC and 002) There are lots of instances of such labels on a single view, so using UIWebView is not preferred. Is it possible using the UILabel? If no, then what are the alternatives? 回答1: Using normal UILabel dont think this is possible. Check out this replacement for UILabel TTTAttributedLabel. Another way is to use a CATextLayer with an NSAttributedString ! much

问题 I am trying to manipulate the text the user copied from a UILabel into the UIPasteboard but can't find an example. 回答1: Here is a full sample view controller for what you are trying to achieve (read the comments to understand what is going on...): import UIKit import MobileCoreServices class ViewController: UIViewController { override func viewWillAppear(animated: Bool) { super.viewWillAppear(animated) // add an observer (self) for whenever the pasteboard contents change // this is going to
