目的是讓label的字體貼上面。

? ? self.textLabel.frame = CGRectMake(BGAdaptedWidth(19),? CGRectGetMaxY(self.titleLabel.frame) + BGAdaptedHeight(32), BGAdaptedWidth(302), BGAdaptedWidth(270));

? ? self.textLabel.text= BGLocaltring(@"31313151313131313213131一大段落文字");

? ? self.textLabel.numberOfLines = 0;

? ? [self.textLabel sizeToFit];

? ? self.textLabel.mj_w = BGAdaptedWidth(302);

? ? [self.textLabel sp_setLineSpace: BGAdaptedHeight(11)];//設(shè)置行間距

設(shè)置button的兩個(gè)圓角

? ? UIBezierPath * path = [UIBezierPath bezierPathWithRoundedRect:self.agreeButton.bounds byRoundingCorners:UIRectCornerBottomLeft|UIRectCornerBottomRight cornerRadii:CGSizeMake(BGAdaptedWidth(10), BGAdaptedWidth(10))];

? ? CAShapeLayer * layer = [[CAShapeLayer alloc] init];

? ? layer.frame=self.agreeButton.bounds;

? ? layer.path= path.CGPath;

? ? self.agreeButton.layer.mask= layer;
