textview对象.layer.borderColor = UIColor.grayColor.CGColor;

textview对象.layer.borderWidth = 5; //必须设置宽度，否则加不上

textview对象.layer.cornerRadius = 4;//圆角弧度

UIButton *signBtn = [UIButton buttonWithType:UIButtonTypeCustom];
signBtn.frame = CGRectMake(0, 0, 80, 40);
[signBtn.layer setMasksToBounds:YES];
[signBtn.layer setCornerRadius:10.0]; //设置矩形四个圆角半径
[signBtn.layer setBorderWidth:1.0]; //边框宽度
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();

CGColorRef colorref = CGColorCreate(colorSpace,(CGFloat[]){ 1, 0, 0, 1 });

[signBtn.layer setBorderColor:colorref];//边框颜色

[signBtn setTitle:@"还原" forState:UIControlStateNormal];//button title

[signBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];//title color

[signBtn addTarget:self action:@selector(buttonDonwRecover:) forControlEvents:UIControlEventTouchUpInside];//button 点击回调方法

signBtn.backgroundColor = [UIColor whiteColor];

- (void)buttonDonwRecover:(id)sender

{

UIButton *btn = (UIButton *)sender;

}

//加下划线

NSMutableAttributedString *str = [[NSMutableAttributedStringalloc] initWithString:self.resgiterButton.titleLabel.text];

NSRange strRange = {0,[strlength]};

[str addAttribute:NSUnderlineStyleAttributeNamevalue:[NSNumbernumberWithInteger:NSUnderlineStyleSingle]range:strRange];

[self.resgiterButtonsetAttributedTitle:str forState:UIControlStateNormal];
