如何在单元格内容视图和分隔符之间增加间距？
我正在尝试实现以下所示的设计，但是占位符为“输入您的显示名称”的UITextField过于靠近分隔符。我试过根据节和行更改cellHeightForIndex，但是没有达到预期的效果。如何在内容视图和分隔符之间添加间距？
#define kCellSeparatorTag 100

该问题可能是因为您没有在单元格上设置detailTextLabel属性。尝试将其设置为空格字符并向上移动子视图。
在您的case 1中添加：
cell.detailTextLabel.text = @" ";
还可以稍微改变子视图的位置（y从40更改为20）：
self.displayNameTextField = [[UITextField alloc] initWithFrame:CGRectMake(15, 20, 375, 30)];
我注意到的另一件事是您以非标准方式使用switch语句。而不是这样做：
switch (expression) {
case n:
statements;
break;
default:
break;
}
switch (expression) {
case n+1:
statements;
break;
default:
break;
}
这样做：
switch (expression) {
case n:
statements;
break;
case n+1:
statements;
break;
case n+2:
statements;
break;
default:
break;
}
