如何从文档目录中获取xml文件的列表

Question

我正在开发一个应用程序。我想从文档目录中获取所有.xml文件的名称，所以请告诉我如何执行此操作。

Answer 1

试试这个：

NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDir = [documentPaths objectAtIndex:0]; 
NSString *xml_path = [documentsDir stringByAppendingPathComponent:@"xmlfolder"]; // if you have folder 
NSArray *list =[NSBundle pathsForResourcesOfType:@"xml" inDirectory:xml_path]; 
NSLog(@"%@",list); 

Answer 2

操作步骤如下：

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *docPath = [paths objectAtIndex:0]; 
NSFileManager *fm = [NSFileManager defaultManager]; 
NSArray *dirContents = [fm contentsOfDirectoryAtPath:docPath error:nil]; 
NSPredicate *fltr = [NSPredicate predicateWithFormat:@"self ENDSWITH '.xml'"]; 
NSArray *xmlFiles = [dirContents filteredArrayUsingPredicate:fltr];
