我的登录视图有一个子视图,它有一个UIActivityView和一个UILabel,上面写着“Signing In…”这个子视图有不圆角的角。我怎样才能把它们变圆呢?
有什么办法在我的xib里面做吗?

在obj c中通过编程实现吗
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(20, 50, 200, 200)];
view.layer.backgroundColor = [UIColor whiteColor].CGColor;
view.layer.cornerRadius = 20.0;
view.layer.frame = CGRectInset(v.layer.frame, 20, 20);
[view.layer.shadowOffset = CGSizeMake(1, 0);
view.layer.shadowColor = [[UIColor blackColor] CGColor];
view.layer.shadowRadius = 5;
view.layer.shadowOpacity = .25;][1]
[self.view addSubview:view];
我们也可以从stoaryboard做这个。
layer.cornerRadius Number 5
其他回答
设置圆形视图的转角属性
设置masksToBounds布尔值,图像将不会在角半径边界外绘制
view.layer.cornerRadius = 5;
view.layer.masksToBounds = YES;
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(20, 50, 200, 200)];
view.layer.backgroundColor = [UIColor whiteColor].CGColor;
view.layer.cornerRadius = 20.0;
view.layer.frame = CGRectInset(v.layer.frame, 20, 20);
view.layer.shadowOffset = CGSizeMake(1, 0);
view.layer.shadowColor = [[UIColor blackColor] CGColor];
view.layer.shadowRadius = 5;
view.layer.shadowOpacity = .25;
[self.view addSubview:view];
[view release];
在Swift 4.2和Xcode 10.1中
let myView = UIView()
myView.frame = CGRect(x: 200, y: 200, width: 200, height: 200)
myView.myViewCorners()
//myView.myViewCorners(width: myView.frame.width)//Pass View width
view.addSubview(myView)
extension UIView {
//If you want only round corners
func myViewCorners() {
layer.cornerRadius = 10
layer.borderWidth = 1.0
layer.borderColor = UIColor.red.cgColor
layer.masksToBounds = true
}
//If you want complete round shape, enable above comment line
func myViewCorners(width:CGFloat) {
layer.cornerRadius = width/2
layer.borderWidth = 1.0
layer.borderColor = UIColor.red.cgColor
layer.masksToBounds = true
}
}
在Xcode 6上 你试一试
self.layer.layer.cornerRadius = 5.0f;
or
self.layer.layer.cornerRadius = 5.0f;
self.layer.clipsToBounds = YES;
这是一种不同于Ed Marty的方法:
#import <QuartzCore/QuartzCore.h>
[v.layer setCornerRadius:25.0f];
[v.layer setMasksToBounds:YES];
你需要setMasksToBounds来从IB加载所有的对象…我有一个问题,我的视图得到了圆润,但没有IB的对象:/
这是固定的=D希望它有助于!
