ios – Xcode 8与“发布：最快,最小[-Os]”有一些奇怪的问题,在

调试生产&发布

当我使用调试或生产配置运行我的应用程序,它的工作正常没有任何问题,但是当我更改我的构建配置以释放它给我一些奇怪的问题,如一些字符串值不存储在plist文件中,当我调试我的发布模式,我在调试器中没有任何价值.

对我的代码和构建设置进行了太多的调查,并提出了一些建议形式,所以我已经做了如下改变了我的Build设置.

在Apple LLVM 8.0代码生成标头下更改优化级别

获取以下问题优化级别：

下列问题解决了优化级别的变化：

不知道为什么它在无[-O0]中工作.

任何人都可以帮助我上面的补丁？

以上是影响优化级别的敏感部分.

我保存的书签代码,我有价值,但仍然存储在plist的NULL.

    DimensionModel *aDimensionModel = APPDELEGATE.selected_dimensionModel;
    EmirateModel *aEmirateModel = APPDELEGATE.selected_emirateModel;

    __weak NSString *aStrTitle = [NSString stringWithFormat:@"%@",aDimensionModel.dimension_description];
    aStrTitle = [aStrTitle stringByReplacingOccurrencesOfString:@"(null)" withString:@""];

    if (IS_ENGLISH) {
        aStrTitle = [aStrTitle stringByAppendingString:[NSString stringWithFormat:@" - %@ - %@ - %@",aDivisionModel.division_name,aEmirateModel.emirate_name,[self.bookMarkViewModel.strDataType isEqualToString:@"Number"]?@"(0)":@"(%)"]];
    }else{
        aStrTitle = [aStrTitle stringByAppendingString:[NSString stringWithFormat:@" - %@ - %@ - %@",[Utilities getEmirateNameinArabicByCode:aEmirateModel.emirate_code],[self.bookMarkViewModel.strDataType isEqualToString:@"Number"]?@"(0)":@"(%)"]];

    NSMutableDictionary *aMutDicGraphDetail = [NSMutableDictionary new];

    [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",self.bookMarkViewModel.strSelectedDim] forKey:@"DimCode"];
    [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",aStrVCName] forKey:@"VCName"];
    [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",PLIST_TITLE_BOOKMARK] forKey:@"PlistBookmark"];
    [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",IS_ENGLISH?@"ENGLISH":@"ARABIC"] forKey:@"Language"];

        [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",[LanguageUtility getLocalizedStringForKey:aStrVCName]] forKey:@"Title"];
    }else{
        [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",aStrTitle] forKey:@"Title"];
    }


    [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",APPDELEGATE.selectedDimRecordTimeModel.record_time] forKey:@"RecordTime"];
    [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%ld",(long)APPDELEGATE.selectedDimRecordTimeModel.record_year] forKey:@"RecordYear"];

    [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",self.bookMarkViewModel.strDataType] forKey:@"DataType"];

    [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%d",APPDELEGATE.isDataTypeSwitchHide] forKey:@"switchHide"];

    /* Check for RegionVC  and CountryVC*/
    if ([aStrVCName isEqualToString:@"RegionMainVC"] || [aStrVCName isEqualToString:@"CountryMainVC"]){
        [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%@",self.bookMarkViewModel.strComparison] forKey:@"Comparison"];
        [aMutDicGraphDetail setObject:[NSString stringWithFormat:@"%ld",self.bookMarkViewModel.intSelectedRegionId] forKey:@"RegionId"];
    }
    [self.bookMarkViewModel saveBookmark:aMutDicGraphDetail];

    aStrVCName = nil;
}

使用上面的代码,所有的值都被成功地存储到plist中,但是aStrTitle在它里面是有价值的,它仍然存储为null.
