Question

NSDate *now = [NSDate date];                                 
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];                    
[formatter setDateFormat:@"yyyy"];                     

NSString *stringFromDate = [formatter stringFromDate:now]; 
CGContextShowTextAtPoint(context, 50, 50, stringFromDate, 5);

I am not getting the exact date? also getting warning while compiling
warning: passing argument 4 of ‘CGContextShowTextAtPoint’ from incompatible pointer type

Answer 1

What is the value of stringFromDate? What are you expecting?

also getting warning while compiling

‘CGContextShowTextAtPoint’ from
incompatible pointer type

If you look at the docs for CGContextShowTextAtPoint, you’ll see that the fourth parameter needs to be a char*, not an NSString*.

You have:

GContextShowTextAtPoint(context, 50, 50, stringFromDate, 5);

You want:

GContextShowTextAtPoint(context, 50, 50, [stringFromDate UTF8String], 5);
