一行代码集成多视图滑动点击切换,代码精简美观
有没有想过,如果页签动态减少到三个或者更少,改怎么布局,样式就变化啦
轻轻拖动,松手,tab已切换而页面没切换,这是给使用者留的考题吗?
if (!_tabbarView) {
_tabbarView = ({
HYTabbarView * tabbar = [[HYTabbarView alloc]initWithFrame:CGRectMake(0, 64, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height - 64)];
TestViewController * vc0 = [[TestViewController alloc]init];
vc0.title = @"推荐";
[tabbar addSubItemWithViewController:vc0];
tabbar;
});
}
也就是
-(UIView*)testview{
if (!_testview) {
_testview = ({
UIView *testview = [UIView new];
testview;
});
}
return _testview;
}
这种写法没太明白,为什么这么写? 和
-(UIView*)testview{
if (!_testview) {
_testview = [UIView new];
}
return _testview;
}
写法有什么区别? 第一种的结构为什么是什么样的?它的关键词是什么?
