Question

我正在使用iOS应用程序，当我拿到网址时，它会给我以下网址：打印aString的描述：

我的功能是：

- (void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info
{
    [self dismissViewControllerAnimated:YES completion:nil];

for (UIView *v in [_scrollView subviews]) {
    [v removeFromSuperview];
}

CGRect workingFrame = _scrollView.frame;
workingFrame.origin.x = 0;

images = [NSMutableArray arrayWithCapacity：[info count]];

NSLog(@" info count  :%lu",info.count);



countere=(NSUInteger*)info.count;

NSLog(@"  countere  :%lu",(unsigned long)countere);

for (NSDictionary *dict in info) {



  //  NSString *filename;
    image = [dict objectForKey:UIImagePickerControllerOriginalImage];
    [images addObject:image];

    imageview = [[UIImageView alloc] initWithImage:image];
    [imageview setContentMode:UIViewContentModeScaleAspectFit];
    imageview.frame = workingFrame;

 NSURL * imagepath=[info valueForKey:UIImagePickerControllerReferenceURL];
     NSLog(@"fileName : %@",imagepath);
    dropboximagepath=(NSString*)imagepath;

}

我的结果是：

的ImagePath = ＆lt; __ NSArrayI 0x10ad4d490＆gt;（？资产库：//asset/asset.JPG ID = 7E3818C6-EF97-441B-81E4-916DD5B71DD0和放大器; EXT = JPG ）

我想提取

“ assets-library：//asset/asset.JPG？id = 7E3818C6-EF97-441B-81E4-916DD5B71DD0＆amp; ext = JPG ”

从上面的结果。请告诉我如何提取我想要的结果并将其保存在一个字符串中，以便我可以将该url路径发送到下一个控制器？

你收到了一个元素的数组，所以最简单的就是

[array objectAtIndex:0]

它将为您提供NSURL或NSString（取决于逻辑）您可以将NSURL转移到NSString，或者如果您需要提取它的单独部分，您可以使用NSURL方法，例如

– absoluteString
– absoluteURL
– baseURL
– fileSystemRepresentation
– fragment
– host
– lastPathComponent
– parameterString
– password
– path
– pathComponents
– pathExtension
– port
– query
– relativePath
– relativeString
– resourceSpecifier
– scheme
– standardizedURL
– user

如何访问字符串数组中的元素？
