###限制只能输入一定长度的字符
使用UITextFieldDelegate的方法实现
-(BOOL)textField:(UITextField*)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string;
{
//string指此时输入的那个字符 textField指此时正在输入的那个输入框 返回YES就是可以改变输入框的值
NSString * toBeString = [textField.text stringByReplacingCharactersInRange:range withString:string]; //得到输入框的内容
if (self.myTextField == textField) //判断是否是我们想要限定的那个输入框
{
if ([toBeString length] > 20) { //如果输入框内容大于20则弹出警告
UIAlertView *alert =[ [UIAlertView alloc] initWithTitle:@"警告" message:@"超过输入最大长度" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil];
[alert show];
return NO;
}
}
return YES;
}
