swift uitableview（swift uicollectionview）

IOS 开发之swift中UIView的扩展使用的实例

扩展类代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 import UIKit extension UIView { // MARK : 坐标尺寸 var origin:CGPoint { get { return self.frame.origin } set(newValue) { var rect = self.frame rect.origin = newValue self.frame = rect } } var size:CGSize { get { return self.frame.size } set(newValue) { var rect = self.frame rect.size = newValue self.frame = rect } } var left:CGFloat { get { return self.frame.origin.x } set(newValue) { var rect = self.frame rect.origin.x = newValue self.frame = rect } } var top:CGFloat { get { return self.frame.origin.y } set(newValue) { var rect = self.frame rect.origin.y = newValue self.frame = rect } } var right:CGFloat { get { return (self.frame.origin.x + self.frame.size.width) } set(newValue) { var rect = self.frame rect.origin.x = (newValue - self.frame.size.width) self.frame = rect } } var bottom:CGFloat { get { return (self.frame.origin.y + self.frame.size.height) } set(newValue) { var rect = self.frame rect.origin.y = (newValue - self.frame.size.height) self.frame = rect } } // MARK: - 位移 // 移动到指定中心点位置 func moveToPoint(point:CGPoint) -> Void { var center = self.center center.x = point.x center.y = point.y self.center = center } // 缩放到指定大小 func scaleToSize(scale:CGFloat) -> Void { var rect = self.frame rect.size.width *= scale rect.size.height *= scale self.frame = rect } // MARK: - 毛玻璃效果 // 毛玻璃 func effectViewWithAlpha(alpha:CGFloat) -> Void { let effect = UIBlurEffect.init(style: UIBlurEffectStyle.Light) let effectView = UIVisualEffectView.init(effect: effect) effectView.frame = self.bounds effectView.alpha = alpha self.addSubview(effectView) } // MARK: - 边框属性 // 圆角边框设置 func layer(radius radius:CGFloat, borderWidth:CGFloat, borderColor:UIColor) -> Void { if (0.0 < radius) { self.layer.cornerRadius = radius self.layer.masksToBounds = true self.clipsToBounds = true } if (0.0 < borderWidth) { self.layer.borderColor = borderColor.CGColor self.layer.borderWidth = borderWidth } } // MARK: - 翻转 // 旋转旋转180度 M_PI func viewTransformWithRotation(rotation:CGFloat) -> Void { self.transform = CGAffineTransformMakeRotation(rotation); } // 缩放 func viewScaleWithSize(size:CGFloat) -> Void { self.transform = CGAffineTransformScale(self.transform, size, size); } // 水平，或垂直翻转 func viewFlip(isHorizontal:Bool) -> Void { if (isHorizontal) { // 水平 self.transform = CGAffineTransformScale(self.transform, -1.0, 1.0); } else { // 垂直 self.transform = CGAffineTransformScale(self.transform, 1.0, -1.0); } } }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 let imageView = UIImageView.init(frame: CGRectMake(10.0, 10.0, 60.0, 60.0)) self.view.addSubview(imageView) imageView.image = UIImage(named: "header") imageView.backgroundColor = UIColor.colorRandom() imageView.left = 100.0 imageView.top = 100.0 imageView.size = CGSizeMake(100.0, 100.0) imageView.moveToPoint(CGPointMake(100.0, 100.0)) imageView.scaleToSize(2.0) imageView.effectViewWithAlpha(0.6) imageView.layer(radius: 3.0, borderWidth: 1.0, borderColor: UIColor.redColor()) imageView.viewFlip(false) imageView.viewTransformWithRotation(5.0)
