如何借助AutoLayout在自定义UITableviewCell中添加自定义UIView（xib）？

Question

I have one View Controller in which I have one UITableView .

I have used custom UITableviewCell with xib in that UITableView .

Now I have one UIView with xib and I want to add that UIView's object in custom UITableViewCell with the help of AutoLayout.

I added that UIView successfully in custom UITableViewCell , but that UIView is so much big and it is not fitting in my custom UITableViewCell .

I know that UIView can be fit properly in custom UITableViewCell with the help of AutoLayout, but I don't know How, because I am new to AutoLayout.

In My Custom UITableViewCell

CustomAlertCell.m//this is my custom UITableViewCell class

-(void)addCustomView_ForRow:(int)theRow
{
    JobAlertCell_View *vwJob = [[JobAlertCell_View alloc] initFromNibFile:@"JobAlertCell_View"];
   vwJob.frame = CGRectMake(0, 118, vwJob.frame.size.width, vwJob.frame.size.height);
   [self addSubview:vwJob];
}

Here my vwJob.frame.size.height = 90 , but in device it is much bigger that the size i want.

Thanks.

You can add width and height constraint using below code

    -(void)addCustomView_ForRow:(int)theRow
    {
       JobAlertCell_View *vwJob = [[JobAlertCell_View alloc] initFromNibFile:@"JobAlertCell_View"];
       [self addSubview:vwJob];

        [self addConstraint:[NSLayoutConstraint constraintWithItem:vwJob
                                                       attribute:NSLayoutAttributeHeight
                                                       relatedBy:NSLayoutRelationEqual
                                                          toItem:nil
                                                       attribute:NSLayoutAttributeNotAnAttribute
                                                      multiplier:1.0
                                                        constant:100.0]];
        [self addConstraint:[NSLayoutConstraint constraintWithItem:vwJob
                                                       attribute:NSLayoutAttributeWidth
                                                       relatedBy:NSLayoutRelationEqual
                                                          toItem:nil
                                                       attribute:NSLayoutAttributeNotAnAttribute
                                                      multiplier:1.0
                                                        constant:100.0]];
        [self layoutIfNeeded];

    }
