I'd to create a UITextField like find iPhone.
I used the follow code for the UITextField:
UIBezierPath *maskPathBotton = [UIBezierPath bezierPathWithRoundedRect:txtSenha.bounds
byRoundingCorners:UIRectCornerBottomLeft|UIRectCornerBottomRight
cornerRadii:CGSizeMake(8.0, 8.0)];
txtSenha.borderStyle=UITextBorderStyleNone;
CAShapeLayer *maskLayerBotton = [CAShapeLayer layer];
maskLayerBotton.frame = txtSenha.bounds;
maskLayerBotton.path = maskPathBotton.CGPath;
maskLayerBotton.fillColor=[UIColor whiteColor].CGColor;
maskLayerBotton.strokeColor=[UIColor lightGrayColor].CGColor;
maskLayerBotton.lineWidth=1.5;
[txtSenha.layer addSublayer:maskLayerBotton];
But the result wasn't so good.
In the corners the strokes are a little more different than the other lines. How can I create the same UITextField. Sorry for my English and for no image, I don't have enough reputation to upload an image.
EDIT:
UITextField from Find Iphone
And this, is that I could.
if you want rounded corner try this
textField.layer.cornerRadius = 10;
Be sure to include #import <QuartzCore/QuartzCore.h> to access this.
or
remove this line from your code
textField.borderStyle = UITextBorderStyleRoundedRect;
instead of
[textField setBackgroundColor:[UIColor clearColor]];
[textField.layer setBorderColor:[UIColor grayColor].CGColor];
[textField.layer setBorderWidth:1.0];

Here is my code to add a shadow on my uibutton which is created using a .XIB file
UIBezierPath *shadowPathEndbtn = [UIBezierPath bezierPathWithRect:CGRectMake(0, self->_navigationView.frame.size.height - 70,[UIScreen mainScreen].bounds.size.width , 2)];
self->_EndButton.layer.masksToBounds = NO;
self->_EndButton.layer.shadowColor = [UIColor blackColor].CGColor;
self->_EndButton.layer.shadowOffset = CGSizeMake(0.0f, 5.0f);
self->_EndButton.layer.shadowOpacity = 0.7f;
self->_EndButton.layer.shouldRasterize = YES;
self->_EndButton.layer.shadowPath = shadowPathForEndbtn.CGPath;
I am able to set the shadow using this code but this code makes my button text look blury. I am unable to figure out the exact reason behind this. Any help is Appreciated!
self->_EndButton.layer.masksToBounds = false
self->_EndButton.layer.shadowColor = [UIColor blackColor].CGColor
self->_EndButton.layer.contentsScale = [[UIScreen mainScreen]scale];
self->_EndButton.layer.shadowOpacity = 0.7f;
self->_EndButton.layer.shadowRadius = 10.0;
self->_EndButton.layer.shadowOffset = CGSizeMake(0,0)
This will give shadow and also the test is not blurry
Set button background color
self.EndButton.BackgroundColor=[UIColor WhiteColor];
I want to customize a UITextField in iOS 6 which will look like a transparent text field with only a bottom border.I have found one image in stackoverflow earlier,but as I don't have 10 reputation I can't post a image,but I am posting the link below.
Text field with bottom border only in ios6
There are multiple ways to accomplish this:
Create a seperatorView and add it subview to UITextfield with y axis as the height of textfield.
UITextfield *namefield = [[UITextfield alloc] initwithframe:CGRectMake(20,40,70,40) ];
UIView *seperator=[UIView new];
seperator.backgroundColor = [UIColor grayColor];
seperator.frame =CGRectMake(namefield.frame.origin.x, namefield frame.origin.y+namefield.frame.size.height-1, namefield.frame.size.width,1);
[namefield addSubView:seperator];
By using the CoreAnimation Class
CALayer *bottomBorder = [CALayer layer];
CGFloat borderWidth = 1;
bottomBorder.borderColor = [UIColor grayColor].CGColor;
bottomBorder.frame = CGRectMake(0, textField.frame.size.height - borderWidth, textField.frame.size.width, textField.frame.size.height);
bottomBorder.borderWidth = borderWidth;
[textField.layer addSublayer:border];
textField.layer.masksToBounds = YES;
By creating a custom class for UITextField and overriding drawRect method.
Using a image and adding as a backgroundColor to UITextfield.
I'm creating a UILabel to which I set the background color and corner radius with the following code:
self.scoreLabel.backgroundColor = [UIColor DISRed];// custom red`
self.scoreLabel.layer.masksToBounds = YES;
self.scoreLabel.layer.cornerRadius = self.scoreLabel.frame.size.width/2;
self.scoreLabel.layer.borderWidth = 8.0;
self.scoreLabel.layer.borderColor = [[UIColor DISNavy] CGColor];
However the background's color seems to be leaking to the edge of the border (see image). Any ideas why? Any idea on how to fix it?
I was also facing the same problem. It was a silly mistake. I always forget to tick clipToBounds in case of cornerRadius.
So, just ticking the Clip to Bounds for UILabel in Storyboard fixed my problem.
And yes, we need to keep the below code too:
label.layer.masksToBounds = true
I ran into the same problem with the UIButton's background color leaking around the edge of its border.
Instead of setting the UIButton background color on the UIButton, set it on the UIButton's layer.
Replace:
self.scoreLabel.backgroundColor = [UIColor DISRed];// custom red`
With this:
self.scoreLabel.layer.backgroundColor = [[UIColor DISRed] CGColor];// custom red`
I created my own UILabel and background colour does not seem to be leaking.
Write this in .h file of your project.
UILabel *label;
Write this in .m file of your project.
label=[[UILabel alloc]initWithFrame:CGRectMake(100, 300, 100, 100)];//Set frame of label in your viewcontroller.
[label setBackgroundColor:[UIColor redColor]];//Set background color of label.
[label setText:#"Label"];//Set text in label.
[label setTextColor:[UIColor blackColor]];//Set text color in label.
[label setTextAlignment:NSTextAlignmentCenter];//Set text alignment in label.
[label.layer setCornerRadius:50.0];//Set corner radius of label to change the shape.
[label.layer setBorderWidth:8.0f];//Set border width of label.
[label setClipsToBounds:YES];//Set its to YES for Corner radius to work.
[label.layer setBorderColor:[UIColor greenColor].CGColor];//Set Border color.
[self.view addSubview:label];//Add it to the view of your choice.
It is probably anti aliasing issue. you can better fix it by adding a bezier path around the corners.
CAShapeLayer *subLayer = [[CAShapeLayer alloc] init];
[subLayer setFillColor:[UIColor clearColor].CGColor];
[subLayer setStrokeColor:[UIColor whiteColor].CGColor];
[subLayer setLineWidth:1.0];
[subLayer setPath:[UIBezierPath bezierPathWithRoundedRect:imageView.bounds cornerRadius:imageView.layer.cornerRadius].CGPath];
[imageView.layer addSublayer:subLayer];
For those who are still facing the issue of border color leaking out:
Go through the below code, please note you will need to set frames & border width as per your requirement, I'm setting the position as view's center
let badgeSize: CGFloat = 10
let redBadge = UIView(frame: CGRect(x: view.center.x, y:view.center.y, width: badgeSize, height: badgeSize))
redBadge.layer.borderColor = UIColor.white.cgColor
redBadge.layer.borderWidth = 2
redBadge.backgroundColor = .red
redBadge.layer.cornerRadius = badgeSize * 0.5
redBadge.clipsToBounds = true
redBadge.layer.masksToBounds = true
redBadge.maskLayerOnView(radius: badgeSize * 0.5)
view.addSubview(redBadge)
Secondly, we need to write an extension on UIView
extension UIView{
func maskLayerOnView(radius: CGFloat){
let maskLayer = CAShapeLayer()
maskLayer.path = UIBezierPath(roundedRect: self.bounds,
byRoundingCorners: [.allCorners],
cornerRadii: CGSize(width: radius,
height: radius)).cgPath
self.layer.mask = maskLayer
}
}
This code snippet removes the border color separating out, one can replicate this behaviour on any kind of views.
For detailed explanation please see this article.
Well, a lot of answers...
I found the problem persists, as long as the UIViews background color is used and not the background color of the UIViews 'layer'. In addition, of course, masking needs to be enabled.
For a UICollectionViewCell subclass the code is:
- (void)prepare
{
self.contentView.layer.backgroundColor = UIColor.redColor.CGColor;
self.contentView.layer.cornerRadius = 25.0;
self.contentView.layer.borderColor = UIColor.blackColor.CGColor;
self.contentView.layer.borderWidth = 1.0;
//Enable to optimize image views: self.contentView.layer.shouldRasterize = YES;
//Enable to optimize image views: self.contentView.layer.rasterizationScale = UIScreen.mainScreen.scale;
self.contentView.layer.masksToBounds = YES;
self.contentView.clipsToBounds = YES;
}
To make the setting of the background color more comfortable and less error prone, some could add this:
/*
setBackgroundColor:
*/
- (void)setBackgroundColor:(UIColor *)p_BackgroundColor
{
super.backgroundColor = nil;
self.contentView.layer.backgroundColor = p_BackgroundColor.CGColor;
self.contentView.layer.masksToBounds = YES;
self.contentView.clipsToBounds = YES;
}
I am trying to provide a shadow effect to my Imageview just like in this image.
but the problem which I am facing it is that the shadow is actually visible from the bottom of the Imageview.
Here is the code which I have done to add the shadow. The color and all is still not matching with this one.
CAGradientLayer *shadow = [CAGradientLayer layer];
shadow.frame = CGRectMake(-100, 70, perspectiveView.frame.size.width,
perspectiveView.frame.size.height - 20);
shadow.startPoint = CGPointMake(1.0, 0.5);
shadow.endPoint = CGPointMake(0, 0.5);
shadow.colors = [NSArray arrayWithObjects:(id)[[UIColor colorWithWhite:0.0
alpha:0.4f] CGColor], (id)[[UIColor clearColor] CGColor], nil];
shadow.opacity = 1.0f;
[perspectiveView.layer addSublayer:shadow];
Please provide inputs. Also if the approach is wrong, feel free to guide me to any other approach.
Thanks in advance.
Also can anyone suggest how to provide a 3D border just like in the image which provides a slight width to the image view?
Perhaps, adding a shadow to the layer seems to work. You may want to try something like this:
// perspectiveView.transform = CGAffineTransformMakeRotation(-50.0f);
perspectiveView.layer.shadowOffset = CGSizeMake(10, 10);
perspectiveView.layer.shadowRadius = 5.0;
perspectiveView.layer.shadowOpacity = 0.6;
perspectiveView.layer.masksToBounds = NO;
You will need to playaround with these values to match your requirements. Hope this helps.
Here is my output:
Try this,
- (void)setShadow {
[perspectiveView.layer setShadowOffset:CGSizeMake(-5.0, 5.0)];
[perspectiveView.layer setShadowRadius:5.0];
[perspectiveView.layer setShadowOpacity:1.0];
}
you can use CALayer class , the layer can manage your visual aspects like background color, border, shadow and with it you can also manage the geometry of it content like size , transform etc .
visual effect(shadowing)
self.yourView.layer.shadowOffset = CGSizeMake(0, 3);
self.yourView.layer.shadowRadius = 5.0;
self.yourView.layer.shadowColor = [UIColor blackColor].CGColor;
self.yourView.layer.shadowOpacity = 1;
and you also used it for like self.yourView.layer.frame(Geometry)
more info https://developer.apple.com/library/ios/documentation/graphicsimaging/reference/CALayer_class/index.html
Below code work i have checked properly.
but Shikhar varshney can u check setShadow method call and perspectiveView is not nil.
- (void)setShadow {
perspectiveView.layer.shadowColor = [UIColor colorWithWhite:0.0
alpha:0.4f] CGColor;
perspectiveView.layer.shadowOffset = CGSizeMake(0, 1);
perspectiveView.layer.shadowOpacity = 1;
perspectiveView.layer.shadowRadius = 1.0;
perspectiveView.clipsToBounds = NO;
}
I need to draw a rectangle on top of a UIButton. Assume that there's a UIButton called hideMe, and this button has 100x50 size. I want to place a 100x10 rectangle on top of this button every time a user receives a message. If the user receives five messages, then the button will be completely covered by the rectangles. How do I do this?
CALayer *topBorder = [CALayer layer];
topBorder.borderColor = [UIColor redColor].CGColor;
topBorder.backgroundColor = [UIColor blackColor].CGColor;
topBorder.borderWidth = 2;
topBorder.frame = CGRectMake(0, 15, <tempButton>.frame.size.width, <tempButton>.frame.size.height-30);
[<tempButton>.layer addSublayer:topBorder];
The above code helps you to draw the rectangle.You can increase the layer frames to cover full.
try this
#import <QuartzCore/QuartzCore.h>
here we are drawing our own border rect and sub viewing it to our button
-(UIView*)borderRectWithYvalue:(CGFloat)yValue
{
UIView * rect = [[UIView alloc] initWithFrame:CGRectMake(0,yValue, 100, 10)];
rect.backgroundColor = [UIColor lightGrayColor];
rect.layer.borderColor = (__bridge CGColorRef)([UIColor redColor]);
rect.layer.borderWidth = 2.0f;
return rect;
}
and call this method when and where you want to add border to your button with your custom y value
for ex
[yourButton addSubview:[self borderRectWithYvalue:10.0]];
