does anyone know how to allow only 140 characters in uitext view. Please help me guys.
thanks

i have got the solution for this problem. i did this to handle this and it is working fine
- (BOOL)textView
UITextView *)textView shouldChangeTextInRange
NSRange)range replacementText
NSString *)text
{
BOOL flag = NO;
NSLog(@"the text is %@",text);
NSLog(@"the length is %i",[text length]);
if([text length] == 0)
{
if([textView.text length] != 0)
{
flag = YES;
NSString *Temp = charbutton.title;
int j = [Temp intValue];
j = j +1 ;
charbutton.title = [[NSString alloc] initWithFormat:@"%i",j];
return YES;
}
else {
return NO;
}
}
else if([[textView text] length] > 139)
{
return NO;
}
if(flag == NO)
{
charbutton.title = [[NSString alloc] initWithFormat:@"%i",139-[textView.text length]];
}
return YES;
}
limiting characters in uitextview
Linear Mode
