今天分享自己掌握的几种UIlabel ,大家有更多的label请分享给我哟
1:内边距,自适应的label ,这个label主要是用于内边距同时要Masonry进行适配的时候使用
InsetLabel.h
@interfaceInsetLabel :UILabel
//用于设置Label的内边距
@property(nonatomic)UIEdgeInsetsneiinsets;
//初始化方法一
-(id) initWithFrame:(CGRect)frame andInsets: (UIEdgeInsets) neiinsets;
//初始化方法二
-(id) initWithInsets: (UIEdgeInsets) neiinsets;
@end
InsetLabel.m
#import"InsetLabel.h"
@implementationInsetLabel
//初始化方法一
-(id) initWithFrame:(CGRect)frame andInsets:(UIEdgeInsets)neiinsets {
self= [superinitWithFrame:frame];
if(self){
self.neiinsets= neiinsets;
}
returnself;
}
//初始化方法二
-(id) initWithInsets:(UIEdgeInsets)neiinsets {
self= [superinit];
if(self){
self.neiinsets= neiinsets;
}
returnself;
}
//重载drawTextInRect方法
-(void) drawTextInRect:(CGRect)rect {
return[superdrawTextInRect:UIEdgeInsetsInsetRect(rect,self.neiinsets)];
}
- (CGRect)textRectForBounds:(CGRect)bounds limitedToNumberOfLines:(NSInteger)numberOfLines {
UIEdgeInsetsinsets =self.neiinsets;
CGRectrect = [supertextRectForBounds:UIEdgeInsetsInsetRect(bounds, insets)
limitedToNumberOfLines:numberOfLines];
rect.origin.x-= insets.left;
rect.origin.y-= insets.top;
rect.size.width+= (insets.left+ insets.right);
rect.size.height+= (insets.top+ insets.bottom);
returnrect;
}
@end
2:描边的label ,以及虚线label
WJFOutlineLabel.h
@interfaceWJFOutlineLabel : UILabel
/**描多粗的边*/
@property(nonatomic,assign) NSInteger outLineWidth;
/**外轮颜色*/
@property(nonatomic,strong) UIColor *outLinetextColor;
/**里面字体默认颜色*/
@property(nonatomic,strong) UIColor *labelTextColor;
@end
WJFOutlineLabel.m
#import"WJFOutlineLabel.h"
@implementationWJFOutlineLabel
- (void)drawTextInRect:(CGRect)rect {
CGSize shadowOffset =self.shadowOffset;
UIColor *textColor =self.textColor;
CGContextRef c = UIGraphicsGetCurrentContext();
CGContextSetLineWidth(c,self.outLineWidth);
CGContextSetLineJoin(c, kCGLineJoinRound);
CGContextSetTextDrawingMode(c, kCGTextStroke);
self.textColor =self.outLinetextColor;
[superdrawTextInRect:rect];
self.textColor = textColor;
CGContextSetTextDrawingMode(c, kCGTextFill);
[superdrawTextInRect:rect];
self.shadowOffset = shadowOffset;
}
//虚线的label
-(void)dottedLineWithView:(UIView*)dottedView{
CAShapeLayer*border = [CAShapeLayerlayer];
border.strokeColor= [UIColorredColor].CGColor;
border.fillColor=nil;
border.path= [UIBezierPathbezierPathWithRect:dottedView.bounds].CGPath;
border.frame= dottedView.bounds;
border.lineWidth=1.f;
border.lineCap=@"square";
border.lineDashPattern=@[@4,@2];
[dottedView.layeraddSublayer:border];
}
@end
3:辉光效果的Label
WJFlowLabel.h
@interfaceWJFlowLabel :UILabel
/**
*Glow size, default is 0.f.
*/
@property(nonatomic)CGFloatglowSize;
/**
*Glow color, default is clear color.
*/
@property(nonatomic,strong)UIColor*glowColor;
/**
*Inner glow size, default is 0.f.
*/
@property(nonatomic)CGFloatinnerGlowSize;
/**
*Inner glow color, default is clear color.
*/
@property(nonatomic,strong)UIColor*innerGlowColor;
@end
WJFlowLabel.m
