hi i want to resize my button width by text length when adding title right insets
i tried set Constant 100 and Priority 1000 and it work perfect
but when i add image and right insets,
button title show like this
"apple...omputer"
and i tried this
button.invalidateIntrinsicContentSize()
and
button.sizeToFit()
still not work and still show "..." in my button text
and i tried to add width after set button title in viewdidload, but still not working
button.frame = CGRect(button.frame.origin.x, button.frame.origin.y, button.frame.width+50, button.frame.height)
Storyboard buttons
Resizing button because text became larger
Please look at screenshots above. You need to set your insets and set right constraints. Autolayout does it for you.
It might be a silly question.
I'm trying to set left/right margins like the attached picture. I succeeded to implement it by adding UITextView to UIScrollView.
However, I could achieve almost everything I want with UITextView alone. For example, with UIScrollView, when I manually change the text of UITextView, it automatically scrolls to bottom regardless of setting its .scrollEnabled to No.
It would be perfect if a scroll indicator of UITextView appears outside UITextView.
In the attached picture, let's say the red box represents the entire UITextView. I tried to change UITextView's scrollIndicatorInsets property, but a scroll indicator can be moved only inward to be visible.
Several apps such as Pages, aWriter, Plaintext achieve this feature.
Could you give any suggestion?
Thank you!

You can set the scroller right inset value of the UITextView to negative value and disable the clip subview option to achieve your require. No other scrollview is needed.
Alternatively you could set the Right contentInset property.
UIEdgeInsets insets = textView.scrollIndicatorInsets;
insets.right += 5; //add what ever is your margain
textView.scrollIndicatorInsets = insets;
Because the navigationItem.rightBarButtomItem is customized, it will occupy a big place and the title view won't be on the center.
For example, I want the "OMG" is located at the center between buttoms of "Home" and "Group".
How to achieve this?
Change the rightBarButtonItem to Camera and Setting... and add Group Button as subview to the navigation bar.. do some trial and error to adjust the x position for the Group Button....
If you have fix titleView as "OMG" good.. if not then it will be little tricky to position the titleView with longer text but it can be done..
make the title part of the navigationItem.rightBarButtomItem, this seems to be the best way to make sure it is positioned correctly.
In my UIViewController i set my title dynamically so i do not know the length of the string that will be shown in the navigation bar and because of that i have the current situation:
alt text http://img94.imageshack.us/img94/2484/picture3vf.png
is there any way to set the width of the label that displays the title in the navigation bar? or should i think of a with, compare the text length to it and if it is too long should i resize it and display the famous "..." ?
I know that i can add an UILabel as subview to the navigationBar but i don't want to use that solution.
Thank you!
Maybe you could add some dummy buttons to the navigation bar that will sit directly underneath your buttons. That would show the normal text behavior, but also allow you to play with your colors.
I'm not sure how you did that. If I'm creating a navigation view and setting a title that is too long it will be shortened with "..." by default. These black buttons do not seem to be default buttons.
You can use sizeWithFont method of NSString to know the size your label will take. Note that you can add a maximum size if you know your label width shouldn't be greater than a certain value
// Get the size really needed for the label string
CGSize expectedLabelSize = [self.text sizeWithFont:self.font
constrainedToSize:maximumSize
lineBreakMode:self.lineBreakMode];
i created a UITextField of type rounded textfield, using Interface Builder,so in order to set the Height of a textfield its window was disabled(not to set any height manually) in SizeInspector.so if we want to set height manually,what procedure should we follow.
One thing i would like to mention is ,we can do that in coding part,but what i would like to know is ,how can we acheive that in interfacebuilder.
Answers from you were always appreciated.
Change the border style, like this:
Unfortunately you can't set the Height of a UITextField using Interface Builder. You will have to set it programatically and be sure it doesn't break any rules from iPhone Human Interface Guidelines
You can change the height of UITextField by editing the .xib file. Just open it using Textedit or Dashcode and search for the IBUITextField. Edit to NSFrame parameter to whatever size u want.
increase the size of the font and the box's height will increase
Change the Border Style property of the text field to something other than the rounded rectangle. After that you can freely set the height of the box.
Right click on .xib file and click on "Open As"-> "Source Code". Then search for UITextField's NSFrame. Change the height as you want.
Successful solution with my condition:
After trying all above ways, I could not change the height of UITextField.
Finally, I found out that I put UITextField in stack view (or it was affected by some constraints).
So, I added Height Constraint for UITextField then put my expected height in Constant of Constraint.
And it works.
Specially, it works for all Border-style (None, Line, Bezel, RoundedRect).
No code is needed.
After a bit of playing around, I realized that UITextField can be thought of as a UIButton (Rounded rect style) with a UILabel on top of it. Or, it is a UITextView on top of UIButton Rounded rect style. The number of lines, dimensions and position of the label inside the button can be easily adjusted in IB.
In my case, I wanted a read only text-field so I used UILabel on top of UIButton. I adjusted the size of button as per requirement and also label size. I also had to uncheck the 'Enable' box for the button in IB so that it does not get highlighted on touching.
You can easily change that using source code. Just right click on your storyboard, open it as source code, then search for your text field and change the height.
The easiest way that i have found to accomplish this is to change the border style and then edit the other attributes to your liking. Here's an example.
emailField.layer.borderColor = [[UIColor blackColor] CGColor];
emailField.layer.borderWidth = 2.0f;
emailField.layer.cornerRadius = 8.0f;
emailField.alpha = .75f;
emailField.layer.backgroundColor = [[UIColor whiteColor] CGColor];

I resolved textfield (with rounded rect) height problem. You must define height constraint for your textfield object.
Define height constraint for Textfield.
We can change height of Text Field with any type of border style other than rounded rectangle by simply dragging. But for the Rounded Rectangle Text fields it is not possible...of course we can change height using some code.
And here I found a simple way. It worked for me
Select the text field and at the below right corner we can see the pins option..
There select the height constrain it is 30 pre-defined...
select that height and you can see "Add 1 Constraint" is enabled.
Click on that..therefore we have added height constraint for that text field.
Now go to the size inspector. There find the Height constraint in "Constraints"...which is above the "Content Hugging Priority"
You can edit the height there...give whatever value you want to give. Now see the textfield it is changed to its height which you have given.
It worked for me :) Can use this scenario for UISwitch, Segment, etc..
As #peterdoesco.de said, Just add an Height constraint, and change it's value, this can works fine.
