关于通知的知识网上已有不少介绍，这里就不不做多余的说明了，想提醒的就是
在你发送通知的时候，一定要先有监听者监听才可以，否则将会导致第一次发出的通知无法监听的问题
#import#import "ViewController.h"
@interface Alvin : NSString
@end
@interface Alvin (one)
+ (void)PutOne;
@end
@interface Alvin (two)
+ (void)PutTwo;
@end
#import "Alvin.h"
@implementation Alvin
- (void)dealloc
{
[super dealloc];
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
@end
#import "Alvin.h"
@implementation Alvin (one)
+ (void)PutOne
{
NSLog(@"one");
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(btnone) name:JUMPSUCCESS object:nil];
}
+ (void)btnone
{
NSLog(@"ALvin one");
}
@end
#import "Alvin.h"
@implementation Alvin (two)
+ (void)PutTwo
{
NSLog(@"two");
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(btntwo) name:JUMPSUCCESS object:nil];
}
+ (void)btntwo
{
NSLog(@"ALvin two");
}
@end
