我有一个iOS应用程序,只有一个播放器和登录功能。它应该按照以下方式工作:
- 1)运行应用程序
- 2)登录
- 3)登录后视频直接开始播放
- 4)如果您退出视频,则应询问是否要注销
- 5)如果选择“否”,则应继续播放流
- 6)如果选择“是”,则注销应用程序
- 7)如果用户在不关闭应用程序的情况下再次登录,则应从步骤2-7重复。
Warning: <AVPlayerViewController: 0x7f9fca08aa00> is trying to exit full screen, but is not in its view's window's view controller hierarchy. This results in undefined behavior.
我对xcode ios和Objective-C非常陌生,以下是我的代码:
- (void)viewDidLoad {
NSLog(@"ChannelListingViewController::viewDidLoad(): Called...");
[super viewDidLoad];
self.check=1;
NSLog(@"ChannelListingViewController::viewDidLoad(): Exiting...");
}
-(void) playVideo
{
self.channelURL = [TulixAppGlobalConfig getUserSubscribedPlanChannels];
NSURL *url = [[NSURL alloc] initWithString:[self.channelURL[1] getChannelHlsStreamURL]];
self.player = [AVPlayer playerWithURL:url];
// create a player view controller
[self presentViewController:controller animated:YES completion:nil];
self.controller.player = self.player;
[self.player play];
}
-(void) viewDidAppear:(BOOL)animated
{
self.controller = [[AVPlayerViewController alloc] init];
NSLog(@"ChannelListingViewController::viewDidAppear(): Called...");
if(self.check==0)
{
NSLog(@" 0 checkvalue: %i",check);
[self showLogoutConfirmationDialog];
}
else{
self.check =0;
NSLog(@" 1 checkvalue: %i",check);
[self playVideo];
}
[self spawnKeepAliveThread];
NSLog(@"ChannelListingViewController::viewDidAppear(): Exiting...");
}
-(void) showLogoutConfirmationDialog
{
void (^ptrFuncCompletionBlock)(void) = ^(void) { NSLog(@"ChannelListingViewController::showLogoutConfirmationDialog():GENERIC CALL BACK...");
[self attemptToLogoutUser];
};
NSLog(@"ChannelListingViewController::showLogoutConfirmationDialog(): Called...");
UIAlertAction* alertActionYes = [UIAlertAction actionWithTitle:@"Yes" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
//Do Some action here
NSLog(@"ChannelListingViewController::showLogoutConfirmationDialog:: Called for YES...");
self.check = 1;
NSLog(@" yes checkvalue: %i",check);
[self.activeAlterController dismissViewControllerAnimated:NO completion:ptrFuncCompletionBlock];
[self attemptToLogoutUser];
}];
UIAlertAction* alertActionNo = [UIAlertAction actionWithTitle:@"No" style:UIAlertActionStyleCancel
handler:^(UIAlertAction * action) {
NSLog(@"ChannelListingViewController::showLogoutConfirmationDialog:: Called for NO...");
[self playVideo];
}];
NSMutableArray* arrayAlertActions = [NSMutableArray arrayWithObjects:alertActionYes, alertActionNo, nil];
self.activeAlterController = [HelperUtility showMultiButtonDialogHavingTitle:@"Logout" withMessage:@"Are you sure you want to log out?" andAlertActions:arrayAlertActions];
[self presentViewController:self.activeAlterController animated:YES completion:nil];
NSLog(@"ChannelListingViewController::showLogoutConfirmationDialog(): Exit ");
我真的不明白为什么在注销后它不起作用,需要帮助。
