I need to draw a circle like border outside UIButton. Below is the attach image and code. I also need to show text below button. Following code will add image and text beneath that. But how do I have layer.
UIButton *imageButton = [UIButton buttonWithType:UIButtonTypeCustom];
[imageButton setBackgroundImage:image forState:UIControlStateNormal];
imageButton.translatesAutoresizingMaskIntoConstraints = NO;
imageButton.backgroundColor = [UIColor clearColor];
[imageButton setTitle:title forState:UIControlStateNormal];
imageButton.titleLabel.textAlignment = NSTextAlignmentCenter;
imageButton.titleLabel.font = [UIFont fontWithName:#"OpenSans" size:fon];
[imageButton setTitleEdgeInsets:UIEdgeInsetsMake(95, 0.0f, 0.0f, 0.0f)];
[imageButton setTitleColor:[UIColor iconTextColor] forState:UIControlStateNormal];
[imageButton addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
set the button width and height ex : width =100 and height = 100, should be same if you want a round then,
imageButton.layer.cornerRadius = 50 // this value should be half from width or height (width = height)
imageButton.layer.masksToBounds = YES
//if you want border with above
imageButton.layer.borderWidth = 1;
imageButton.layer.borderColor = [[UIColor blackColor] CGColor];
You can do something like this.
borderView = UIView()
yourButton = UIButton()
borderView.frame.size.width = yourButton.frame.size.width + 1
borderView.layer.cornerRadius = borderView.frame.size.width/2
borderView.clipToBounds = true
borderView.backgroundColor = UIColor.clearColor()
borderView.layer.borderWidth = 1
borderView.layer.borderColor = UIColor.blueColor()

I created a UIButton programmatically and set its image, but the image just won't center vertically, it's always rendered at the bottom of the button.
Here is my code:
CGFloat logoutButtonSize = self.profileItem.detailView.frame.size.height;
CGFloat logoutButtonX = self.profileItem.detailView.frame.size.width - logoutButtonSize - 8;
CGRect logoutButtonFrame = CGRectMake(logoutButtonX, 0, logoutButtonSize, logoutButtonSize);
UIButton *logoutButton = [[UIButton alloc] initWithFrame:logoutButtonFrame];
[logoutButton setImage:[UIImage imageNamed:#"logout.png"] forState:UIControlStateNormal];
logoutButton.imageView.contentMode = UIViewContentModeCenter;
logoutButton.contentMode = UIViewContentModeCenter;
[logoutButton addTarget:self
action:#selector(confirmLogout)
forControlEvents:UIControlEventTouchUpInside];
logoutButton.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
logoutButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
logoutButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
After setting a distinct background color for the imageView of the button I can see that it's still aligned to the bottom:
(blue = button, red = image view)
Why is it not working?
Based on your posted image, it looks like the Button itself is being clipped at the bottom, as opposed to the image not being centered vertically.
Your code:
CGRect logoutButtonFrame = CGRectMake(logoutButtonX, 0, logoutButtonSize, logoutButtonSize);
says the Button (blue rectangle) should be square. Yet in the image you posted, the blue rectangle is 120 x 88.
The bottom portion of your button is not being displayed, so it looks like your image is not centered.
By the way, you shouldn't need much of the code you are using:
// define the frame size
CGFloat logoutButtonSize = self.profileItem.detailView.frame.size.height;
CGFloat logoutButtonX = self.profileItem.detailView.frame.size.width - logoutButtonSize - 8;
CGRect logoutButtonFrame = CGRectMake(logoutButtonX, 0, logoutButtonSize, logoutButtonSize);
// instantiate the UIButton
UIButton *logoutButton = [[UIButton alloc] initWithFrame:logoutButtonFrame];
// set the image
[logoutButton setImage:[UIImage imageNamed:#"logout.png"] forState:UIControlStateNormal];
// add the button action target
[logoutButton addTarget:self
action:#selector(confirmLogout)
forControlEvents:UIControlEventTouchUpInside];
// set the resizing mask properties
logoutButton.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
// shouldn't need any of the following
//logoutButton.imageView.contentMode = UIViewContentModeCenter;
//logoutButton.contentMode = UIViewContentModeCenter;
//logoutButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
//logoutButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
Point 1
AFAIK, UIControlContentVerticalAlignmentCenter & contentHorizontalAlignment is for text alignment and not for image....
Point 2
UIButton *logoutButton = [[UIButton alloc] initWithFrame:logoutButtonFrame]; will create basic button (like < iOS 6) opposed to Custom button. Below is how you should have button programmatically.
UIButton * logoutButton = [UIButton buttonWithType:UIButtonTypeCustom];
[logoutButton setBackgroundImage:[UIImage imageNamed:#"logout.png"] forControlEvents:UIControlEventTouchUpInside];
[logoutButton addTarget:self action:#selector(confirmLogout) forControlEvents:UIControlEventTouchUpInside];
[logoutButton setTitle:#"" forState:UIControlStateNormal];
logoutButton.frame = CGRectMake(logoutButtonX, 0, logoutButtonSize, logoutButtonSize);
[self.view addSubview: logoutButton];
Now for image to adjust,
continueButton.imageView.contentMode = UIViewContentModeScaleAspectFit;
You are done...
And last
Your code is not working because your UIButton is not Custom button.
I have made a floating icon using following code.
- (void)createFloatingButton
{
UIButton *floatingButton = [UIButton buttonWithType:UIButtonTypeCustom];
floatingButton.frame = CGRectMake(kScreenWidth-kFloatingButtonSize-kFloatingButtonSize/2, self.view.frame.size.height-kFloatingButtonSize-kFloatingButtonSize/2, kFloatingButtonSize,kFloatingButtonSize);
[floatingButton setBackgroundColor:kNavColor];
floatingButton.layer.cornerRadius = kFloatingButtonSize/2;
//Configre Font and Text
[floatingButton setTitle:#"+" forState:UIControlStateNormal];
floatingButton.titleLabel.font = [UIFont systemFontOfSize:30];
[floatingButton addTarget:self action:#selector(floatingButtonTapped) forControlEvents:UIControlEventTouchUpInside];
//Mange Alignment
floatingButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
floatingButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
//Add shadow
floatingButton.layer.shadowColor = [[UIColor blackColor] CGColor];
floatingButton.layer.shadowOffset = CGSizeMake(0, 2.0f);
floatingButton.layer.shadowOpacity = 0.6f;
floatingButton.layer.shadowRadius = 3.0f;
floatingButton.layer.masksToBounds = NO;
[self.view addSubview:floatingButton];
}
My output is like that:
I am not able to bring the + in center.
Set UIButton contentEdgeInsets will make your button title adjustments to top, left, bottom, right.
floatingButton.contentEdgeInsets = UIEdgeInsetsMake(top, left, bottom, right);
In your case, it will make title to center
floatingButton.contentEdgeInsets = UIEdgeInsetsMake(0, 2, 3, 0);
Note: as per your given code kFloatingButtonSize is not mentioned, i checked with kFloatingButtonSize = 50
I have a set of UIButtons with background colors. when the user taps one, I want only the button's text to have a shadow all around it (to show that it has been selected). However, when I add the shadow, the shadow appears over the whole button (background and all), and not just the text. Is there an easier workaround to this than just adding a UILabel over a blank button?
UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
...
[button setBackgroundColor:[UIColor blueColor]];
[button.layer setShadowRadius:8.0];
[button.layer setShadowColor:[[UIColor orangeColor] CGColor]];
[button.layer setShadowOpacity:0];
...
Here is the simple way to add shadow to the button title with shadow radius property available in Objective-C:
#import <QuartzCore/QuartzCore.h>
button.titleLabel.layer.shadowOffset = CGSizeMake(2.0, 2.0);
button.titleLabel.layer.shadowColor = [UIColor colorWithWhite:0.1 alpha:0.7].CGColor;
button.titleLabel.layer.shadowRadius = 2.0;
button.titleLabel.layer.shadowOpacity = 1.0;
button.titleLabel.layer.masksToBounds = NO;
Swift ..
Say you override the UIButton class ..
titleLabel!.layer.shadowColor = UIColor.black.cgColor
titleLabel!.layer.shadowOffset = CGSize(width: -0.5, height: 0.5)
titleLabel!.layer.shadowOpacity = 1.0
titleLabel!.layer.shadowRadius = 0
titleLabel!.layer.masksToBounds = false
You need to use setTitleShadowColor: forState: and shadowOffset property of UIButton.
below code will add shadow only to button label whenever user tap on button.
UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
[button setBackgroundColor:[UIColor blueColor]];
button.frame = CGRectMake(50, 70, 200, 100);
[button setTitle:#"Test Button" forState:UIControlStateNormal];
[button.titleLabel setFont:[UIFont systemFontOfSize:45]];
[button setTitleShadowColor:[UIColor redColor] forState:UIControlStateHighlighted];
[button.titleLabel setShadowOffset:CGSizeMake(2.0, 2.0)];
Hope this will help.
Just set the shadow on the titleLabel property of the UIButton rather than what you're doing now.
eg
button.titleLabel.shadowColor = ((selectionState) ?[UIColor orangeColor] : [UIColor clearColor] );
button.titleLabel.shadowOffset = CGSizeMake (1.5,1.5);

This does not work. Use the answer of #Userich
One way to do this is to use attributed strings for the normal and highlighted titles. You can create an NSShadow object, and assign that as the value for the NSShadowAttributeName. This gives you control over the properties of the shadow. To keep the title from dimming, you should set the button type to Custom instead of System.
- (void)viewDidLoad {
[super viewDidLoad];
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor darkGrayColor];
shadow.shadowOffset = CGSizeMake(2, 2);
shadow.shadowBlurRadius = 2;
NSString *titleString = #"Title";
NSAttributedString *normalTitle = [[NSAttributedString alloc] initWithString:titleString];
NSAttributedString *highlightedTitle = [[NSAttributedString alloc] initWithString:titleString attributes:#{NSShadowAttributeName:shadow}];
[self.button setAttributedTitle:normalTitle forState:UIControlStateNormal];
[self.button setAttributedTitle:highlightedTitle forState:UIControlStateHighlighted];
}
I have a UIButton that I have created, and I can successfully add it as a subview and see it on the screen. The problem is, when I try using:
[myButton setTitle:#"My Title" forState:UIControlStateNormal];
The button does not show a title when I run the app. If I NSLog the button's title after using the above method, it has in fact been set to the title that I'm passing in.
Here's my code. This is inside a UIView subclass. I realize that some of this logic might not belong in a UIView subclass but I'm just trying to get this to work as fast as possible:
// Set the view's frame, background color, corner radius
self.frame = CGRectMake(45, 200, 235, 187);
self.backgroundColor = [UIColor whiteColor];
self.layer.borderWidth = 1;
self.layer.borderColor = [UIColor grayColor].CGColor;
self.layer.cornerRadius = 5;
// Create the popup's body text label
self.popupBodyTextLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 100, 150)];
self.popupBodyTextLabel.text = #"Text goes here.";
// Add text view to popup's subviews
[self addSubview:self.popupBodyTextLabel];
// Create ok button
UIButton *myButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 143, 120, 44)];
myButton.backgroundColor = [UIColor whiteColor];
myButton.layer.borderWidth = 1;
myButton.layer.borderColor = [UIColor grayColor].CGColor;
[myButton setTitle:#"OK" forState:UIControlStateNormal];
// Round the button's bottom left corner
UIBezierPath *myButtonMaskPath = [UIBezierPath bezierPathWithRoundedRect:myButton.bounds byRoundingCorners:(UIRectCornerBottomLeft) cornerRadii:CGSizeMake(5.0, 5.0)];
CAShapeLayer *okButtonMaskLayer = [[CAShapeLayer alloc] init];
myButtonMaskLayer.frame = myButton.bounds;
myButtonMaskLayer.path = myButtonMaskPath.CGPath;
myButton.layer.mask = myButtonMaskLayer;
// Add selector to button
[myButton addTarget:self action:#selector(myButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
// Add button to subviews
[self addSubview:myButton];
// Create the background view
self.backgroundView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
self.backgroundView.backgroundColor = [UIColor grayColor];
self.backgroundView.alpha = 0.5f;
// Show our new views
[[[UIApplication sharedApplication] keyWindow] addSubview:self.backgroundView];
[[[UIApplication sharedApplication] keyWindow] addSubview:[MPPopupView shared]];
The code for setting button title is right, so use this code to set title color
[myButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
My code is as follows:
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
CGRect frame = CGRectMake(50, 125, 220, 40);
button.frame = frame;
button.layer.cornerRadius = 20;
button.backgroundColor = [UIColor colorWithRed:0.42 green:0.66 blue:0.31 alpha:1.0];
button.layer.masksToBounds = YES;
[self.view addSubview:button];
button.autoresizesSubviews = NO;
button.clipsToBounds = YES;
UILabel *addLabel = [[UILabel alloc] initWithFrame:CGRectMake(15, 10, 100, 100)];
addLabel.text = #"+";
addLabel.textColor = [UIColor blackColor];
addLabel.textAlignment = NSTextAlignmentCenter;
addLabel.font = [UIFont fontWithName:#"HelveticaNeue-UltraLight" size:80.0f];
[button addSubview:addLabel];
addLabel.autoresizesSubviews = NO;
addLabel.clipsToBounds = YES;
My button is showing up fine in iOS/iPhone simulator, however addLabel label is not showing up at all.
What am I missing?
The frame on your label is too large. The label text is being drawn outside the frame of your button as a result. Ideally, the frame of your label would be at most as tall as the button height.
Well UIButton already has a titleLabel. Have you tried just using that instead?
button.titleLabel.text = "+";
or even using a different button type:
UIButton* button = [UIButton buttonWithType:UIButtonTypeContactAdd];
