用autolayout设置相同水平位置上的两个view的问题

我在写一个自定义的 UITabelViewCell 的时候遇到了subview排列的问题。
自定义的cell如下图所示：

我想要的效果是：timeLabel的内容能完全显示，然后titleLabel右边距离timeLabel 10px，titleLabel的宽度根据以上约束自动确定。我的代码如下：


 [self.contentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:[timeLabel]-15-|" options:0 metrics:nil views:views]];
[self.contentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:[timeLabel(>=40)]-15-|" options:0 metrics:nil views:views]];
[self.contentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:[timeLabel(<=70)]-15-|" options:0 metrics:nil views:views]];
[self.contentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:[titleLabel]-10-[timeLabel]" options:NSLayoutFormatAlignAllCenterY metrics:nil views:views]];

但看起来显然不靠谱啊，请问大家该怎样解决，谢谢。

手写的代码参考：


 UIImageView *myImageView=[[UIImageView alloc]init];
myImageView.backgroundColor=[UIColor groupTableViewBackgroundColor];
[self.view addSubview:myImageView];

UILabel *titleLabel=[[UILabel alloc]init];
titleLabel.text=@"bababababbababababbababababbabababab";
[self.view addSubview:titleLabel];

UILabel *timeLabel=[[UILabel alloc]init];
timeLabel.text=@"昨天 23:58";//15小时前,前天
timeLabel.textAlignment=NSTextAlignmentRight;
[self.view addSubview:timeLabel];



[myImageView mas_makeConstraints:^(MASConstraintMaker *make) {
    make.top.equalTo(self.view.mas_top).offset(30);
    make.leading.equalTo(self.view.mas_left).offset(10);
    make.width.mas_equalTo(80);
    make.height.mas_equalTo(80);
}];

[titleLabel mas_makeConstraints:^(MASConstraintMaker *make) {
    make.leading.equalTo(myImageView.mas_trailing).offset(10);
    make.top.equalTo(self.view.mas_top).offset(40);
    make.height.mas_equalTo(30);
    make.trailing.equalTo(timeLabel.mas_leading).offset(-10);
}];

[timeLabel mas_makeConstraints:^(MASConstraintMaker *make) {
    make.trailing.equalTo(self.view.mas_trailing).offset(-10);
    make.top.equalTo(self.view.mas_top).offset(40);
    make.height.mas_equalTo(30);
    make.width.mas_greaterThanOrEqualTo(34);
    make.width.mas_lessThanOrEqualTo(85);//timelabel宽度的最大最小值根据你的font来调整算出来
}];
