I used MBCalendar kit framework. and successfully added in my project, but problem is that months and dates cant show simulator. only one top bar show in this weeks and year show. I attached my output snap shot please find this and show bellow. I want to successfully calendar show in UI. how it possible please help.
#import "ViewController.h"
#import "CalendarKit/CalendarKit.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
CKCalendarView *calendar = [CKCalendarView new];
[calendar setDelegate:self];
[calendar setDataSource:self];
[[self view] addSubview:calendar];
}
Follow my step:
Step 1: remove you are implement all related to MBCalendar.
Step 2: include CKDemoViewController.h & CKDemoViewController.m file in your project.
Step 3: set your view design class to CKDemoViewController.
check some file: https://github.com/BhadreshKathiriya/MBCalendar
- (IBAction)btnClick:(id)sender {
[self presentViewController:[[CKDemoViewController alloc] init] animated:YES completion:nil];
//Or
[self.navigationController pushViewController:[[CKDemoViewController alloc] init] animated:YES];
}

Essentially I'm working with 3 view controllers.
Main view which starts a download. (Webview based which passes the download).
Modal download controller. (Tab based).
Downloader (HCDownload).
In the main view my download gets passed like so:
//Fire download
[activeDL downloadURL:fileURL userInfo:nil];
[self presentViewController:vc animated:YES completion:nil];
activeDL is initialized in viewDidLoad:
activeDL = [[HCDownloadViewController alloc] init];
If I removed the presentViewController, it still downloads, which is fine. Then i tap my Downloads button, it brings up the controller which defines the tabs like so:
center = [[CenterViewController alloc] init];
activeDL = [[HCDownloadViewController alloc] init];
completedDL = [[DownloadsViewController alloc] init];
activeDL.tabBarItem = [[UITabBarItem alloc] initWithTitle:#"Active Downloads"
image:nil //[UIImage imageNamed:#"view1"]
tag:1];
completedDL.tabBarItem = [[UITabBarItem alloc] initWithTitle:#"Completed Downloads"
image:nil //[UIImage imageNamed:#"view3"]
tag:2];
[self setViewControllers:[NSArray arrayWithObjects:activeDL, completedDL, nil]];
However, it is not passing the current active download. I don't know if it's a initialization problem, or my tab issue of showing the current download.
From his github, he suggests to get the current number of downloads is to call: dlvc.numberOfDownloads which for me would be
[activeDL numberOfDownloads].
I call this in the the Downloader viewWillAppear but nothing shows.
Does anybody has any suggestions or have worked with this controller?
Any help would be appreciated.
When you call:
activeDL = [[HCDownloadViewController alloc] init];
You are creating a new download controller, which has its own internal downloads array. This library, as written, has no way to pass this information from one HCDownloadViewController object to another.
Tying downloads to VC's like this will cause problems -- I recommend you rewrite this code to split that apart.
To hack around it, try to create just one HCDownloadViewController object and pass it around.
Ok so with the last comment of the other answer, "Make activeDL a member variable instead of a local variable.", got me Googling and with some tinkering and bug fixing along the way I managed to get it all up and running perfect.
I declared it all in my AppDelegate.
AppDelegate.h
#interface SharedDownloader : HCDownloadViewController <HCDownloadViewControllerDelegate>
+ (id)downloadingView;
#end
AppDelegate.m
static HCDownloadViewController *active;
#implementation SharedDownloader
+ (id)downloadingView {
if (active == nil)
active = [[HCDownloadViewController alloc] init];
return active;
}
#end
Calling to the class for downloading in my main view controller:
-(id)init{
activeDL = [SharedDownloader downloadingView];
return self;
}
//Spot where I fire the download
if (navigationAction.navigationType == WKNavigationTypeLinkActivated) {
//More code here
[activeDL downloadURL:fileURL userInfo:nil];
}
Lastly in my tab bar controller:
-(id)init {
activeDL = [SharedDownloader downloadingView];
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
activeDL.tabBarItem = [[UITabBarItem alloc] initWithTitle:#"Active Downloads" image:nil] tag:2];
}
I believe that's all of it. In any case, thanks to Lou Franco for pointing me in the right direction.
I'm trying to track down the source of a bug in a cordova/phonegap plugin I wrote for creating email messages in app using a MFMailComposeViewController instance.
Everyone works fine the first time you present the the composer view. The user can dismiss the mail composer by sending the message or canceling. However, call presentViewController again renders the Cancel and Send buttons in the composer to become useless. My delegate for didFinishWithResult is never calling when pressing the inoperable buttons with the second view of the controller.
Below is simplified repro of what I'm seeing (the simple storyboard has a single view containing a single UIButton wired to my (IBAction)sendMail). What am I doing wrong in obj-c here? Shouldn't I be able to show a controller, dismiss it, and show it again?
ViewController.h:
#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
#interface ViewController : UIViewController
#end
ViewController.m:
#import "ViewController.h"
#interface ViewController () <MFMailComposeViewControllerDelegate>
#property (nonatomic, weak) IBOutlet UIButton *mailButton;
#property(nonatomic, strong) MFMailComposeViewController* picker;
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.picker = [[MFMailComposeViewController alloc] init];
self.picker.mailComposeDelegate = self;
}
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
[self dismissViewControllerAnimated:YES completion:NULL];
}
- (IBAction)sendMail
{
[self presentViewController:self.picker animated:YES completion:NULL];
}
#end
The reason for the behavior you are experiencing is the MFMailComposeViewController nils it's delegate when dismissed (maybe in -viewDidDisappear:).
- (void)viewDidLoad
{
[super viewDidLoad];
self.picker = [[MFMailComposeViewController alloc] init];
self.picker.mailComposeDelegate = self;
}
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
// Put a break point here **#breakpoint1**
[self dismissViewControllerAnimated:YES completion:NULL];
}
- (IBAction)sendMail
{
// Put a break point here **#breakpoint2**
[self presentViewController:self.picker animated:YES completion:NULL];
}
Place breakpoints at shown in the code comment above, run, and follow me as we step through your code.
Tap the interface button that calls your IBAction; execution halts at #breakpoint2
In the console type po self.picker
You'll see the mail compose VC instance is allocated
In the console type po self and then po self.picker.delegate
You'll see these both print the same object (the instance of your view controller)
Resume running, and tap the dismiss button on the mail compose view; execution halts at #breakpoint1
If you want to, inspect local and instance variables in console and then resume running
Tap the interface button that calls your IBAction (this is the second time); execution halts at #breakpoint2
In the console typ po self.picker.delegate
nil is printed to console
This delegate nil'ing behavior isn't documented in either Apple's MFMailComposeViewController class reference or the classes header. It's probably worth filing a bug report requesting clarification and better documentation. Because it's undocumented, the behavior may change in future releases. For that reason, the suggestions to create and destroy the VC as needed certainly seem like good common sense.
This bit me once before. It's caused by the composer being deallocated after it's done being dismissed. To solve this I would place the composer's creation either in viewDidAppear:, or in sendMail as Fahim suggested.
Additionally, you may want to consider wrapping these two lines in [MFMailComposeViewController canSendMail];
I would say take below lines to sendMail... it would work.
self.picker = [[MFMailComposeViewController alloc] init];
self.picker.mailComposeDelegate = self;
You will have as below.
- (void)viewDidLoad
{
[super viewDidLoad];
}
- (IBAction)sendMail
{
self.picker = [[MFMailComposeViewController alloc] init];
self.picker.mailComposeDelegate = self;
[self presentViewController:self.picker animated:YES completion:NULL];
}
#end
This is working with me...
I tried to use Cleaver, that is PhoneGap / Cordova as a component of an existing iOS application. I followed this step by step guide twice, without success.
My application can easily instantiate a web view, and i can pass content to it using the stringbyevaluatingjavascriptfromstring method, but as soon as i try to access PhoneGap API (navigator.compass, navigator.network, ...), nothing seems to work. console.log(navigator) shows no sign of Cordova objects (console.log does not output anything is Xcode, i'm using http://debug.phonegap.com/). The deviceready event is not triggered either.
In my html file, i include PhoneGap js file cordova-1.7.0rc1.js which i copied from another project (since /www folder is missing when you use PhoneGap as a component).
My ViewController.h imports <Cordova/CDVViewController.h>.
Here my ViewController.m
//
// ViewController.m
// CordovaComponent
//
#import "ViewController.h"
#interface ViewController (){
CDVViewController *cdvViewController ;
}
#end
#implementation ViewController
- (void)pushPhoneGap:(id)sender {
cdvViewController = [[CDVViewController alloc] init];
cdvViewController.wwwFolderName = #"www";
cdvViewController.startPage = #"index.html";
cdvViewController.view.frame = self.view.bounds;
cdvViewController.webView.delegate = self;
[self.navigationController pushViewController:cdvViewController animated:YES];
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIButton * button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setTitle:#"Push PhoneGap view" forState:UIControlStateNormal];
[button addTarget:self action:#selector(pushPhoneGap:) forControlEvents:UIControlEventTouchUpInside];
button.frame = CGRectMake(60, 50, 200., 50.);
[self.view addSubview:button];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
- (void)webViewDidFinishLoad:(UIWebView *)webView {
NSString *jsReturn = [cdvViewController.webView stringByEvaluatingJavaScriptFromString:#"setArray([1, 1, 2, 3, 5, 8, 13, 21, 34, 1]);"];
NSLog(jsReturn);
}
#end
Do you have an idea of what's happening ? Any help would be greatly appreciated !
Okay, after many hours of trying to solve this issue, I finally found what was going wrong.
This is the line that messed things up:
cdvViewController.webView.delegate = self;
You can't just override the delegate of the view controllers's web view. The original delegate has instantiation code which enables PhoneGap to run. Don't override it and everything will be fine !
If you want to get notified about webview events without breaking Cordova you could try something like this:
#interface WrappingWebViewDelegate : NSObject <UIWebViewDelegate>
#property (nonatomic,retain) id<UIWebViewDelegate> wrappedDelegate;
#end
#implementation WrappingWebViewDelegate
- (void)webViewDidStartLoad:(UIWebView*)theWebView {
[self.wrappedDelegate webViewDidStartLoad: theWebView];
// your code
}
// implement all other delegate methods and forward them to the wrapped delegate
[...]
#end
Usage like this:
cdvViewController = [[CDVViewController alloc] init];
WrappingWebViewDelegate wrappingDelegate = [[WrappingWebViewDelegate alloc] init];
wrappingDelegate.wrappedDelegate = cdvViewController.webView.delegate;
cdvViewController.webView.delegate = wrappingDelegate;
I haven't tested this, so you should be careful.
I´m trying to integrate ShareKit in my ios game.
Everything is working fine and the actionsheet is shown and I can interact with it but I´m not able to return the focus to my app when the sharekit action has finished (by closing the actionsheet or finishing any action).
I have tried in several ways but any has worked for me. What´s happening?
I´m not an expert programmer so I expect I´m missing something.
I´m
This is my .h
#import <UIKit/UIKit.h>
#import "SHK.h"
#import "SHKConfiguration.h"
#interface SocialWrapper: UIViewController{
}
- (id) init;
- (void) open;
- (void) dealloc;
#end
and .m
#import "SocializeWrapper.h"
#implementation SocialWrapper
- (id) init {
self=[super init];
DefaultSHKConfigurator *configurator = [[DefaultSHKConfigurator alloc] init];
[SHKConfiguration sharedInstanceWithConfigurator:configurator];
[SHK flushOfflineQueue];
return self;
}
- (void) open
{
NSString *someText = #"Hello Earth!";
SHKItem *item = [SHKItem text:someText];
// Get the ShareKit action sheet
SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];
UIWindow *window = [UIApplication sharedApplication].keyWindow;
[window addSubview:self.view];
[SHK setRootViewController:self];
[actionSheet showInView:self.view];
}
- (void) dealloc {
NSLog(#"SHK dealloc");
[self release];
[super dealloc];
}
#end
I´m calling it by using this wrapper
#import "SocializeWrapper.h"
SocialWrapper *socialize;
void SHKinit(void) {
NSLog(#"SHK Init");
socialize = [[SocialWrapper alloc] init];
}
void SHKopenWeb(void){
NSLog(#"SHK Open actionsheet");
[socialize open];
}
I´m working with ios 5, xcode 4.3.2 and the last sharekit version from the git.
I think I have to dissmiss my SocialWrapper once the actionsheet is closed but I don´t know how to capture that event, or even if this is correct. I´m stucked.
any help will be greatly appreciated.
UPDATE
As comment adviced, now the controller is on a category, using the actionsheet delegate, the focus can be regained when clicking the cancel´s actionsheet button. The problem still persists when an action is finished or cancelled. Don´t know how to capture that event.
This is my category code:
#import "SocialWrapper.h"
#implementation UIViewController (SocialController)
-(void) loadconfig
{
DefaultSHKConfigurator *configurator = [[DefaultSHKConfigurator alloc] init];
[SHKConfiguration sharedInstanceWithConfigurator:configurator];
[SHK flushOfflineQueue];
}
- (void) open
{
NSLog(#"Opening social button");
NSString *someText = #"Monkey Armada rules!";
SHKItem *item = [SHKItem text:someText];
// Get the ShareKit action sheet
SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];
UIWindow *window = [UIApplication sharedApplication].keyWindow;
[window addSubview:self.view];
[actionSheet setDelegate:self];
[SHK setRootViewController:self];
[actionSheet showInView:self.view];
}
- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
{
NSLog(#"SHK actionsheet dissmiss with button %d", buttonIndex);
if(buttonIndex == 4)
{
NSLog(#"SHK close actionsheet");
[self dismissViewControllerAnimated:YES completion:nil];
[self.view removeFromSuperview];
}
}
#end
Well since SHKActionSheet is a subclass of UIActionSheet you can set the delegate of that class to self to know when the dismissal happens.
Also, [self release]; in dealloc is complete misunderstanding of what release does, if you're in dealloc then releasing self won't do anything !
Learn the memory management rules.
I should also warn you that [window addSubview:self.view] is deprecated, you should not do that at all. In fact, I don't see a reason to wrap share kit stuff each view controller should be able to write that code easily. At worse you could put that code in a category on UIViewController if you don't want to rewrite the code every time.
So I have a subclass of UITableViewController that loads some data from the internet and uses MBProgressHUD during the loading process. I use the standard MBProgressHUD initialization.
HUD = [[MBProgressHUD alloc] initWithView:self.view];
[self.view addSubview:HUD];
HUD.delegate = self;
HUD.labelText = #"Loading";
[HUD show:YES];
This is the result:
.
Is there any way to resolve this issue, or should I just abandon MBProgressHUD?
Thanks!
My solution was pretty simple. Instead of using self's view, I used self's navigationController's view.
HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
[self.navigationController.view addSubview:HUD];
This should work for the OP because his picture shows he's using a UINavigationController. If you don't have a UINavigationController, you might add another view on top of your UITableView, and add the HUD to that. You'll have to write a little extra code to hide/show this extra view.
An unfortunate thing with this simple solution (not counting my idea adding another view mentioned above) means the user can't use the navigation controls while the HUD is showing. For my app, it's not a problem. But if you have a long running operation and the user might want to press Cancel, this will not be a good solution.
It's probably because self.view is a UITableView, which may dynamically add/remove subviews including the headers, which could end up on top of the HUD after you add it as a subview. You should either add the HUD directly to the window, or (for a little more work but perhaps a better result) you could implement a UIViewController subclass which has a plain view containing both the table view and the HUD view. That way you could put the HUD completely on top of the table view.
My solution was:
self.appDelegate = (kmAppDelegate *)[[UIApplication sharedApplication] delegate];
.
.
_progressHUD = [[MBProgressHUD alloc] initWithView:self.appDelegate.window];
.
[self.appDelegate.window addSubview:_progressHUD];
Works like a charm for all scenarios involving the UITableViewController. I hope this helps someone else. Happy Programming :)
Create a category on UITableView that will take your MBProgressHUD and bring it to the front, by doing so it will always appear "on top" and let the user use other controls in your app like a back button if the action is taking to long (for example)
#import "UITableView+MBProgressView.h"
#implementation UITableView (MBProgressView)
- (void)didAddSubview:(UIView *)subview{
for (UIView *view in self.subviews){
if([view isKindOfClass:[MBProgressHUD class]]){
[self bringSubviewToFront:view];
break;
}
}
}
#end
A simple fix would be to give the z-index of the HUD view a large value, ensuring it is placed in front of all the other subviews.
Check out this answer for information on how to edit a UIView's z-index: https://stackoverflow.com/a/4631895/1766720.
I've stepped into a similar problem a few minutes ago and was able to solve it after being pointed to the right direction in a different (and IMHO more elegant) way:
Add the following line at the beginning of your UITableViewController subclass implementation:
#synthesize tableView;
Add the following code to the beginning of your init method of your UITableViewController subclass, like initWithNibName:bundle: (the beginning of viewDidLoad might work as well, although I recommend an init method):
if (!tableView &&
[self.view isKindOfClass:[UITableView class]]) {
tableView = (UITableView *)self.view;
}
self.view = [[UIView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
self.tableView.frame = self.view.bounds;
self.tableView.contentInset = UIEdgeInsetsMake(0.0, 0.0, 0.0, 0.0);
[self.view addSubview:self.tableView];
Then you don't need to change your code you posted in your question any more. What the above code does is basically seperating the self.tableView from self.view (which was a reference to the same object as self.tableView before, but now is a UIView containing the table view as one might expect).
I've Just solved that issue manually , it has been 2 years since Chris Ballinger asked but maybe someone get used of what is going on here.
In UITableViewController i execute an HTTP method in viewDidLoad , which is running in background so the table view is loaded while the progress is shown causing that miss.
i added a false flag which is changed to yes in viewDidLoad, And in viewDidAppear something like that can solve that problem.
-(void) viewDidAppear:(BOOL)animated{
if (flag) {
[self requestSomeData];
}
flag = YES;
[super viewDidAppear:animated];
}
I had the same problem and decided to solve this by changing my UITableViewController to a plain UIViewController that has a UITableView as a subview (similar to what jtbandes proposed as an alternative approach in his accepted answer). The advantage of this solution is that the UI of the navigation controller isn't blocked, i.e. users can simply leave the ViewController in case they don't want to waiting any longer for your timely operation to finish.
You need to do the following changes:
Header file:
#interface YourViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
- (id)initWithStyle:(UITableViewStyle)style;
#end
Implementation file:
#interface YourViewController ()
#property (nonatomic, retain) UITableView *tableView;
#property (nonatomic, retain) MBProgressHUD *hud;
#end
#implementation YourViewController
#pragma mark -
#pragma mark Initialization & Memory Management
- (id)initWithStyle:(UITableViewStyle)style;
{
self = [super init];
if (self) {
// create and configure the table view
_tableView = [[UITableView alloc] initWithFrame:CGRectNull style:style];
_tableView.delegate = self;
_tableView.dataSource = self;
}
return self;
}
- (void)dealloc
{
self.tableView = nil;
self.hud = nil;
[super dealloc];
}
#pragma mark -
#pragma mark View lifecycle
- (void)loadView {
CGRect frame = [self boundsFittingAvailableScreenSpace];
self.view = [[[UIView alloc] initWithFrame:frame] autorelease];
// add UI elements
self.tableView.frame = self.view.bounds;
[self.view addSubview:self.tableView];
}
- (void)viewWillDisappear:(BOOL)animated
{
// optionally
[self cancelWhateverYouWereWaitingFor];
[self.hud hide:animated];
}
The method -(CGRect)boundsFittingAvailableScreenSpace is part of my UIViewController+FittingBounds category. You can find its implementation here: https://gist.github.com/Tafkadasoh/5206130.
In .h
#import "AppDelegate.h"
#interface ViewController : UITableViewController
{
MBProgressHUD *progressHUD;
ASAppDelegate *appDelegate;
}
In .m
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
appDelegate = (ASAppDelegate *) [UIApplication sharedApplication].delegate;
progressHUD = [MBProgressHUD showHUDAddedTo:appDelegate.window animated:YES];
progressHUD.labelText = #"Syncing To Sever";
[appDelegate.window addSubview:progressHUD];
This should work.
[MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
And to remove you can try
[MBProgressHUD hideHUDForView:self.navigationController.view animated:YES];
