Problem with UISearchController

[Zach41]

I imported IQKeyboardManager in my project, and I used UISearchController in my project too, when I clicked cancel button in searchBar, searchBar shifted up weirdly. After I removed IQKeyboardManager, searchBar behaved correctly.

I tried my library with UISearchController and it seems fine. I tested UISearchController with UITableViewController. If you have different configuration then please share demo.

Here is my Controller

static NSString * const ScoreCellIdentifier = @"ScoreCellIdentifier";

@interface ScoreController () <UISearchResultsUpdating, UISearchBarDelegate, UITableViewDelegate, UITableViewDataSource>

@property (nonatomic, strong) UISearchController *searchController;

@end

@implementation ScoreController

- (void)viewDidLoad {
    [super viewDidLoad];

    self.searchController = ({
        SearchResultController *resultController = [[SearchResultController alloc] init];
        UISearchController *searchController = [[UISearchController alloc] initWithSearchResultsController:resultController];
        searchController.dimsBackgroundDuringPresentation = NO;
        self.definesPresentationContext = YES;
        searchController.searchResultsUpdater = self;

        [[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setBackgroundColor:[UIColor colorWithRed:0.918 green:0.933 blue:0.937 alpha:1.000]];
        [[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil] setTitle:@"取消"];

        searchController.searchBar.placeholder = @"如“一年二班 数学 李狗蛋”";
        searchController.searchBar.backgroundImage = [UIImage imageWithColor:[UIColor whiteColor]];

        searchController.searchBar.delegate = self;

        searchController;
    });

    self.tableView.tableHeaderView = _searchController.searchBar;
    self.tableView.allowsSelection = NO;
    self.tableView.dataSource = self;
    self.tableView.delegate = self;
    [self.tableView registerClass:[ScoreControllerCell class] forCellReuseIdentifier:ScoreCellIdentifier];

    self.title = @"成绩";

    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] bk_initWithImage:[UIImage imageNamed:@"naviPlusIcon"]
                                                                                 style:UIBarButtonItemStylePlain handler:^(id sender) {
                                                                                     // TODO: Navi Add Action
                                                                                     DDLogInfo(@"Navigation Add Button In ScoreController");
                                                                                 }];
}

#pragma mark - Table Delegate

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return 5;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    ScoreControllerCell *cell = [tableView dequeueReusableCellWithIdentifier:ScoreCellIdentifier];

    return cell;
}

#pragma mark - Table Delegate

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    return [tableView fd_heightForCellWithIdentifier:ScoreCellIdentifier configuration:^(ScoreControllerCell *cell){

    }];
}

#pragma mark - SearchController Updating

- (void)updateSearchResultsForSearchController:(UISearchController *)searchController {
    NSString *text = searchController.searchBar.text;

    DDLogInfo(@"Search Key: %@", text);

}

#pragma mark - SearchBar delegate

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar {
    [_searchController dismissViewControllerAnimated:NO completion:^{
        searchBar.showsCancelButton = NO;
    }];

}

It's a UIViewController with a TableView as its property.

And this is my search result controller

static NSString * const SearchScoreCellID = @"SearchScoreCell";

@interface SearchResultController ()

@end

@implementation SearchResultController

- (void)viewDidLoad {
    [super viewDidLoad];

    [self.tableView registerClass:[ScoreControllerCell class] forCellReuseIdentifier:SearchScoreCellID];
    self.tableView.allowsSelection = NO;
    self.tableView.tableFooterView = [UIView new];
}

#pragma mark - Table Datasource

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return 5;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    ScoreControllerCell *cell = [tableView dequeueReusableCellWithIdentifier:SearchScoreCellID];
    return cell;
}

#pragma mark - Table Delegate

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    return [tableView fd_heightForCellWithIdentifier:SearchScoreCellID configuration:^(ScoreControllerCell *cell) {

    }];
}

It's just a UITableViewController.

I recorded the result, and there is gif.

There is my Podfile

source "https://git.oschina.net/6david9/Specs.git"

platform :ios, "8.0"

target 'SmartCamp' do
  pod 'SVProgressHUD'
  pod 'AFNetworking'
  pod 'SDWebImage'
  pod 'BlocksKit'
  pod 'YYModel'
  pod 'YYCache'
  pod 'STPopup'
  pod 'MJRefresh'
  pod 'Masonry'
  pod 'YYText'
  pod 'CocoaLumberjack'
  pod 'SDVersion'
  pod 'UITableView+FDTemplateLayoutCell'
  pod 'KMNavigationBarTransition'
  pod 'MXParallaxHeader'
  pod 'KVOController'
  pod 'IQKeyboardManager'
end

When I removed IQKeyboardManager, search bar goes well, I really don't know why. :(

Thanks, I'll check.

[hackiftekhar]

I dont know how the cell will look because it doesn't contain ScoreControllerCell, ScoreControllerCell, fd_heightForCellWithIdentifier, bk_initWithImage. Can you wrap-up all this in a demo?

@Zach41 Do you have any updates?
