大佬教程收集整理的这篇文章主要介绍了ios – 从NSMutableDictionary中删除所有数据，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
NSMutableDictionary *lDict = [[NSMutableDictionary alloc]init]; [lDict setObject:lDate forKey:@"date"]; [lDict setObject:presentationId forKey:@"pptId"]; [lDict setObject:presentationName forKey:@"PresentationName"]; [lDict setObject:presentationDesc forKey:@"PresentationDesc"]; [lDict setObject:presentationThumb forKey:@"presentationThumb"]; [lDict setObject:postCallRowId forKey:@"postCallId"]; [lDict setObject:userReaction forKey:@"userReaction"]; [lDict setObject:appDel.gRegion forKey:@"Region"]; [lDict setObject:@"Presentation" forKey:@"ContentType"]; [durationArray addObject:lDict]; //here I am having data in array [lDict removeAllObjects]; lDict=nil; //here I lost data in array also
NSMutableDictionary *lDict = [[NSMutableDictionary alloc]init]; [lDict setObject:lDate forKey:@"date"]; [lDict setObject:presentationId forKey:@"pptId"]; [lDict setObject:presentationName forKey:@"PresentationName"]; [lDict setObject:presentationDesc forKey:@"PresentationDesc"]; [lDict setObject:presentationThumb forKey:@"presentationThumb"]; [lDict setObject:postCallRowId forKey:@"postCallId"]; [lDict setObject:userReaction forKey:@"userReaction"]; [lDict setObject:appDel.gRegion forKey:@"Region"]; [lDict setObject:@"Presentation" forKey:@"ContentType"]; //make a new dictionary and save it [durationArray addObject:[[NSDictionary alloc] initWithDictionary:lDict]]; [lDict removeAllObjects]; lDict=nil;
在从可变字典中删除所有对象之前,请创建具有相同内容的新字典并将其保存到数组中.
通过创建新词典,您仍然可以在原始词典中维护键/值对设置,而不仅仅是保存值.
以上是大佬教程为你收集整理的ios – 从NSMutableDictionary中删除所有数据全部内容，希望文章能够帮你解决ios – 从NSMutableDictionary中删除所有数据所遇到的程序开发问题。
