How to Insert the UITextView into UIAlertview in iOS

问题

Also, I would like this UITextView with the text file in XXX.txt.It works fine in iOS6, but content does not appear on the UIAlertview in iOS7. my code is given as below:-

UITextView *tosTextView = [[UITextView alloc]initWithFrame:CGRectMake(12, 48, 260, 140)];

NSString *path = [[NSBundle mainBundle] pathForResource:@"TJTermsof Service"
                                                 ofType:@"txt"];
NSString *content = [NSString stringWithContentsOfFile:path
                                              encoding:NSUTF8StringEncoding
                                                 error:NULL];
[tosTextView setText:content];

tosTextView.textColor=[UIColor blackColor];
tosTextView.font = [UIFont fontWithName:@"LuzSans-Book" size:17];
tosTextView.editable = NO;
customAlert = [[UIAlertView alloc]initWithTitle:@" TOS \n\n\n\n\n\n " message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"I Agree",nil];



[customAlert addSubview:tosTextView];

[customAlert show];

This should work. Give it a shot. But it's a hack and might not be appreciated by Apple.

UIAlertView *testAlert = [[UIAlertView alloc] initWithTitle:title
                                                    message:@""
                                                   delegate:self
                                          cancelButtonTitle:@"Cancel"
                                          otherButtonTitles:@"Done", nil];
UITextView *textView = [UITextView new];
if (SYSTEM_VERSION_LESS_THAN(@"7.0"))//For Backward compatibility 
{
    [testAlert addSubview: textView];
}
else
{
    [testAlert setValue: textView forKey:@"accessoryView"];
}
[testAlert show];

You cannot modify the alert view view hierarchy in iOS7.

You need to either roll your own implementation of an alert view, or use an open source implementation, such as SDCAlertView.

I have tested this myself.

By default UIAlertview content is a textview. How large you are giving the content UIAlertview will definetly present it in a textview.

I think you have given the text in Alertview title. You should have given it in the message.
