UIAlertView addSubview in iOS7
(8 answers)
Closed 9 years ago.
I am trying to add an image in a UIAlertView in this way:
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:#"Accept Connection?"
message:[NSString stringWithFormat:#"%# wants to connect with you", newStr]
delegate:self
cancelButtonTitle:#"No"
otherButtonTitles:#"Yes", nil];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 100, 100, 50)];
NSString *imgPath = [[NSString alloc] initWithString:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"BluetoothDeviceiPhone.png"]];
UIImage *yourImage = [[UIImage alloc] initWithContentsOfFile:imgPath];
[imageView setImage:yourImage];
[alertView addSubview:imageView];
[alertView show];
alertView.tag = 2;
The image is not showing though, neither a space is showing, just the text. Why??
check this sample code it also running in ios7 and prior

I am working on an app. I tried to add an UIIMage to UIAlertView using below code,
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Instruction"
message:#"Please TAP on Screen to Continue."
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(220, 50, 32, 32)];
UIImage *img = [UIImage imageNamed:#"pendingImg.png"];
[imageView setImage:img];
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
[alert setValue:imageView forKey:#"accessoryView"];
}else{
[alert addSubview:imageView];
}
[alert show];
My image is of dimension 32 × 32 pixels. I am getting the alert as shown,
Should I add constraints to this image? or anything else to be made?
You can set imageView contentMode to UIViewContentModeScaleAspectFit,
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Instruction"
message:#"Please TAP on Screen to Continue."
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(220, 50, 32, 32)];
UIImage *img = [UIImage imageNamed:#"pendingImg.png"];
imageView.contentMode = UIViewContentModeScaleAspectFit;
[imageView setImage:img];
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
[alert setValue:imageView forKey:#"accessoryView"];
}else{
[alert addSubview:imageView];
}
[alert show];
Might be Anbu.Karthik suggested link comment also helpful for you.
try this
UIAlertView* alert = [UIAlertView alloc] initWithTitle: #"Instruction" message: #"Please TAP on Screen to Continue." delegate:nil cancelButtonTitle:#"no" otherButtonTitles:#"yes", nil];
UIImage* img = [UIImage imageNamed:#"pendingImg.png"];
UIImageView* imgview = [UIImageView alloc] initWithFrame:CGRectMake(0, 0, img.size.width, img.size.height)];
[img setImage:imgMyImage];
[alert setValue: imgview forKey:#"accessoryView"];
[alert show];
UIAlertView* alert = [[UIAlertView alloc] initWithTitle: #"Instruction" message: #"Please TAP on Screen to Continue." delegate:nil cancelButtonTitle:#"no" otherButtonTitles:#"yes", nil];
UIImage* img = [UIImage imageNamed:#"add.png"];
UIImageView* imgview = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, img.size.width, img.size.height)];
[imgview setImage:img];
[alert setValue: imgview forKey:#"accessoryView"];
[alert show];
}
I would like to automatically select text that I add to a UIAlertView. I thought this would work but it doesn't:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:...];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField *tf = [alert textFieldAtIndex:0];
tf.text = #"Some text";
[tf selectAll:nil];
Can we programmatically insert text in UIAlertView's textfield, iOS7
Created UIAlertView with textinput in IOS7.
Can anyone help me with "inserting text programatically in textfield"?
Hopefully this will give answer for your question.
UIAlertView *alertView = [[UIAlertView alloc] init];
alertView.delegate = self;
alertView.title = #"Enter Info";
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView addButtonWithTitle:#"Cancel"];
[alertView addButtonWithTitle:#"OK"];
[alertView textFieldAtIndex:0].text = #"My Text";
[alertView show];
You can achieve this by using this code
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"" message:#"whatever you like" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:#"Cancel", nil];
alert.alertViewStyle=UIAlertViewStylePlainTextInput;
[alert textFieldAtIndex:0].text=#"Hello";
[alert show];
and result will be like this:
Please try to use like this..
UIAlertView* av = [[UIAlertView alloc] init];
[av setDelegate:self];
[av setTitle:#"Hi"];
[av setMessage:nil];
[av addButtonWithTitle:#"Cancel"];
[av addButtonWithTitle:#"OK"];
av.alertViewStyle = UIAlertViewStylePlainTextInput;
[av textFieldAtIndex:0].text = #"Text";
You can use text property to set text inside textfield.
textFiled.text = #"YOUR TEXT";
I want to create an alertview with two uitextfields inside of it.
method:
//show alertview for file input
- (IBAction)showAddFiles:(id)sender {
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Enter File Details"
message:nil
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Add", nil];
UITextField *textFieldDescription = [message textFieldAtIndex:0];
textFieldDescription.placeholder = #"File Description : Ex. Acat Briefing";
UITextField *textFieldFileName = [message textFieldAtIndex:1];
textFieldFileName.placeholder = #"Exact File Name : Ex. acat.pdf";
[message show];
}
//make sure file description is long enoguh
- (BOOL)alertViewShouldEnableFirstOtherButton:(UIAlertView *)alertView
{
NSString *inputText = [[alertView textFieldAtIndex:0] text];
if( [inputText length] <= 15 && [inputText length] >= 4)
{
return YES;
}
else
{
return NO;
}
}
//handle add button
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *title = [alertView buttonTitleAtIndex:buttonIndex];
if([title isEqualToString:#"Add"])
{
UITextField *fileDescription = [alertView textFieldAtIndex:0];
UITextField *fileName = [alertView textFieldAtIndex:1];
NSLog(#"Desc: %#\nName: %#", fileDescription.text, fileName.text);
}
}
Error:
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'textFieldIndex (0) is outside of the bounds of the array of text fields'
Why I do get this error, how can I create two uitextfields in an alert view?
=========Working Solution ===========
Thanks for the answer below works when you only need two plain textfields
//show alertview for file input
- (IBAction)showAddFiles:(id)sender {
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Enter File Details"
message:nil
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Add", nil];
[message setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];
UITextField *fileDescription = [message textFieldAtIndex:0];
fileDescription.placeholder=#"Ex. acat.pdf";
[[message textFieldAtIndex:1] setSecureTextEntry:NO];
UITextField *fileName= [message textFieldAtIndex:1];
fileName.placeholder=#"Ex. Acat Briefing";
[message show];
}
After you allocated the "message" alert view. Add this to your code:
[message setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];
[[message textFieldAtIndex:1] setSecureTextEntry:NO];
This will make your alert view two text field inside.
The error you received occurs because there are no text fields in your UIAlertView, 'message'. The instance method "textFieldAtIndex" exists to access textFields in a UIAlertView that is created with a specific style, like UIAlertViewStylePlainTextInput, UIAlertViewStyleSecureTextInput, or UIAlertViewStyleLoginAndPasswordInput. These styles are set on the property "alertViewStyle". For example:
[message setAlertViewStyle:UIAlertViewStylePlainTextInput];
You may use "textFieldAtIndex" after setting this property, but unfortunately it looks as if none of these styles suit your needs.
What I've done before is to create a default styled UIAlertView (like you've already done), and add UITextFields as subviews to the UIAlertView.
For Example:
//Create the alert then add any labels and text fields as subviews.
//You can pad out an alertView by adding newline characters in the message. This will
// give the alertView more space to draw the text fields.
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Two Text Field Alert"
message:#"\n\n\n\n\n"
delegate:self
cancelButtonTitle:#"CanceL"
otherButtonTitles:#"OK", nil];
UITextField *textField1 = [[UITextField alloc] initWithFrame:CGRectMake(16,83,252,25)];
textField1.borderStyle = UITextBorderStyleRoundedRect;
textField1.keyboardAppearance = UIKeyboardAppearanceAlert;
textField1.delegate = self;
[message addSubview:textField1];
UITextField *textField2 = [[UITextField alloc] initWithFrame:CGRectMake(16,112,252,25)];
textField2.placeholder = #"Password";
textField2.borderStyle = UITextBorderStyleRoundedRect;
textField2.keyboardAppearance = UIKeyboardAppearanceAlert;
textField2.delegate = self;
[message addSubview:textField2];
[message show];
[message release];
[textField2 release];
[textField1 release];
It's a lot more verbose and messy to do a login this way as opposed to the alertView styles, but you can adapt this as you see fit to add any number of subviews to an alert view.
Edited to simplify example.
You're getting that error because the UIAlertView does not contain any textfields. Since the alert view's textfield collection is empty when you try to call [alertView textFieldAtIndex:0], you end up with the NSInvalidArgumentException and a crash.
We are allowed to create only two text fields in alertview. Here:
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:#"Change Password"
message:#""
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"OK", nil];
alert.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;
UITextField * alertTextField1 = [alert textFieldAtIndex:0];
alertTextField1.keyboardType = UIKeyboardTypeDefault;
alertTextField1.placeholder = #"Type Current password";
[[alert textFieldAtIndex:0] setSecureTextEntry:YES];
UITextField * alertTextField2 = [alert textFieldAtIndex:1];
alertTextField2.keyboardType = UIKeyboardTypeDefault;
alertTextField2.placeholder = #"Type New Password";
[alert show];

I want to share a photo from the Internet to WECHAT, but after I press the share button , nothing happens , I am new to Objective-C and I am unable to figure out the problem myself.Hearing that there are a lot of experts here,so is there some guy can help me solve this one? thanks in advance. here are the codes:
UIImage * image = [[[imageTitleArray objectAtIndex:initIndex] albumImageView] image];
WXMediaMessage *message = [WXMediaMessage message];
[message setThumbImage: image];
WXImageObject *ext = [WXImageObject object];
ext.imageData = UIImageJPEGRepresentation(image,1);
message.mediaObject = ext;
SendMessageToWXReq* req = [[[SendMessageToWXReq alloc] init]autorelease];
req.bText = NO;
req.message = message;
[WXApi sendReq:req];
Try the following method
- (void) sendImageContentToWeixin:(UIImage *)image {
//if the Weixin app is not installed, show an error
if (![WXApi isWXAppInstalled]) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:#"The Weixin app is not installed" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
return;
}
//create a message object
WXMediaMessage *message = [WXMediaMessage message];
//set the thumbnail image. This MUST be less than 32kb, or sendReq may return NO.
//we'll just use the full image resized to 100x100 pixels for now
[message setThumbImage:[image resizedImage:CGSizeMake(100,100) interpolationQuality:kCGInterpolationDefault]];
//create an image object and set the image data as a JPG representation of our UIImage
WXImageObject *ext = [WXImageObject object];
ext.imageData = UIImageJPEGRepresentation(image, 0.8);
message.mediaObject = ext;
//create a request
SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];
//this is a multimedia message, not a text message
req.bText = NO;
//set the message
req.message = message;
//set the "scene", WXSceneTimeline is for "moments". WXSceneSession allows the user to send a message to friends
req.scene = WXSceneTimeline;
//try to send the request
if (![WXApi sendReq:req]) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:#"Error" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}
}
