小编Aar*_*Oza的帖子

我想在ios 8的警报视图中添加文本输入.我知道它已经完成,UIAlertController但没有任何想法.怎么做 ？

我做了什么: -

我已经添加了在单元格完全可见时播放视频的代码,当我向下或向上滚动时,它会再次重新加载tableview并再次播放视频.但是,我的要求是不同的.

我真正想要的是:

我想播放视频,直到完全可见的向后或向前的单元格.当用户向下滚动或向上滚动时,它不会影响直到完全可见的向后或向前单元格.

设计

Table Cell Layout Description
-> Video Table Cell (Fix height 393) 
    -> Content View
    -> Main view - (as per Content view of Table view Cell)
        -> Title View (0, 0, MainView.width, 57)
        -> Video View (0, 57, MainView.width, 200);
        -> Description View (0, 257, MainView.width, 136) 

编码:

VideoTableCell.h

#import <UIKit/UIKit.h>

#import <AVFoundation/AVFoundation.h>



@interface VideoTableCell : UITableViewCell

@property (strong, nonatomic) IBOutlet UIView *viewForVideo;

@property (strong, nonatomic) IBOutlet UIImageView *imgThumb;

@property (strong, nonatomic) IBOutlet UIButton …

我在演示应用程序中实现了Facebook App邀请.它工作正常,但没有收到通知.

我在我的问题中添加了所有细节,现在任何人都可以告诉我代码中的问题是什么,我该怎么做才能解决这个问题.我已经创建了测试用户来测试这个应用程序.

此代码工作正常,它启动一个对话框,显示朋友列表,并显示应用程序邀请已发送,但当我在朋友帐户中检查它时,它不显示任何通知.

我的Info.plist文件

我认为我在URL类型(URL Schemes)下的info.plsit中有错误.我写了一个动作,这是该方法的名称,但我不知道我应该在本专栏中写些什么.

Appdelegate.m

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url   sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    BFURL *parsedUrl = [BFURL URLWithInboundURL:url sourceApplication:sourceApplication];
    if ([parsedUrl appLinkData])
    {
        NSURL *targetUrl = [parsedUrl targetURL];
        [[[UIAlertView alloc] initWithTitle:@"Received link:"
                                    message:[targetUrl absoluteString]
                                   delegate:nil
                          cancelButtonTitle:@"OK"
                          otherButtonTitles:nil] show];
    }
        return YES; }

ViewController.h

appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didCompleteWithResults:(NSDictionary *)results调用时获得结果为null

- (IBAction)action:(UIButton *)sender
{

    FBSDKAppInviteContent *content =[[FBSDKAppInviteContent alloc] init];
    content.appLinkURL = [NSURL URLWithString:@"https://fb.me/*****************"];

    [FBSDKAppInviteDialog showFromViewController:self withContent:content delegate:self];
}

 - (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didCompleteWithResults:(NSDictionary *)results
{
    NSLog(@" result %@",results);
} …

当前视图控制器不使用ios 9,当我按下按钮时它没有重定向到当前视图控制器.

为什么会这样？

我试过下面的代码

 RegistrationViewController * viewController =[[UIStoryboard storyboardWithName:@"Registration" bundle:nil] instantiateViewControllerWithIdentifier:@"RegistrationViewController"];
 [self presentViewController:viewController animated:YES completion:nil];

我也试过下面的代码

 UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Registration"
                                                         bundle:nil];
 RegistrationViewController *add =
 [storyboard instantiateViewControllerWithIdentifier:@"RegistrationViewController"];
 [self presentViewController:add animated:YES completion:^{
        dispatch_async(dispatch_get_main_queue(), ^{
            [self presentViewController:add
                               animated:YES
                             completion:nil];
        });
  }];

编辑

我的完整代码在这里.我正在使用Xcode 7并使用ios 9运行它

#import "LoginViewController.h"
#import "RegistrationViewController.h"

@interface LoginViewController ()

@end

@implementation LoginViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];

我试图从我的iOS应用程序发送短信应用程序的短信,但它没有成功.我在下面添加了我的代码,请告诉我我做错了什么.我的设备安装了什么应用,但我仍然无法发送任何短信.

- (IBAction)whatAppInvite:(id)sender
    {
        NSString * strTextPost = [@"" stringByAppendingFormat:@"Hey try this app. Its amazing. \n\n https://itunes.apple.com/us/app/google-search/*********2?mt=8"];

        strTextPost = [strTextPost stringByReplacingOccurrencesOfString:@"/" withString:@"%2F"];
        strTextPost = [strTextPost stringByReplacingOccurrencesOfString:@"?" withString:@"%3F"];
        strTextPost = [strTextPost stringByReplacingOccurrencesOfString:@"," withString:@"%2C"];
        strTextPost = [strTextPost stringByReplacingOccurrencesOfString:@"=" withString:@"%3D"];
        strTextPost = [strTextPost stringByReplacingOccurrencesOfString:@"&" withString:@"%26"];
        strTextPost = [strTextPost stringByReplacingOccurrencesOfString:@"." withString:@"%2E"];
        strTextPost = [strTextPost stringByReplacingOccurrencesOfString:@"'" withString:@"%27"];
