循环给字典添加值

循环给字典添加值的时候，每次添加的都是同一个值，找了下原因，发现字典对象每次都是同一个对象，并没有实例化。其实应该在循环里面给它实例化，才能保证每次取的都是不同的对象。

NSMutableArray *timeArray = [NSMutableArray new];

NSMutableDictionary *dictTime = [NSMutableDictionary new];

for (int i = 0; i < transTime.count; i++) {
     
        TransferTransferoutTime *transtime = transTime[i];
        [dictTime setObject:transtime.dictName forKey:@"dictName"];
        [dictTime setObject:transtime.dictValue forKey:@"dictValue"];
        [dictTime setObject:@(transtime.defaultFlag) forKey:@"defaultFlag"];
        
        [timeArray addObject: dictTime];
    }

如下，把字典的实例化放在里面。

NSMutableArray *timeArray = [NSMutableArray new];

for (int i = 0; i < transTime.count; i++) {
       NSMutableDictionary *dictTime = [NSMutableDictionary new];

       TransferTransferoutTime *transtime = transTime[i];
        [dictTime setObject:transtime.dictName forKey:@"dictName"];
        [dictTime setObject:transtime.dictValue forKey:@"dictValue"];
        [dictTime setObject:@(transtime.defaultFlag) forKey:@"defaultFlag"];
        
        [timeArray addObject: dictTime];
    }
