Question

NSString *one = [NSDictionary dictionaryWithObjectsAndKeys:@"1",@"id",@"Test1",@"text", nil];
    NSString *two = [NSDictionary dictionaryWithObjectsAndKeys:@"2",@"id",@"Test2",@"text", nil];
    NSString *three = [NSDictionary dictionaryWithObjectsAndKeys:@"3",@"id",@"Test3",@"text", nil];

    _options = [NSArray arrayWithObjects:one,two,three,nil];

This is the code i am using and running properly in my code. Now i want it dynamically, like

int total = 20;
    NSMutableArray *arr = [[NSMutableArray alloc] init];
    for(int x = 0; x < total; x++)
    {
        [arr addObject:[NSDictionary dictionaryWithObjectsAndKeys:@"1",@"id",@"Test1",@"text", nil]];
    }

But it’s not working. Can anyone help me out of this.

The main code is like

_options = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:@"1",@"id",@"Test1",@"text", nil],[NSDictionary dictionaryWithObjectsAndKeys:@"1",@"id",@"Test1",@"text", nil],[NSDictionary dictionaryWithObjectsAndKeys:@"1",@"id",@"Test1",@"text", nil],nil];

and i want to create it dynamically ,like the value will go for 1-100. How can i do that

You probably ran into an issue trying to put primitives into the NSDictionary, which isn’t possible. Turn your values into strings.

for(int x = 1; x <= 100; x++) {
    NSString* object1 = [NSString stringWithFormat:@"%d", x];
    NSString* object3 = [NSString stringWithFormat:@"Test%d", x];
    [arr addObject:[NSDictionary dictionaryWithObjectsAndKeys:object1,@"id",object3,@"text", nil]];
}
[_options addObjectsFromArray:arr];
