UIButton image in NavigationItem - ios

please tell me. I am trying to assign UIButton to titleView from navigationItem with an inscription and image. The inscription appears normal, but the image does not appear, and the indentation has under it (the inscription is shifted to the right from the center)
UIButton* openMenu = [UIButton buttonWithType:UIButtonTypeCustom];
[openMenu addTarget:self action:#selector(openCloseMenuAction:) forControlEvents:UIControlEventTouchUpInside];
[openMenu setTitle:#"title" forState:UIControlStateNormal];
[openMenu setImage:[UIImage imageNamed:#"downButton.png"] forState:UIControlStateNormal];
self.navigationController.navigationBar.topItem.titleView = openMenu;

It looks to me like you need to give openMenu a size. You could try [openMenu sizeToFit] and see how that looks.

Use imageEdgeInset and titleEdgeInset properties of UIButton to position title and image inside of a button.
Set frame of your UIButton
titleButton.frame = CGRectMake(0, 0, 200, 44);
Assign the title view in view controllers viewDidLoad: method using
self.navigationItem.titleView = titleButton;

It's hard to click on Bar button Item

I've created custom back bar button. And I added an UIview because I have to change position of it within bar.
UIImage *backButtonImage = [UIImage imageNamed:#"backBtnWhite"];
_backButton = [UIButton buttonWithType:UIButtonTypeCustom];
_backButton.exclusiveTouch = YES;
[_backButton setImage:backButtonImage forState:UIControlStateNormal];
[_backButton setImage:backButtonImage forState:UIControlStateHighlighted];
[_backButton addTarget:self action:#selector(back) forControlEvents:UIControlEventTouchUpInside];
_backButton.frame = CGRectMake(-4.0, 7.0, 40, 40);
UIView * view = [[UIView alloc] initWithFrame:CGRectMake(-4.0, 7.0, backButtonImage.size.width, backButtonImage.size.height)];
[view addSubview:_backButton];
UIBarButtonItem* barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];
self.navigationItem.rightBarButtonItem = barButtonItem;
But after that I've added UIView it became difficult to click on it.
I've tried to change button area, but it didn't give results.
It seems like you specify incorrect frame for _button or/and view and this changes the tap region. Try to set different background color for _backButton and view. This will show you if frames are in positions that you expect.
If you try to adjust image position by specifying these frames - its more correct to use properties of UIButton like imageEdgeInsets and titleEdgeInsets.

UITool bar button with image and dynamic text "Below" it

I want to implement a Button on the UIToolbar with "Image" On Top and Text below it as shown below.
I have used the following code:
UIButton* customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setImage:[UIImage imageNamed:#"search2.png"] forState:UIControlStateNormal];
[customButton setTitle:#"Categorie" forState:UIControlStateNormal];
[customButton sizeToFit];
UIBarButtonItem* cataBtn = [[UIBarButtonItem alloc] initWithCustomView:customButton];initWithCustomView:customButton];
cataBtn
But it shows the result as follows:
How should i customize it in such a way that the Image is On top and Text Below it ?
I dont want to use a single image with both picture and text, since the text is a dynamically changing one.
You need to set the edge insets
customButton.titleEdgeInsets = UIEdgeInsetsMake(0, -60, -30, 0);
customButton.imageEdgeInsets = UIEdgeInsetsMake(-15, 0 , 0, 0); // give some space for text

Make custom Navigation Buttons glow when touched?

In my navigation bar I have two right button bar items. One is a custom button and the other uses the info light button type. Both work great but I would like to make the custom button have the default glow the same way the info button does when you touch it. Is this possible?
// Default info light btn
UIButton *infoBtn = [UIButton buttonWithType:UIButtonTypeInfoLight];
UIBarButtonItem *infoBtnItem = [[UIBarButtonItem alloc]initWithCustomView:infoBtn];
// Custom Btn
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setFrame:CGRectMake(0, 0, btnImage.size.width, btnImage.size.height)];
[customButton setBackgroundImage:btnImage forState:UIControlStateNormal];
[customButton addTarget:self action:#selector(rightDrawerButtonPress:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *customButtonItem = [[UIBarButtonItem alloc] initWithCustomView:wlButton];
NSArray *rightBtns = #[customButtonItem, infoBtnItem];
[navItem setRightBarButtonItems:rightBtns animated:YES];
you just need to put one more line of code like:-
customButton.showsTouchWhenHighlighted = TRUE;
After this your code Output something like this:-

UIButton Image + Text IOS

I need a UIButton with image & text. Image should be in the top & text comes under the image both should be clickable.
I see very complicated answers, all of them using code. However, if you are using Interface Builder, there is a very easy way to do this:
Select the button and set a title and an image. Note that if you set the background instead of the image then the image will be resized if it is smaller than the button.
Set the position of both items by changing the edge and insets. You could even control the alignment of both in the Control section.
You could even use the same approach by code, without creating UILabels and UIImages inside as other solutions proposed. Always Keep It Simple!
EDIT: Attached a small example having the 3 things set (title, image and background) with correct insets
I think you are looking for this solution for your problem:
UIButton *_button = [UIButton buttonWithType:UIButtonTypeCustom];
[_button setFrame:CGRectMake(0.f, 0.f, 128.f, 128.f)]; // SET the values for your wishes
[_button setCenter:CGPointMake(128.f, 128.f)]; // SET the values for your wishes
[_button setClipsToBounds:false];
[_button setBackgroundImage:[UIImage imageNamed:#"jquery-mobile-icon.png"] forState:UIControlStateNormal]; // SET the image name for your wishes
[_button setTitle:#"Button" forState:UIControlStateNormal];
[_button.titleLabel setFont:[UIFont systemFontOfSize:24.f]];
[_button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; // SET the colour for your wishes
[_button setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted]; // SET the colour for your wishes
[_button setTitleEdgeInsets:UIEdgeInsetsMake(0.f, 0.f, -110.f, 0.f)]; // SET the values for your wishes
[_button addTarget:self action:#selector(buttonTouchedUpInside:) forControlEvents:UIControlEventTouchUpInside]; // you can ADD the action to the button as well like
...the rest of the customisation of the button is your duty now, and don't forget to add the button to your view.
UPDATE #1 and UPDATE #2
or, if you don't need a dynamic button you could add your button to your view in the Interface Builder and you could set the same values at there as well. it is pretty same, but here is this version as well in one simple picture.
you can also see the final result in the Interface Builder as it is on the screenshot.
Xcode-9 and Xcode-10 Apple done few changes regarding Edge Inset now, you can change it under size-inspector.
Please follow below steps:
Step-1:
Input text and select image which you want to show:
Step-2:
Select button control as per your requirement as shown in below image:
Step-3:
Now go-to size inspector and add value as per your requirement:
swift version:
var button = UIButton()
newGameButton.setTitle("Новая игра", for: .normal)
newGameButton.setImage(UIImage(named: "energi"), for: .normal)
newGameButton.backgroundColor = .blue
newGameButton.imageEdgeInsets.left = -50
In my case, I wanted to add UIImage to the right and UILabel to the left. Maybe I can achieve that by writing code (like the above mentioned), but I prefer not to write code and get it done by using the storyboard as much as possible. So this is how did it:
First, write down something in your label box and select an image that you want to show:
And that will create a button looking like this:
Next, look for Semantic and select Force Right-to-Left (If you don't specify anything, then it will show the image to the left and label to the right like the above image):
Finally, you'll see UIImage to the right and UILabel to the left:
To add space between a label and an image, go to the Size inspector and change those values depending on your requirement:
That's it!
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.imageView.image = [UIImage imageNamed:#"your image name here"];
button.titleLabel.text = #"your text here";
but following code will show label above and image in background
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.background.image = [UIImage imageNamed:#"your image name here"];
button.titleLabel.text = #"your text here";
There is no need to use label and button in same control because UIButton has UILabel and UIimageview properties.
Use this code:
UIButton *sampleButton = [UIButton buttonWithType:UIButtonTypeCustom];
[sampleButton setFrame:CGRectMake(0, 10, 200, 52)];
[sampleButton setTitle:#"Button Title" forState:UIControlStateNormal];
[sampleButton setFont:[UIFont boldSystemFontOfSize:20]];
[sampleButton setBackgroundImage:[[UIImage imageNamed:#"redButton.png"]
stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal];
[sampleButton addTarget:self action:#selector(buttonPressed)
forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:sampleButton]
You should create custom imageview for image and custom label for text and you add to your button as subviews. That's it.
UIButton *yourButton = [UIButton buttonWithType:UIButtonTypeCustom];
yourButton.backgroundColor = [UIColor greenColor];
yourButton.frame = CGRectMake(140, 40, 175, 30);
[yourButton addTarget:self action:#selector(yourButtonSelected:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:yourButton];
UIImageView *imageView1 = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, yourButton.frame.size.width, yourButton.frame.size.height/2)];
imageView1.image =[UIImage imageNamed:#"images.jpg"];
[yourButton addSubview:imageView1];
UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(0, yourButton.frame.size.height/2, yourButton.frame.size.width, yourButton.frame.size.height/2)];
label.backgroundColor = [UIColor greenColor];
label.textAlignment= UITextAlignmentCenter;
label.text = #"ButtonTitle";
[yourButton addSubview:label];
For testing purpose, use yourButtonSelected: method
-(void)yourButtonSelected:(id)sender{
NSLog(#"Your Button Selected");
}
I think it will be helpful to you.
Use this code:
UIButton *button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
button.imageView.frame=CGRectMake(0.0f, 0.0f, 50.0f, 44.0f);///You can replace it with your own dimensions.
UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(0.0f, 35.0f, 50.0f, 44.0f)];///You can replace it with your own dimensions.
[button addSubview:label];
I encountered the same problem, and I fix it by creating a new subclass of UIButton and overriding the layoutSubviews: method as below :
-(void)layoutSubviews {
[super layoutSubviews];
// Center image
CGPoint center = self.imageView.center;
center.x = self.frame.size.width/2;
center.y = self.imageView.frame.size.height/2;
self.imageView.center = center;
//Center text
CGRect newFrame = [self titleLabel].frame;
newFrame.origin.x = 0;
newFrame.origin.y = self.imageView.frame.size.height + 5;
newFrame.size.width = self.frame.size.width;
self.titleLabel.frame = newFrame;
self.titleLabel.textAlignment = UITextAlignmentCenter;
}
I think that the Angel García Olloqui's answer is another good solution, if you place all of them manually with interface builder but I'll keep my solution since I don't have to modify the content insets for each of my button.
Make UIImageView and UILabel, and set image and text to both of this....then Place a custom button over imageView and Label....
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"search.png"]];
imageView.frame = CGRectMake(x, y, imageView.frame.size.width, imageView.frame.size.height);
[self.view addSubview:imageView];
UILabel *yourLabel = [[UILabel alloc] initWithFrame:CGRectMake(x, y,a,b)];
yourLabel.text = #"raj";
[self.view addSubview:yourLabel];
UIButton * yourBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[yourBtn setFrame:CGRectMake(x, y,c,d)];
[yourBtn addTarget:self action:#selector(#"Your Action") forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:yourBtn];
It's really simple,just add image to background of you button and give text to titlelabel of button for uicontrolstatenormal.
That's it.
[btn setBackgroundImage:[UIImage imageNamed:#"img.png"] forState:UIControlStateNormal];
[btn setContentVerticalAlignment:UIControlContentVerticalAlignmentBottom];
[btn setTitle:#"Click Me" forState:UIControlStateNormal];

How to force button to stay at tableView cell's bottom?

I add a button as a subview to my tableviewcells. Works fine. But I can't seem to figure out, how to force it to always be at the bottom of the cell. (On top of the separator line if you will). The cell height varies, so a fixed position is not smart. But I have no clue how to add it with a dynamic position. Here's the code for adding the button:
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self
action:#selector(buttonPressed:)
forControlEvents:UIControlEventTouchDown];
[button setTitle:#"+1" forState:UIControlStateNormal];
button.frame = CGRectMake(0.0f, 70.0f, 160.0f, 15.0f);
[cell addSubview:button];
Set the autoresizing mask when adding the button. I think the setting you want is:
button.autoresizingMask = UIViewAutoResizingFlexibleTopMargin;
Do this after adding the button to the cell.
You can always check the height of the cell and put the button's frame like this.
button.frame=CGRectMake(0,cellHeight-15,160,15);
