stringWithContentsofurl生成泄漏

Question

我试图通过

获取数据

  

NSString * string = [NSString   stringWithContentsOfURL：[NSURL   URLWithString：url]];

一切正常，但是当我使用性能工具运行它时，它会发现此行的泄漏。

这是我使用的整个方法：

- (NSMutableDictionary *) getOutputImagesData: (URLParserImagesData) data
{
    NSString *type = (data == URLParserImagesDataLatestImage) ? @"img" : @"size";

    NSString *url = [NSString stringWithFormat: @"%s%s%s", [URLParserSiteURLforCategories UTF8String], [URLParserType UTF8String], [type UTF8String]];

    //i get leaks here      
    NSString *string = [NSString stringWithContentsOfURL: [NSURL URLWithString: url]];
    NSArray *imagesTemp = [string componentsSeparatedByString: @","];
    NSMutableDictionary *outputImages = [NSMutableDictionary dictionary];
    for(NSString *img in imagesTemp)
    {
    NSArray *splitStrings = [img componentsSeparatedByString: @"="];

    if(data == URLParserImagesDataImagesCount)
    {
        NSNumber *integerValue = [NSNumber numberWithInt: [[splitStrings objectAtIndex:1] intValue]];
        [outputImages setObject: integerValue forKey: [splitStrings objectAtIndex:0]];
    }
    else
        [outputImages setObject: [splitStrings objectAtIndex:1] forKey: [splitStrings objectAtIndex:0]];
    }

    return outputImages;
}

Answer 1

您的代码没有任何问题。

Answer 2

stringWithContentsOfURL:是deprecated。请尝试使用stringWithContentsOfURL:encoding:error:或stringWithContentsOfURL:usedEncoding:error:。
