objective-c怎么代码触发按钮点击事件

Answer 1

在控件基类 UIView 上面重实现一组函数

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event;

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;

- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event;

然后根据鼠标点击位置和动作，判断手势，这是比较原始的事件通知了，如果你需要判断高级的手势，比如滑动，多点触控，则可以用系统的手势分析类 来处理。但是事件都是从这里来的。

看你想实现什么效果，最基本的用 pushViewController
MyViewController *myView = [[MyViewController alloc] init];
[self.navigationController pushViewController:myView animated:YES];

或者动画
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.4f]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationTransition:UIViewAnimationOptionTransitionNone forView:myView cache:YES];
[myView setCenter:CGPointMake(512, 384)];

[UIView commitAnimations];
