Question

I have a member named _label as an ivar member in class :

@interface CCHelloWorldLayer : CCLayer
{
  CCLabelBMFont *_label;
}

in another codeblock: initializing with this line:

_label = [CCLabelBMFont labelWithString:@"Testing " fntFile:fntName];

question is this:
if I want to modify its text what Should I do ?
I dont see any method like:

[_label setString:@"Well.there is no such a method"];

if I do

_label = [CCLabelBMFont labelWithString:@"Testing " fntFile:fntName];

_label = [CCLabelBMFont labelWithString:@"Well.there is no such a method"
         fntFile:fntName];

is first memory allocation autoreleasing it self ?
is it safe to recall labelWithString method repeately ?
(note:I dont use ARC in test project.and I wont.)

thanks in advice

Answer 1

There is a setString method but it appears to be “private”. The +labelWithString method does create an autorelease object and can be used repeatedly. It looks like it creates a texture, so you would want to create a new texture each time (as opposed to trying to modify it).

In general though, if you want the autoreleased object to stick around, you should retain it and release it when you’re done.
