Used to record the last created Uilabel

UILabel *lastlabel = nil;

for (int i = 0; i < 9; i++) {

UILabel *label = [UILabel new];

Label.textalignment = Nstextalignmentcenter;

Label.text = [NSString stringwithformat:@ "~%d~", I];

[Self.view Addsubview:label];

[Label mas_makeconstraints:^ (Masconstraintmaker *make) {

Set height

Make.height.offset (40.0f);

Calculates the formula at the top of the distance 60 = the height of the previous distance above the top + Uilabel

Float Coltop = (+ I/3 * 60.0f);

Make.top.offset (Coltop);

When the left column is the distance from the parent view to the left 20

if (i%3 = = 0) {

Make.left.offset (20.0f);

}else{

When the middle column was on the right side of the previous Uilabel, add 20 distances and set the equal height

Make.width.equalTo (Lastlabel.mas_width);

Make.left.equalTo (lastlabel.mas_right). Offset (20.0f);

}

//When it is the rightmost column, the distance from the right parent view is 20 because it is left so 20 control bottom is negative!

if (i%3 = = 2) {

Make.right.offset ( -20.0f);

}

}];

LastLabel = label;

}
