1、With ARC, you should use strong instead of retain and weak instead of assign when defining the properties.
@interface
Person :
NSObject
@property
(
nonatomic
, strong)
NSString
*firstName;
@property
(
nonatomic
, strong)
NSString
*lastName;
@property
(
nonatomic
, strong)
NSNumber
*yearOfBirth;
@property
(
nonatomic
, strong) Person *spouse;
@end
|
2、ARC forbids 'dealloc','release','autorelease' key words, these words shouldn`t be explicitly invoked!
For instance,[super dealloc] [str release] are not permitted.
3、When you use [[AClass alloc] init], you don`t need to release it.
- (void)takeLastNameFrom:(Person *)person { NSString *oldLastname = [self lastName]; [self setLastName:[person lastName]]; NSLog(@"Lastname changed from %@ to %@", oldLastname, [self lastName]); //oldLastname will stay alive until NSLog is runned }
