Rounded edges are getting kind of old, and I want my program to have a modern edge. Any idea how this can be done?
To clarify: I want the exact functionality of UITextField without rounded corners.
EDIT: Sorry, I'm a dumbass. I couldn't find the button because the textbox wasn't selected.
{insert facepalm emoticon here}
Just to help anyone who still runs into this, since it isn't clear enough you can use the Storyboard/Xib Interface Builder:
You can just change the borderStyle property of your UITextfield, or provide your own background image by setting backgroundImage property, here is a ref UITextField reference
Subclass UITextfield and override the drawrect: method. I think this should solve your problem.
You can modify a standard UITextView created in Interface Builder in viewDidLoad as follows:
[_textField setBorderStyle:UITextBorderStyleNone];
[_textField setBackgroundColor:[UIColor whiteColor]];
This can also be set the border style and background color directly in Interface Builder.
You need to set a background image and the background color.
UITextField *txtSearchField = [self.searchDisplayController.searchBar valueForKey:#"_searchField"];
[txtSearchField setBackgroundColor:[UIColor whiteColor]];
[txtSearchField setBackground:[[UIImage alloc]init]];

I was wondering how you would hide an image in Objective-C.
I know you can hide text or a button like this
StartGame.hidden = YES;
But when I try to do this with an image, i get an error.
Since UILabel, UIButton, UIControl and UIImageView are all childs from UIView they all have the hidden property to hide them.
So any instance of the of a view (or its childs) can be hidden by setting the hidden property to YES.
If your UIImageView is part of your viewcontroller it would make sense to make a property of it rather then just an variable, but I can not see your full code or error to say that the error might be found there.
Also property or variables should not start with a capital, its not in line with the Objective-C style.
UIImageView *ImageView=[[UIImageView alloc] initWithFrame:CGRectMake(x, y,width, height)];
[ImageView setImage:[UIImage imageNamed:#"image.png"]];
and to hide this image You just need to write
[ImageView setHidden:YES];
I want to change the picker view bakground color. I try this way but not worked.
doublePicker.backgroundColor = [self RGBColorR:85 G:17 B:92];
- (UIColor *)RGBColorR:(double)red G:(double)green B:(double)blue {
return [UIColor colorWithRed:(red/255.00) green:(green/255.00) blue:(blue/255.00) alpha:1.00];
}
I want to do picker view like in picture. How can I do this? Thanks for your reply.
you can add subviews over certain areas of your pickerview..
use:
[picker addSubview: coverView]; //adding subviews to different area of the picker
you're going to find yourself playing with alot of CGRect to get thing to fit properly. If you want to change the entire thing you're going to have to override some methods that handle the touch events etc..
this tutorial might help you create a custom picker
https://developer.apple.com/iphone/library/samplecode/UICatalog/
You cannot change the appearance of UIPickerView, even the size, it's the most unchangeable UI element in iOS. Best you can do is build custom by yourself, using UIScrollView with paging enabled.
Is it possible to customize the image of the clear button in a UITextField? I have a dark textfield background and the "x" is not visible enough.
You can set your own custom clear button to the text field's rightView property. Make sure set the rightViewMode property to UITextFieldViewModeWhileEditing or UITextFieldViewModeAlways, whatever makes sense for your case.
If the button's position isn't right for your need, you can subclass UITextField and override the rightViewRectForBounds: method.
The documentation says the default for the clearButtonMode property is UITextFieldViewModeNever, but I suspect Interface Builder may set it to UITextFieldViewModeWhileEditing - Make sure you set it to the "never" value so it doesn't appear.
All these properties are documented in UITextField Class Reference.
You can access that property using KVO:
UIButton *clearButton = [myTextField valueForKey:#"_clearButton"];
[clearButton setImage:[UIImage new] forState:UIControlStateNormal];
Tested iOS7.0 - 8.4
It is possible to update the backgroundImage of all clear buttons using the following UIAppearance method. Unfortunately you cannot update the image of the button:
UIButton *defaultClearButton = [UIButton appearanceWhenContainedIn:[UITextField class], nil];
[defaultClearButton setBackgroundImage:[UIImage imageNamed:#"clearButtonBkg1.png"] forState:UIControlStateNormal];
Using the following images, this results in the following clear button:
White background image #3x:
Note: This will update the background image of ALL buttons contained in textfields
Swift 2.2+ / iOS 9+ version of #Brody Robertson's answer:
let defaultClearButton = UIButton.appearanceWhenContainedInInstancesOfClasses([UITextField.self])
defaultClearButton.setBackgroundImage(UIImage(named: "ClearIcon"), forState: UIControlState.Normal)
Swift 3
let customClearButton = UIButton.appearance(whenContainedInInstancesOf: [UITextField.self])
customClearButton.setBackgroundImage(UIImage(named: "custom_cb"), for: .normal)
depends on #Tuss László's answer
Swift 3.0
myTextField.clearButtonMode = .whileEditing
if let clearButton = myTextField.value(forKeyPath: "_clearButton") as? UIButton {
clearButton.setImage(UIImage(named:"myImage"), for: .normal)
clearButton.setImage(UIImage(named:"myImage"), for: .highlighted)
}
But really use it carefully. If Apple change implementations in future iOS releases, it would not be work
One approach would be to create a custom UITextField that has your desired image as a subview and clears the parent text field when tapped. You disable the default button and add your custom behavior in this custom text field.
This should get you started. If there are any more concrete questions, feel free to edit your question or comment here if it's a minor problem.
I try to display a UITextfield with a black background.
But with this black background, the clearButton is not visible.
I can touch it... because I know where is supposed to be, but until
I touch it, nothing is visible.
Here's my code:
textField.background = [UIImage blackColor];
textField.clearButtonMode = UITextFieldViewModeAlways;
How I can make the clearButton to appear ?
Thanks !
You'll need to draw and manage your own clear button, because there's no API for changing the appearance of the built-in button. Read about the rightView and rightViewMode properties of UITextField.
I think you may want to use UIColor to set the background:
textField.background = [UIColor blackColor];
I've created a subclass of UITextField. In this subclass, I used rightView to add and handle a custom delete button. This is the only solution I've found.
I'm trying to create a label programmatically using NSTextField, but it comes out blurry: screenshot
This is my code so far:
NSTextfield *textfield = [[NSTextField alloc] initWithFrame:NSMakeRect(5,5,150,20)];
[texField setStringValue:#"some text here"];
[textField setEditable:NO];
[textField setSelectable:NO];
[textField setBordered:NO]
[textField setDrawsBackground:NO]
I've traced the problem down to the setDrawsBackground line. I've also tried using [textField setBackgroundColor:[NSColor clearColor] as well, but no luck.
By the way, I've adding to a textField to the subview of a view that is a subview of a scrollview. I've also playing with isOpaque on all the view levels, but no luck there again.
Any help is greatly appreciated.
If you have no background (including clear) and your text is a subview of any layer-backed superview (you've turned on "wants layer" in code or in IB to allow animations/transitions), you'll get blurry text. You have to choose either no layer backed view or a label with a solid background color.
I had the same problem, but I have solved it by:
textfield.canDrawSubviewsIntoLayer = true
Make sure you're setting the frame of your NSTextField to something with all integer values.
Use roundf() if necessary.
I was getting a blurry NSTextField, and neither adding a solid background nor removing Core Animation layers from my view hierarchy were options for me. I noticed I was setting the frame of this text field to something with a Y value of 4.5, so the following changes fixed the issue for me:
Blurry label:
_label.frame = NSOffsetRect(_labelFrame,
-0.5 * (someRect.size.width + someConstant),
0.0);
No blur:
_label.frame = NSOffsetRect(_labelFrame,
roundf(-0.5 * (someRect.size.width + someConstant)),
0.0);
(In the above examples, _labelFrame and someRect are NSRects, and someConstant is a CGFloat. As you can see, the calculation I was doing in the second line of the first example was passing a non-integer value to NSOffsetRect).
Since this was my first time subclassing NSView, I had put the above code in the drawRect method instead of the initWithFrame method. I did this because I was following one of the sample applications from Apple's Dev site.
This was also causing my CPU usage to spike when I was scrolling
If you created it via an XIB and it is blurry, I found the fix:
[textField setStringValue:#""];
If I comment this out it goes blurry; if put back it's crystal clear.
Try this below:
textField.drawsBackground = true
textField.backgroundColor = NSColor.white.withAlphaComponent(.leastNormalMagnitude)
Out of the box, but worth to mention. I have wasted by entire day debugging the issue. I am using a non-apple external monitor and this is where the issue is identified. Once i open the app in Mac book pro, it is perfectly fine.
So, the Samsung monitor which i am using might be non-retina.
Simply, add
CanDrawConcurrently = true
property from InterfaceBuilder
