I need to add image in Action sheet item using UIAlertController. I add using:
UIImage *image = [UIImage imageNamed:#"icon.png"];
[alertAction setValue:image forKey:#"image"];
And results as:
The problem is that:
I need the image & text to be centrally aligned and resize the height of Cancel button
How can i do that, please share some code.
Thanks!
Well, here is the Runtime Header file for UIAlertAction. You can neither change the frame of image nor you can change the height of Cancel button.
So what is the solution?
The only solution that I could figure is to make a custom view with UIVisualEffect and show/animate it like UIActionSheet. Basically you need to imitate UIActionSheet.
That said, I would like to welcome other solutions as well.

I searched all the topics about backbarbutton custom, but seems failed to find answers about my problem on backbarbutton.
To keep the property called interactivePopGestureRecognizer of UINavigationController, using leftBarButton to replace backBarButton is not a valid solution. But I want to custom the backbarbutton with a image, so I use the following code in my controller ViewDidLoad:
UIBarButtonItem * btnBack = [[UIBarButtonItem alloc]init];
btnBack.title = #"";
self.navigationController.navigationBar.backIndicatorImage = [UIImage imageNamed:#"backBtn"];
self.navigationController.navigationBar.backIndicatorTransitionMaskImage = [UIImage imageNamed:#"backBtn"];
self.navigationItem.backBarButtonItem = btnBack;
when I run my project, it shows just a blue rectangle in the place where backBarButton always show.
But the original image just like the system barbutton that called reply.
However, it has a different effect, just change to the image named "Drinks" which is a black image that show a glass of juice.
after run my project the place where always show backBarButton show a blue image just like "Drinks".
what happend! How can I custom my backBarButton with the giving image named backBtn.png, is there anyone can help me? Thanks in advance! For image submit has been reject, I discrible my problem in words.
The Image has be transparent where there should be nothing to be drawn. It should be opaque where the content of the image will be drawn. At least that worked for me. The final color will be tinted by the navigationbar's tintColor anyway.
I need to show an image, and above it some buttons that correspond to certain clickable areas of the image, the problem is that the image has zoom, and when i zoom the image, the buttons do not stay in the same place as the picture. The solution was to use the class ImageScrolView, used in the example of Apple PhotoScroller. The button appears exactly in the right place, regardless of zoom.
Just like the example, i use a ScrollView to display multiple images, these images are shown by class ImageScrollView.
This class declares one UIView in the .H file, but in the implementation file, the method that displays the image, convert the UIView into a UIImageView
imageView = [[UIImageView alloc] initWithImage: image];
then create my button and add to the imageView.
amazon = [UIButton buttonWithType: UIButtonTypeRoundedRect];
amazonia.frame = CGRectMake (92,240,109,142);
[amazon addTarget: self action: # selector (selectState :) forControlEvents: UIControlEventTouchUpInside];
[imageView addSubview: amazon];
My problem is that the button does not respond to button events, it appears in the right place and everything, but does not respond to button events.
Any ideas? Ideias on how to implement those clickable areas on the image are welcome too.
make sure to set imageView.userInteractionEnabled = YES!
Hope that helps.
Hi I want to change the background of my button after I press the button i.e. the button should not change back to the previous image.
However, I am not able to do so. My code as follows. Can anyone advise how I can change the image to "custom_button_highlight" after I click on the button?
UIImage *buttonImageNormal = [UIImage imageNamed:#"custom_button"];
UIImage *stretchableButtonImageNormal = [buttonImageNormal
stretchableImageWithLeftCapWidth:12 topCapHeight:0];
UIImage *buttonImagePressed = [UIImage imageNamed:#"custom_button_highlight"];
UIImage *stretchableButtonImagePressed = [buttonImagePressed
stretchableImageWithLeftCapWidth:12 topCapHeight:0];
button.titleLabel.font = [UIFont boldSystemFontOfSize:14];
[button setBackgroundImage:stretchableButtonImageNormal
forState:UIControlStateNormal];
[button setBackgroundImage:stretchableButtonImagePressed
forState:UIControlStateHighlighted];
[button setBackgroundImage:stretchableButtonImagePressed
forState:UIControlStateSelected];
METHOD1
I see that you are using code to generate UIButton. It's easier to use Interface builder. Try this - In Interface builder (Xcode4), create the button & open the right sidebar. After that select the button, & the type of button as custom. After that in state config, there are various states, for each state you can set an image in image. Hope this helps...
METHOD2
If you want to use code to generate UIButton (it beats me why) then you seem to be doing the right thing. Are you sure the images are there in your bundle? You did not include the image extension (like .jpg etc.)
You mentioned, that you don't want the image to change back...
then instead of setting it for the states highlighted or selected, you have to set it for the state UIControlStateNormal.
But since you need it after it's been pressed, you have to catch the event that your button has been pressed and set the background image in there.
Hope it helped ;)
[_buttonConfirm setImage:[UIImage imageNamed:#"s.png"] forState:UIControlStateSelected ];
... does what you want programatically, not the background image. But I think you should follow Srikar's answer and use interface builder if you can.
I have some uiButtons in my table view and i want to load them with images which i get from an array. But i am not able to add images to the button using the array and it is crashing my entire app. Can anyone provide me the solution of how to add images to buttons in table view using Array of Images.Any help will be appreciated.
This method is called from a loop where i am passing a button as the parameter
-(void)setImage1:(UIButton *)button
UIButton *newButton=[[UIButton alloc]init];
newButton=button;
[newButton setImage:[NSString stringWithFormat:#"%d.png", j] forState:UIControlStateNormal]; j++; }
Thanks,
Christy
//Create an image
UIImage *image= [UIImage imageWithContentsOfFile:#"image.jpg"];
// Set image for the button
[button setBackgroundImage:image forState:UIControlStateNormal];
Show us some code at least for more help.
You should not create the button within that method. Create it in ViewDidLoad, or even better, in Interface builder. If you create a button programatically you will have to also make sure you enable user interaction, and then set its frame and add it to the view.
