一.系統(tǒng)方法.
view加載完畢
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(@"WKOneViewController-viewDidLoad");
}
view即將顯示到window上
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
NSLog(@"WKOneViewController-viewWillAppear");
}
view顯示完畢(已經(jīng)顯示到窗口)
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
NSLog(@"WKOneViewController-viewDidAppear");
}
view即將從window上移除(即將看不見)
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
NSLog(@"WKOneViewController-viewWillDisappear");
}

- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
NSLog(@"WKOneViewController-viewDidDisappear");
}
view即將銷毀的時(shí)候調(diào)用
- (void)viewWillUnload
{
[super viewWillUnload];
}
view銷毀完畢的時(shí)候調(diào)用
