如何让label实时显示textfield的输入

Answer 1

iOS7我通UITextFielddelegate获取直接输textField.text慢拍
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
NSString *text = [textField.text stringByReplacingCharactersInRange:range withString:string];
return YES;
}
今发现iOS7输入文候识别拼音字符串文nihao我通获取
[textField addTarget:self action:@selector(textFieldEditChanged:) forControlEvents:UIControlEventEditingChanged];
添加输入改变
- (void)textFieldEditChanged:(UITextField *)textField
{
NSLog(@"textfield text %@",textField.text);
}
我获取UITextField前输入内容我通判断系统版本输入进行同操作避免重复工作
