既要温故又要知新...温故而知新,我懂.

在Cocoachina上看到了,UIStackView. 没用过额,试iOS9的新特性.一研究,妈的还挺眼熟.一想,这不和Android上的线性布局一样么..这Android上都用了多少年的东西了.起码我鼓捣基于Android 2.3 SDK的时候有了,详细的就不离题了..

    UILabel *InView1 = [UILabel new];
    
    InView1.text = @"View1";
    
    InView1.backgroundColor = [UIColor lightGrayColor];
    
    NSData * tempArchive = [NSKeyedArchiver archivedDataWithRootObject:InView1];
    
    UILabel *InView2 = [NSKeyedUnarchiver unarchiveObjectWithData:tempArchive];
    
    InView2.text = @"View2";
    
    InView2.backgroundColor = [UIColor grayColor];
    
    UILabel *InView3 = [NSKeyedUnarchiver unarchiveObjectWithData:tempArchive];
    
    InView3.text = @"View3";
    
    InView3.backgroundColor = [UIColor darkGrayColor];
    
    
    UIStackView *usv = [[UIStackView alloc] initWithFrame:CGRectMake(0,self.view.bounds.size.height/2-50, self.view.bounds.size.width, 100)];
    
    //UILayoutConstraintAxisHorizontal,UILayoutConstraintAxisVertical (水平/垂直)
    usv.axis = UILayoutConstraintAxisHorizontal;
    
    //对齐基线
    usv.alignment = UIStackViewAlignmentFill;
    
    //填充方式
    usv.distribution = UIStackViewDistributionFillEqually;
    
    //间距
    usv.spacing = 1.0f;
    
    [self.view addSubview:usv];
    
    [usv addArrangedSubview:InView1];
    
    [usv addArrangedSubview:InView2];
    
    [usv addArrangedSubview:InView3];
