I put some view the UIButton object and set the image to the button using setImage:forState: method.
the image size is 19x8.
And, called [button setTranslatesAutoresizingMaskIntoConstraints:NO] method to adjust Autolayout. The autolayout is only setting position of button.
then, I found out the button size is 19x22 and the enclosed image size is 19x8. The image position is center vertically.
Why the button is not same to the image?
How can I make them to same size?
I added the sample code.
UIButton *button = [[UIButton alloc] initWithFame:CGRectZero];
[button setImage:[UIImage imageNamed:#"buttonImage"] forState:UIControlStateNormal]];
[button setTranslatesAutoresizingMaskIntoConstraints:NO];
That's it.
If you want the button to be of same size as the image then,first get the size of the image.
CGFloat width = myImage.size.width;
CGFloat height = myImage.size.height;
CGRect myRect = CGSizeMake:(myButton.frame.size.x,myButton.frame.size.y,width,height); //x and y with respect with superview.
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.frame = myRect;
I'm trying to add my settings button to my toolbar but the frame I have to set for it is altering the image dimensions. How do i set the frame without messing with the image itself. The image is stored in an asset catalog for #1x, #2x, and #3x.
-(void)viewWillAppear:(BOOL)animated{
//Toolbar buttons
UIView *buttonContainer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
buttonContainer.backgroundColor = [UIColor clearColor];
UIButton *button0 = [UIButton buttonWithType:UIButtonTypeCustom];
--[button0 setFrame:CGRectMake(0, 0, 44, 44)];-------------
[button0 setBackgroundImage:[UIImage imageNamed:#"settings-128(1).png"] forState:UIControlStateNormal];
[button0 addTarget:self action:#selector(button0Action:) forControlEvents:UIControlEventTouchUpInside];
[button0 setShowsTouchWhenHighlighted:YES];
[buttonContainer addSubview:button0];
self.navigationItem.titleView = buttonContainer;
}
You have a few different options. If you don't absolutely need to make your button a different size than its background image, then you can set the background image and then get a size that will not stretch that background image, to assign to the button's frame, like:
[button0 setBackgroundImage:[UIImage imageNamed:#"settings-128(1).png"] forState:UIControlStateNormal];
const CGSize button0Size = [button0 sizeThatFits:CGSizeZero];
[button0 setFrame:CGRectMake(0, 0, button0Size.width, button0Size.height)];
If you actually want to change the size of your background image without distortion (for example, you might want to elongate the background image by copying pixels in its center) you should look into the resizableImageWithCapInsets: methods provided by UIImage.
If for some reason you need button0 to have a particular frame and you want its background to be a different size, you can subclass UIButton and in your subclass explicitly implement:
- (CGRect)backgroundRectForBounds:(CGRect)bounds
and return a correctly sized frame for your background image regardless of the button's bounds.
And of course, if all else fails, you can pad your asset settings-128(1).png with clear pixels to make the image size match the desired frame size. I don't recommend that approach if you can avoid it since it will cause any future changes to the button's size to require careful changes to the image (and the 2x and 3x versions of the image).
I have a cell that has some text in it and was trying to add an image to the cell.
This is what Ive tried:
UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(30, 30, 30, 30)];
imageView.backgroundColor = [UIColor clearColor];
[imageView.layer setCornerRadius:5.0f];
[imageView.layer setMasksToBounds:YES];
[imageView setImage:[UIImage imageNamed:#"test2.jpeg"]];
[cell.contentView addSubview:imageView];
cell.imageView.clipsToBounds = YES;
This is what it looks like right now:
Is there a way to avoid the image from overlapping the text in the cell? Thanks in advance!
tableviewcells have their own imageView that will appear to the left of the content or atleast to the left of the cells text.
You are creating an extra imageView that just happens to have the same name.
Just change the location
cell.imageView.center = CGPointMake(x,y);
Check out https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/TableView_iPhone/TableViewCells/TableViewCells.html#//apple_ref/doc/uid/TP40007451-CH7-SW11 which has a nice example of how to use the built-in UITableViewCell image view.
Every UITableViewCell already has an UIImageView property 'imageView', but it's only shown if you set the imageView properties image property (cell.imageView.image = /* image code */;)
The best thing you can do is create a custom UITableViewCell. Or perhaps add another UILabel to the current cell and set your text in that instead of using the default UILabel.
is it possible to increase tapable area of UIButton without changing size of Button's background Image
I tried:
[shareButton setContentEdgeInsets:UIEdgeInsetsMake(top, left, bottom, right)];
&
[shareButton setImageEdgeInsets:UIEdgeInsetsMake(top, left, bottom, right)];
but none of these worked.
Any Suggestion please?
Make the UIButton of type buttonWithType:UIButtonTypeCustom and assign to it an image of a smaller size.
Do not set the image as the background image or it'll grow with the button. Set it as the main image instead.
For example if you want to set the tappable area to a 64x64 size and you want to show an image sized 32x32: the button size should be be 64x64 and the image size should be 32x32.
Programmatically:
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
// use an image with the desired size (for example 32x32)
[button setImage: [UIImage imageNamed: #"buttonIcon.png"] forState: UIControlStateNormal];
// just set the frame of the button (64x64)
[button setFrame: CGRectMake(xPositionOfMyButton, yPositionOfMyButton, 64, 64)];
Interface Builder:
Subclass the superview of the UIButton, and override hitTest:withEvent:
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
CGPoint buttonPoint = [self convertPoint:point toView:_button];
if ([_button pointInside:buttonPoint withEvent:event]) { // you may add your requirement here
return _button;
}
return [super hitTest:point withEvent:event];
}
Use the design approach you like (Interface Builder / Visual Format Language) together with Autolayout and layout the UIButton with the required size. Set title or image as content and use a transparent image with the size of the tapable area as background image.
_button = [UIButton buttonWithType:UIButtonTypeCustom];
[_button setImage:[UIImage imageNamed:#"contentImage"] forState:UIControlStateNormal];
[_button setBackgroundImage:[UIImage imageNamed:#"transparentImage"] forState:UIControlStateNormal];
Here a example with _button.layer.borderWidth = 1.
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];
