Question about how objective c property setters work

Are 开发者_如何学JAVAmy two assumptions about properties correct?

@interface Foo : NSObject {
NSDate *Created;
}

@property (nonatomic, retain) NSDate *Created;

@end

@implementation Foo

@synthesize Created;

- (id) init {
if(self = [super init])
{
    Created = [NSDate date]; //this will not call the setter and instead just access the variable directly, which means it will not automatically get retained for me.
    self.Created = [NSDate date]; // this will call the setter, which will retain the variable automatically for me.
}
return self;
}

- (void)dealloc {
    [Created release]   
    [super dealloc];
}
@end

Yes; that is correct.

Note that the instance variable should be created; it should start with a lowercase letter. I'd also recommend creationDate.

It is recommended not to use properties in dealloc or init, so in the init method instead of doing self.propertyName = [NSDate date]; you should do fieldName = [[NSDate alloc] init]; the release in dealloc is fine though
