viewController的生命周期
代码写下A、B控制器的打印事件
A的打印事件
- (void)viewDidLoad {
[super viewDidLoad];
NSLog(@"viewDidLoad");
}
+ (void)initialize{
[super initialize];
NSLog(@"initialize");
}
- (instancetype)init{
self= [superinit];
if(self) {
NSLog(@"init");
}
return self;
}
- (void)loadView{
[super loadView];
NSLog(@"loadView");
}
- (void)viewWillAppear:(BOOL)animated{
[superviewWillAppear:animated];
NSLog(@"viewWillAppear");
}
- (void)viewWillLayoutSubviews{
[super viewWillLayoutSubviews];
NSLog(@"viewWillLayoutSubviews");
}
- (void)viewDidLayoutSubviews{
[super viewDidLayoutSubviews];
NSLog(@"viewDidLayoutSubviews");
}
- (void)viewDidAppear:(BOOL)animated{
[superviewDidAppear:animated];
NSLog(@"viewDidAppear");
}
-(void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
NSLog(@"viewWillDisappear");
}
- (void)viewDidDisappear:(BOOL)animated{
[superviewDidDisappear:animated];
NSLog(@"viewDidDisappear");
}
- (void)dealloc{
NSLog(@"dealloc");
}
B的打印事件
- (void)viewDidLoad {
[super viewDidLoad];
NSLog(@"viewDidLoad1");
}
+ (void)initialize{
[super initialize];
NSLog(@"initialize1");
}
- (instancetype)init{
self= [superinit];
if(self) {
NSLog(@"init1");
}
return self;
}
- (void)loadView{
[super loadView];
NSLog(@"loadView1");
}
- (void)viewWillAppear:(BOOL)animated{
[superviewWillAppear:animated];
NSLog(@"viewWillAppear1");
}
- (void)viewWillLayoutSubviews{
[super viewWillLayoutSubviews];
NSLog(@"viewWillLayoutSubviews1");
}
- (void)viewDidLayoutSubviews{
[super viewDidLayoutSubviews];
NSLog(@"viewDidLayoutSubviews1");
}
- (void)viewDidAppear:(BOOL)animated{
[superviewDidAppear:animated];
NSLog(@"viewDidAppear1");
}
-(void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
NSLog(@"viewWillDisappear1");
}
- (void)viewDidDisappear:(BOOL)animated{
[superviewDidDisappear:animated];
NSLog(@"viewDidDisappear1");
}
- (void)dealloc{
NSLog(@"dealloc1");
}
