如何为UITextView设置圆角？

Question

如何为UITextView设置圆角？

Answer 1

拳头导入文件

#import <QuartzCore/QuartzCore.h>

然后设置文本视图的属性

yourTextViewName.layer.cornerRadius = kCornerRadius;

其中kCornerRadius是一个常数，你设置为角落的半径

Answer 2

试试这个肯定会起作用

你必须导入

QuartzCore/QuartzCore.h


UITextView* txtView = [[UITextView alloc] initWithFrame:CGRectMake(50, 50, 300, 100)];
txtView.layer.cornerRadius = 5.0;
txtView.clipsToBounds = YES;

Answer 3

我在.h：

中为UITextView定义了一个类别类

@interface UITextView (RoundedCorner)
-(void) roundedCornerDefault;
-(void) roundedCornerWithRadius:(CGFloat) radius
                borderColor:(CGColorRef) color
                borderWidth:(CGFloat) width;
@end

和实现类：

#import <QuartzCore/QuartzCore.h>
#import "UITextView+RoundedCorner.h"

@implementation UITextView (RoundedCorner)

-(void) roundedCornerDefault {
    [self roundedCornerWithRadius:10 
                      borderColor:[[UIColor grayColor] CGColor] 
                      borderWidth:1];
}

-(void) roundedCornerWithRadius:(CGFloat) radius
                    borderColor:(CGColorRef) color
                    borderWidth:(CGFloat) width {
    self.layer.cornerRadius = radius;
self.layer.borderColor = color;
self.layer.borderWidth = width;
self.clipsToBounds = YES;
}
@end

使用它的示例：

#import "UITextView+RoundedCorner.h"
...
[self.myTextView roundedCornerDefault];

按照以下代码和步骤为我工作

1. 创建textView变量

   @IBOutlet weak var currentAddressOutlet: KMPlaceholderTextView!
   

2. 创建此功能

   private func setBorderForTextView() {
   self.currentAddressOutlet.layer.borderColor = UIColor.lightGray.cgColor
   self.currentAddressOutlet.layer.borderWidth = 0.5
   self.currentAddressOutlet.layer.cornerRadius = 5
   }
   

3. 在viewDidLoad中调用上述函数

   override func viewDidLoad() {
   super.viewDidLoad()
   setupTable()
   setBorderForTextView()
   } 
   

4. 结果在这里
