Add text to a custom Back Button iOS - ios

I have a backbutton with an image I'm using in my navigation controller, and I'd like to set the text over top of the image. I tried this but it doesn't seem to show up:
UIImage *normalBackImage = [UIImage imageNamed:#"button_tl.png"];
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom]; backButton.bounds = CGRectMake(0, 0, normalBackImage.size.width, normalBackImage.size.height );
[backButton setImage:normalBackImage forState:UIControlStateNormal];
backButton.titleLabel.text = #"Back";
Does anyone know how to accomplish this? Thanks!

set the title's color, else you'll not see anything :)
setTitleColor:forState:
2.
dont try to set the image (which means FOREGROUND image). Instead set the BACKGROUND image :)
– setBackgroundImage:forState:
sample:
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
backButton.frame = CGRectMake(10, 10, 100, 50);
[backButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[backButton setTitle:#"Bla" forState:UIControlStateNormal];
UIImage *normalBackImage = [UIImage imageNamed:#"button_tl.png"];
[backButton setBackgroundImage:normalBackImage forState:UIControlStateNormal];
[self.view addSubview:backButton];

You could create a UILabel and add it as a subview to your UIImage. That would look something like this (writing code outside the compiler, might not be perfect)
UILabel *myLabel = [[UILabel alloc] init];
[myLabel setText:#"My Label Text"];
[image addSubview:myLabel];

How to show the title under the UIButton?

I have used the title inset to display the text name under the UIButton.
Here's my code and the output:
[button setTitleEdgeInsets:UIEdgeInsetsMake(60, 0, 0, 0)];
Here's my expected output:
I have used the UIButton and set the title and UIImage as background. So how to show the title label under the UIButton?
What you're trying to do is correct; you just need to set the inset edges as done below. Then you need to increase your button frame so that it can hold the title and image in the same time.
[button setTitleEdgeInsets:UIEdgeInsetsMake(60, 0, 0, 0)];
[button setImageEdgeInsets:UIEdgeInsetsMake(0.0f, 0.f, button.titleLabel.frame.size.height, 0.f)];
This can also be done via storyboards as #VD Patel suggests that is up to you which approach you prefer.
You could also do this with a separate UIImageview and a button that would be easier to handle and would be more efficient.
Please Select button in xib first. then select Attribute Inspector, in this Select Title in "Edge" and set appropriate "Inset" as per Requirements.
please take a look with below code and set insets as per your Requirements.
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
myButton.frame = CGRectMake(0, 0, self.view.bounds.size.width, 40);
[myButton setImage:[UIImage imageNamed:#"imageName"] forState:UIControlStateNormal];
[myButton setTitle:#"Rate us on app store" forState:UIControlStateNormal];
[myButton setTitleEdgeInsets:UIEdgeInsetsMake(2, 50, 2, 20)];//set ur title insects myButton
[myButton setImageEdgeInsets:UIEdgeInsetsMake(2, -200, 2, 2)];//make negative edge for left side
[myButton setBackgroundColor:[UIColor greenColor]];
[self.view myButton];
Create an UIImageView,UILabel and UIButton. And later add ImageView and Label as subview to Button.
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 200, 200, 100)];
lbl.textAlignment = NSTextAlignmentCenter;
[lbl setText:#"Mono"];
UIImageView * imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
imgView.image = [UIImage imageNamed:#"your_image.png"];
[imgView setUserInteractionEnabled:NO];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn addSubview:imgView];
[btn addSubview:lbl];
[btn setFrame:CGRectMake(0, 20, 200, 300)];
[btn addTarget:self action:#selector(OnButtonClick:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
Try adding this code in viewDidLoad Method.

Custom UIBarButtonItem keep Aspect Ratio for Image but Space out Buttons

I am adding some custom image UIBarButtonItems to my navigation bar. If I do not mess with the item.width property, then my buttons are too close together, but if I space them out with the width property, then the button image is distorted. How can I maintain the aspect ratio of the button image but space out my custom items?
// Create custom map button
UIButton *mapButton = [UIButton buttonWithType:UIButtonTypeCustom];
[mapButton setImage:[UIImage imageNamed:#"map.png"] forState:UIControlStateNormal];
[mapButton addTarget:self action:#selector(dismissMapView:) forControlEvents:UIControlEventTouchUpInside];
[mapButton setFrame:CGRectMake(280, 25, 30, 30)];
UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithCustomView:mapButton];
button1.width = (self.drawer.frame.size.width / 5.0f); // Space it out a bit
// Create custom list button
UIButton *listButton = [UIButton buttonWithType:UIButtonTypeCustom];
[listButton setImage:[UIImage imageNamed:#"list.png"] forState:UIControlStateNormal];
[listButton addTarget:self action:#selector(scrollToRow:) forControlEvents:UIControlEventTouchUpInside];
[listButton setFrame:CGRectMake(280, 25, 30, 30)];
UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithCustomView:listButton];
button2.width = (self.drawer.frame.size.width / 5.0f); // Space it out a bit
// Add buttons to drawer
self.drawer.items = #[button1,button2];
Try this code for adding custom bar button in navigationbar.
UIImage* image3 = [UIImage imageNamed:#"compose_message_button.png"];
CGRect frameimg = CGRectMake(250, 9, 43,32);
UIButton *SettingButton = [[UIButton alloc] initWithFrame:frameimg];
[SettingButton setBackgroundImage:image3 forState:UIControlStateNormal];
[SettingButton addTarget:self action:#selector(BtnWriteMessage:)
forControlEvents:UIControlEventTouchUpInside];
[SettingButton setShowsTouchWhenHighlighted:YES];
UIBarButtonItem *mailbutton =[[UIBarButtonItem alloc] initWithCustomView:SettingButton];
self.navigationItem.rightBarButtonItem=mailbutton;
[SettingButton release];
i hope this code is useful for you.
You can create some explicit spacer items using UIBarButtonSystemItemFixedSpace.
Or you could create your bar buttons with custom views (initWithCustomView:) and then you can lay the content views out as you like.

Add a back arrow to leftBarButtonItem?

I want to add a back arrow to a leftBarButtonItem, to make it appear visually as if it was a regular back button, although it's functionality is slightly different.
Is there a way to do this?
You can use custom button and hide the back button if you are using navigation controller.
To hide back button use this:
self.navigationItem.hidesBackButton = YES;
And for Custom Button:
UIButton * customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setBackgroundColor:[UIColor colorWithRed:197.0/255.0 green:190.0/255.0 blue:157.0/255.0 alpha:1.0]];
[customButton setTitle:#"Do Something" forState:UIControlStateNormal];
customButton.titleLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:11.0f];
[customButton.layer setCornerRadius:3.0f];
[customButton.layer setMasksToBounds:YES];
[customButton.layer setBorderWidth:1.0f];
[customButton.layer setBorderColor: [[UIColor grayColor] CGColor]];
customButton.frame=CGRectMake(0.0, 100.0, 50.0, 25.0);
[customButton addTarget:self action:#selector(customMethod:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem * customItem = [[UIBarButtonItem alloc] initWithCustomView:customButton];
customItem.tintColor=[UIColor blackColor];
self.navigationItem.leftBarButtonItem = customItem;
This will work for you.
Happy Coding
If you are using UINavigationController and then push new viewcontroller it will automatically show back button.
If you are Not Using UINavigationController than
Use Custom UIButton for that with back image
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
backButton.frame = CGRectMake(0, 0, 48, 37);
[backButton addTarget:self action:#selector(backButtonTapped) forControlEvents:UIControlEventTouchUpInside];
backButton.showsTouchWhenHighlighted = YES;
UIImage *backButtonImage = [UIImage imageNamed:#"back-button.png"];
[backButton setImage:backButtonImage forState:UIControlStateNormal];
backButton.imageEdgeInsets = UIEdgeInsetsMake(10, 10, 10, 10);
UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem = backBarButtonItem;
You can change the value for the frame and the imageEdgeInsets as per your requirements.

iOS: How to cover entire button with image

I am currently working on a iOS application where I am constantly changing the pictures of two buttons. The problem is that the picture of the button that constantly changes does not stretch over the entire button. I was wondering what is the best way of doing this.
I believe I am setting my image of my button normally and I cant figure out what to do. Any suggestions will be greatly appreciated.
leftButton setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:#"%#", [orangeImageArray objectAtIndex:randomPicture2]]] forState:UIControlStateNormal];
Is your button type UIButtonTypeCustom ?
example :
UIButton *leftButton = [UIButton buttonWithType:UIButtonTypeCustom];
[leftButton setImage:btnImage forState:UIControlStateNormal];
Try this:
UIImage *btnImage = [UIImage imageNamed:#"image.png"];
[leftButton setImage:btnImage forState:UIControlStateNormal];
This code enables you to customize the button well:
UIImage *img = [UIImage imageNamed:#"icon.png"];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.bounds = CGRectMake(0, 0, img.size.width, img.size.height);
[btn setBackgroundImage:img forState:UIControlStateNormal];
[btn addTarget:self action:#selector(prefer) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:btn];
self.navigationItem.rightBarButtonItem = barButton;

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];
