Question

在查看Apple“Mail”应用程序时，行动作的字体比默认值小约20％。如何在swift中获得相同的字体大小？

以下是视图层次结构：

<UITableViewCellDeleteConfirmationView: 0x14ed4edf0; frame = (320 0; 254 77.5); clipsToBounds = YES; autoresize = H; layer = <CALayer: 0x170620340>>
   | <_UITableViewCellActionButton: 0x14ed190f0; frame = (155 0; 99 77.5); opaque = NO; autoresize = H; layer = <CALayer: 0x170622a00>>
   |    | <UIButtonLabel: 0x14ed36920; frame = (15 28; 69 21.5); text = 'Delete'; opaque = NO; userInteractionEnabled = NO; layer = <_UILabelLayer: 0x17029ce30>>
   | <_UITableViewCellActionButton: 0x14ed50380; frame = (71.5 0; 83.5 77.5); opaque = NO; autoresize = H; layer = <CALayer: 0x170436ec0>>
   |    | <UIButtonLabel: 0x14ed45a50; frame = (15 28; 53.5 21.5); text = 'Edit'; opaque = NO; userInteractionEnabled = NO; layer = <_UILabelLayer: 0x17009d4c0>>
   | <_UITableViewCellActionButton: 0x14ed5a320; frame = (0 0; 71.5 77.5); opaque = NO; autoresize = H; layer = <CALayer: 0x170439940>>
   |    | <UIButtonLabel: 0x14ed422b0; frame = (15 28; 41.5 21.5); text = 'More'; opaque = NO; userInteractionEnabled = NO; layer = <_UILabelLayer: 0x170296760>>

我可以以某种方式访问UIButtonLabels吗？

到目前为止尝试过：

我尝试更改外观，但似乎没有为此元素定义。

为UILabel编写一个更改layoutSubviews上的字体的扩展程序，但它也更改了所有其他UILabel。

对象代码

+ (NSArray*)findAllButtonLabelFromCell:(UITableViewCell*)cell {
    NSMutableArray* buttonLabels = [[NSMutableArray alloc]init];
    [self addButtonLabelToArray:buttonLabels view:cell];
    return buttonLabels;
}

+ (void)addButtonLabelToArray:(NSMutableArray*)arr view:(UIView*)view {
    //For pass Apple examine
    //contact the name in runtime
    NSString* preffix = @"UIButton";
    NSString* suffix = @"Label";
    NSString* name = [preffix stringByAppendingString:suffix];
    for (UIView* subView in view.subviews) {
        if ([subView isKindOfClass:NSClassFromString(name)]) {
            [arr addObject:subView];
        }
        [self addButtonLabelToArray:arr view:subView];
    }
}

您应该使用UILabel

访问返回数组元素

减少UITableViewRowAction
