ios代码备忘
1.自定义导航栏返回按钮
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"back" style:UIBarButtonItemStyleBordered target:self action:@selector(back)];
2.代码调用segue实现跳转
[self performSegueWithIdentifier:@"ShowRoleListSegue" sender:self];
同时可实现函数以在跳转前设置相关数据
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:@"ShowRoleListSegue"]) {
RoleListTableViewController *roleListTableViewController = [segue destinationViewController];
roleListTableViewController.loginData=loginData;
}
}
2.返回导航栏中上一个视图
[self.navigationController popViewControllerAnimated:YES];
3.使用故事版id实现跳转
UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"CustomerBaseInfoReadonly"];
[self.navigationController pushViewController:vc animated:YES];
4.try catch
@try
{
[self performSegueWithIdentifier:@"buyInfoDetailSegue" sender:self];
}
@catch (NSException *exception)
{
NSLog(@"Caught %@%@", [exception name], [exception reason]);
}
5.exit
- (void)exitApplication {
[UIView beginAnimations:@"exitApplication" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationTransition:UIViewAnimationCurveEaseOut forView:self.window cache:NO];
[UIView setAnimationDidStopSelector:@selector(animationFinished:finished:context:)];
self.window.bounds = CGRectMake(0, 0, 0, 0);
[UIView commitAnimations];
}
- (void)animationFinished:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
if ([animationID compare:@"exitApplication"] == 0) {
exit(0);
}
}
