提取扩展名并保存图像名称

Question

我有几个图像在“ProjectImages”文件夹中，并希望从上述文件夹中检索图像文件名并将其存储在数组中，然后我想提取这些图像的扩展名文件并将其存储在另一个阵列中。我能够从文件夹中检索图像文件名并提取扩展名，但我不知道如何将提取的文件名存储在另一个数组中。下面是代码

//get image name from the folder 
    NSError *error; 
    NSFileManager *fileMgr = [NSFileManager defaultManager]; 
    NSString *directory = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"ProjectImages"]; 

    NSArray *files=[fileMgr contentsOfDirectoryAtPath:directory error:&error]; 

//extract the extension 
NSString *imageNames=nil; 
    for (NSString *name in files) { 
     if (!imageNames) imageNames = [[name lastPathComponent] stringByDeletingPathExtension]; 
     else imageNames = [imageNames stringByAppendingFormat:@" %@",[[name lastPathComponent] stringByDeletingPathExtension]]; 

    } 
NSLog(@"%@",imageNames); --> This returns one single name with all the image name, which i don't want, instead i want to store each extracted file name in array and wanted to compare the string entered by the user with this array. how to do it ?

You are not storing image name in array 
Try this way 


    //get image name from the folder 
    NSError *error; 
    NSFileManager *fileMgr = [NSFileManager defaultManager]; 
    NSString *directory = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"ProjectImages"]; 
    NSArray *files=[fileMgr contentsOfDirectoryAtPath:directory error:&error]; 
    //extract the extension 
    NSMutableArray *array = [[NSMutableArray alloc]init]; 
    for (NSString *name in files) { 
     NSString imageName = [[name lastPathComponent] stringByDeletingPathExtension]; 
if ([array indexOfObject:imageName inRange:NSMakeRang(0,[array count])]!=NSNotFound){ 
//duplicate 
} 
else 
{ 
[array addObject:imageName]; 
} 

} 
    NSLog(@"%@",array);
