最近公司要做下部栏，现在总结下技术点，让以后有点记忆；
1：UIStoryboard 的调用
UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
UIViewController *myView = [story instantiateViewControllerWithIdentifier:@"ViewController"];
2：BLock 作为属性
typedefvoid(^MessageUnderMenuViewDelClickBlcok)(void);
@property (nonatomic, copy) MessageUnderMenuViewDelClickBlcok delclickBllock;
if (self.delclickBllock) {
self.delclickBllock();
}
self.underMenu.delclickBllock = ^{
NSLog(@"delclickBllock");
};
3：动画的切换
WeakSelf
__blockBOOLisok =YES;
[self.underMenu.showBtn addBlockForControlEvents:UIControlEventTouchUpInside block:^(__kindof UIControl *sender) {
if(OBJOnceToken(self)) {
self.underMenu.oldFrame = self.underMenu.frame;
}
if(isok) {
[UIView animateWithDuration:0.35 animations:^{
weakSelf.underMenu.y= weakSelf.underMenu.oldFrame.origin.y-(96-36);
self.underMenu.arrowImg.transform = CGAffineTransformMakeRotation(M_PI*2);//旋转
}completion:^(BOOLfinished) {
isok =NO;
}];
}else{
[UIView animateWithDuration:0.35 animations:^{
weakSelf.underMenu.y= weakSelf.underMenu.oldFrame.origin.y;
self.underMenu.arrowImg.transform = CGAffineTransformMakeRotation(M_PI*1);//旋转
}completion:^(BOOLfinished) {
isok =YES;
}];
}
}];
4：把控件加都最上层
[self.view bringSubviewToFront:self.iphoneXBottomView];
5：只调用一次
if (OBJOnceToken(self)) {
self.underMenu.oldFrame = self.underMenu.frame;
}
二：做的过程发现的问题
自定义控件，在使用的时候，使用
setFrame 没用，控件的frame 不对，已不知道是为啥，也许是ios的源代码bug，
只能使用以下的办法
[self.underMenu mas_remakeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(self.view.mas_left).with.offset(0);
make.right.equalTo(self.view.mas_right).with.offset(0);
// make.top.equalTo(self.view.mas_bottom).offset(-36);
make.top.equalTo(self.iphoneXBottomView.mas_top).offset(-36);//==>在x以上的会显示👇安全位置
make.height.mas_equalTo(96);
}];
在刚执行完mas_remakeConstraints:frame 是拿不到的，这个要注意；
