iOS 8 Today widget alignment issue

问题

Here is my storyboard

I'm using autolayout, and NOT using size classes.

When I ran it on iPhone 5s, it works fine.(both portrait and landscape)

But when I ran it on iPhone 6 plus (portrait), it's not aligning properly.

on iPhone 6 plus (landscape), it's worse.

I know I can use -widgetMarginInsetsForProposedMarginInsets: to set the margin, but in that case I will need to customize the margin for every device. That would be horrible :(

So is there a way to align the subview to the title less painfully?

回答1:

Looks like you have to set it manually. You can do this by creating a constraint, then specifying an IBOutlet to it, and setting the constant depending on the device/orientation.

For reference, here are the margins I found you needed:

5S - 1 (2px)
6 - 1 (2px)
6 plus portrait - 5 (15px)
6 plus landscape - 34 (102px)

You can find which one you need from the size of the extension view, which is 414 pt for a portrait iPhone 6.

Setting the edge insets to zero should fix the problem:

- (UIEdgeInsets)widgetMarginInsetsForProposedMarginInsets:(UIEdgeInsets)defaultMarginInsets
{
    return UIEdgeInsetsZero;
}

回答3:

You need to customise the widget margins:

- (UIEdgeInsets)widgetMarginInsetsForProposedMarginInsets:(UIEdgeInsets)defaultMarginInsets;

Fixes for some devices. Requires Ericas UIDevice-Extension.

- (UIEdgeInsets)widgetMarginInsetsForProposedMarginInsets:(UIEdgeInsets)defaultMarginInsets
{
    defaultMarginInsets.bottom = 0;

    if ([UIDevice.currentDevice.modelIdentifier containsString:@"iPhone7,1"] && self.traitCollection.horizontalSizeClass == UIUserInterfaceSizeClassCompact) {
        defaultMarginInsets.left += 5;
    } else if ([UIDevice.currentDevice.modelIdentifier containsString:@"iPhone7,1"] && self.traitCollection.horizontalSizeClass == UIUserInterfaceSizeClassRegular) {
        defaultMarginInsets.left += 34;
    } else {
        defaultMarginInsets.left += 1;
    }

    return defaultMarginInsets;
}
