Masonry应用【美图秀秀首页界面自动布局】

Masonry在此实现时候，并没有比NSLayoutConstraint简单，相反我觉得还不如NSLayoutConstraint。
[self.topView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.view.mas_top);
make.right.equalTo(self.view.mas_right).with.offset(-);
make.width.equalTo(@);
make.height.equalTo(@);
}];
[btnSetting mas_makeConstraints:^(MASConstraintMaker *make) {
make.bottom.equalTo(self.view.mas_bottom).with.offset(-);
make.right.equalTo(self.view.mas_right).with.offset(-);
make.width.equalTo(@);
make.height.equalTo(btnSetting.mas_width);
}];
[self.scrolleView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(image.mas_bottom);
make.left.equalTo(self.view.mas_left);
make.width.equalTo(@(WIDTH-));
make.height.equalTo(@(HEIGHT - - ));
}];
下面是使用NSLayoutConstraint的代码实现
[NSLayoutConstraint constraintWithItem:self.topView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeTop multiplier:1.0 constant:],
[NSLayoutConstraint constraintWithItem:self.topView attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeRight multiplier:1.0 constant:-],
[NSLayoutConstraint constraintWithItem:self.topView attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:],
[NSLayoutConstraint constraintWithItem:self.topView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:], [NSLayoutConstraint constraintWithItem:btnSetting attribute:NSLayoutAttributeBottom relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeBottom multiplier:1.0 constant:-],
[NSLayoutConstraint constraintWithItem:btnSetting attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeRight multiplier:1.0 constant:-],
[NSLayoutConstraint constraintWithItem:btnSetting attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:],
[NSLayoutConstraint constraintWithItem:btnSetting attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:btnSetting attribute:NSLayoutAttributeWidth multiplier:1.0 constant:], [NSLayoutConstraint constraintWithItem:self.scrolleView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:image attribute:NSLayoutAttributeBottom multiplier:1.0 constant:],
[NSLayoutConstraint constraintWithItem:self.scrolleView attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeLeft multiplier:1.0 constant:],
[NSLayoutConstraint constraintWithItem:self.scrolleView attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:WIDTH],
[NSLayoutConstraint constraintWithItem:self.scrolleView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:HEIGHT - - ]
至于使用哪种布局库，自行斟酌。。。。
