v.snp_makeConstraints{ (make)in@H_502_4@

由于swift和oc语法不一样 equalTo(self.view)是传入参数 @H_502_4@

make.top.equalTo(self.view).offset(100)@H_502_4@

make.left.equalTo(self.view).offset(100)@H_502_4@

make.right.equalTo(self.view).offset(-100)@H_502_4@

make.bottom.equalTo(self.view).offset(-100)@H_502_4@

由于swift和oc语法不一样 equalTo()是先调用get方法@H_502_4@

v.mas_makeConstraints{ (make)in@H_502_4@

make.top.equalTo()(self.view).setOffset(100)@H_502_4@

make.left.equalTo()(self.view).setOffset(100)@H_502_4@

make.right.equalTo()(self.view).setOffset(100)@H_502_4@

make.bottom.equalTo()(self.view).setOffset(100)@H_502_4@

}@H_502_4@
