使用来自另一个类的值的Objective-c NSArray

Question

I am trying to create a table view in my view based application but I am facing a problem

NSArray *array = [[NSArray alloc] initWithObjects:@"iPod",forecast.desc,nil];
NSLog(@"this is the forecast routeNo = %@", forecast.desc);

As you can see this is the array that shows the values in the table, the result of this code is iPod (only), "forecast.desc" doesn't show anything knowing that forecast is an instance of another class and "desc" is a string in that class

and just to make sure forecast.desc shows the correct information in the log but in the table as if doesn't exist can anyone see where is the problem ?

Thanks

Answer 1

尝试

[[NSArray alloc] initWithObjects:@"iPod", [NSString stringWithFormat:@"%@",forecast.desc], nil];

Answer 2

@bhappy the result of array variable is @"iPod" only means that forecast.desc has nil value.

So try to debug the code using single stepping and check what is the value of desc at the time of initializing the array.

And one more thing if desc is a member variable of class forecast than did you set the property for it, if not then forecast.desc wont work. You should check that first.
