When working with a muti-line UILabel object, is there a way to know at which position in the text the line wrapping will occur?
For example if the text of my label is 20 words, the display will be different according to the size of the box provided. I would like to know when (character position) the display is going to the next line.

I want to have a text box which allows you to enter the size of a grid, like the width and height. I want the text box to have a comma in the center so you can put the width on the left of it and the height on the right. (width,height)
How can I add this comma in and make it so it can't be changed by the user and acts as a divider between the values of the width and height.
You can use a MaskedTextBox rather than a TextBox, this will let you set an input mask for the required input, however you may need to fix the number of digits.
I have an NSTextView control object wrapped with NSScrollView. What I want to do is to make the text string at the current position visible when it's hidden below the content view.
In reference to the picture above, with
NSUInteger cPosition = [[[textView1 selectedRanges] objectAtIndex:0] rangeValue].location;
[textView1 scrollRangeToVisible:NSMakeRange(0,cPosition)];
the scroll view will scroll itself to a position such that the selected string (document) will come at the bottom of the content view. (Line 11). That's not exactly what I want. I would like the scroll view to scroll itself to show the text string at the current cursor position when it's hidden below the content view (for example, at Line 14). How can I improve my code?
Muchos thankos.
One solution would be to use NSString's enumerateSubstringsInRange:options:usingBlock: method with the NSStringEnumerationByParagraphs option and passing the range that contains your cPosition to scrollRangeToVisible:. This would have the effect of making the paragraph that contains your cPosition visible.
I've a UITextField and a UILabel on it. The label is right aligned and the text is left aligned, the problem is that when i enter text in text field, whenever the size of text goes bigger it overlap the label.
How can i prevent the label to be overlapped?
Updated:-you can use table view cell of type value1 or value2 that gives you this format and Used TextLabel as main heading and place the textfield in place of detailtext.That can be fix.
Hi I have a button which will add a string in to a label. (this can be done multiple times.) As the user can add multiple strings with each one been a different length, is there anyway I can get it to find the length of the label and those around it so that it spaces out correctly?
Thanks
Label.Width will return the current width of the label control, but it sounds like you already know this. Since the label can be narrower than the text it is trying to display, you would need to measure the full text using the graphics object. This method will return the width of the text in a label:
Private Function getFullTextWidth(lbl As Label)
Using g As Graphics = Label1.CreateGraphics()
Return g.MeasureText(Label1.Text, Label1.Font).Width
End Using
End Function
Alternatively, you could just set the label's AutoSize property to true, and then just check the label's Width property after you set the Text.
I have added Label to my ViewController.xib.
The problem is that when the text of the label is too long, and only part of the text is seen. It would not go to the next line.
How can this be done?
Set the property either programatically with:
#property(nonatomic) NSInteger numberOfLines
or in interface builder.
Here are the docs:
This property controls the maximum number of lines to use in order to fit the label’s text into its bounding rectangle. The default value for this property is 1. To remove any maximum limit, and use as many lines as needed, set the value of this property to 0.
If you constrain your text using this property, any text that does not fit within the maximum number of lines and inside the bounding rectangle of the label is truncated using the appropriate line break mode.
When the receiver is resized using the sizeToFit method, resizing takes into account the value stored in this property. For example, if this property is set to 3, the sizeToFit method resizes the receiver so that it is big enough to display three lines of text.
