I am using a TapkuMonthCalendarViewController in my application and when the calendar loads the color scheme of the calendar is not appearing normal on the simulator. Anyone else experience this?
I haven't messed with trying to set the background of anything and I have used this calendar before in other applications and it has never acted like this.
Any advice would be greatly appreciated.
This is the calendar view i see http://i.imgur.com/IwT9s.png
EDIT: I realized I forgot to include the bundle into my project! So this is the solution for all future tapku users.
You change calendar background than you can change the Calendar tile image .
OR You put this code on drawRect Method.
- (void) drawRect:(CGRect)rect
{
CGContextRef context = UIGraphicsGetCurrentContext();
//UIImage *tile = [UIImage imageWithContentsOfFile:TKBUNDLE(#"TapkuLibrary.bundle/Images/calendar/Month Calendar Date Tile.png")];
CGRect r = CGRectMake(0, 0, 46, 44);
//CGContextDrawTiledImage(context, r, tile.CGImage);
if(today > 0){
int pre = firstOfPrev > 0 ? lastOfPrev - firstOfPrev + 1 : 0;
int index = today + pre-1;
CGRect r =[self rectForCellAtIndex:index];
r.origin.y -= 7;
//[[UIImage imageWithContentsOfFile:TKBUNDLE(#"TapkuLibrary.bundle/Images/calendar/Month Calendar Today Tile.png")] drawInRect:r];
}
}

I am working on a project where i need to get the navigation bar height.I am getting the whole screen height using:
Helpers.ApplicationContext.ScreenHeight = (int)Resources.DisplayMetrics.HeightPixels / Resources.DisplayMetrics.Density;
Helpers.ApplicationContext.ScreenWidth = (int)Resources.DisplayMetrics.WidthPixels / Resources.DisplayMetrics.Density;
But I am not able to get the navigation bar height.
Can any one please suggest an idea to get the navigation bar height of my page.
Thanks in advance.
For iOS This may help you :
var navbarHeight = YourViewControllerInstance.NavigationController?.NavigationBar.Frame.Height;
For Android :
TypedArray styledAttributes = this.Theme.ObtainStyledAttributes(
new int[] { Android.Resource.Attribute.ActionBarSize });
var actionbarHeight = (int) styledAttributes.GetDimension(0, 0);
styledAttributes.recycle();
Above example gives Height in Pixel. Please find more refined sample as below which provide height in Pixel as well as DP:
TypedValue tv = new TypedValue();
int actionBarHeightInPixel = 0;
int actionBarHeightInDP = 0;
DisplayMetrics metrics = Resources.DisplayMetrics;
if (Theme.ResolveAttribute(Resource.Attribute.actionBarSize, tv, true))
{
actionBarHeightInPixel = TypedValue.ComplexToDimensionPixelSize(tv.Data, metrics);
actionBarHeightInDP = actionBarHeightInPixel / (int)metrics.Density;
}
I was searching through the Unity manual to see what they had for gradient effects and I found this:
Here is the link:
http://docs.unity3d.com/Manual/EditingValueProperties.html
However, I can't find this editor anywhere inside of Unity. I want to use this to apply a gradient to my background for a game. Does it exist!?
You do not have access to arbitrarily use color picker or gradient editor. For your purpose of making the background you have several options,
Change the Camera background color from the editor.
Use a Skybox, you can make your own skybox too.
If your game has a limited view, use a plane with a custom material.
Maybe this script shows how you can use Gradients. You need to add this script to one of your GameObject in your scene. And your Camera's tag is MainCamera .
This code based on this.
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class GradientHandler : MonoBehaviour {
public Camera camera;
public Gradient gradient;
// Use this for initialization
void Start () {
camera = GameObject.FindGameObjectWithTag("MainCamera").GetComponent<Camera>() as Camera; //Gets Camera script from MainCamera object(Object's tag is MainCamera).
GradientColorKey[] colorKey = new GradientColorKey[2];
GradientAlphaKey[] alphaKey = new GradientAlphaKey[2];
// Populate the color keys at the relative time 0 and 1 (0 and 100%)
colorKey[0].color = Color.red;
colorKey[0].time = 0.0f;
colorKey[1].color = Color.blue;
colorKey[1].time = 1.0f;
// Populate the alpha keys at relative time 0 and 1 (0 and 100%)
alphaKey[0].alpha = 1.0f;
alphaKey[0].time = 0.0f;
alphaKey[1].alpha = 0.0f;
alphaKey[1].time = 1.0f;
gradient.SetKeys(colorKey, alphaKey);
}
// Update is called once per frame
void Update () {
Debug.Log ("Time: "+Time.deltaTime);
camera.backgroundColor = gradient.Evaluate(Time.time%1);
}
}
I have an iOS app built on CoreData with tableviews and detailviews of the objects.
When in the detailview I would like to swipe horizontally to get the detail view of the next object.
I found PageControl and scrollview. But this is going to be for over 100 objects in the model.
Does anyone have a good sample of this or resource on how to do this.
Thanks
Michael
You could make individual views for each Core Data Object, then place those views on a UIScrollView.
You would need to set the contentSize:
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * allYourViews.count, scrollView.frame.size.height);
Then loop over all your views and add them to the scrollView:
for(int i = 0; i < allYourViews.count; i++) {
CGRect frame;
frame.origin.x = scrollView.frame.size.width * i;
frame.origin.y = 0;
frame.size = scrollView.frame.size;
if(allYourViews.count > 0) {
UIView* someView = (UIView *)allYourViews[i];
someView.frame = frame;
[scrollView addSubview:someView];
}
}
For more information and how to make it scroll nicely, check this tutorial:

( I don't know how this will perform :-)
I'm trying to scroll up my UISCrollView when the keyboard is shown
I use setContentOffset to shift the uiview up.
At the same time I want to decrease the height of my UISCrollView to (view height - keyboard height), so that the entire content view can be scrolled.
I apply both the changes in keyboardWillShow notification
When I actually bring the keyboard up in my app, the contents first get pushed up and then they are pushed down (which gives a flickering effect). I'm trying to smooth out both the transformations in one go..
Is it possible?
Code Below ---
- (void) keyboardWillShow {
CGPoint contentOffset = scrollView.contentOffset;
CGRect scrollViewFrame = scrollView.frame;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3];
if (contentOffset.y >= 0 && contentOffset.x >= 0) {
isContentOffset = YES;
contentOffset.y += screenShift;
[scrollView setContentOffset:contentOffset animated: NO];
}
scrollViewFrame.size.height = keyboardOrigin.y - self.view.frame.origin.y - toolbarHeight;
scrollView.frame = scrollViewFrame;
[UIView commitAnimations];
}
There is an option for animation when you setContentOffset for animation. here is the code that i use all the time
- (void)textViewDidBeginEditing:(UITextView *)textView
{
svos = scrollView.contentOffset;
CGRect rect = [textView bounds];
rect = [textView convertRect:rect toView:self.scrollView];
CGPoint point = rect.origin ;
point.x = 0 ;
[self.scrollView setContentOffset:point animated:YES];
doneButton.enabled = YES;
}
- (IBAction)donePressed
{
[scrollView setContentOffset:svos animated:YES];
[textview resignFirstResponder];
doneButton.enabled = NO;
}
It works fine for me.
Are you wrapping these changes in an animation block?
[UIView beginAnimations:#"resizeScroll" context:nil];
// make your changes to set and content offset
[UIView commitAnimations];
I think I have got a solution for this. You can handle the resize of the view in textViewDidBeginEditing method. You can just change the frame size of the scrollView to half by
CGRect tframe = myscrollView.frame;
tframe.size.height/=2;
myscrollView.frame = tframe;
and to initialize or handle the total length of the scrollview you can set the contentSize of the scrollView in the similar fashion as the frame was set in above snippet. for example
CGSize tsize = self.view.frame.size;
//here you can change the height and width of the scrollView
myscrollView.contentSize = tsize;
I hope this should do the trick for you. If it does please communicate.
Figured out the issue...
When the keyboard button was clicked, I was doing a becomeFirstResponder followed by a resignFirstResponder on keyboard view. This caused keyboardWillShow followed by keyboardWillHide and another keyboardWillShow notification, which brought the keyboard up, brought it back down and then up again.
Thanks to everybody who tried to help out.. and sorry the issue was pretty different...
I created programmatically a multi view iphone application.
when adding objects to a view, like a button for example. in position x = 0, y = 0
this results to x = 0, y = 20 in the iphone simulator.
this is the used code :
UIButton *btnGoToStartView = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btnGoToStartView.frame = CGRectMake(0, 0, 240, 30);
[btnGoToStartView setTitle:#"Btn Name" forState:UIControlStateNormal];
[btnGoToStartView addTarget:self action:#selector(myBtnAction) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btnGoToStartView];
In the other hand, when I'm placing a button using Interface Builder in position x = 0, y = 0 the result is good.
Till now I didn't found the real reason for this vertical shifting.
Thanks in advance for your hints.
Regards.
It's Ok, I found the solution.
It's a problem of the UIView not the control.
in Interface builder, I opened the MainWindow.xib then I modified the attribute Layout in the inspector window.
I checked [wants full screen].
That's all.
