Can we control the length of the text in UITextField

[vishal]

Hi,

I want to control the length of the text entered by user in a UITextField. Is there any way to do this?

iirc there is a function in the delegate called each time the text changes.
for each caracter decide if it should be added or not

Here is what I did... crude way I say, but works... This will clip the user input to 8 character. Assign this to editFinish event outlet.

-(IBAction)checkName {
	
	int msglen = [UserTextfield.text length];
	NSString *tmpstr;
	NSString *oklength;

	tmpstr = UserTextfield.text;
	oklength = @"";
	
	if (msglen>8) {

		unichar thechar;
		for (int index = 0; index < 8; index += 1)  
		{  
			thechar = [tmpstr characterAtIndex:index];
		    oklength = [NSString stringWithFormat:@"%@%C" , oklength,thechar];
		}
		
		UserTextfield.text = oklength;
	}
}

check the NSString class, it has a substring function
