[英]UIBarButtonItem with rounded corners and shadow
I want to have rounded corners and shadow on a UIBarButtonItem
. 我想在
UIBarButtonItem
上有圆角和阴影。
UIButton *useButton = [UIButton buttonWithType:UIButtonTypeCustom];
Then I try to set shadow and rounded corners: 然后我尝试设置阴影和圆角:
useButton.layer.masksToBounds = NO;
useButton.layer.cornerRadius = 4;
useButton.layer.shadowOffset = CGSizeMake(0, 1.5);
useButton.layer.shadowRadius = 0.5;
useButton.layer.shadowOpacity = 1.0;
useButton.layer.shadowColor = [BSTCMColorUtility colorFromHexString:@"#AFAFAF"].CGColor;
Finally I make the UIBarButtonItem
: 最后我创建了
UIBarButtonItem
:
UIBarButtonItem *useItem = [[UIBarButtonItem alloc] initWithCustomView:useButton];
[self.navigationItem setRightBarButtonItems:@[useItem]];
I get no rounded corners, but I do get the shadow. 我没有圆角,但我确实得到了阴影。
If I add: 如果我添加:
useButton.clipsToBounds = YES;
And/or: 和/或:
useButton.layer.masksToBounds = YES;
I get rounded corners, but no shadow. 我得到圆角,但没有阴影。 So I thought that I would try to add a sublayer.
所以我想我会尝试添加一个子图层。
CALayer *useButtonShadowLayer = [CALayer new];
useButtonShadowLayer.frame = useButton.frame;
useButtonShadowLayer.cornerRadius = 4;
useButtonShadowLayer.backgroundColor = [UIColor whiteColor].CGColor;
useButtonShadowLayer.shadowOffset = CGSizeMake(0, 1.5);
useButtonShadowLayer.shadowRadius = 0.5;
useButtonShadowLayer.shadowOpacity = 1.0;
useButtonShadowLayer.shadowColor = [BSTCMColorUtility colorFromHexString:@"#AFAFAF"].CGColor;
useButton.layer.cornerRadius = 4;
useButton.layer.masksToBounds = YES;
UIView *parent = useButton.superview;
[parent.layer insertSublayer:useButtonShadowLayer below:useButton.layer];
It doesn't seem to work, I see no shadow. 它似乎不起作用,我看不到阴影。 I get rounded corners tho.
我得到了圆角。
Isn't possible to have rounded corners AND shadow on a UIBarButtonItem
/ UIButton
? UIBarButtonItem
/ UIButton
上不可能有圆角和阴影?
Try this Updated code : 试试这个更新的代码:

useButton.frame = CGRectMake(100, 430, 100, 40);
useButton.layer.masksToBounds = NO;
useButton.layer.cornerRadius = 10;
useButton.layer.shadowOffset = CGSizeMake(1.5, 1.5);
useButton.layer.shadowRadius = 0.5;
useButton.layer.shadowOpacity = 1.0;
useButton.layer.shadowColor = [UIColor blackColor].CGColor;
useButton.backgroundColor = [UIColor redColor];
UIBarButtonItem *useItem = [[UIBarButtonItem alloc] initWithCustomView:useButton];
[self.navigationItem setRightBarButtonItems:@[useItem]];
UIButton *useButton = [UIButton buttonWithType:UIButtonTypeCustom];
useButton.frame = CGRectMake(0, 0, 60, 30);
useButton.backgroundColor = [UIColor redColor];
useButton.layer.masksToBounds = NO;
useButton.layer.cornerRadius = 4;
useButton.layer.shadowOffset = CGSizeMake(0, 1.5);
useButton.layer.shadowRadius = 5;
useButton.layer.shadowOpacity = 1.0;
// useButton.layer.shadowColor = [UIColor blackColor].CGColor;
useButton.layer.borderColor = [UIColor blackColor].CGColor;
[self.view addSubview:useButton];
UIBarButtonItem *useItem = [[UIBarButtonItem alloc] initWithCustomView:useButton];
[self.navigationItem setRightBarButtonItems:@[useItem]];
btnname.layer.cornerRadius = 8.0;
btnname.layer.shadowOffset = CGSizeMake(2, 2);
btn.layer.cornerRadius = 2.0 ;
buttonName.layer.cornerRadius = 2;
buttonName.layer.borderWidth = 1;
buttonName.layer.borderColor = [UIColor blacColor].CGColor;
