Add the weight of each view to the AutoLayout

The weight of each view is added to the AutoLayout so that the relationship between them is clearer, such as:

DoubleIconviewweight =1; DoubleTitlelabelweight = A; DoubleTimelabelweight =3;     DoubleStandardweigth =Iconviewweight; DoubleIconviewweightratio = iconviewweight/standardweigth; DoubleTitilelabelwightratio = titlelabelweight/standardweigth; DoubleTimelabelwightratio = timelabelweight/standardweigth; UIView*standardview =_iconview;nsdictionary*views =nsdictionaryofvariablebindings (_iconview, _titilelabel, _timelabel, Bgimageview);Nslayoutconstraint *constraint =[Nslayoutconstraint constraintwithitem:_iconview att Ribute:nslayoutattributewidth Relatedby:nslayoutrelatione                                                                  Qual Toitem:standardview                                                                 Attribute:nslayoutattributewidth MULTIPLIER:ICONVIEWWEIGHTRATIO constant:0.0f];        [Self addconstraint:constraint]; Constraint=[Nslayoutconstraint Constraintwithitem:_titilelabel Attribute:nslayoutat                                                 Tributewidth relatedby:nslayoutrelationequal                                             Toitem:standardview Attribute:nslayoutattributewidth Multiplier:titilelabelwightratio Constan T:0.0f];    [Self addconstraint:constraint]; Constraint=[Nslayoutconstraint Constraintwithitem:_timelabel attribute:nslayoutattr                                                 Ibutewidth relatedby:nslayoutrelationequal                                             Toitem:standardview Attribute:nslayoutattributewidth Multiplier:timelabelwightratio constant:

The code is more brief, but this applies to some specific situations
