Upload Song from iPod Library to Webserver using ASIHTTPRequest

1. in Your .h file

     #import

    and use include MPMediaPickerControllerDelegate

2. in .m file where your brows button

     MPMediaPickerController *picker =[[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeAnyAudio];

        picker.allowsPickingMultipleItems = YES;

Passcode Screen

There is a good example to create a Passcode screen.....

https://github.com/guicocoa/pinview

Open Doc Files from Another Application

1. in AppDelegate
if (launchOptions && [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey])
{

printf("Launch options:\n");
CFShow(launchOptions);
NSString *filePath = [NSString stringWithFormat:@"%@", (NSURL*)[launchOptions objectForKey:UIApplicationLaunchOptionsURLKey]];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSMutableArray *ArrTmp;
if ([[prefs objectForKey:@"DocArray"] count])
{
ArrTmp=[[prefs objectForKey:@"DocArray"] mutableCopy];
}
else
{
ArrTmp=[[NSMutableArray alloc] init];
}
[ArrTmp addObject:filePath];
[prefs setObject:ArrTmp forKey:@"DocArray"];

}


2. Add These Value in infoPList

Now it handle PDF,Doc,Xls,Ppt files and you have all open files in Userdefault named "DocArray"

Customize SplitViewController

Found a Good Example of Customize SliptViewController

MGSplitViewController

Add a image layer over camera

ImagePicker = [[UIImagePickerController alloc] init];
ImagePicker.delegate = self;
#if TARGET_IPHONE_SIMULATOR
ImagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
#elif TARGET_OS_IPHONE
ImagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
UIImageView *ImgOutline=[[UIImageView alloc] initWithFrame:CGRectMake(20, 28, 124, 404)];
ImgOutline.image=[UIImage imageNamed:@"outline.png"];
[ImagePicker.view addSubview:ImgOutline];
#endif

ImagePicker.navigationController.navigationBar.barStyle = UIBarStyleBlack;
ImagePicker.editing = YES;
[self presentModalViewController:ImagePicker animated:YES];
[ImagePicker release];

water effect with basic animation iphone sdk

I have found a good animation effect from google (Hidden Property)

CATransition *transition = [CATransition animation];
transition.type = @"rippleEffect";
transition.duration = 1.0f;
transition.timingFunction = UIViewAnimationCurveEaseInOut;
[self.view.layer addAnimation:transition forKey:@"transitionViewAnimation"];

we can use suckEffect and spewEffect similarly

A Static Array That can be used anywhere in Application

1. Create a new plist file


named it suppose DictArr

2.
now add values in in this plist as


3.
Now where you wants to access these value
use This code
NSString *path = [[NSBundle mainBundle] pathForResource:@"DictArr" ofType:@"plist"];
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
Arralbum=[dict objectForKey:@"ArrAlbum"];

Create Third Party Ads Through WebView

First we create a view controller named MyAds

in MyAds.h


@interface MyAds : UIViewController
{
IBOutlet UIWebView *Web_Ad;
NSString *formatStr;

UINavigationController *ng;
id parentController;

IBOutlet UIView *viewAdDesc;
IBOutlet UIWebView *Web_Ad_Detail;

}
-(void)initWithStr:(NSString*)str;
-(IBAction)btnCancel_Clicked:(id)sender;
@property(nonatomic, retain) id ParentController;
@property (nonatomic, retain) IBOutlet UINavigationController *ng;
@end


in MyAds.m

#import "MyAds.h"

@implementation MyAds
@synthesize ParentController = parentController;
@synthesize ng;

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
[Web_Ad setBackgroundColor:[UIColor clearColor]];
[Web_Ad setOpaque:NO];
[Web_Ad loadHTMLString:formatStr baseURL:[NSURL URLWithString:@"http://www.ashiphone.blogspot.com/"]];
}
-(void)initWithStr:(NSString*)str
{
formatStr=str;
[formatStr retain];
}

#pragma mark WebviewDelegate

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
NSLog(@"Page Start Loading");
if(webView==Web_Ad_Detail)
return YES;
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
NSURL *urlReq=[request URL];
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
if([urlReq isEqual:[NSURL URLWithString:@"http://www.ashiphone.blogspot.com/"]])
NSLog(@"YES");
else if(urlReq)
{
[Web_Ad stopLoading];
[Web_Ad loadHTMLString:formatStr baseURL:[NSURL URLWithString:@"http://www.ashiphone.blogspot.com/"]];
[parentController addSubview:viewAdDesc];
ng.navigationBarHidden = YES;
[Web_Ad_Detail loadRequest:request];
}
return YES;
}
- (void)webViewDidStartLoad:(UIWebView *)webView
{


}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{

}

-(IBAction)btnCancel_Clicked:(id)sender
{
[viewAdDesc removeFromSuperview];
ng.navigationBarHidden = NO;
}




- (void)viewDidUnload {
[super viewDidUnload];
}


- (void)dealloc {
[super dealloc];
}


@end




Now We Have To Include This View As SubView Where We Wants the Ads

MyAds* childObject = [[MyAds alloc]initWithNibName:@"MyAds" bundle:[NSBundle mainBundle]];
childObject.ParentController=self.view;
childObject.ng = self.navigationController;
[childObject initWithStr:formatStr];
// formatStr is NSString with HTML code

Crop Image From ImageView by touch

#pragma mark touches Working
-(void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
// get touch event
UITouch *touch = [[event allTouches] anyObject];
StartPoint = [touch locationInView:touch.view];

}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
// get touch event
UITouch *touch = [[event allTouches] anyObject];
EndPoint = [touch locationInView:touch.view];
}

-(IBAction)BtnDoneTouchInside
{

CGFloat width=EndPoint.x-StartPoint.x;
CGFloat hieght=EndPoint.y-StartPoint.y;
CGRect myImageRect = CGRectMake(StartPoint.x, StartPoint.y, width, hieght);
UIImageView *Img_Screen= [[UIImageView alloc] initWithFrame:myImageRect];

CGImageRef imageRef = CGImageCreateWithImageInRect([ImgMain.image CGImage], myImageRect);
// or use the UIImage wherever you like
[Img_Screen setImage:[UIImage imageWithCGImage:imageRef]];
CGImageRelease(imageRef);
[CropImageView addSubview:Img_Screen];

}

Build Multiple Projects From One Code

1--> Suppose your main project is MainProject.xcodeproj, The very first step is open project in Xcode and add a new target (TargetProj)



2--> edit MainProject info from Target

3--> change TargetProj-Info.plist in Info.plist File Property

4--> and change targetProj in Product Name

Create Object of class to use as a View

in ChildClass.h
@interface
{
UINavigationController *ng;
id parentController;
}
@property(nonatomic, retain) id ParentController;
@property (nonatomic, retain) IBOutlet UINavigationController *ng;

in ChildClass.m

@synthesize ParentController = parentController;
@synthesize ng;


in ParentClss.m

ChildClass* childObject = [[ChildClass alloc]initWithNibName:@"ChildView" bundle:[NSBundle mainBundle]];
childObject.ParentController=self;
childObject.ng = self.navigationController;
[childObject.view setFrame:CGRectMake(Frame)];
[YourView addSubview:childObject.view];
[self.view sendSubviewToBack:YourView];

UIKeyboardTypeNumberPad missing "return" key

I get the code from Google and modify it for DONE Button in UIKeyboardTypeNumberPad (works in iPhone 4 SDK)

- (void)textFieldDidBeginEditing:(UITextField *)textField {
if(textField==txtZipCode)
{
[self setViewMovedUp:YES];
[[NSNotificationCenter defaultCenter] addObserver: self
selector: @selector(keyboardDidShowOrHide:)
name: UIKeyboardDidShowNotification object:nil];

}
else
{

[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidShowNotification object:nil];
}



}
- (void) keyboardDidShowOrHide : (id) sender {
// create custom button
UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
doneButton.frame = CGRectMake(0, 427, 106, 53);
doneButton.adjustsImageWhenHighlighted = NO;
[doneButton setBackgroundImage:[UIImage imageNamed:@"doneup.png"] forState:UIControlStateNormal];
[doneButton setBackgroundImage:[UIImage imageNamed:@"donedown.png"] forState:UIControlStateHighlighted];
[doneButton addTarget:self action:@selector(doneButton:) forControlEvents:UIControlEventTouchUpInside];
UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
[tempWindow addSubview:doneButton];


}
-(void)doneButton:(id)sender
{
UIButton *btntmp=sender;
[btntmp removeFromSuperview];
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidShowNotification object:nil];
[self setViewMovedUp:NO];
[txtZipCode resignFirstResponder];
}
