在 uibutton 上应用阴影使按钮文本模糊

Question

这是我在使用 .XIB 文件创建的 uibutton 上添加阴影的代码

UIBezierPath *shadowPathEndbtn = [UIBezierPath bezierPathWithRect:CGRectMake(0,  self->_navigationView.frame.size.height - 70,[UIScreen mainScreen].bounds.size.width , 2)];
    self->_EndButton.layer.masksToBounds = NO;

    self->_EndButton.layer.shadowColor = [UIColor blackColor].CGColor;
    self->_EndButton.layer.shadowOffset = CGSizeMake(0.0f, 5.0f);
    self->_EndButton.layer.shadowOpacity = 0.7f;
    self->_EndButton.layer.shouldRasterize = YES;
    self->_EndButton.layer.shadowPath = shadowPathForEndbtn.CGPath;

我可以使用此代码设置阴影，但此代码使我的按钮文本看起来模糊。我无法弄清楚这背后的确切原因。任何帮助表示赞赏！

Answer 1

self->_EndButton.layer.masksToBounds = false            
self->_EndButton.layer.shadowColor = [UIColor blackColor].CGColor
self->_EndButton.layer.contentsScale = [[UIScreen mainScreen]scale];
self->_EndButton.layer.shadowOpacity = 0.7f;
self->_EndButton.layer.shadowRadius = 10.0;
self->_EndButton.layer.shadowOffset = CGSizeMake(0,0)

这会产生阴影，而且测试也不模糊

Answer 2

设置按钮背景颜色

self.EndButton.BackgroundColor=[UIColor WhiteColor];
