纯代码适配
视图最基本适配方法介绍
注意：必须先把视图加到父视图再进行适配
注意：右边和底部偏移量为负数

距离父视图上下左右各10个单位

UIView *backGroudView = [[UIView alloc] init];    backGroudView.backgroundColor = [UIColor orangeColor];    [self addSubview:backGroudView];    [backGroudView mas_makeConstraints:^(MASConstraintMaker *make) {        make.top.equalTo(weakSelf.view).offset(10);        make.left.equalTo(weakSelf.view).offset(10);        make.bottom.equalTo(weakSelf.view).offset(-10);        make.right.equalTo(weakSelf.view).offset(-10);    }];

视图靠左上角，宽高固定100

UIView *backGroudView = [[UIView alloc] init];    backGroudView.backgroundColor = [UIColor orangeColor];    [self addSubview:backGroudView];    [backGroudView mas_makeConstraints:^(MASConstraintMaker *make) {        make.top.equalTo(weakSelf.view).offset(10);        make.left.equalTo(weakSelf.view).offset(10);        make.width.mas_equalTo(100);        make.height.mas_equalTo(100);    }];

水平线居中，宽高固定

UIView *backGroudView = [[UIView alloc] init];    backGroudView.backgroundColor = [UIColor orangeColor];    [self addSubview:backGroudView];    [backGroudView mas_makeConstraints:^(MASConstraintMaker *make) {        make.top.equalTo(weakSelf.view).offset(10);        make.width.mas_equalTo(100);        make.height.mas_equalTo(100);       make.centerX.equalTo(weakSelf.view.mas_centerX);    }];

垂直线居中，宽高固定

UIView *backGroudView = [[UIView alloc] init];    backGroudView.backgroundColor = [UIColor orangeColor];    [self addSubview:backGroudView];    [backGroudView mas_makeConstraints:^(MASConstraintMaker *make) {        make.left.equalTo(weakSelf.view).offset(10);        make.width.mas_equalTo(100);        make.height.mas_equalTo(100);      make.centerY.equalTo(weakSelf.view.mas_centerY);    }];

相对父视图居中，宽高固定

//方法一UIView *backGroudView = [[UIView alloc] init];    backGroudView.backgroundColor = [UIColor orangeColor];    [self addSubview:backGroudView];    [backGroudView mas_makeConstraints:^(MASConstraintMaker *make) {        make.width.mas_equalTo(100);        make.height.mas_equalTo(100);       make.centerY.equalTo(weakSelf.view.mas_centerY);       make.centerX.equalTo(weakSelf.view.mas_centerX);    }];//方法二UIView *backGroudView = [[UIView alloc] init];    backGroudView.backgroundColor = [UIColor orangeColor];    [self addSubview:backGroudView];    [backGroudView mas_makeConstraints:^(MASConstraintMaker *make) {        make.size.mas_equalTo(CGSizeMake(200, 200));        make.center.equalTo(weakSelf.view);    }];
