Send Email with Attachment in iphone

Send Email with Attachment in iphone

1) In Xcode 4 goto the build phases tab for your target. Make sure you see MessageUI.framework. If it's not there click + to add a new framework.

2)In your interface file

#import <MessageUI/MFMailComposeViewController.h>


@interface YourViewController : UIViewController <MFMailComposeViewControllerDelegate> 

3)Add this Method

-(void)displayComposerSheet
{
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;
    [picker setSubject:@"Check My Image!"];

    // Set up recipients
    // NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.com"];
    // NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil];
    // NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"];

    // [picker setToRecipients:toRecipients];
    // [picker setCcRecipients:ccRecipients];  
    // [picker setBccRecipients:bccRecipients];

    // Attach an image to the email
    UIImage *myImage = YourImage;
    NSData *myData = UIImagePNGRepresentation(myImage);
    [picker addAttachmentData:myData mimeType:@"image/png" fileName:@"myImage.png"];

    // Fill out the email body text
    NSString *emailBody = @"My Pic";
    [picker setMessageBody:emailBody isHTML:NO];
    [self presentModalViewController:picker animated:YES];

    [picker release];
}

4) Implement the delegate method

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{  
    // Notifies users about errors associated with the interface
    switch (result)
    {
        case MFMailComposeResultCancelled:
            NSLog(@"Result: canceled");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"Result: saved");
            break;
        case MFMailComposeResultSent:
            NSLog(@"Result: sent");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"Result: failed");
            break;
        default:
            NSLog(@"Result: not sent");
            break;
    }
    [self dismissModalViewControllerAnimated:YES];
}

IPhone Custom Toolbar on Keyboard to Hide keyboard

IPhone Custom Toolbar on Keyboard

MY requirement was to work on numeric keys not alphabets so i have used Numeric Pad on UITEXTFIELD  and you all know that by default there is no button on numeric pad for hidden keyboard. You have to create Custom Button on ur numeric pad and call [numberTextField resignFirstResponder]; to hide numeric pad.

Solution
I have create a custom toolbar and have put two buttons on it 1) Apply and 2) Cancel. And created a method for both buttons.

- (void)viewDidLoad

{

    [super viewDidLoad];

    

    UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];

    numberToolbar.barStyle = UIBarStyleBlackTranslucent;

    numberToolbar.items = [NSArray arrayWithObjects:

                           [[UIBarButtonItem alloc]initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelNumberPad)],

                           [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],

                           [[UIBarButtonItem alloc]initWithTitle:@"Apply" style:UIBarButtonItemStyleDone target:self action:@selector(doneWithNumberPad)],

                           nil];

    [numberToolbar sizeToFit];

    numberTextField.inputAccessoryView = numberToolbar;

}

-(void)cancelNumberPad{

    [numberTextField resignFirstResponder];

    numberTextField.text = @"";

}

-(void)doneWithNumberPad{

    NSString *numberFromTheKeyboard = numberTextField.text;

    [numberTextField resignFirstResponder];

}

Thats it .. 
You can add Custom button on left side of 0 button. 

Core Plot Custom Themes in iPhone

Core Plot Custom Themes in iPhone

    CPTheme *theme = [CPTheme themeNamed:kCPPlainWhiteTheme]; 

    graph = (CPXYGraph *)[theme newGraph];

    

    graph.fill = [CPFill fillWithColor:[CPColor clearColor]];

    graph.plotAreaFrame.fill = [CPFill fillWithColor:[CPColor clearColor]];

You can apply following Themes in Core Plot

themeNamed:kCPPlainWhiteTheme
themeNamed:kCPTDarkGradientTheme
themeNamed:kCPTPlainBlackTheme
themeNamed:kCPTSlateTheme

ViewController.XIB

2 UIPicker and 1 UILabel

Connect Datasource and delegate of both picker to file owner.

Source Code : https://github.com/zohaibbrohi/UIPickerView.git

NOTE:-

Sorry for naming convention. You can achieve this multi picker by using one pickerView and divide it in number of columns.

In numberOfComponentsInPickerView return how many columns you want in one pickerView.

Loaded nib but the view outlet was not set

I was working on my iPhone project . And i copied Components from one nib file to another and when i run that project it gave this error. It happen when you copy nib components to another nib or sometime when you open new nib File.

Solution

• Open the XIB file causing problems
• Click on file's owner icon on the left bar (top one, looks like a yellow outlined box)
• If you don't see the right-hand sidebar, click on the third icon above "view" in your toolbar. This will show the right-hand sidebar
• In the right-hand sidebar, click on the third tab--the one that looks a bit like a newspaper
• Under "Custom Class" at the top, make sure Class is the name of the ViewController that should correspond to this view. If not, enter it
• In the right-hand sidebar, click on the last tab--the one that looks like a circle with an arrow in it
• You should see "outlets" with "view" under it. Drag the circle next to it over to the "view" icon on the left bar (bottom one, looks like a white square with a thick gray outline
• Save the xib and re-run

iPhone AlertView

AlertVIew in iphone with 2 buttons OK/YES/DELETE and NO/CANCEL .
// 2 Buttons
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Wait" message:@"Are you sure you want to delete this.  This action cannot be undone" delegate:self cancelButtonTitle:@"Delete" otherButtonTitles:@"Cancel", nil];
[alert show];

Performing Action on Both Buttons i.e Delete and Cancel.
buttonIndex 0 for Delete
buttonIndex 1 for Cancel

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { 
   if (buttonIndex == 0) { 
        NSLog(@"Delete Tapped."); 
    } 
    else if (buttonIndex == 1) { 
       NSLog(@"Cancel Tapped!"); 
    } 
}

Same u can perform action with single button alert view.

AlertVIew in iphone with 1 buttons OK/YES
// 1 Button
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Wait" message:@"No INTERNET CONNECTION" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
