用UISlider控制自定义tableViewCell中字体的大小

字体随滑杆的滑动而变大或变小。用滑杆去控制字体的大小很简单,但用字体去控制自定义tableViewcell内字体的大小也很简单,只不过第一次做的时候可能要摸索一下,这里我就简单的给大家演示一下:

这是一个按钮,点击按钮弹出一个带有slider的view

- (IBAction)btnClick:(id)sender
{
    UIView *sliderView = [[UIView alloc]initWithFrame:CGRectMake(self.view.frame.size.width-188, 70, 150, 120)];
    sliderView.backgroundColor = [UIColor blackColor];
    [self.view addSubview:sliderView];
    
    _setField1 = [[UITextField alloc]initWithFrame:CGRectMake(60, 72, 60, 30)];
    _setField1.backgroundColor = [UIColor clearColor];
    _setField1.textColor = [UIColor whiteColor];
    _setField1.font = [UIFont systemFontOfSize:12];
    [sliderView addSubview:_setField1];
    UISlider *fontSlider = [[UISlider alloc]initWithFrame:CGRectMake(5,77 , 140, 60)];
    fontSlider.minimumValue = 10;
    fontSlider.maximumValue = 20;
    fontSlider.value = 10;
    _showFontValue = fontSlider.value;
    _setField1.text = [NSString stringWithFormat:@"%ld",(long)_showFontValue];
    [fontSlider addTarget:self action:@selector(ChangeFont:) forControlEvents:UIControlEventValueChanged];
    [sliderView addSubview:fontSlider];
}

这是滑动滑杆所触发的方法:

-(void)ChangeFont:(UISlider *)slider
{
   _font = slider.value;
    
    [_tableview reloadData];
    NSLog(@"============%@",cell.cell1titlelable.font);
}

这是自定义cell中要添加的代码:

 cell.cell1titlelable.font = [UIFont systemFontOfSize:_font];
 cell.cell1soucelable.font = [UIFont systemFontOfSize:_font];
 cell.cell1incollable.font = [UIFont systemFontOfSize:_font];
