I'm struggling with a problem. Some labels are not being calculated correctly in my list.
As you can see in the image below, when the text is too large an ellipsis is added to the end of the label and there is an extra space on the top and bottom of the label. But when the text has only 3 lines, the label size hugs the text properly.
Anyone knows how to fix this?

I need to fit a label and an image in a table view cell in such a way that the image should be placed immediately next to the label but within the cell visibility. ie., they should look like below,
When the text is smaller or within a line, then the image could be immediate next to the label. Eg -
Smaller text (image)
When the text goes beyond a line, then image could be at the edge of the cell because the label length had already been extended to the length. Eg -
Multiline text multi-line text multi-line
text multi-line text multi-line text multi (image)
multi-line text multi-line text
I am trying to achieve this using VFL and no storyboard or nib.
What I tried out :
1. "H:|-[label]-[image(==20)]-|" , "V:|-[label]-|"
This makes the image to always attached to the edge thus the case 1 fails which needs the image near the label. Eg -
case 1 :
Smaller text (image) (not ok)
case 2 :
Multiline text multi-line text multi-line
text multi-line text multi-line text multi (image) (ok)
multi-line text multi-line text
2. "H:|-[label]-[image(==20)]" , "V:|-[label]-|"
This makes the image near the text thus okay for case 1 whereas that fails for case 2 which does not wrap the text to multiple lines then and the text is extending beyond the cell width. Eg -
case 1 :
Smaller text (image) (ok)
case 2 :
Multiline text multi-line text multi-line text multi...
(not ok - text not wrapped to multiple lines, remaining text and image hidden)
How to resolve this? Setting priorities to some constraints would help ?
I don't have much experience with VFL but , I know Autolayout so I can give you Idea how to resolve
I have seen your both tries
1. "H:|-[label]-[image(==20)]-|" , "V:|-[label]-|"
2. "H:|-[label]-[image(==20)]" , "V:|-[label]-|"
In first try you have fixed image on trailing
on second try you have fixed image with label
What would be combine solution ?
Your clear requirement says that you need your image attached with label trailing also take care about tailing to superview
So clear solution for that problem is
you have to give your imageView Trailing may be this code [image(==20)]-| should be changed with Greater than or equal to relation with 0 Constant
it will tells autolayout engine to keep Min 0 Distance from trailing of superview
Sorry I couldn't give you exact code as I don't have much experience with VFL
Hope it will help to you
I would like to align the start of the text of two UILabels. I aligned the two UILabels (with the yellow and grey background) and used sizeToFit: to shrink the UILabels to the content but the text is not perfectly left aligned. There is a gap on the left. The gap is bigger or smaller depending on the first character. I would like to align the red lines in the following picture. There is even a small gap with the small font in the grey UILabel but it's barely visible.
With the Z character the gap is smaller but still visible by the yellow area left to the Z
A simple UILabel alignment does not help for my specific problem, because the text content is dynamic and not static. So there could be any combination depending on the data I get from the backend. Therefore I was hoping for a UIFont or UILabel attribute that could return the size of the gap based on the current rendering of the text.
I know that there are great UIFont related attributes like baseline, capHeight and ascender one can access to align text but there seems to be no attribute that would return the value of this gap on the left.
If this doesn’t need to be two UILabels, you could have one with attributed text. Then both lines would be subject to the same layout.
I haven't tried the GUI which people have been posting Screen Shots of, however... the behaviour is consistent with the very nature of typography.
The font sizes are completely different, therefore the width of an em is different, subsequently the letter-spacing is also different.
See this: http://www.w3.org/WAI/GL/css2em.htm for more information.
I know this answer doesn't give you what you have asked for, however it should explain why this is happening.
For customisation such as this (if HTML and CSS) I would use a negative / positive margin on the sub text, however seeing as you are using backgrounds use padding (or the equivalent in your GUI).
Use attributed text of UILabel
set indentation as per your requirement

Select both the labels and add a constraint called align leading edges.
As seen on the screenshot above, each top cell has few labels. The frame of the label this question concerning is highlighted with green rectangle. It shows the title of some picture/sculpture or other exhibit, so there could be quite long strings.
I would like the text of this label to be just above author label (string with font of smaller size). So, normal text is aligned from top to bottom and if text is not enough to fill all the space, the gap is at the bottom part of the label.
For this label I would like to use the opposite approach: if text is not enough, all the text at the bottom. Is there any parameter of UILabel to implement above mentioned behaviour? Or I should manually count the amount of lines and adjust the size of the label?
This is fairly easy using constraints. To get the effect you desire:
Constrain your label's position above the author label
Constrain the label's width or horizontal position
Constrain the label to a reasonable height using a greater than or equal to
Either constrain the label's total height as less than or equal to, or constrain the vertical position to something greater than or equal to.
All these constraints can be added in IB very easily, or through code. These constraints will cause the label to grow vertically to accommodate more text, and then shrink back down with less text, which will achieve the effect of having the text grow up from the bottom.
I have a view with labels stacked vertically. The design specification for the view give a vertical offset from the baseline of the text in the top label to the text in the bottom label.
However when I code for this, the size of the top UILabel will always be big enough to accomodate the descender of the top label. So I can only program the offset from the descender, not from the baseline. In the attached picture, red offset is what I want to code for, but I can only code for the green offset. Is there any way that I can get the baseline offset correct either in the xib or through code? I do not want to do this by trial and error, as that would result in the programmed offset not matching the specs.
You can do it, but easier to show you in a screen shot than to explain it:
Change "30" to whatever your specified distance is.
I have a UILabel which autoresizes along with its parent view. The label has AdjustsFontSizeToWidth turned on and has a minimum text size of 0 - so basically it tries to fit all the text into whatever size the UILabel is.
The problem I am having is that vertically the text gets cut off. So yes, the label is adjusting its font size to the width of the label but the text is too tall for the label and thus some of the text is getting cut off.
Is there anyway to work around this so that all of the text, the full height and full width are shown?
I attach an image to show what I mean. The red box is the parent view, the purple box is the UILabel.
Thanks for your help.
What you are adjusting automatically is the Width and not the Height. The Height is something you'll have to adjust manually based on the maximum font size you will use. If the maximum (assigned initial) font size fits in height, so will the smaller one's do, after they are automatically adjusted
I suspect that Lefteris is right, that minimum text size focuses on font size for the width of the control. Note, though, if you want it to resize the font to fit, you want a non-zero minFontSize. See minimizeFontSize notes. Also check out the various NSString UIKit Additions that can be used to get the size of the control necessary to fit your text, and programmatically adjust the size (i.e. the frame) your UILabel accordingly.
In my case there was a bogus vertical centering of a view under the labels being clipped and squashed. That somehow took priority over compression resistance priority of 1000 for the labels. No warning on console about conflict though. But the view debugger was of some help.
