Question

使用JSQMessagesViewController获取导航栏的问题，我尝试在我的项目中获取导航栏，但未能得到它。请告诉我需要添加哪些方法才能获得它。

#import "JSQMessagesCollectionViewFlowLayout.h"
#import "JSQMessages.h"

@interface ChatpageViewController : JSQMessagesViewController
{
NSMutableArray * fularray;
}
@property(nonatomic,strong)NSDictionary * receivedict;

@property (strong, nonatomic) IBOutlet UILabel *name;
@property (strong, nonatomic) IBOutlet UILabel *mobile;

@property (strong, nonatomic) JSQMessagesBubbleImage *outgoingBubbleImageData;
@property (strong, nonatomic) JSQMessagesBubbleImage *incomingBubbleImageData;

@end

#import "ChatpageViewController.h"
@interface ChatpageViewController ()
@end
@implementation ChatpageViewController
@synthesize receivedict,name,mobile;

//-(void)viewWillAppear:(BOOL)animated
//{
//

// // self.collectionView.collectionViewLayout.springinessEnabled = YES;
//}

    (void)viewDidLoad
    {
    [super viewDidLoad];

    fularray = [[NSMutableArray alloc] init];
    // Do any additional setup after loading the view.
    // [self.navigationController setNavigationBarHidden:NO animated:YES];
    NSLog(@"%@",receivedict);
    name.text = [receivedict objectForKey:@"Name"];
    mobile.text =[receivedict objectForKey:@"Mobile"];

    JSQMessagesBubbleImageFactory *bubbleFactory = [[JSQMessagesBubbleImageFactory alloc] init];

    self.outgoingBubbleImageData = [bubbleFactory outgoingMessagesBubbleImageWithColor:[UIColor jsq_messageBubbleBlueColor]];
    self.incomingBubbleImageData = [bubbleFactory incomingMessagesBubbleImageWithColor:[UIColor jsq_messageBubbleLightGrayColor]];

    }

    (id)collectionView:(JSQMessagesCollectionView *)collectionView messageBubbleImageDataForItemAtIndexPath:(NSIndexPath *)indexPath
    {
    JSQMessage *message = [fularray objectAtIndex:indexPath.item];

    if ([message.senderId isEqualToString:self.senderId]) {
    return self.outgoingBubbleImageData;
    }

    return self.incomingBubbleImageData;
    }

    (id)collectionView:(JSQMessagesCollectionView *)collectionView avatarImageDataForItemAtIndexPath:(NSIndexPath *)indexPath {
    return [JSQMessagesAvatarImageFactory avatarImageWithUserInitials:@"JL" backgroundColor:[UIColor blueColor] textColor:[UIColor whiteColor] font:[UIFont systemFontOfSize:12.0] diameter:30.0];
    }

    (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return [fularray count];
    }

    (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return 1;
    }

    (id)collectionView:(JSQMessagesCollectionView *)collectionView messageDataForItemAtIndexPath:(NSIndexPath *)indexPath {
    return fularray[indexPath.row];
    }

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

    (NSString *)senderId
    {
    return [receivedict objectForKey:@"Mobile"];
    }

    (NSString *)senderDisplayName
    {

    return [receivedict objectForKey:@"Name"];
    }

    (NSDate *)date
    {
    return 18/03/2016;
    }

    (void)didPressSendButton:(UIButton *)button withMessageText:(NSString *)text senderId:(NSString *)senderId senderDisplayName:(NSString *)senderDisplayName date:(NSDate *)date
    {

    [JSQSystemSoundPlayer jsq_playMessageSentSound];

    JSQMessage *message = [[JSQMessage alloc] initWithSenderId:senderId
    senderDisplayName:senderDisplayName
    date:date
    text:text];

    [fularray addObject:message];
    [self.collectionView reloadData];
    [self finishSendingMessageAnimated:YES];
    NSLog(@"%@",message);
    }

Answer 1

转到MainStoryboard-＆gt;选择您的Controller-＆gt;在菜单中选择Editor-＆gt;嵌入 - ＆gt;导航控制器

Answer 2

中的JSQMessagesViewController.m文件更改 - （void）jsq_updateCollectionViewInsets

[self jsq_setCollectionViewInsetsTopValue：self.topContentAdditionalInset + 64 bottomValue：CGRectGetMaxY（self.collectionView.frame） - CGRectGetMinY（self.inputToolbar.frame）];

我无法使用JSQMessagesViewController获取导航栏
