1.图片头像切成圆【不是半径的话 不是正圆】
self.imgvHead.clipsToBounds =
YES;
self.imgvHead.layer.cornerRadius
= self.imgvHead.bounds.size.height/2;
self.imgvHead.layer.borderWidth
= 0.5f;
self.imgvHead.layer.borderColor
= [UIColor colorWithRed:0
green:0
blue:0
alpha:0.3].CGColor;
2.UILabel底部显示一条线
NSMutableAttributedString *str = [[NSMutableAttributedString
alloc]
initWithString:self.lblCheckDetail.text];
NSRange strRange = {0,[str
length]};
[str addAttribute:NSUnderlineStyleAttributeName
value:[NSNumber
numberWithInteger:NSUnderlineStyleSingle]
range:strRange];
[self.lblCheckDetail
setAttributedText:str];
3.自定义一个透明度渐变的效果
UIColor *colorOne = [UIColor
colorWithRed:(33/255.0)
green:(33/255.0)
blue:(33/255.0)
alpha:0.0];
UIColor *colorTwo = [UIColor
colorWithRed:(33/255.0)
green:(33/255.0)
blue:(33/255.0)
alpha:1.0];
NSArray *colors = [NSArray
arrayWithObjects:(id)colorOne.CGColor, colorTwo.CGColor,
nil];
NSNumber *stopOne = [NSNumber
numberWithFloat:0.0];
NSNumber *stopTwo = [NSNumber
numberWithFloat:1.0];
NSArray *locations = [NSArray
arrayWithObjects:stopOne, stopTwo,
nil];
CAGradientLayer *headerLayer = [CAGradientLayer
layer];
headerLayer.colors = colors;
headerLayer.locations = locations;
CGFloat width =
self.viewGradualAlpha.bounds.size.width
+ SCREEN_WIDTH -
self.cellimgvTop.bounds.size.width;
CGFloat height=
self.viewGradualAlpha.bounds.size.height;
headerLayer.frame =
CGRectMake(0,
0, width, height);
[self.viewGradualAlpha.layer
insertSublayer:headerLayer
atIndex:0];
