[iOS]UIView+BorderLine

本文主要是介绍[iOS]UIView+BorderLine，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

经常遇到给UIView添加边框的需求,最近看见以前别人项目中写的这种方式比较好用,这里也备个份.

- (void)viewDidLoad {[super viewDidLoad];[_view1 addBorderLineWithBorderWidth:1 borderColor:[UIColor redColor] cornerRadius:10];[_view2 addBorderLineWithBorderWidth:1 borderColor:[UIColor redColor] cornerRadius:10 borderType:UIBorderSideTypeTop];[_view3 addBorderLineWithBorderWidth:1 borderColor:[UIColor redColor] cornerRadius:10 borderType:UIBorderSideTypeTop];[_view3 addBorderLineWithBorderWidth:1 borderColor:[UIColor redColor] cornerRadius:10 borderType:UIBorderSideTypeLeft];[_view4 addBorderLineWithBorderWidth:2 borderColor:[UIColor redColor] cornerRadius:10 borderType:UIBorderSideTypeLeft];[_view4.layer setMasksToBounds:YES];[_view4.layer setCornerRadius:10];
}
