如何以编程方式将约束添加到tableView单元格的默认textLabel和annexView

Question

I have a cell and since i wanted the default behaviour i am using the following way -

returnCell.textLabel.text = @"Some long text Some long text";
returnCell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;
returnCell.textLabel.numberOfLines = 0;

UISwitch *toggleSwitch = [[UISwitch alloc] initWithFrame:CGRectZero];
returnCell.accessoryView = toggleSwitch;

[returnCell.contentView setTranslatesAutoresizingMaskIntoConstraints:NO];
[returnCell.textLabel setTranslatesAutoresizingMaskIntoConstraints:NO];

[returnCell addVisualConstraints:@"H:|[contentView]|"
                            forViews:@{@"contentView":returnCell.contentView}];
[returnCell addVisualConstraints:@"V:|[contentView]|"
                            forViews:@{@"contentView":returnCell.contentView}];

Now the problem that i have is, the text if small works fine but if it's long it goes behind the switch....

Now my question is how do i avoid this and add constraints to solve this problem between my textLabel and accessoryView(UISwitch) both of which are defalt and not added as subView to contentView of cell??

Thanks in advance!!! Please help.

枚举contentView约束，直到找到带有textLabel的 尾随约束为止，并增加/减小它对第一个项的常数，直到它离开开关（accessoryView）
