iphone 利用数组遍历某一文件夹中的图片

1，使用数组遍历某一文件夹中的图片，代码如下：

  NSFileManager *fileManager = [NSFileManager defaultManager];  

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);

    NSString *documentsDirectory = [paths objectAtIndex:0];

NSLog(@"%d",[paths count]);

NSError *error = nil;

NSArray *fileList = [[NSArray alloc] init];

NSMutableArray *filePath = [NSMutableArray arrayWithCapacity:100 ];

NSMutableArray *imgArray = [NSMutableArray arrayWithCapacity:200];

//NSArray *filePath = [[NSArray alloc] init];

fileList = [fileManager contentsOfDirectoryAtPath:documentsDirectory error:&error];

for (NSString *file in fileList) {

NSLog(@"fileName is :%@",file);

[filePath addObject:[documentsDirectory stringByAppendingPathComponent:file]];

}

for (int i = 0; i<[fileList count]; i++) {

UIImage *temp = [UIImage imageWithContentsOfFile:[filePath objectAtIndex:i]];

[imgArray addObject:temp];

} 

[imgView1 setImage:[imgArray objectAtIndex:0]];

[imgView2 setImage:[imgArray objectAtIndex:1]];

[imgView3 setImage:[imgArray objectAtIndex:2]];

[imgView4 setImage:[imgArray objectAtIndex:3]];

[imgView5 setImage:[imgArray objectAtIndex:4]];

[imgView6 setImage:[imgArray objectAtIndex:5]];

[imgView7 setImage:[imgArray objectAtIndex:6]];

[imgView8 setImage:[imgArray objectAtIndex:7]];

[imgView9 setImage:[imgArray objectAtIndex:8]];
