问题 I followed the steps outlined in various locations using the UIAppFonts property list key. I'm using the Aller Light font. I've added it as a resource, added the font name correctly in the info property list, and am now attempting to use it, however every attempt to do so results in the default font being displayed. So far I've tried: [leader setFont:[UIFont fontWithName:@"Aller Light" size:20.0]]; [leader setFont:[UIFont fontWithName:@"AllerLight" size:20.0]]; [leader setFont:[UIFont

问题 I have tried so many tutorials that I am wondering why I am not getting such a simple problem. I have a view controller called SetBudgetViewController. I have a text field in this view that I have connected as an outlet called *amountToSpend. I have another view used elsewhere in the app that has a label called *amountSet. How do I make the numbers entered into the first text field be displayed in the label in the other view? Thank you all so much (this is driving me mad)! 回答1: First, declare

问题 I have a customized UITableViewCell that has an image on the left and two UILabels on the right. The top edge of the first label is horizontally aligned with the top of the image, and the second label has its bottom edge aligned with the bottom of the image. The second label displays a larger content and I'm hoping that it could resize vertically to show more content but it should not interfere with the top label(for which I've set a vertical spacing constraint between the top label and the

问题 I already have a slider that controls the output of a text label. -(IBAction)mySlider:(UISlider *)sender { _myTextLabel.text = [NSString stringWithFormat:@"%i", (int) sender.value]; } However, I also want a stepper to be able to changer the slider's position. So, if the slider has been set to 50, and the text label says 50, I want the stepper to increment to 51, 52, 53, etc. Does anyone know the code to do this? Thanks! 回答1: You will need to keep an reference for the UISlider . Make a handler

问题 I need to get a UILabel to go to more than one line if text requires with autolayout. In code and also in storyboard for good measure I have set numberOfLines to 0 and wordwrapping on and I've also called sizeToFit . The full amount of text will display on multiple lines if I set the height constraint for the label to a large enough value such = 200. But with short text, it does not contract, leaving a lot of white space. But if I set the height constraint to a lower value such as >=21 then

问题 I have 3 UILabels drawn in storyboard positioned on top of each other. Static UI Label 1 Dynamic UI Label 2 Static UI Label 3 Labels 1 and 3 are static and never change. Label 2 is dynamic and is always one sentence long, but could be a short or long sentence that wraps. I want Label 2 to be perfectly vertically centered between label 1 and label 3 based on how much text is there. Any ideas how to do this? Greatly appreciated! 回答1: If you're using auto layout (which is on by default), then

问题 I have a UITableViewCell with two UILabel s: title and description. I am having problems with the title label. Basically, what I want is to increase its height if the text is bigger than the available space and prevent the "...". This is how it looks, you can see the constraints of the title label on the right. As you can see, the title label successfully increase its height but the text still in one line.

问题 I have been looking for any example code for drawing a UILabel (or just an NSString or something) on a curved path, but have come up empty handed. Does anyone know whether it's possible to draw text on a curved path, like a circle or something, without using separate pieces of graphics for every single letter? 回答1: Split the String into letters and then so something like this: How do I draw an NSString at an angle? increasing the angle and changing the position after every letter. 来源： https:/
