I am trying to add border line between 2 UIView, as i researched, the following code can add 4 borders.
CGFloat borderWidth = 5.0f;
self.imgview.frame = CGRectInset(self.imgview. frame, -borderWidth, -borderWidth);
self.imgview. layer.borderColor = [UIColor blueColor].CGColor;
self.imgview. layer.borderWidth = borderWidth;
However, i just need to add one border, any advice? Thanks in advance.
You can add one One more UIView (BorderView) between two UIView (View1 and View2). Give the border view appropriate width and background color.
If you want to set these borders programmatically, you can use the following snippet of code
+(void)SetImageViewBottomBorder :(UIImageView *)imageView{
CALayer *border = [CALayer layer];
CGFloat borderWidth = 1;
border.borderColor = [[self colorWithHexString:#"9B9B9B"] CGColor];
border.frame = CGRectMake(0, imageView.frame.size.height - borderWidth, imageView.frame.size.width, imageView.frame.size.height);
border.borderWidth = borderWidth;
[imageView.layer addSublayer:border];
imageView.userInteractionEnabled = YES;
imageView.layer.masksToBounds = YES;
}
you can replace the UIImageView with UIView and it will be working like a charm.

I am creating UITextField programatically and i am trying to create a textField that has only bottom border as given in the figure. Please help this problem in objective-c programatically ?
First:
Add and import QuartzCore framework.
#import <QuartzCore/QuartzCore.h>
Second:
CALayer *border = [CALayer layer];
CGFloat borderWidth = 2;
border.borderColor = [UIColor grayColor].CGColor;
border.frame = CGRectMake(0, textField.frame.size.height - borderWidth, textField.frame.size.width, textField.frame.size.height);
border.borderWidth = borderWidth;
[textField.layer addSublayer:border];
textField.layer.masksToBounds = YES;
EDIT:
If you have more TextFields, make one common method which takes UITextField and applies border to it like below:
-(void)SetTextFieldBorder :(UITextField *)textField{
CALayer *border = [CALayer layer];
CGFloat borderWidth = 2;
border.borderColor = [UIColor grayColor].CGColor;
border.frame = CGRectMake(0, textField.frame.size.height - borderWidth, textField.frame.size.width, textField.frame.size.height);
border.borderWidth = borderWidth;
[textField.layer addSublayer:border];
textField.layer.masksToBounds = YES;
}
Pass your TextField as follows to set Bottom Border:
[self SetTextFieldBorder:YourTextField];
Or you can add a thin line subview to the textfield that will mimic the border:
UIView *lineView = [[UIView alloc] init];
lineView.translatesAutoresizingMaskIntoConstraints = false;
lineView.backgroundColor = [UIColor grayColor];
[textField addSubview:lineView];
[lineView.heightAnchor constraintEqualToConstant:1];
[lineView.leftAnchor constraintEqualToAnchor:textField.leftAnchor constant:5.0];
[lineView.rightAnchor constraintEqualToAnchor:textField.rightAnchor constant:-5.0];
[lineView.bottomAnchor constraintEqualToAnchor:textField.bottomAnchor constant:0.0];
Swift version:
let lineView = UIView()
lineView.translatesAutoresizingMaskIntoConstraints = false
lineView.backgroundColor = UIColor.grayColor()
textField.addSubview(lineView)
lineView.heightAnchor.constraintEqualToConstant(1)
lineView.leftAnchor.constraintEqualToAnchor(textField.leftAnchor)
lineView.rightAnchor.constraintEqualToAnchor(textField.rightAnchor)
lineView.bottomAnchor.constraintEqualToAnchor(textField.bottomAnchor)
I want to make visible just bottom border of TextView. How can I do it?
Can I make visible just bottom side of the textView or there are another method?
You can add layer for your aim, but I'm not sure that is right way.
+ (void)addBottomBorderToView: (UIView * ) view WithColor:(UIColor *)color andWidth:(CGFloat) borderWidth
{
CALayer * bottomBorder = [CALayer layer];
bottomBorder.borderColor = color.CGColor;
bottomBorder.borderWidth = borderWidth;
bottomBorder.frame = CGRectMake(0, view.frame.size.height - borderWidth, view.frame.size.width, borderWidth);
[view.layer addSublayer:bottomBorder];
}
How can I add a right and left border in a UIButton with rounded corners?
This is my button and I want rounded corners in the border too:
And the source code of my button:
- (void)initialise;
{
//add border
[self addBottomBorderWithColor:[UIColor grayColor] andWidth:2];
[self addRightBorderWithColor:[UIColor grayColor] andWidth:2];
//round
self.layer.cornerRadius = 8.0f;
}
- (void)addTopBorderWithColor:(UIColor *)color andWidth:(CGFloat) borderWidth
{
CALayer *border = [CALayer layer];
border.backgroundColor = color.CGColor;
border.frame = CGRectMake(0, 0, self.frame.size.width, borderWidth);
[self.layer addSublayer:border];
}
- (void)addRightBorderWithColor:(UIColor *)color andWidth:(CGFloat) borderWidth
{
CALayer *border = [CALayer layer];
border.backgroundColor = color.CGColor;
border.frame = CGRectMake(self.frame.size.width, 0, borderWidth, self.frame.size.height);
[self.layer addSublayer:border];
}
you can add a single CALayer slightly larger than your button and offsetting it with a negative margin so that top and left border are hidden. Mind that i cannot test it right now, and it may need further adjustments but it should give you the general idea:
-(void)initialise;
{
//add border
[self addBorderWithColor:[UIColor grayColor] andWidth:2];
//round
self.layer.cornerRadius = 8.0f;
}
- (void)addBorderWithColor:(UIColor *)color andWidth:(CGFloat) borderWidth
{
CALayer *border = [CALayer layer];
border.borderColor = color.CGColor;
border.frame = CGRectMake(-borderWidth, -borderWidth, self.frame.size.width+borderWidth, self.frame.size.height+borderWidth);
border.borderWidth = borderWidth;
border.cornerRadius = 8.f;
[self.layer addSublayer:border];
self.layer.masksToBounds = YES;
}
I use this code in my customized UIView initialization:
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
...
UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:CGRectMake(frame.origin.x, frame.size.height, frame.size.width, 15)];
self.layer.masksToBounds = NO;
self.layer.shadowColor = [UIColor blackColor].CGColor;
self.layer.shadowOffset = CGSizeMake(0.0f, 4.0f);
self.layer.shadowOpacity = 0.5f;
self.layer.shadowPath = shadowPath.CGPath;
}
return self;
}
trying to make a drop shadow like this:
1)
But I got this effect:
2)
You can see this is an upside down version of what I want to achieve. How to make the shadow effect of the first image?
The issue is just with your shadowPath.
Using CGRectMake(frame.origin.x, frame.size.height, frame.size.width, 15) to create your UIBezierPath will set an incorrect origin.
First, origin.x should be 0.0f or the shadow will shift far away if your UIView's origin.x != 0.0f. Second, you need to line up the bottom of the shadowPath with the bottom of your UIView.
This is a screenshot of UIViews using your shadow code illustrating these issues. (In the lower UIView you cannot see the shadow because it is far off the right of the screen).
You will see what you intended if you change the rect to:
const CGFloat shadowRectHeight = 15.0f;
CGRect shadowRect = CGRectMake(0.0f, self.bounds.size.height - shadowRectHeight, self.bounds.size.width, shadowRectHeight)];
Do like this and set the UIView alpha
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = rect;
gradient.colors = [NSArray arrayWithObjects:(id)[UIColor blackColor].CGColor,
(id)[UIColor grayColor].CGColor,
(id)[UIColor blackColor].CGColor,nil];
[self.layer insertSublayer:gradient atIndex:0];
you can add or remove UIColor you want to display.
Is it possible to add a border just on top of a UIView, if so, how please?
I just Testing Bellow few line of Code and it works very nice, just test it in to your Project. hope you'll get your solution easily.
Why to create new View and adding it into your existing view..? For this task simply create one CALayer and add it into your existing UIView's Layer do as following:-
#import <QuartzCore/QuartzCore.h>
- (void)viewDidLoad
{
CALayer *TopBorder = [CALayer layer];
TopBorder.frame = CGRectMake(0.0f, 0.0f, myview.frame.size.width, 3.0f);
TopBorder.backgroundColor = [UIColor redColor].CGColor;
[myview.layer addSublayer:TopBorder];
[super viewDidLoad];
}
and It's Output is:-
i've find solution for me, here's the tricks :
CGSize mainViewSize = self.view.bounds.size;
CGFloat borderWidth = 1;
UIColor *borderColor = [UIColor colorWithRed:37.0/255 green:38.0/255 blue:39.0/255 alpha:1.0];
UIView *topView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, mainViewSize.width, borderWidth)];
topView.opaque = YES;
topView.backgroundColor = borderColor;
topView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleBottomMargin;
[self.view addSubview:topView];
GilbertOOI's answer in Swift 2:
let topBorder: CALayer = CALayer()
topBorder.frame = CGRectMake(0.0, 0.0, myView.frame.size.width, 3.0)
topBorder.backgroundColor = UIColor.redColor().CGColor
myView.layer.addSublayer(topBorder)
Here's a UIView category that lets you add a layer-back or view-backed border on any side of the UIView: UIView+Borders
GilbertOOI's answer in Swift 4:
let topBorder: CALayer = CALayer()
topBorder.frame = CGRect(x: 0, y: 0, width: myView.frame.size.width, height: 1)
topBorder.backgroundColor = UIColor.purple.cgColor
myView.layer.addSublayer(topBorder)
I created this simple UIView subclass so that it works in Interface Builder and works with constraints:
https://github.com/natrosoft/NAUIViewWithBorders
Here's my blog post about it:
http://natrosoft.com/?p=55
-- Basically just drop in a UIView in Interface Builder and change its class type to NAUIViewWithBorders.
-- Then in your VC's viewDidLoad do something like:
/* For a top border only ———————————————- */
self.myBorderView.borderColorTop = [UIColor redColor];
self.myBorderView..borderWidthsAll = 1.0f;
/* For borders with different colors and widths ————————— */
self.myBorderView.borderWidths = UIEdgeInsetsMake(2.0, 4.0, 6.0, 8.0);
self.myBorderView.borderColorTop = [UIColor blueColor];
self.myBorderView.borderColorRight = [UIColor redColor];
self.myBorderView.borderColorBottom = [UIColor greenColor];
self.myBorderView.borderColorLeft = [UIColor darkGrayColor];
Here's a direct link to the .m file so you can see the implementation: NAUIViewWithBorders.m
There is a demo project as well.
remus' answer in Obj-C:
CALayer *topBorder = [CALayer new];
topBorder.frame = CGRectMake(0.0, 0.0, self.frame.size.width, 3.0);
topBorder.backgroundColor = [UIColor redColor].CGColor;
[myView.layer addSublayer:topBorder];
Swift5:
We will write a separate method to add borders to this view. To add borders to this view we will create two layers with the desired thickness. We will set the frame of these two layers to the top and bottom of the view. We will set the desired background color of the borders on these layers and add these layers as subLayers to the view.
func addTopBorders() {
let thickness: CGFloat = 1.0
let topBorder = CALayer()
topBorder.frame = CGRect(x: 0.0, y: 0.0, width:
self.down_view_outlet.frame.size.width, height: thickness)
topBorder.backgroundColor = UIColor.white.cgColor
down_view_outlet.layer.addSublayer(topBorder)
}
