ios purelayout--基础使用--进阶使用--看这就够了

//******************************基础设置--start*********************************
//一.视图本身
//1.设置高度
[self.namePhoneLB autoSetDimension:ALDimensionHeight toSize:20];
//2.设定宽高
[self.iconImageView autoSetDimensionsToSize:CGSizeMake(45, 45)];

//二.父子视图
//1.距离父视图某边距10
[self.iconImageView autoPinEdgeToSuperviewEdge:ALEdgeLeft withInset:10];
//2.Y轴居中
[self.iconImageView autoAlignAxisToSuperviewAxis:ALAxisHorizontal];
//3.设置四边约束忽略某个属性
ALEdgeInsets defInsets = ALEdgeInsetsMake(17.5,10,17.5,10);//上左下右
[self.agreeBtn autoPinEdgesToSuperviewEdgesWithInsets:defInsets excludingEdge:ALEdgeLeft];

//三.兄弟视图
//1.设置该视图 的左边距离 到其他视图的右边 10
[self.namePhoneLB autoPinEdge:ALEdgeLeft toEdge:ALEdgeRight ofView:self.iconImageView  withOffset:10];
//2.设置该视图与其他视图 同X值
[self.descriseLB autoAlignAxis:ALAxisVertical toSameAxisOfView:self.namePhoneLB];
//3.设置该视图与其他视图 等宽
[self.descriseLB autoMatchDimension:ALDimensionWidth toDimension:ALDimensionWidth ofView:self.namePhoneLB];

//清除约束
for (NSLayoutConstraint *contrain in self.tempView.superview.constraints) {
    if ([contrain isEqual:self.tempContraint]) {
        [self.tempView.superview removeConstraint:contrain];
    }
}
//约束返回值，修改返回值即可修改约束
self.tempContraint = [self.tempView autoPinEdgeToSuperviewEdge:ALEdgeBottom withInset:0];
