iOS: UILabel dynamic height using sizeWithFont:constrainedToSize:lineBreakMode: not working

由 我的梦境 提交于 2019-12-09 13:24:39
问题 I am trying to give my UILabel dynamic height so that my layout of other labels looks correct in both landscape and portrait. In portrait, my text wraps to the second line, in landscape it does not. So, when using sizeWithFont:constrainedToSize:lineBreakMode: I get the same height when rotating both ways, when I had assumed it would be a larger number when the text was 2 lines. How can I get the height of my UILabel when it has two lines of text or more (portrait) and get the new height which

Centering a label in a UIView

由 ⅰ亾dé卋堺 提交于 2019-12-09 11:36:44
问题 What's the best way to center a label in a UIView ? If you do something such as UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(view.frame.origin.x / 2, view.frame.origin.y / 2, 50.0, 50.0)]; Then you're setting the origin point of the label to the center of the view. The best bet would be to set the center of the view to that point using the center property. So I tried using the following code: UIView *aView = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen]

由 白昼怎懂夜的黑 提交于 2019-12-09 04:30:32
问题 I created a grid of buttons. The following code creates the buttons and displays them, but there is no text on the button. Is there a setting I am missing? (Obj-C replies are fine, I'm bi-lingual) RectangleF frame = new RectangleF (X + 3, Y + 3, cellWidth - 2, cellHeight - 2); UIButton button = new UIButton (frame); button.TitleLabel.Text = "Baha'i"; button.TitleLabel.Font = UIFont.FromName ("Helvetica-Bold", 15); button.TitleLabel.TextColor = UIColor.Black; button.TitleLabel.Frame = frame;

UITableViewCell color issues with custom table view background

由 做~自己de王妃 提交于 2019-12-08 21:47:42
问题 I have a UITableView with a custom background image set like this: self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"mybg.png"]]; The background appears fine, but my UITableViewCells (default cells, not custom) have some sort of weird tint to them, and the UILabel containing the "New Project" text also seems to have some sort of background behind it. How can I remove this? I've already tried: cell.backgroundColor = [UIColor clearColor]; cell.textLabel

问题 Assigning large string to UILabel. And, adding this label into a scroll view. The UILabel disappear when the UILabel height larger than 8192pt (which is 2^13). Is this an iOS bug?

UPDATE The code that will display the UILabel: UILabel *label = [[UILabel alloc] init]; label.backgroundColor = [UIColor clearColor]; label.text = rumor.displayText; label.frame = CGRectMake(0, 0, self.view

-setCornerRadius not found in custom view

由 て烟熏妆下的殇ゞ 提交于 2019-12-08 16:47:32
问题 I am making a custom uitableviewcell class and inside this cell I have a square label. I would like to round the corners of the label(dateBox) using this: [dateBox.layer setCornerRadius:4.0f]; [dateBox.layer setMasksToBounds:YES]; I do this is other classes and it works fine, but for some reason in the uitableviewcell subclass, I get the warning "setCornerRadius method not found". Does anyone know why this might be? 回答1: You need to import QuartzCore and make sure it is an included framework

IOS - Justify UILabel like in the newspaper

由 自作多情 提交于 2019-12-08 14:36:24
I'm trying to align my UILabel/UITextView like in the picture below. Anyone got a lead how to justify the text that way. I have some trouble with NSTextAlignementJustified too. You can achieve this with the use of NSAttributedString, by setting the alignment and by setting firstLineHeadIndent to something close to zero (why? hmmmm... well I don't know): NSMutableParagraphStyle *paragraphStyles = [[NSMutableParagraphStyle alloc] init]; paragraphStyles.alignment = NSTextAlignmentJustified; paragraphStyles.firstLineHeadIndent = 0.001f; NSString *stringTojustify = @"Lorem ipsum dolor sit amet,

NSBackgroundColorAttributeName for multiline attributed strings labels

由 这一生的挚爱 提交于 2019-12-08 13:48:27
问题 I'm trying to display a map with information overlayed. To improve legibility on the map, I tried several ways (text shadows, outline text, darkening the map), but nothing really worked well – hence I tried to use a semitransparent box underneath the text. I'm using the NSBackgroundColorAttributeName , which – as you can see in the screenshot – works fine for single line labels. In the multiline case though, the box seems to fill a whole line, even if there are no characters above. Is this a
