如何從UISegmentController中刪除邊界？

Question

我想刪除UISegmentController的邊框。如果可能。否則在自定義邊框顏色中更改它。

Answer 1

變色和分段控制的文本嘗試：

Objective-C的：

NSArray *array = [segmentedControl subviews]; 

[[array objectAtIndex:2] setTintColor:[UIColor redColor]]; 
[[array objectAtIndex:1] setTintColor:[UIColor greenColor]];  
[[array objectAtIndex:0] setTintColor:[UIColor blueColor]]; 

斯威夫特：

let array = segmentedControl.subviews 
array[2].tintColor = UIColor.redColor() 
array[1].tintColor = UIColor.greenColor() 
array[0].tintColor = UIColor.blueColor() 

請注意，subviews與用戶界面相反。

您可以以同樣的方式自定義邊框：

let array = segmentedControl.subviews 
array[0].layer.borderWidth = 5 // change thickness of border 
array[0].layer.cornerRadius = 4 //change corner radius

案例1 - 中segmentedControl

每個元素的自定義邊框顏色

代碼

extension UIView { 
    ///Add border color with corners 
    func addBorderWithColor(color: UIColor, roundingCorners: UIRectCorner) { 
     self.layer.borderWidth = 1 
     self.layer.borderColor = color.CGColor 
     self.addRoundingCorners(roundingCorners) 
    } 

    ///Use corner radius depending on UIRectCorner 
    private func addRoundingCorners(roundingCorners: UIRectCorner) { 
     let path = UIBezierPath(roundedRect:self.bounds, byRoundingCorners:roundingCorners, cornerRadii: CGSizeMake(4, 4)) 

     let maskLayer = CAShapeLayer() 
     maskLayer.path = path.CGPath 
     self.layer.mask = maskLayer 
    } 
} 

let segmentedControl = UISegmentedControl(items: ["Red", "Green", "Blue"]) 

segmentedControl.subviews[0].addBorderWithColor(UIColor.blueColor(), roundingCorners: [.TopRight, .BottomRight]) 
segmentedControl.subviews[1].addBorderWithColor(UIColor.greenColor(), roundingCorners: []) 
segmentedControl.subviews[2].addBorderWithColor(UIColor.redColor(), roundingCorners: [.TopLeft, .BottomLeft]) 

segmentedControl.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blackColor()], forState: UIControlState.Normal)

案例2 - 擺脫邊框

代碼

let segmentedControl = UISegmentedControl(items: ["Red", "Green", "Blue"]) 

//Change Text Attributes (Changing textColor to black) 
//**Be sure to manage all the UIControlState for these attributes if you need to customize this for other states 
segmentedControl.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blackColor()], forState: UIControlState.Normal) 

//Change tintColor to clear, in order to set border invisible 
segmentedControl.tintColor = UIColor.clearColor()

原來的答案

答案是NO
無法刪除的UISegmentedControl

邊框您可以創建使用UIButton取得成就，你在找什麼自定義控件。

在UISegmentedControl狀態，您可以刪除項目之間的分隔在UISegmentedControl，或者您可以更改tintColor（BORDERCOLOR）
