scrollView = [[UIScrollView alloc] initWithFrame:
[[UIScreen mainScreen] applicationFrame]];
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(25, 100, 200, 250)];
textView .text =#"long text ";
I will be getting some data of unknown length. to be added to the UITextView . Sometimes the height of the content of the text might exceed the height of the UITextView which is 250 (shown above).
How can i increase the height of the UITextView based on the text i receive ? I would appreciate a sample code? Later i need to add this to a UIScrollView (i know how to add to a scrollview), but again i don't know how to increase the height of the scrollview. Can someone help me code this ?
note: according to my code i am defining the width and height of the UITextView before adding the text to it.
UITextView is a subclass of UIScrollView. When the text content grows larger than the frame of the text view, the content will automatically begin to scroll. There is no need to embed a UITextView in a UIScrollView because it already is one (and more!).
Set the size of textView equal to it's contentSize.
The scrollView you have to set it's contentSize equal to the size you want.
I am using a UITextField. I want to increase its height but I have not found any property to do this. How can I achieve this?
You can not change the height of the rounded rect border style.
To set the height, just choose any border style other than rounded border in Xcode:
I finally found the fix for this!
As we have found, IB doesn't allow us to change the height of the rounded corner border style. So change it to any of the other styles and set the desired height. In the code change the border style back.
textField.borderStyle = UITextBorderStyleRoundedRect;
CGRect frameRect = textField.frame;
frameRect.size.height = 100; // <-- Specify the height you want here.
textField.frame = frameRect;
If you are using Auto Layout then you can do it on the Story board.
Add a height constraint to the text field, then change the height constraint constant to any desired value. Steps are shown below:
Step 1: Create a height constraint for the text field
Step 2: Select Height Constraint
Step 3: Change Height Constraint's constant value
1.) Change the border Style in the InterfaceBuilder.
2.) After that you're able to change the size.
3.) Create an IBOutlet to your TextField and enter the following code to your viewDidLoad() to change the BorderStyle back.
textField.borderStyle = UITextBorderStyleRoundedRect;
Swift 3:
textField.borderStyle = UITextBorderStyle.roundedRect
Choose the border style as not rounded
Set your height
in your viewWillAppear set the corners as round
yourUITextField.borderStyle = UITextBorderStyleRoundedRect;
Enjoy your round and tall UITextField
Follow these two simple steps and get increase height of your UItextField.
Step 1: right click on XIB file and open it as in "Source Code".
Step 2: Find the same UITextfield source and set the frame as you want.
You can use these steps to change frame of any apple controls.
An update for iOS 6 : using auto-layout, even though you still can't set the UITextField's height from the Size Inspector in the Interface Builder (as of Xcode 4.5 DP4 at least), it is now possible to set a Height constraint on it, which you can edit from the Interface Builder.
Also, if you're setting the frame's height by code, auto-layout may reset it depending on the other constraints your view may have.
I know this an old question but I just wanted to add if you would like to easily change the height of a UITextField from inside IB then simply change that UITextfield's border type to anything other than the default rounded corner type. Then you can stretch or change height attributes easily from inside the editor.
swift3
#IBDesignable
class BigTextField: UITextField {
override func didMoveToWindow() {
super.didMoveToWindow()
if window != nil {
borderStyle = .roundedRect
}
}
}
Interface Builder
Replace UITextField with BigTextField.
Change the Border Style
to none.
My pathetic contribution to this dumb problem. In IB set the style to none so you can set the height, then in IB set the class to be a subclass of UITextField that forces the style to be rounded rect.
#interface JLTForcedRoundedRectTextField : UITextField
#end
#implementation JLTForcedRoundedRectTextField
- (void)awakeFromNib
{
self.borderStyle = UITextBorderStyleRoundedRect;
}
#end
It kept me from having to hack the XIB file or writing style code into my view controller.
A UITextField's height is not adjustable in Attributes Inspector only
when it has the default rounded corners border style, but adding a
height constraint (plus any other constraints which are required to
satisfy the autolayout system - often by simply using Add Missing
Constraints) to it and adjusting the constraint will adjust the
textfield's height. If you don't want constraints, the constraints can
be removed (Clear Constraints) and the textfield will remain at the
adjusted height.
Works like a charm.
In Swift 3 use:
yourTextField.frame.size.height = 30
try this
UITextField *field = [[UITextField alloc] initWithFrame:CGRectMake(20, 80, 280, 120)];
UITextField *txt = [[UITextField alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
[txt setText:#"Ananth"];
[self.view addSubview:txt];
Last two arguments are width and height, You can set as you wish...
You can use frame property of textfield to change frame
Like-Textfield.frame=CGRECTMake(x axis,y axis,width,height)
This is quite simple.
yourtextfield.frame = CGRectMake (yourXAxis, yourYAxis, yourWidth, yourHeight);
Declare your textfield as a gloabal property & change its frame where ever you want to do it in your code.
Happy Coding!
If you're creating a lot of UITextFields it can be quicker to subclass UITextViews and override the setFrame method with
-(void)setFrame:(CGRect)frame{
[self setBorderStyle:UITextBorderStyleRoundedRect];
[super setFrame:frame];
[self setBorderStyle:UITextBorderStyleNone];
}
This way you can just call
[customTextField setFrame:<rect>];
I was having the same issue. tried some of the solutions here but rather than doing all this mumbo-jumbo. I found just setting height constraint is enough.
I wanted to know is it possible to get the height of a multi line UILabel? I'm developing a messaging application and wanted to achieve something like the iPhone messaging application.
You can get the property with label.frame.size.height
You probably want the -[UILabel sizeThatFits:] method. Here's what you do. Let's say your UILabel is in the variable myLabel, and you've already set its width to whatever you want.
myLabel.text = #"This is my very long message which will probably need multiple lines to be displayed because it is very long.";
CGRect bounds = myLabel.bounds;
// Create a size that is the label's current width, and very very tall.
CGSize prototypeSize = CGSizeMake(bounds.size.width, MAXFLOAT);
// Ask myLabel how big it would be if it had to fit in prototypeSize.
// It will figure out where it would put line breaks in the text to
// fit prototypeSize.width.
CGSize fittedSize = [myLabel sizeThatFits:prototypeSize];
// Now update myLabel.bounds using the fitted height and its existing width.
myLabel.bounds = (CGRect){ bounds.origin, CGSizeMake(bounds.size.width, fittedSize.height) };
If you call
[label sizeToFit];
it will resize the UILabel to the minimum size needed to hold all the content. Then you can just do label.frame.size.height to get the height of the label with that amount of text in it.
The above is what I get on the simulator regardless of the frame I set for the UITextView. The above UITextView is a subview to UIScrollView (the light gray view behind). And this UIScrollView has been presented modally. No matter what frame I set for the UITextView, its height remains as shown above. What could be the problem?
scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 540, 620)];
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(10, 10, 520, 80)];
textView.contentInset = UIEdgeInsetsZero;
textView.layer.borderWidth = 1.0f;
textView.layer.borderColor = [[UIColor blackColor] CGColor];
[scrollView addSubview:textView];
Thanks!
Noted one more thing. Changing the width of the textview from say the above 520 to 220 does indeed result in a change of width and it shows. But no matter what the value of height is, the textview keeps displaying with the same height as in the above image.
your UITextView size is dependent on the Height and width of UIScrollView first increase the size of UIScrollView size than increase th eUITextView size.
I'm getting the same issue and when I try to po the frame height it give me:
property 'frame' not found on object of type 'UITextView *'
This is after installing the new ios6 dev kit... so maybe that's it...
Yup that's it. If you go to file inspector in your xib or storyboard and untick "use autolayout" then that will help.. But's it's screwed everything, so I'm just going to make the damned uitextview programatically!
I already did several searches on Stack Overflow and Google, but I couldn't find a solution to my problem.
I have a Detail View for a product that includes a UIScrollView and a few subviews (UIImageView, UILabel, UITextView). You can find an example here.
First I wanna autoresize the UITextView (not the text itself!) to the corresponding height. Then I wanna autoresize the entire UIScrollView so that it fits the height of my UITextView and the elements above it. I've tried the following code:
myUITextView.frame = CGRectMake(2.0, 98.0, 316.0, self.view.bounds.size.height);
[scrollView setContentOffset:CGPointMake(0.0, 0.0) animated:NO];
scrollView.contentSize = CGSizeMake(320.0, 98.0 + [myUITextView frame].size.height);
[self.view addSubview:scrollView];
98.0 + [myUITextView frame].size.height) because my thought was: After getting the height of myUITextView, add the height of the other subviews (98.0) to it.
Unfortunately it doesn't work very well. Depending on the content of the UIScrollView, it is too short or too long. I did some logging with the result that the height of the UITextView is always the same:
2010-01-27 14:15:45.096 myApp[1362:207] [myUITextView frame].size.height: 367.000000
Thanks!
There is actually a very easy way to do resize the UITextView to its correct height using its contentSize.
CGRect frame = _textView.frame;
frame.size.height = _textView.contentSize.height;
_textView.frame = frame;
One thing to note is that the correct contentSize is only available after the UITextView has been added to the view with addSubview. Prior to that it is equal to frame.size
A UITextView won't automatically resize itself to it's contents (not as far as I know anyway) so you need to get the size of the text yourself and size the UIView accordingly.
The functions on this page will help - you can use them to get the width and height of a string, something like
// Get the size that the string will render at
NSString *contents = #"This is the content of your UITextView";
CGSize areaSize = [contents sizeWithFont:myView.font forWidth:myView.frame.size.width lineBreakMode:UILineBreakModeWordWrap];
// Then set the frame of your UITextView to be the right size
myView.bounds = CGRectMake(0, 0, areaSize.width, areaSize.height);
Then, you can layout the other components around it.
Hope this helps,
S
PS Warning, the link to the docs is correct but my code example is untested, sorry :)
