The above image was taken from an Android app. I am looking to do the same thing on iOS. I know how to do it using a background image for the dots, but it doesn't look like the Android developer used an image for the dots. Anyone know how this can be done?
I've found the way to do it with content hugging/compression resistance.
Here is the interface builder solution:
Left label has a phrase and lots of dots with line breaking = truncate tail. Content hugging/compression resistance do the rest of job.
I think you can do this without any code. Just use two labels with their baselines aligned, and with a horizontal spacing constraint of 0. The left label would have its text left aligned with say 10 dots added to the end of the string, and the line break mode set to "clips". The right label would also be left aligned, so its text would always be right up against the dots.
After Edit: I couldn't get this to work in IB. It may be possible in code using constraints, but I haven't tried that. It seems like you should be able to do it with 3 labels, with the two outside ones pinned to the edges of the view, and a flexible label in the middle whose text would be dots.
You can use NSAttributedString to format in that way.
Use two colors in two ranges, even bold font for 2nd part.
And calculate the total width (length of your text) and fill dots (.) in between those.
An idea to fill dots:
lets say you have 30 characters space.
str1 contains 10, str2 contains 6, then use 30-(10+6) then in a loop
for(30-(10+6) times) {
[mainString appendString:#"."]
}

I have a scenario in which my reports fields doesn't look like centered Vertically,
Below is the screen Short of the output.
As it can bee seen from output that data with a bigger font is clearly seen centered vertically, but the data pointed with lines is left-top justified, i want that to be left-centered.
For vertical alignment I did this .
and code behind formula is:
if {NewReport;1.TireLevel} = 1
then
crCenteredHorizontally
else
crLeftAligned
The Editor Screen.
Sadly, Crystal Reports doesn't support vertical alignment in the same way it supports horizontal.
It's possible to use labels on the vertical ruler and enforce Snap to Grid, but that might not work within a table. Or you can add line breaks, blank rows, or plain white objects to push things into position. But there's no easy way to enforce a vertical center.
In your particular case, I would actually make two seperate fields: One for large text and one for small text. Layer them on top of each other and reuse your current formula to alternate their suppression. This way you can move the smaller text vertically down without undoing the vertical alignment on the large text field.
I'm trying to learn Auto Layout and playing around with various view combinations. I have various views containing other views, but the one I'm having trouble with is one that contains a label and a text field. They are set up like this:
There are several constraints set up on these, such as center Y alignment between the label, text field, and parent view, 0 leading edge for the label, and a hard coded value (12, but irrelevant) for the trailing edge of the text field. I had initially had it as a 0 trailing edge, aligning it with the parent container. However, the right edge of the text field seems to be cutting off and I have no idea why... I Started increasing the distance, thinking that may be there's a margin issue, but nothing seems to help!
Would love any input.
I have ten labels on a view positioned vertically. I need to evenly space them. Does IB have any type of setting that will do this?
If you select individual labels and drag them around the view, they should "snap" to certain guides around the interface. If you drag an element close to another element it should snap to about 8 pixels away, and that's the standard spacing between elements on the iPhone.
If you want more precise control, you can select an element and use the arrow keys to move it around one pixel at a time.
You can also use the Align Horizontally/Vertically in Container menu items from the Layout menu.
Do the math and then type in the X,Y coordinates. Unfortunately, I think that is the easiest way.
If you are OK using Apple's guideline spacing, dragging one label near another will generate a dashed line at a certain point. Do this for each label below the next, and they will be evenly spaced.
I have two strings:
a variable length piece of text
another string with numbers that
point to a reference
In my view, the first piece of text is displayed in a UILabel, I adjust the size of the label to accomodate the size of the text. This means I cannot just place another UILabel on the screen, at least not without repositioning it...somehow.
I need to be able to put the second piece of text so it appears to be at the end of the sentence - and superscripted
I really have no idea how to achieve this!
My rather dodgy solution was to enter unicode characters for the superscripted numbers.
Not a great solution but it worked.
The simplest way would be to use two different UILabels. A better solution might be to draw both strings using -drawInRect:withFont: in a custom view's -drawRect: method.
I have a label and I wish to increase the spacing between characters.
I tried adding a space between each character, but this was too much
Perhaps there is a font with large spacing between the letters?
If all else fails, I am considering putting each character (only a size character code), into its own textbox.
Any ideas on how to achieve this?
There is a way to insert a half space, but I don't recall the exact command (option-spacebar?). Wikipedia has a complete list of spaces you can use.
Another approach would be a UIWebView with the letter-spacing CSS attribute set.
You're better off creating a custom view and using your drawRect routine to draw the text manually. You can use CFAttributedString to hold your text along with kerning information.
Update: sounds like you can't actually use CFAttributedString to draw text on the iPhone. You can still use your drawRect to draw the customized text, but it will take some more work to actually get your custom kerning to work.
