【问题描述】:
我有一个 UITableView,其中的单元格有一些 UITableViewRowActions。我们的模型使用较小的字体和较窄的 UITableViewRowAction 按钮。是否可以以任何方式更改 UITableViewRowAction 的字体和/或大小?
Apple's documentation 表示这是不可能的,因此我想问是否有其他方法。

【解决方案1】:
UITableViewCell 由backgroundView 和contentView 组成,覆盖backgroundView 您可以将UIButtons 作为subViews 添加到您的backgroundView 并添加一个UIPanGestureRecognizer 在单元格上方。因此,当您水平平移单元格时,只有 contentView 移动,UIButtons 会暴露。所以在cellForRowAtIndexPath
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *myCell;
myCell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:@"YOUR_IDENTIFIER"];
//adding button to a view that is added as the backgroundview
UIView *cellBackgroundUtilityView=[[UIView alloc]initWithFrame:myCell.frame];
[cellBackgroundUtilityView addSubview:<your button>]
[myCell setBackgroundView: cellBackgroundUtilityView]
//adding a gesture recognizer
UIPanGestureRecognizer *panningCell=[[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(yourPanningTableViewCellMethod:)];
[panningCell setDelegate:self];
[myCell addGestureRecognizer:panningCell];
}
当手势识别器被激活时,这个方法会被调用
-(void) yourPanningTableViewCellMethod:(id)sender
{
// gesture recognizer is active
UIPanGestureRecognizer* recognizer=(UIPanGestureRecognizer *) sender;
UITableViewCell *tableCell=(UITableViewCell *)recognizer.view;
//moving the contentView horizontally according to pan
[tableCell.contentView setFrame:CGRectMake([recognizer translationInView:self.view].x, tableCell.contentView.frame.origin.y, tableCell.frame.size.width, tableCell.frame.size.height)];
}
当按钮的选择器被调用时
-(void)yourBackgroundViewButtonWasPressed
{
// button was pressed
// move content view of the cell back to origin
[tableCell.contentView setFrame:CGRectMake(0.0, tableCell.contentView.frame.origin.y, tableCell.frame.size.width, tableCell.frame.size.height)];
//do your stuff
}
