I have been looking for an answer to this question on google and other places, but have not found a helpful answer as of yet.
I am making an app on Xcode 4.6 using storyboards.
When drag and drop a Rounded Rectangle Button, it is fine, but when I change the background, it becomes rectangular with no rounded edges. i just wanted to change the colour of button and not anything more, but keep it rounded as the original buttons. Could someone tell me a simple method to achieve this or give me a detailed instruction as I am using storyboard and I am rather poor with XCode programming, so the little the programming, the better.
Thanks in advance.
You probably should check the UIAppearance Protocol documentation for iOS.
Meanwhile, you can use...
[[UIButton appearance] setTintColor:[UIColor redColor]];
of course, with your color.
UPDATE:
I have used an alternative method as I do not understand the suggestions which were given to me as I am not as knowledgeable about XCode programming and didn't want to take the coding route.
This may be useful for others, but what i done was that I in Photoshop, I filled the background black, used the rounded rectangle tool on the whole background and then filled the rounded rectangle with the button colour. This somewhat gave a rounded shape, but is still not as good as the original rounded buttons provided in XCode.
If anyone has any other solutions, I am free to try them out and will comment and update what I will do.
I will select the best answer by looking at which one was the simplest although I have not used that method
I suggest you to use GradientButtons

1) Define regular buttons in your storyboard files.
2) Change their class to GradientButton.
3) If you want a different color, initialize them in the corresponding view.

I have problem when in iOS settings is enabled this setting "Button Shapes"
It causing this underline in application (first picture with enabled setting, second without)
Any idea how to programatically or in storyboard disable it?
I tried attributed text but I get same result :(
I'm newbie in Swift.
Thanks for help!
It's not a problem. You should not make any attempt to counter any accessibility changes set by the user. They are there for a reason.
This is an answer by user4291543 from this question Remove underline on UIButton in iOS 7
[yourBtnHere setBackgroundImage:[[UIImage alloc] init] forState:UIControlStateNormal];
I found this answer works with SWFrameButton
And for all the others saying "Don't Do This", SWFrameButton is a very good example of when you would want to do this. I also think the OP's situation is a perfectly valid scenario as well...
I totally agree with #maddy's comment:
It's not a problem. You should not make any attempt to counter any accessibility changes set by the user. They are there for a reason.
But I did stumble on a way to accomplish the task at hand...
In addition to a UIButton, you'll also need to make a .png file that contains nothing (meaning the entire contents have an opacity of 0%). Go ahead and load that into your xcode project's assets.
Now go ahead and set the Button's Background to that image you just provided. (In my case, I called it clear) This will remove the underline from the button's text. However, now you can't see the boundaries of the button. This can be solved by changing the Background of the button's View. Go ahead and select any color for the View's Background property and now the background of the View visibly defines the button's boundaries. You're able to see this because your clear.png has an opacity of 0%.
see the Attributes inspector for UIButton here.
Rather than trying to defeat the underline by going to make a label perform some action via UITapGestureRecognizer, this allows you to still use a UIButton. Keeping inline with accessibility features to mark buttons for people that want to do that.
You could create a custom button class with a label (with clear color). If you set the text of this label instead it shouldn`t get an underline.
Are you sure you want to do that?
Apple added an accessibility feature to mark buttons for people that want to do that. Apple will probably reject your app because it defeats a system function meant to help the disabled.
I found the solution. All you have to do is set a picture as the background of the button. just pick a picture with the same color as the button you created.
I'm currently building an iOS Application for a client and have hit a pretty huge roadblock. I mean, I could write my own UINavigationBar and such but that would cause a lot of issues further down the road.
I have tried everything in my knowledge so far and have spent several hours searching for a solution (overriding the CALayer, using CoreGraphics and pretty much everything else ) and I get the same result. No matter how hard I try to remove the background of the UINavigationBar, it still shows a white background with slight translucency.
I need to have a lot of customisation on the navigation bar (I.E having a gradient going from "blackColor" to "clearColor" and I can't do that if the background of the Navigation Bar refuses to be completely transparent. I have tried copying all of the CALayers from the UINavigationBar layer to a subview I added and it just kept crashing, even when replacing the delegates and superlayer.
I really need help with this. One of the multiple effects I'm trying to achieve are below. (The blue rectangle is not the focus of the image, it's irrelevant.)
To get it completely transparent:
(UINavigationBar.appearance()).translucent = true
(UINavigationBar.appearance()).barTintColor = UIColor.clearColor()
(UINavigationBar.appearance()).backgroundColor = UIColor.clearColor()
(UINavigationBar.appearance()).setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
(UINavigationBar.appearance()).shadowImage = UIImage()
EDIT:
Using iOS 8.3 looking like this:
Or am I missing something?
You are referring to the top Navbar with the back button and Save button right? I'm just confused as to what the blue box on the image is in reference too.
Anyways, this is an extremely hacky approach but could work:
Set the UINavigationBar's alpha to 0. The Back button and Save button will probably also disappear but you could just add labels to the View Controller at the top in the exact same place. The button's should still be functional even though they are "invisible" but the user will still think they are touching them.
Again, very hacky, but you are free to play with the top part of the View then. I'm sure there's a better way to do this but I'm not near a computer with XCode at the moment and can't test it out, and this fix may not even work but I thought I'd offer up a possible temporary solution.
I have a pale green coloured tableview and when I enter Edit mode the reorder controls on the right edge are almost invisible. Can anyone tell me how to either use my own image for this or darken the system image?
I'm answering my own question because I don't want anyone else wasting time on this. You can't change this... I have resorted to switching my TableView's background colour back to white when I enter editing mode. This is yet one more horrible compromise but c'est la vie! Same with the right chevron in the accessoryView. It would seem obvious that one might be able to set this to the colour of their choice. Not so. The only way I found for doing this, simply darkening the chevron, was to subclass a UIControl and write my own drawRect method. Apple has an awful load of money yet cannot appear to employ enough programmers to keep a handle on this sort of very, very simple UI stuff. It appears that the bigger the libraries get the less we are able to actually do with them.
I am able to get reference to the backgroundImageView of the UIAlertView without using private methods etc. But my alpha setting to 1.0 is ignored. The control is still a bit semi-transparent.
Can you help?
UPDATE: I am sorry. The design team provided me with an graphical asset that had already some transparency in it. :(
So actually ,once you get a reference to the background view. You can set its alpha as you wish. Hopefully at least this information will help somebody.
The image used by Apple is already transparent, not the view displaying it.
So you won't be able to "fix" this.
A workaround might be to place another blue view below it with the same rounded corners.
I'm developing an app that calculates poker odds, and now I'm facing some problems with the card selector.
This is a mockup of what I want.
I've found two ways to accomplish this. The first one is to use an entire UIImageView and detect touches, calculate where the touch has been generated, and set the corresponding value.
The second one is to use a lot of UIButtons, but in this case I get problems with the shape of the buttons.
Of course I can use a regular UIPickerView and so on but I think that the one I've designed is better.
if you have a UIButton with a background image that is shaped irregular. then that is the only point that the button can be pressed.
Change the type to custom and put your slices into buttons.
This has been my experience anyhow.
My buttons have to have a .01 alpha background to increase their pad size and people can push the button.
Hope that helps :)
After googled a little i've found https://github.com/ole/OBShapedButton .
it does anything what i need
