I want to hide LeftCalloutAccessoryView
As you see on the left side (white background), I want to hide/remove this area. I tried to do many things but doesn’t work. I just want to use right area.
How can I do that?
I was stucked too for a while , but eventually found:
mkAnnotationView.leftCalloutAccessoryView.isHidden = true
Might be a silly question but have you tried just doing
mkAnnotationView.leftCalloutAccessoryView = nil

I have two UIButtons and a strange rectangle appears when tapping one of them. I don't know why. I set the images as background images on the button and it worked fine until now.
What I changed now is that I set each button isSelected property and before I did not
Like this:
thumbsDownButton.isSelected = true
thumbsUpButton.isSelected = false
Obviously what I want is for that rectangle to go away
The style was set to System. Setting it to Custom fixed the problem and the rectangle is not appearing anymore. I set it from the xib (if it makes any difference)
Add this Code
thumbsDownButton.tintColor = UIColor.white
It seems your frame may be calculated in the wrong way.
Try to use this one to check it.
button.clipToBounds = true
Please share more code related of initializing and setting up the frame of your view.
I have a custom class here that consists of a UIButton inside of a UIView.
The goal of this class is to allow users to have a greater area (being the UIView) to select the button than just the buttons frame itself.
Now when a user taps on the view I want the buttons highlighted image to show... But the problem is, it does not.
I've read many possible solutions to this issue For Example:
Calling: [btnObject sendActionsForControlEvents:UIControlEventTouchUpInside]
This however did not change the buttons highlight.
I also tried just settings the button.highlighted = YES;
But that did not work either.
I have the images for different states properly setup (Normal and Highlighted), I'm sure of that.
I also have the gestureRecognizer working properly as the functionality is great except for the lack of highlight.
Does anybody know if I'm missing any thing special that needs to be done in order to pull off this seemingly very simple task? Surely it's been done many times.
Thank you
You were on the right track. -[UIButton setHighlighted:] is just a flag. What you need to do is call setNeedsDisplay on that button right after you change the highlighted property.
I solved my problem a little while ago and I'm not sure if Kevin Low's answer would've worked too, it very well might have.
But for some reason, a UITapGesture doesn't work well with highlighting buttons as a view transitions (That might be because I didn't call setNeedsDisplay). The gesture that ended up working was the UILongPressGesture with a 0.0 sec for minimum duration.
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 want to create a set of buttons that will look like this:
(The selected buttons are those with a different background)
Any ideas for a simple implementation?
Are there any known open source implementations for this?
Thanks!
Following is the library which may be use to solve your problem,
For different appearance you need to give the conditional code for that but with out that your problem may solve with this library or code.
You can download the sample code of RRTagController project here.
For rounded corners use UIButton.layer.cornerRadius. if you set corner radius to half of the box you will get circle. For the border color use layer.borderColor = UIColor.redColor().CGColor.
For the background color of the button you can keep track with selected state of the button. Here is an example of using selected state: UIButton state selected
Next thing you could do is to keep data about selected ones, since the best way to do something like this would be UITableView - seems like every row of buttons have same height, and if you want to send that somewhere you can keep track about what items are selected.
I think the best way is to use UICollectionView.
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.
