InAppSettingsKit 标签栏，不调用 settingsViewController

Question

对于 Iphone 应用，我尝试实现 InAppSettingsKit（标签栏版本）。我成功地将库示例集成到我的应用程序中，但没有调用“settingsViewController”方法。 这是我的代码：

.h

#import "InAppSettingsKit/IASKAppSettingsViewController.h"

@interface Settings : IASKAppSettingsViewController

@end

.m

#import "Settings.h"
#import <MessageUI/MessageUI.h>
#import "InAppSettingsKit/IASKSpecifier.h"
#import "InAppSettingsKit/IASKSettingsReader.h"
#import "CustomViewCell.h"

@interface Settings ()
- (void)settingDidChange:(NSNotification*)notification;

@end

@implementation Settings

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(settingDidChange:) name:kIASKAppSettingChanged object:nil];
    BOOL enabled = [[NSUserDefaults standardUserDefaults] boolForKey:@"AutoConnect"];
    self.hiddenKeys = enabled ? nil : [NSSet setWithObjects:@"AutoConnectLogin", @"AutoConnectPassword", nil];
    self.tableView = [[UITableView alloc] initWithFrame:self.view.frame style:UITableViewStyleGrouped];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark -
#pragma mark IASKAppSettingsViewControllerDelegate protocol
- (void)settingsViewControllerDidEnd:(IASKAppSettingsViewController*)sender {
    [self dismissModalViewControllerAnimated:YES];

    // your code here to reconfigure the app for changed settings
}

// optional delegate method for handling mail sending result
- (void)settingsViewController:(id<IASKViewController>)settingsViewController mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {

    if ( error != nil ) {
        // handle error here
    }

    if ( result == MFMailComposeResultSent ) {
        // your code here to handle this result
    }
    else if ( result == MFMailComposeResultCancelled ) {
        // ...
    }
    else if ( result == MFMailComposeResultSaved ) {
        // ...
    }
    else if ( result == MFMailComposeResultFailed ) {
        // ...
    }
}

        heightForHeaderForSection:(NSInteger)section {
    NSString* key = [settingsViewController.settingsReader keyForSection:section];
    if ([key isEqualToString:@"IASKLogo"]) {
        return [UIImage imageNamed:@"imager.png"].size.height + 25;
    } else if ([key isEqualToString:@"IASKCustomHeaderStyle"]) {
        return 55.f;
    }
    return 0;
}

- (UIView *)settingsViewController:(id<IASKViewController>)settingsViewController
                         tableView:(UITableView *)tableView
           viewForHeaderForSection:(NSInteger)section {
    NSString* key = [settingsViewController.settingsReader keyForSection:section];
    if ([key isEqualToString:@"IASKLogo"]) {
        UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"iconr.png"]];

        //figure out the title from settingsbundle
        label.text = [settingsViewController.settingsReader titleForSection:section];

        return label;

您是否设置了IASKSettingsDelegate 委托？

有点像

self.settingsviewController.delegate = self;

在您的viewDidLoad 中。当然，您需要在您的 XIB 或 Storyboard 中连接的 settingsViewController 的 IBOutlet 属性。
