我在您的逻辑中找不到任何问题.但是，为什么不以不同的方式尝试它呢?可以使用[UIApplication sharedApplication] .delgate将项目的值委托给那里的数组，然后从第二个选项卡从那里访问它.因为您将从两个选项卡访问同一对象，所以加载不会有任何问题.

I cant find any problem in your logic. But why dont you try it in a diffent way. Projects application delegate could be accessed using [UIApplication sharedApplication].delgate set Values to an array there and access it from there from the second tab . since you would be accessing same object from two Tabs there wont be any problem in loading.
