【问题描述】：

ActionsViewController *actionsViewController = [AppLibrary createActionsViewController];
actionsViewController.actionDelegate = self;
actionsViewController.supportedActionTypes = @[[[SupportedAction alloc] initWithActionType:ActionTypeEdit mediaTypes:@[kTypePNG]]];

[actionsViewController setWhitelistedSubTypes:@[@"adjust", @"filter", @"healing"]];

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) 
    self.actionsNavigationController = [[UINavigationController alloc] initWithRootViewController:actionsViewController];
    [self presentViewController:self.actionsNavigationController animated:YES completion:nil];

【问题讨论】：

- (IBAction)go:(id)sender ;

如何从按钮调用此代码？

【参考方案1】：

把这个加进去

-(IBAction)go:(id)sender

ActionsViewController *actionsViewController = [AppLibrary createActionsViewController];
actionsViewController.actionDelegate = self;
actionsViewController.supportedActionTypes = @[[[SupportedAction alloc] initWithActionType:ActionTypeEdit mediaTypes:@[kTypePNG]]];

[actionsViewController setWhitelistedSubTypes:@[@"adjust", @"filter", @"healing"]];

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) 
    self.actionsNavigationController = [[UINavigationController alloc] initWithRootViewController:actionsViewController];
    [self presentViewController:self.actionsNavigationController animated:YES completion:nil];
