Question

When i write the following code, I get the Application tried to push a nil view controller on target error.

BOOL isboyWithGlass;
isboyWithGlass=TRUE;
NSLog(@"%@",isboyWithGlass);

can anyone tell me how to remove this error while i am using the above code.

Answer 1

BOOL while printing it always takes it as int

So print it like

NSLog(@"%d",isboyWithGlass);

It will return as 1 (If it is yes) or 0 (If it is no)

If you want to print it as string then

NSLog(@"%@", (isboyWithGlass ? @"TRUE" : @"FALSE"));
