iOS 删除文件夹下所有文件的方式

删除指定类型的文件。方法如下: 
 
NSString *extension = @"m4r"; 
NSFileManager *fileManager = [NSFileManager defaultManager]; 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
 
NSArray *contents = [fileManager contentsOfDirectoryAtPath:documentsDirectory error:NULL];   
NSEnumerator *e = [contents objectEnumerator]; 
NSString *filename; 
while ((filename = [e nextObject])) { 
 
    if ([[filename pathExtension] isEqualToString:extension]) { 
 
        [fileManager removeItemAtPath:[documentsDirectory stringByAppendingPathComponent:filename] error:NULL]; 
    } 
}
