I try to present a modal view (InfoViewController) from a navigation view controller(DateViewController).
I add a toolbar on top of InfoViewContoller's view. Now I want to add a title "Info" and a "Done" button on the toolbar.(The Done button will perform the infoDismissAction method)
Can anyone give me som tips? Thanks a lot!
Here's code of DateViewController.h
#import <UIKit/UIKit.h>
#import "InfoViewController.h"
@interface DateViewController : UIViewController
{
InfoViewController *infoViewController;
}
@property (nonatomic, retain) InfoViewController *infoViewController;
@end
DateViewController.m
- (IBAction)modalViewAction:(id)sender{
if (self.infoViewController == nil)
self.infoViewController = [[[InfoViewController alloc] initWithNibName:
NSStringFromClass([InfoViewController class]) bundle:nil] autorelease];
[self presentModalViewController:self.infoViewController animated:YES];
}
- (void)dealloc{
if (self.infoViewController != nil)
{
[infoViewController release];
}
[super dealloc];
}
- (void)viewDidLoad{
self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Info" style:UIBarButtonSystemItemPlay target:self action:@selector(modalViewAction:)] autorelease];
[modalBarButtonItem release];
[super开发者_如何学JAVA viewDidLoad];
}
Here's InfoViewController.m
- (IBAction)infoDismissAction:(id)sender{
[self.parentViewController dismissModalViewControllerAnimated:YES];
}
- (void)viewDidLoad {
UIToolbar *toolBar;
toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
toolBar.frame = CGRectMake(0, 0, 320, 50);
toolBar.barStyle = UIBarStyleDefault;
[toolBar sizeToFit];
[self.view addSubview:toolBar];
[toolBar release];
[backButton release];
[super viewDidLoad];
}
Try this code.
- (void)viewDidLoad {
UIToolbar *toolBar;
toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
toolBar.frame = CGRectMake(0, 0, 320, 50);
toolBar.barStyle = UIBarStyleDefault;
[toolBar sizeToFit];
UIBarButtonItem *flexibleSpace = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil] autorelease];
UIBarButtonItem *infoButton = [[[UIBarButtonItem alloc] initWithTitle:@"INFO" style:UIBarButtonItemStyleBordered target:self action:@selector(InfoAction:)] autorelease];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:@"DONE" style:UIBarButtonItemStyleBordered target:self action:@selector(doneAction:)];
NSArray *barButton = [[NSArray alloc] initWithObjects:flexibleSpace,infoButton,flexibleSpace,doneButton,nil];
[toolBar setItems:barButton];
[self.view addSubview:toolBar];
[toolBar release];
[barButton release];
barButton = nil;
[super viewDidLoad];
}
I'd recommend setting up another UINavigationController with your InfoViewController and present the navigation controller as your modal view.
To answer your question you'd want to fill in your UIToolbar like this:
- (void)viewDidLoad {
[super viewDidLoad];
UIToolbar *toolBar;
toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
toolBar.frame = CGRectMake(0, 0, 320, 50);
toolBar.barStyle = UIBarStyleDefault;
[toolBar sizeToFit];
[self.view addSubview:toolBar];
[toolBar release];
UIBarButtonItem* bbiInfo = [[UIBarButtonItem alloc] initWithTitle:@"Info" style:UIBarButtonItemStyleBordered target:self action:@selector(tappedInfoButton)];
UIBarButtonItem* flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem* bbiDone = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(tappedDoneButton)];
NSArray* items = [[NSArray alloc] initWithObjects:bbiInfo, flexibleSpace, bbiDone, nil];
[toolBar setItems:items];
[items release];
[bbiInfo release];
[flexibleSpace release];
[bbiDone release];
}
