UISearchBar height on iOS8 when showsScopeBar=YES

Question

I\'m using UISearchBar in my app, with showsScopeBar=YES. When running under iOS8 (both in the simulator and on a device) the scope bar is hidden a

Using Janne's answer, I thought it would be helpful to share how to do this automatically with method swizzling.

@implementation UISearchBar (iOS8)

static dispatch_once_t dispatchOnceToken;

+ (void)load {
    if([[[UIDevice currentDevice] systemVersion] floatValue] >= 8)
    {
        dispatch_once(&dispatchOnceToken, ^{
            Class class = [self class];

            SEL originalViewWillAppearSelector = @selector(layoutSubviews);
            SEL swizzledViewWillAppearSelector = @selector(swizzled_layoutSubviews);

            Method originalViewWillAppearMethod = class_getInstanceMethod(class, originalViewWillAppearSelector);
            Method swizzledViewWillAppearMethod = class_getInstanceMethod(class, swizzledViewWillAppearSelector);

            if(class_addMethod(class, originalViewWillAppearSelector, method_getImplementation(swizzledViewWillAppearMethod), method_getTypeEncoding(swizzledViewWillAppearMethod)))
            {
                class_replaceMethod(class, swizzledViewWillAppearSelector, method_getImplementation(originalViewWillAppearMethod), method_getTypeEncoding(originalViewWillAppearMethod));
            }
            else
            {
                method_exchangeImplementations(originalViewWillAppearMethod, swizzledViewWillAppearMethod);
            }
        });
    }
}

- (void)swizzled_layoutSubviews
{
    [self swizzled_layoutSubviews];
    [self sizeToFit];
}

@end

Answer 2

I ran into this problem too. After searching on Apples developer forum I found this thread: https://devforums.apple.com/thread/235803?start=0&tstart=0

And apparently the SearchBar don't automatically does a sizeToFit when it's supposed too. So it's height stays at 44 instead of adjusting to the scope buttons. The bug is not fixed in the iOS8 GM.

I did a simple [self.searchBar sizeToFit] in my viewWillAppear: and that solved it.

Answer 3

This seems to be not an iOS 8 bug but a Xcode 6 GM compiled Storyboard bug as it happens on iOS 6/7 as well.

As suggested it is fixed by calling sizeToFit on the search bar in viewWillAppear.

If you want to do it from a view instead of a controller you can try to place it inside willMoveToWindow.

This bug seems to affect Xcode 5.x builds on iOS 8 and Xcode 6 GM builds on all systems.

Answer 4

This issue is occurring in the iOS 8 release version as well. I added these 2 lines in my viewWillAppear: and that solved it.

- (void)adjustSearchBarToShowScopeBar{ [self.searchBar sizeToFit]; self.tableView.tableHeaderView = self.searchBar; } Just adding [self.searchBar sizeToFit] was covering up my tableview's first row. Just refreshing the tableview header fixed the issue perfectly.
