How to set tag of UIbutton with 2 dimensional array

I want to set tag of UIbutton with 2 dimensional arra开发者_Python百科y ->

Here my code, don't know where I am wrong.

for(int i = 0 ; i<[arrWeekly_Fetch_DataForLandscapeMode count] ; i++)
{           
    btnLandscape_Button = [UIButton buttonWithType:UIButtonTypeCustom];
    btnLandscape_Button.backgroundColor = [UIColor clearColor];
    btnLandscape_Button.frame = CGRectMake(0,0,200,50);
    [btnLandscape_Button.titleLabel setFont:[UIFont systemFontOfSize:14]];
    btnLandscape_Button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
    [arrCommonDays[1][i] addObject:[arrWeekly_Fetch_DataForLandscapeMode objectAtIndex:i]];
    [btnLandscape_Button setTag:[1][arrWeekly_Fetch_DataForLandscapeMode objectAtIndex:i]];
    [btnLandscape_Button addTarget:self    action:@selector(btnClick_ForDetailInformation_For_Class_InLandscapeMode:) forControlEvents: UIControlEventTouchUpInside];
            [btnLandscape_Button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
            [viewForDisplayData_OnDaily addSubview:btnLandscape_Button];

            [btnLandscape_Button setTitle:[dictWeeklyData_InLandscape_Mode objectForKey:@"sSubjectCode"] forState:UIControlStateNormal];
        }

If I understood correctly that your arrWeekly_Fetch_DataForLandscapeMode array is a 2 dimensional one (array of arrays) then you should extract values from it the next way:

[btnLandscape_Button setTag:[[arrWeekly_Fetch_DataForLandscapeMode objectAtIndex:i] objectAtIndex:1]];

or

[btnLandscape_Button setTag:[[arrWeekly_Fetch_DataForLandscapeMode objectAtIndex:1] objectAtIndex:i]];

as for your needs.
