如何通过xcode搜索iphone中的所有声音文件

Question

我是xcode编程的新手。我需要的是搜索所有声音文件并在表格视图中显示它们。任何一个请给我一个想法

Answer 1

You can get all sound files by simply checking the extension of file. Below I have given the example for mp3 files. If you want to also search for another extension then simply add one more extension in the " OR " condition:

1. Find the resourcePath ie directory, because all sound files are resources
2. Get the list of all files in that directory

3. Now search for a specific extension in that list

    NSString *bundlePath = [[NSBundle mainBundle] resourcePath]; NSFileManager *filemgr = [[NSFileManager alloc] init]; NSArray *allFiles = [filemgr contentsOfDirectoryAtPath:bundlePath error:NULL]; for (NSString *fileName in allFiles) { if ([[fileName pathExtension] isEqualToString:@"mp3"]) { NSString *fullFilePath = [bundlePath stringByAppendingPathComponent:fileName]; //do whatever you want to do with the path } }

If you are looking for Sound files within your app, Ravindra has already answered it.

If you are looking for Sound files from all other Music Apps in the iPhone, I doubt if you can access them.

You can however access the Songs from the users iTunes Music Library. You will need to use the MPMediaPickerController .
