I have next code;
self.tableView.layer.cornerRadius = 4;
self.tableView.layer.masksToBounds = NO;
self.tableView.layer.shadowColor = [[UIColor blackColor] CGColor];
self.tableView.layer.shadowOffset = CGSizeMake(0.0f,0.5f);
self.tableView.layer.shadowOpacity = .5f;
self.tableView.layer.shadowRadius = 0.5f;
in description on property masksToBounds is writing that default is NO. But if I don't right in code it explicitly, shadow not appear. Why default value (NO) not working?
Because the tableView's ScrollView also has the property set.

I have tried to assign shadow to UIButton with the help of following code :
self.addCardButton.layer.masksToBounds = NO;
self.addCardButton.layer.shadowOffset =CGSizeZero;
self.addCardButton.layer.shadowRadius = 5;
self.addCardButton.layer.shadowOpacity = 1.0;
self.addCardButton.layer.cornerRadius = 5.0;
self.addCardButton.layer.borderColor = [[UIColor lightGrayColor]CGColor];
self.addCardButton.layer.borderWidth = 0.5;
self.addCardButton.layer.shadowColor = [[UIColor lightGrayColor] CGColor];
In viewdidload().
Still getting zero results.... please help me in knowing possible reasons for this glitch.
I am trying to animate a button with some glow effect.
So far this is what I got:
self.glowLayer = [[CALayer alloc] init];
self.glowLayer.contents = (__bridge id _Nullable)(self.currentBackgroundImage.CGImage);
self.glowLayer.opacity = 0; // set to 1 with animation.
self.glowLayer.shadowColor = [UIColor vtoPinkColor].CGColor;
self.glowLayer.shadowOffset = CGSizeZero;
self.glowLayer.shadowRadius = 5;
self.glowLayer.shadowOpacity = 1;
self.glowLayer.rasterizationScale = [UIScreen mainScreen].scale;
self.glowLayer.shouldRasterize = YES;
[self.layer addSublayer:self.glowLayer];
However, I find the glow effect not strong enough.
Of course I can change the shadow radius to make it wider but it only makes the shadow "dilute" instead of getting stronger.
How should I proceed ?
changing the value of
self.glowLayer.shadowOpacity 1 will work for you.
and also try Translucent = No
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];
Here is my code for set the border, shadow and corner
// set border
[self.avatarImageView.layer setBorderColor: [[UIColor whiteColor] CGColor]];
[self.avatarImageView.layer setBorderWidth: 2.0];
// set shadow
[self.avatarImageView.layer setShadowOffset:CGSizeZero];
[self.avatarImageView.layer setShadowOpacity:1.0];
self.avatarImageView.clipsToBounds = NO;
// set corner
self.avatarImageView.layer.cornerRadius = 10.0;
self.avatarImageView.layer.masksToBounds = YES;
If I only use the code for set border and set corner, it work well like this
But if I add the code set corner, I will got the result like this (the border and corner radius work, but the shadow is gone)
However the code for set corner work perfect if it stay alone.
Please guide me what to do. Any help would be appreciate
Update
Follow #ozgur answer. Add 2 lines to my code, it will give a very beautiful view but the shadow is a little bit smaller
self.avatarImageView.layer.shouldRasterize = YES;
self.avatarImageView.layer.shadowPath = [UIBezierPath bezierPathWithRoundedRect:self.avatarImageView.bounds cornerRadius:10].CGPath;
Rounded corners requires masksToBounds to be set to YES. Because of that nothing past the boundaries (like a shadow) can be shown, because it will be masked/clipped off. If you disable masksToBounds so that it will show then the rounded corners wont work because they are unable to mask/clip your image into the rounded shape because you disabled masksToBounds.
Therefor, you can't do both at the same time on one view—so you need TWO views.
You need to make a UIView the same dimensions as your UIImageView and make the UIImageView a subview of your UIView.
Then on your UIImageView set masksToBounds to YES, and on its' superview (the UIView with the same dimensions) set masksToBounds to NO and add the properties accordingly.
Change your code to this: (typed it all w/o using xCode so it's possible I have typos)
UIView *avatarImageViewHolder = [[UIView alloc] initWithFrame:self.avatarImageView.frame];
avatarImageViewHolder.backgroundColor = [UIColor clearColor];
[avatarImageView.superview addSubview:avatarImageViewHolder];
avatarImageViewHolder.center = avatarImageView.center;
[avatarImageViewHolder addSubview:avatarImageView];
avatarImageView.center = CGPointMake(avatarImageViewHolder.frame.size.width/2.0f, avatarImageViewHolder.frame.size.height/2.0f);
self.avatarImageView.layer.masksToBounds = YES;
avatarImageViewHolder.layer.masksToBounds = NO;
// set avatar image corner
self.avatarImageView.layer.cornerRadius = 10.0;
// set avatar image border
[self.avatarImageView.layer setBorderColor: [[UIColor whiteColor] CGColor]];
[self.avatarImageView.layer setBorderWidth: 2.0];
// set holder shadow
[avatarImageViewHolder.layer setShadowOffset:CGSizeZero];
[avatarImageViewHolder.layer setShadowOpacity:1.0];
avatarImageViewHolder.clipsToBounds = NO;
You need to add a container view and move your imageview inside that container view, Use this code after doing so:
CALayer *imageViewLayer= self.imageView.layer;
imageViewLayer.cornerRadius= 20.0f;
imageViewLayer.masksToBounds= YES;
CALayer *containerLayer = self.containerView.layer;
containerLayer.borderColor= [UIColor whiteColor].CGColor;
containerLayer.borderWidth= 3.0f;
containerLayer.cornerRadius= 20.0f;
containerLayer.shadowOffset = CGSizeMake(0, 0);
containerLayer.shadowColor = [UIColor blackColor].CGColor;
containerLayer.shadowRadius = 10.0f;
containerLayer.shadowOpacity = 0.80f;
containerLayer.masksToBounds= NO;
containerLayer.shadowPath = [[UIBezierPath bezierPathWithRect:containerLayer.bounds] CGPath];
Feel free to tweak the settings as per your need. Enjoy!
You should update layer.shadowPath if you don't want the shadow to get clipped:
self.avatarImageView.layer.shouldRasterize = YES;
self.avatarImageView.layer.shadowPath = [UIBezierPath bezierPathWithRoundedRect:self.avatarImageView.bounds cornerRadius:10].CGPath;
For this trick to work, clipsToBounds and his brother masksToBounds should be set to NO.
Thus, if you have an image whose size is greater than the avatarView's own bounds, you should define avatarImageView as plain UIView, create another imageView to display the image set its masksToBounds to YES and add it as a subview to avatarImageView so that you'll have a good cornered and shadowed view capable of displaying the clipped image.
You should set self.avatarImageView.clipsToBounds = YES; in set corner
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)

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;
}
