I want in my app that email id is written in text form off-course, but that text should be clickable. And on clicking that a pop up should appear having two fields and two buttons. The two fields should be editable so as to type "from" and "message body" into it.The two buttons are of send and cancel.
please help.
just create button with your Email Address and set selector on it like bellow...
UIButton *BtnEmail = [UIButton buttonWithType:UIButtonTypeCustom];
[BtnEmail setBackgroundColor:[UIColor clearColor]];
[BtnEmail setTitle:#"YourEmailId" forState:UIControlStateNormal];
BtnEmail.frame = CGRectMake(85, 100, 150, 39 );/// set your frame
[BtnEmail addTarget:self action:#selector(EmailButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:BtnEmail];
and in action event (Method) write this code.. and just add these two delegate in .h file MFMessageComposeViewControllerDelegate and MFMailComposeViewControllerDelegate and also 1 framework name is MessageUI.framework
-(IBAction)EmailButtonClicked:(id)sender{
if ([MFMailComposeViewController canSendMail]) {
appDelegate.imgCapture = [self captureView];
[appDelegate.imgCapture retain];
MFMailComposeViewController *mailComposeViewController = [[MFMailComposeViewController alloc] init];
NSString *mailBody = #"Set Your Body Message";
[mailComposeViewController setMessageBody:mailBody isHTML:NO];
mailComposeViewController.mailComposeDelegate = self;
[self presentViewController:mailComposeViewController animated:YES completion:nil];
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"e-Mail Sending Alert"
message:#"You can't send a mail"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
}
and these bellow method is Delegate method..
#pragma mark - MFMessage Delegate
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
[self dismissViewControllerAnimated:YES completion:nil];
}
i hope this help you...

I've added UITextView as a sub view of UIAlertView, I've added UIToolBar with a Done button (using UIBarButtonItem) as inputAccessoryView to allow user to resign keyboard`. It's just working fine in iOS6.0. And not in iOS5.0.
I've break point and checked in all the way I can, for reconfirming my self, I've made a sample project and checked the same in both the iOS versions, and the problem is same.
Here's the code, that's messing with me,
-(UIToolbar *)accessoryView
{
if (!accessoryView) {
accessoryView = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44.0)];
UIBarButtonItem *btn = [[UIBarButtonItem alloc]initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(hideKeyBoard)];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
accessoryView.items = [NSArray arrayWithObjects:flexibleSpace,btn, nil];
[accessoryView setTintColor:[[UIColor blackColor]colorWithAlphaComponent:0.5]];
}
return accessoryView;
}
-(IBAction) showAlertWithTextView: (id) sender
{
UIAlertView *alert = [[UIAlertView alloc] initWithFrame:CGRectMake(0, 50, 320, 200)];
alert.title = nil;
alert.message = nil;
alert.delegate = self;
//textview I've added in .h file
textView = [[UITextView alloc] initWithFrame:alert.bounds];
textView.text = #"This is a UITextView";
textView.keyboardAppearance = UIKeyboardAppearanceAlert;
textView.editable = YES;
textView.inputAccessoryView = [self accessoryView];
[alert addSubview:textView];
[alert show];
}
- (void)hideKeyBoard {
[textview resignFirstResponder];
//[self.view endEditing:YES]; //this is also not worked
}
Here's list of steps I'm doing,
Showing Alert with Textview
Focus to Textview
Tap on Done button to resign TextView
Its not resigning in iOS5 but resigning in iOS6
Any idea? What's going wrong?
Actually your textview is not the first responder. The first responder is your alertView.
So you should try this....
[textField resignFirstResponder];
[alertView resignFirstResponder];
To use this code you must declare your alertView object in your.h file
I've solved it, as solution given by #iOS Developer, but as I've so many UIAlertView objects to handle, I've added a property of UIAlertView in delegate, and assigning it with the object of my alertview like this,
-(void)willPresentAlertView:(UIAlertView *)alertView
{
//set current alertview
[[AppDelegate sharedDelegate] setCurrentAlertView:alertView];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
//will remove current alertview reference
[[AppDelegate sharedDelegate] setNilCurrentAlertView];
}
- (void)hideKeyBoard {
[textView resignFirstResponder];
//when need to resign UITextView, get current alertview object
UIAlertView *alertView = [[AppDelegate sharedDelegate] getCurrentAlertView];
if(alertView) {
[alertView resignFirstResponder];
}
}
In AppDelegate.m file,
#pragma mark - UIAlertView Resign
- (void) setCurrentAlertView:(UIAlertView *)alert{
self.alertObj = alert;
}
- (void) setNilCurrentAlertView {
self.alertObj = nil;
}
- (UIAlertView *)getCurrentAlertView {
return (UIAlertView *)self.alertObj;
}
As it is somewhat late but I am wondering that your code will not work in iOS7 or not as from iOS7 onwards UIAlertView is not allowing to add any subview (As you are adding UITextView as subview of UIAlertView).
If your requirement is not to compulsory using the UITextView then you can use UIAlertView with following configuration with default textfield in alert.
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Title"
message:#"Message"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok", nil];
[message setAlertViewStyle:UIAlertViewStylePlainTextInput];
[message show];
And you can get value of this textfield in delegate of UIAlertView like this,
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
[alertView textFieldAtIndex:0].text;
}
I want to display UIProgressView on UIAlertView for displaying the processing of uploading of the file. But I have searched too much and also find on that link but sill unable to do that. I don't get idea from this
If anyone know the easiest way to do that then please let me know.
I've had problems doing this, and ended up with this:
av = [[UIAlertView alloc] initWithTitle:#"Running" message:#"" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil];
progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];
progressView.frame = CGRectMake(0, 0, 200, 15);
progressView.bounds = CGRectMake(0, 0, 200, 15);
progressView.backgroundColor = [UIColor blackColor];
[progressView setUserInteractionEnabled:NO];
[progressView setTrackTintColor:[UIColor blueColor]];
[progressView setProgressTintColor:[UIColor redColor]];
[av setValue:progressView forKey:#"accessoryView"];
[av show];
Try this code...
UIAlertView *av = [[UIAlertView alloc] initWithTitle:#"" message:#"" delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];
UIProgressView *pv = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];
pv.frame = CGRectMake(20, 20, 200, 15);
pv.progress = 0.5;
[av addSubview:pv];
[av show];
While this doesn't quite answer your question, try MBProgressHud, a third-party control that has this feature built-in. The examples supplied on Github should get you up to speed pretty quickly.
Try this code. Put YES for activity indicator and NO for progressView
- (void) createProgressionAlertWithMessage:(NSString *)message withActivity:(BOOL)activity
{
progressAlert = [[UIAlertView alloc] initWithTitle: message
message: #"Please wait..."
delegate: self
cancelButtonTitle: nil
otherButtonTitles: nil];
// Create the progress bar and add it to the alert
if (activity) {
activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
activityView.frame = CGRectMake(139.0f-18.0f, 80.0f, 37.0f, 37.0f);
[progressAlert addSubview:activityView];
[activityView startAnimating];
} else {
progressView = [[UIProgressView alloc] initWithFrame:CGRectMake(30.0f, 80.0f, 225.0f, 90.0f)];
[progressAlert addSubview:progressView];
[progressView setProgressViewStyle: UIProgressViewStyleBar];
}
[progressAlert show];
[progressAlert release];
}
Why not make use of the alerviewdelegate method
- (void)willPresentAlertView:(UIAlertView *)alertView
The advantage of this is we can see what size the alertview will actually be on screen, as iOS has precomputed this at this point, so no need for magic numbers - or overriding the class which Apple warn against !
And as of iOS7 I remember reading some document from Apple saying not to hard code any frame sizes but to always compute them from the app, or something along those lines ?
- (void)willPresentAlertView:(UIAlertView *)alertView
{
CGRect alertRect = alertview.bounds;
UIProgressView *loadingBar = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleBar];
loadingBar.bounds = CGRectMake(0, 0, alertRect.width, HEIGHT_YOU_WANT);
// Do what ever you want here to set up the alertview, as you have all the details you need
// Note the status Bar will always be there, haven't found a way of hiding it yet
// Suggest adding an objective C reference to the original loading bar if you want to manipulate it further on don't forget to add #import <objc/runtime.h>
objc_setAssociatedObject(alertView, &myKey, loadingBar, OBJC_ASSOCIATION_RETAIN); // Send the progressbar over to the alertview
}
To pull reference to the loading bar in
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
Then use
UIProgressView *loadingBar = objc_getAssociatedObject(alertView, &myKey);
Remember to have defined
#import <objc/runtime.h>
static char myKey;
At the top of your class declaration
This is create a alert view
UIAlertController* alert=[UIAlertController alertControllerWithTitle:#"Message" message:#"This is test" preferredStyle:UIAlertControllerStyleAlert];
now add textfield
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField)
{
textField.placeholder=#"Enter Text label";
[textField setBorderStyle:UITextBorderStyleRoundedRect];
textField.backgroundColor=[UIColor whiteColor];
}];
and added it on view
[self presentViewController:alert animated:YES completion:nil];
I have one UIAlertView containing one UITextField with ok and cancel button. When I click on ok button i am calling webService. I want to return keyboard before calling webservice. Keyboard is not returning till response is not coming from webservice. Because of that half screen not visible to user during loading webservice. Here is my code which i did.
UIAlertView *alertview = [[UIAlertView alloc] initWithTitle:#"Forgot Password" message:#" " delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
// Adds a username Field
alertEmailtextfield = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 29.0)];
alertEmailtextfield.layer.cornerRadius = 07.0f;
[alertEmailtextfield setBorderStyle:UITextBorderStyleRoundedRect];
alertEmailtextfield.placeholder = #"Enter Email";
[alertEmailtextfield setBackgroundColor:[UIColor whiteColor]];
alertEmailtextfield.autocapitalizationType =UITextAutocapitalizationTypeNone; //For Making Caps Off
[alertview addSubview:alertEmailtextfield];
[alertview show];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 1) {
if ([alertEmailtextfield.text length] != 0) {
if (![self validEmail:alertEmailtextfield.text]) {
[AlertView UIAlertView:#"Enter email is not correct"];
}else{
//[alertEmailtextfield resignFirstResponder];
[NSThread detachNewThreadSelector:#selector(startSpinner) toTarget:self withObject:nil];
Boolean isForgotPassword = [serverConnection forgotPassword:alertEmailtextfield.text];
if (isForgotPassword) {
NSLog(#"Mail is send");
[AlertView UIAlertView:#"New password is send to your mail"];
[spinner stopAnimating];
}else{
[AlertView UIAlertView:#"User does not exist"];
[spinner stopAnimating];
}
}
}else{
[AlertView UIAlertView:#"Text Field should not be empty"];
}
}
}
Please if any one knows how to return keyboard in UIAlertView's UITextField, help me.
Your UI is stuck waiting for your webservice to complete. Call your webservice in a background thread your problem will be solved.
[self performSelectorInbackgroundThread:#selector(yourWebservice)];
Might be u are doing both task (webservice call and keyboard resinging) in same main thread so untill ur data is not loading from server keyboard is not resign from view. call weservice method in background thread like.
-(void)alertView:(CustomAlert *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
[textField resignFirstResponder];
UPdate
[self performSelectorInBackground:#selector(yourWebservice) withObject:nil];
}
In my app, I have an abouts page. I would like to place a round rect button which when I press it, I would be able to send an email to the company with an embedded email address.
Are there any tutorials to do this?
Thanks in advance.
Here's the code:
Obj-C:
(Don't forget to add the messageUI framework to your project!!!)
First import the message library:
#import <MessageUI/MessageUI.h>
Then mark your self as a delegate like this:
#interface MYViewController () <MFMailComposeViewControllerDelegate>
Then to pull up the composer (if user has email set up on their device):
- (IBAction)emailButtonPressed:(id)sender {
if ([MFMailComposeViewController canSendMail]) {
MFMailComposeViewController *composeViewController = [[MFMailComposeViewController alloc] initWithNibName:nil bundle:nil];
[composeViewController setMailComposeDelegate:self];
[composeViewController setToRecipients:#[#"example#email.com"]];
[composeViewController setSubject:#"example subject"];
[self presentViewController:composeViewController animated:YES completion:nil];
}
}
Then to handle the delegate callback and dismiss the composer:
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
//Add an alert in case of failure
[self dismissViewControllerAnimated:YES completion:nil];
}
SWIFT 3:
Import the relevant library:
import MessageUI
Mark your view controller as a delegate like so:
class MyViewController: UIViewController, MFMailComposeViewControllerDelegate {
Pull up composer (if user has email set up on their device):
#IBAction func emailButtonAction(_ sender: UIButton) {
if MFMailComposeViewController.canSendMail() {
let mail = MFMailComposeViewController()
mail.mailComposeDelegate = self
mail.setToRecipients(["example#gmail.com"])
mail.setSubject("Example Subject")
mail.setMessageBody("<p>Test</p>", isHTML: true)
present(mail, animated: true)
}
}
Handle delegate callback and dismiss the composer:
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true)
}
You have to link against the MessageUI framework and use the class MFMailComposeViewController. Don't forget to import the framework (#import <MessageUI/MessageUI.h>).
The documentation with sample code: http://developer.apple.com/library/ios/#documentation/MessageUI/Reference/MFMailComposeViewController_class/Reference/Reference.html
Here is the code to open Mail Composer in iOS:
Source:http://sickprogrammersarea.blogspot.in/2014/03/open-mail-composer-programmatically-in.html
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(send:) forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Send Mail" forState:UIControlStateNormal];
button.frame = CGRectMake(100.0, 350.0, 100.0, 40.0);
[self.view addSubview:button];
}
- (void) send:(id)sender{
MFMailComposeViewController *comp=[[MFMailComposeViewController alloc]init];
[comp setMailComposeDelegate:self];
if([MFMailComposeViewController canSendMail])
{
[comp setToRecipients:[NSArray arrayWithObjects:#"imstkgp#gnail.com", nil]];
[comp setSubject:#"From my app"];
[comp setMessageBody:#"Hello bro" isHTML:NO];
[comp setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentViewController:comp animated:YES completion:nil];
}
else{
UIAlertView *alrt=[[UIAlertView alloc]initWithTitle:#"" message:#"" delegate:nil cancelButtonTitle:#"" otherButtonTitles:nil, nil];
[alrt show];
}
}
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
if(error)
{
UIAlertView *alrt=[[UIAlertView alloc]initWithTitle:#"" message:#"" delegate:nil cancelButtonTitle:#"" otherButtonTitles:nil, nil];
[alrt show];
[self dismissModalViewControllerAnimated:YES];
}
else{
[self dismissModalViewControllerAnimated:YES];
}
}
Lots of them. You can start here and here. And check stackoverflow right here.
Here is the code I have to create an UIAlertView with a textbox.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Enter A Username Here" message:#"this gets covered!"
delegate:self cancelButtonTitle:#"Dismiss" otherButtonTitles:#"OK!", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)];
CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60);
[alert setTransform:myTransform];
alert.tag = kAlertSaveScore;
[myTextField setBackgroundColor:[UIColor whiteColor]];
[alert addSubview:myTextField];
[alert show];
[alert release];
[myTextField release];
My question is, how do I get the value from the textfield in:
- (void) alertView:(UIAlertView *) actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
}
I know I can get the standard stuff for the alertview such as actionSheet.tag and such, but how would I get the above created textfield?
#interface MyClass {
UITextField *alertTextField;
}
#end
And instead of declaring it locally, just use that.
//...
alertTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)];
//...
- (void) alertView:(UIAlertView *) alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
NSString *text = alertTextField.text;
alertTextField = nil;
}
Just give it a tag, and find it using the tag later. So, using your code:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Enter A Username Here" message:#"this gets covered!"
delegate:self cancelButtonTitle:#"Dismiss" otherButtonTitles:#"OK!", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)];
CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60);
[alert setTransform:myTransform];
alert.tag = kAlertSaveScore;
// Give the text field some unique tag
[myTextField setTag:10250];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[alert addSubview:myTextField];
[alert show];
[alert release];
[myTextField release];
Then, in the call-back, wherever that happens to be and without having to worry about memory management or state management of the text field:
- (void) alertView:(UIAlertView *) actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
// Get the field you added to the alert view earlier (you should also
// probably validate that this field is there and that it is a UITextField but...)
UITextField* myField = (UITextField*)[actionSheet viewWithTag:10250];
NSLog(#"Entered text: %#", [myField text]);
}
