根据类型设置本地对象，如果它不是nil，则使用它：

for (id uiComponent in uiviews) {
    UIView *uiView;
    UIImageView *uiImageView;

    if ([AQSViewHelper isEntryOfTypeUIView:uiComponent]) {
        uiView = (UIView *)uiComponent;
    }
    if ([AQSViewHelper isEntryOfTypeUIImageView:uiComponent]) {
        uiImageView = (UIImageView *)uiComponent;
    }

    if (uiView) {
        // do what you want because it's a UIView
        if ([uiView isHidden]) {
            // ...
        }
        // etc ...
    }
    if (uiImageView) {
        // do what you want because it's a UIView
        if ([uiImageView isHidden]) {
            // ...
        }
        // etc ...
    }
}

或者，由于您已经处于if块中，因此可以在此处进行：

for (id uiComponent in uiviews) {
    if ([AQSViewHelper isEntryOfTypeUIView:uiComponent]) {
        // do what you want because it's a UIView
        UIView *uiView = (UIView *)uiComponent;
        if ([uiView isHidden]) {
            // ...
        }
        // etc ...
    }
    if ([AQSViewHelper isEntryOfTypeUIImageView:uiComponent]) {
        // do what you want because it's a UIImageView
        UIImageView *uiImageView = (UIImageView *)uiComponent;
        if ([uiImageView isHidden]) {
            // ...
        }
        // etc ...
    }
}
