Stop AVPlayer music in another controller
so I have this variable in my delegate named AppDelegate.h:
AVAudioPlayer *introSound;
It plays continuously during first load.
[introSound stop];
What I want to do is stop it fro开发者_JAVA百科m a separate controller, firstController.m.
I tried
[AppDelegate.introSound stop];
but it threw an error saying:
error: expected ':' before '.' token
What is causing this?
I assume you mean a compiler error? AppDelegate refers to the class, not to the instance of the class that is your application delegate. To get that from anywhere, do this:
AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
[appDelegate.introSound stop];
You also need to make sure that introSound is a property, not just an instance variable of AppDelegate.
use this way catch videos/audios in simple and best.do this
NSMutableURLRequest *request1 = [[[NSMutableURLRequest alloc] init] autorelease];
[request1 setHTTPMethod:@"GET"];
NSError *error;
NSURLResponse *response;
NSString *documentFolderPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSFileManager *fileManager1 = [NSFileManager defaultManager];
NSString *videosFolderPath = [documentFolderPath stringByAppendingPathComponent:@"videos"];
//NSString* videosFolderPath = [@"~/Documents/bar.mp3" stringByExpandingTildeInPath];
NSLog(@"video path:%@",videosFolderPath);
//Check if the videos folder already exists, if not, create it!!!
BOOL isDir;
if (([fileManager1 fileExistsAtPath:videosFolderPath isDirectory:&isDir] && isDir) == FALSE) {
//[[NSFileManager defaultManager] createDirectoryAtPath:videosFolderPath attributes:nil];
[fileManager1 createDirectoryAtPath:videosFolderPath withIntermediateDirectories:YES attributes:nil error:nil];
}
