I am using a text label to display previously entered user information that has been saved. I am having trouble fitting the whole date and time in one line. Any information that goes beyond a specific length does not appear in the label. I attempted to do two things:
1) make the label larger (this didn't do anything to help with keeping the text within the label)
2) change the "line breaks" option under the attributes inspector to "word wrap". This didn't solve my problem either
How do I make it so that I can include all of the date/time information in the same label, just with wrapped text, so that the text that goes beyond the edge of the screen wraps to the next line?
The code below shows the creation of the view, the screenshots capture what it looks like in the app (some text in "date and time" section not included) and the settings I have set in the storyboard for the label "date and time"
Creating the view:
- (void)configureView
{
Event *theEvent = self.event;
static NSDateFormatter *formatter = nil;
if (formatter == nil) {
formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"cccc, MMMM dd, yyyy hh:mm a"];
}
if (theEvent) {
self.detailLabel.text = theEvent.detail;
self.locationLabel.text = theEvent.location;
self.dateTimeLabel.text = [formatter stringFromDate:(NSDate *)theEvent.date];
}
}
The line breaks option only works when you set the number of lines to zero and the label is tall enough to contain more than one line. You can call sizeToThatFits: to get an appropriate size for the label.
You can also use the autoshrink option to automatically make the text smaller when needed.

I have a single line UILabel. It has width = screen width and the content now is (the content of UILabel can change)
You have 30 seconds to make an impression during an interview
Currently, my UILabel is truncated tail and the word "duration" is not complete
self.nameLabel.lineBreakMode = NSLineBreakByTruncatingTail;
What I want is I want my UILabel still truncating tail and only display complete word.
Like the image below
Any help or suggestion would be great appreciated.
You can do something like this:
let labelWidth = CGRectGetWidth(label.bounds)
let str = "You will have 30 seconds till you give us a good impression" as NSString
let words = str.componentsSeparatedByString(" ")
var newStr = "" as NSString
for word in words{
let statement = "\(newStr) \(word) ..." as NSString
let size = statement.sizeWithAttributes([NSFontAttributeName:label.font])
if size.width < labelWidth {
newStr = "\(newStr) \(word)"
}
else{
break
}
}
newStr = newStr.stringByAppendingString(" ...")
self.label.text = newStr as String
Idea is: we split words and try check the width while appending from the beginning + the string "..." till we found the a word that will exceed the size, in the case we stop and use this new string
Ideally this is not possible,with default UILabel, when you set lineBreakMode to TruncatingTail, depending on the space required by the letter/word the OS will truncate it, one solution to fix the issue you can use following properties depending on your match.
Minimum Font Scale -- Use this property to specify the smallest multiplier for the current font size that yields an acceptable font size to use when displaying the label’s text. If you specify a value of 0 for this property, the current font size is used as the smallest font size.
Minimum Font Size -- When drawing text that might not fit within the bounding rectangle of the label, you can use this property to prevent the receiver from reducing the font size to the point where it is no longer legible.
i am not sure but try it:
nameLabel.adjustsFontSizeToFitWidth = NO;
nameLabel.lineBreakMode = NSLineBreakByWordWrapping;
OR
If you are using storyboard follow these steps i tried this and it working fine
Open Attribute Inspector
Change Line Breaks to Truncate Tail then
Change AutoShrink to Minimum Font Size
here are my screenshots of label after and before applying these properties
new output

I am relatively new to xCode and I have 2 integer text labels Text1 and Text2 text.
I'm looking for some code that would compare if Text1.text is greater than Text2.text and then if another text field Text3.text would be equal to the value of Text1.text.
Appreciate any help.
In the attributes inspector I assume. Select the text, go to attributes inspector (top right corner at the utility area, forth in a row. Looks like a square head with ears) and check the size.
Well, if you want xcode to check the size, you'll need to make an if or switch statement. Use enums like .fontSize
The text fields are just views that display a string.
You can access the string that they contain via the text property:
NSString *text1 = _text1.text;
Now you have the string that is displayed in the textview ( "34" for example)
You can use the NSString method intValue to turn this string into an integer:
int text1Value = [text1 intValue];
You can now compare the value of this to another integer:
if (text1Value > 42) {
_textLargest.text = [NSString stringWithFormat:"%d", textValue1];
}
Main points:
Text fields are just views; you need to work with the data they are displaying rather than treat them as objects
You need to use the correct type for your comparison. The text field contains text but you need to convert it to a number to make it meaningful
You need to convert the number back into a string if you want it to appear in the text field's text property [NSString stringWithFormat:"%d", textValue1]
You can take and compare the int values as follows
if([Text1.text intValue] > [Text2.text intValue] )
{
Text3.text=[NSString stringWithFormat:"%#", Text1.text];
}
My app includes a text formatting tool that offers buttons for things like bold, italic and color and shows the formatted text by generating an NSAttributedString and setting that to the attributedText property of a UITextView. After the user selects text and taps a button, I get the selectedRange property of the UITextView, then get the current attributedText property of the UITextView, add another attribute to the text based on the selected range, and then assign it back to the attributedText property of the UITextView again.
Starting with iOS 7, my text formatting started displaying at the wrong location in the text, usually shifted a couple characters forward. After some testing I noticed that this only happened after an empty line (e.g., a paragraph of text with two line breaks after it) and the formatting was offset by one character for each empty line proceeding it.
After more testing I found that when I set the attributedText property for the first time, any sequence of two line breaks is changed to a line break, then a "line separator" character (Unicode 8232) and then the second line break. The new characters are definitely added by the attributedText assignment, as I can see from outputting the integer value of each character immediately before and immediately after that action. However, the selectedRange property of the UITextView ignores the line separator characters, so any range that it returns is now incorrect.
I've already found a workaround, which I'll add as an answer in a moment. I'm mainly posting this in case anyone else is having problems with it. Also, I've reported this to Apple as bug 15349335.
I wrote this method to adjust ranges returned by the selectedRange property to account for these extra line separator characters:
- (NSRange)adjustRangeForEmptyLines:(NSRange)range inText:(NSAttributedString *)text byChars:(int)chars {
int emptyLinesBeforeRange = 0;
int emptyLinesWithinRange = 0;
for (int i=0; i<(range.location + range.length); i++) {
int thisCharacter = [text.string characterAtIndex:i];
//NSLog(#"thisCharacter: %i", thisCharacter);
if (thisCharacter == 8232) {
if (i < range.location) {
emptyLinesBeforeRange++;
} else {
emptyLinesWithinRange++;
}
}
}
//NSLog(#"found %i + %i empty lines", emptyLinesBeforeRange, emptyLinesWithinRange);
range.location += (emptyLinesBeforeRange * chars);
range.length += (emptyLinesWithinRange * chars);
return range;
}
I can set the byChars argument to 1 or -1 depending on which way I want to adjust. This has been working for me for a few weeks now, but if anyone has an alternate solution, I'd be curious to see it.
I have a UITextView that has a fixed width and height. I pre-populate the entire textfield with blanks.
I would like to insert a character with the push of a button that will erase the last blank character, insert my string character and then place the cursor at the beginning of the newly inserted string. I am trying to achieve inserting special fonts right to left and bottom to top.
It is working with the first button push and on the second button push the new value is inserted in the correct position to the left, however, the cursor will not move to the left after the second button push, it remains to the right after the second string insert.
Here is my code...
-(IBAction)chartP:(id)sender {
NSRange currentRange = myChart.selectedRange;
if (currentRange.length == 0) {
currentRange.location--;
currentRange.length++;
}
myChart.text = [myChart.text stringByReplacingCharactersInRange:currentRange
withString:[NSString string]];
currentRange.length = 0;
myChart.selectedRange = currentRange;
myChart.text = [myChart.text stringByAppendingString:#"p"];
myChart.selectedRange = NSMakeRange(myChart.selectedRange.location -1, 0);
}
Can someone assist me with what I am missing here to continually increment to the left with my string inserts?
How about flipping the text area:
myChart.transform = CGAffineTransformMakeScale(-1,-1);
It sounds like you are trying to implement right-to-left text direction by faking it. Why not do the real thing?
Here's a question that covers the topic:
Change the UITextView Text Direction
If you need bottom-to-top entry, and you have the ability to use a custom font, perhaps you can apply a transformation to the UITextView and y-flip it. Look at the transform property of UIView. (Things like the text selection loupe may break, but it's worth a try.)
