iOS中UIKit——UIButton设置边框

UIButton*testButton = [UIButtonbuttonWithType:UIButtonTypeSystem];

[testButtonsetFrame:CGRectMake(self.view.frame.size.width/2,self.view.frame.size.height/2,100,100)];

[testButtonsetTitle:@"获取屏幕尺寸"forState:UIControlStateNormal];

[testButton.layersetMasksToBounds:YES];//设置按钮的圆角半径不会被遮挡

[testButton.layersetCornerRadius:10];

[testButton.layersetBorderWidth:2];//设置边界的宽度

//设置按钮的边界颜色

CGColorSpaceRefcolorSpaceRef =CGColorSpaceCreateDeviceRGB();

CGColorRefcolor =CGColorCreate(colorSpaceRef, (CGFloat[]){1,0,0,1});

[testButton.layersetBorderColor:color];

[testButtonaddTarget:selfaction:@selector(touch)forControlEvents:UIControlEventTouchUpInside];

[self.viewaddSubview:testButton];
