Create UILable at runtime and set autolayout programatically related to each other - ios

Question

I have a UIView in UITableViewCell. I am getting a array of names from service and I want to create a UILabel in a for loop inside a UIView which is in UITableViewCell according to the text width.
I have done this at my end but the problem is that I want to check if the label which is being created is having a width greater than the space remaining in its superview, then it should be created below the first line just like word wrapping of text in UILabel.
What I have done is, I have created a sample of code
-(void)addADaynamicViw
{
[self.vwContainer setTranslatesAutoresizingMaskIntoConstraints:false];
UILabel *lblPrevious;
int totalWidth;
for (int i=0; i<8; i++) {
UILabel *lbl=[[UILabel alloc]init];
//[lbl setFrame:CGRectMake(0, 0, 30, 50)];
[lbl setNumberOfLines:0];
[lbl setBackgroundColor:[UIColor greenColor]];
[lbl setTranslatesAutoresizingMaskIntoConstraints:false];
[lbl setText:[NSString stringWithFormat:#"Label Num %d",i]];
[self.vwContainer addSubview:lbl];
NSLayoutConstraint *top;
top=[NSLayoutConstraint constraintWithItem:lbl attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationGreaterThanOrEqual toItem:self.vwContainer attribute:NSLayoutAttributeTop multiplier:1.0 constant:0];
NSLayoutConstraint *left;
if (lblPrevious) {
CGSize size = lblPrevious.intrinsicContentSize;
NSLog(#"intrinzik content size =%f",size.width);
left =[NSLayoutConstraint constraintWithItem:lbl attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationLessThanOrEqual toItem:lblPrevious attribute:NSLayoutAttributeLeft multiplier:1 constant:size.width+2];
}
else
{
left=[NSLayoutConstraint constraintWithItem:lbl attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationLessThanOrEqual toItem:self.vwContainer attribute:NSLayoutAttributeLeft multiplier:1 constant:0];
}
NSLayoutConstraint *width=[NSLayoutConstraint constraintWithItem:lbl attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationGreaterThanOrEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:10];
NSLayoutConstraint *height=[NSLayoutConstraint constraintWithItem:lbl attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:50];
NSLayoutConstraint *bottom=[NSLayoutConstraint constraintWithItem:lbl attribute:NSLayoutAttributeBottom relatedBy:NSLayoutRelationEqual toItem:self.vwContainer attribute:NSLayoutAttributeBottom multiplier:1.0 constant:0];
NSLayoutConstraint *right=[NSLayoutConstraint constraintWithItem:lbl attribute:NSLayoutAttributeTrailing relatedBy:NSLayoutRelationLessThanOrEqual toItem:self.vwContainer attribute:NSLayoutAttributeTrailing multiplier:1.0 constant:0];
[self.vwContainer addConstraint:left];
[self.vwContainer addConstraint:bottom];
[self.vwContainer addConstraint:width];
[self.vwContainer addConstraint:top];
[self.vwContainer addConstraint:height];
[self.vwContainer addConstraint:right];
lblPrevious=lbl;
CGSize size = lblPrevious.intrinsicContentSize;
totalWidth+=size.width;
}
[self.vwContainer layoutIfNeeded];
[self.vwContainer updateConstraintsIfNeeded];
}
This line of code is creating the label programmatically after the end of previous label, but I want that if the label which is being created does not fit in its superview then it should increase the height of its superview and should start from 0 of its superview, but below the first label.
