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

#import"WJFlowLabel.h"

@implementationWJFlowLabel

- (id)initWithFrame:(CGRect)frame {

if(self= [superinitWithFrame:frame]) {
