网上看了很多 自己的代码里面最终还是采用了自己的办法
我采用安全区域做
首先在基类自定义了个vkview 如果非SB或者xib做的话 就可以用到
- (UIView*)vkView {
if(!_vkView) {
if(@available(iOS11.0, *)) {
self.view.backgroundColor=VKHexColor(app_White_Color);
_vkView= [[UIViewalloc]init];
[self.viewaddSubview:_vkView];
[_vkViewmas_makeConstraints:^(MASConstraintMaker*make) {
make.top.mas_equalTo(self.view.mas_safeAreaLayoutGuideTop);
make.bottom.mas_equalTo(self.view.mas_safeAreaLayoutGuideBottom);
make.left.mas_equalTo(self.view.mas_safeAreaLayoutGuideLeft);
make.right.mas_equalTo(self.view.mas_safeAreaLayoutGuideRight);
}];
}else{
//适配状态栏
if (self.navigationController.navigationBarHidden || !self.navigationController) {
self.view.backgroundColor=VKHexColor(app_White_Color);
_vkView= [[UIViewalloc]init];
[self.viewaddSubview:_vkView];
[_vkViewmas_makeConstraints:^(MASConstraintMaker*make) {
make.top.mas_equalTo(self.view).offset(20);
make.bottom.left.right.mas_equalTo(self.view);
}];
}else{
_vkView=self.view;
}
}
_vkView.backgroundColor = VKHexColor(app_White_Color);
}
return _vkView;
}
用vkview的时候 记得在点语法之前 告知导航栏隐藏的情况
二 ，刘海屏有时候需要判断
1》window.safeAreaLayoutGuide.layoutFrame.size.height !=kScreenHeight kScreenHeight是宏屏高
2》[UIApplication sharedApplication].keyWindow.safeAreaInsets.bottom > 0
三，有时候需要弹框 需要精确定位
self是封装的弹框view
[[[UIApplication sharedApplication].keyWindow.subviews objectAtIndex:0] addSubview:self];
if(@available(iOS11.0, *)) {
[selfmas_makeConstraints:^(MASConstraintMaker*make) {
make.top.mas_equalTo(_toPoint.y);
make.left.mas_equalTo([[UIApplication sharedApplication].keyWindow.subviews objectAtIndex:0].mas_safeAreaLayoutGuideLeft);
make.right.mas_equalTo([[UIApplication sharedApplication].keyWindow.subviews objectAtIndex:0].mas_safeAreaLayoutGuideRight);
make.bottom.mas_equalTo([[UIApplication sharedApplication].keyWindow.subviews objectAtIndex:0].mas_safeAreaLayoutGuideBottom);
}];
}else{
[selfmas_makeConstraints:^(MASConstraintMaker*make) {
make.top.mas_equalTo(_toPoint.y);
make.left.mas_equalTo([[UIApplication sharedApplication].keyWindow.subviews objectAtIndex:0].mas_left);
make.right.mas_equalTo([[UIApplication sharedApplication].keyWindow.subviews objectAtIndex:0].mas_right);
make.bottom.mas_equalTo([[UIApplication sharedApplication].keyWindow.subviews objectAtIndex:0].mas_bottom);
}];
}
其中topoint是
//获取绝对高度
UIWindow*window = [[[UIApplicationsharedApplication]delegate]window];
CGRectrect = [weakSelf.segmentViewconvertRect:weakSelf.segmentView.boundstoView:window];
CGPointMake(0, rect.origin.y+rect.size.height) 获取
