iOS绘制图片与文字

#####绘制图片与文字 #####1.绘制图片，直接代码说明

• 加载图片

  #pragma mark - 小黄人
  -(void) drawImage:(CGRect) rect{
      UIImage *image=[UIImage imageNamed:@"黄人"];
      //图片有可能显示不全，由于绘制的图片与实际所给图片同样大
      //    [image drawAtPoint:CGPointZero];
      //将整个图片放置到view中显示
      [image drawInRect:rect];
  }

  #pragma mark - 花图
  -(void) drawImage2:(CGRect) rect{
      UIImage *image=[UIImage imageNamed:@"001"];
      //平铺
      [image drawAsPatternInRect:rect];
  }

  #pragma mark - 花图裁切
  -(void) drawImage3:(CGRect) rect{
      UIImage *image=[UIImage imageNamed:@"001"];
      UIRectClip(CGRectMake(0, 0, 50, 50));
      //平铺
      [image drawAsPatternInRect:rect];
  }

• 绘制文字

  #pragma mark - 绘制文字
  -(void) drawText:(CGRect) rect{
  
      NSString *str=@"绘制文字sssssssssssssssssssssssssssssssss";
  
      NSMutableDictionary *textDic=[NSMutableDictionary dictionary];
      textDic[NSFontAttributeName]=[UIFont systemFontOfSize:30];
      textDic[NSForegroundColorAttributeName]=[UIColor redColor];
      textDic[NSStrokeWidthAttributeName]=@3;
      //// UIColor, default nil: same as foreground color
      textDic[NSStrokeColorAttributeName]=[UIColor blueColor];
      NSShadow *shade=[[NSShadow alloc]init];
      shade.shadowBlurRadius=1;
      shade.shadowColor=[UIColor redColor];
      shade.shadowOffset=CGSizeMake(2, 2);
      textDic[NSShadowAttributeName]=shade;
      //这个不会换行
  //    [str drawAtPoint:CGPointZero withAttributes:textDic];
      [str drawInRect:rect withAttributes:textDic];
  }

• 最后加上

  #pragma mark - drawRect
  - (void)drawRect:(CGRect)rect {
  //    [self drawImage:rect];
  //    [self drawImage2:rect];
  //    [self drawImage3:rect];
      [self drawText:rect];
  
  }
