iOS UITextField get real-time monitor input, Chinese Pinyin character input state pre-removal
Real-time monitoring textField input content is not difficult, difficult is when Chinese input, Chinese Pinyin will now go. There are a bunch of characters, but also continue to increase. . . .
Solution:
- (void)viewDidLoad {
[super viewDidLoad];
UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(100, 100, 100, 30)];
[self.view addSubview:textField];
[textField addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
}
- (void)textFieldDidChange:(UITextField *)textField{
if (textField.markedTextRange == nil) {
NSLog(@"text:%@", textField.text);
// code to be written, like in the inside
}
}
