Question

I get the error (Lvalue required as left operand of assignment) for this code:

[[addAlertViewController alertsArray] = [NSMutableArray arrayWithObjects:nil] retain];

How can I fix it?

Answer 1

The appropriate Code is as follows:

[addAlertViewController setAlertsArray:[NSMutableArray arrayWithObjects:nil]];

Be careful that you have declared in your @interface of addAlertViewController‘s Class:

@property (nonatomic, retain) NSMutableArray *alertsArray;

And in your implementation file

@synthesize alertsArray;

And.. I’ll agree with @taskinoor, RTFM.
