我们可以对UITextView采取哪些addTarget操作？

Question

我想在UITextView上使用addTarget:action,如on(UITextField或UIButton).

我想在UITextView上调用一个方法.

请给出一些可能的解决方案

谢谢...

UITextView  *TXT_First_Tag = [[UITextView alloc] initWithFrame:CGRectMake(5, textPosY, 350, 65)];
TXT_First_Tag.backgroundColor = [UIColor whiteColor];
TXT_First_Tag.font = [UIFont fontWithName:@"Arial-BoldMT" size:30.0];
TXT_First_Tag.editable =YES;
TXT_First_Tag.tag = i; 
TXT_First_Tag.textColor = [UIColor blackColor];


[TXT_First_Tag addTarget:self action:@selector(C6Loop) forControlEvents:UIControlEventEditingDidEnd]; //  This Line I want to use, it's working fine on textfield...
[scrollview addSubview:TXT_First_Tag];

为此,我们使用UITextView委托方法.

把它放在你的代码中.

UITextView  *TXT_First_Tag = [[UITextView alloc] initWithFrame:CGRectMake(5, textPosY, 350, 65)];
TXT_First_Tag.backgroundColor = [UIColor whiteColor];
TXT_First_Tag.font = [UIFont fontWithName:@"Arial-BoldMT" size:30.0];
TXT_First_Tag.editable =YES;
TXT_First_Tag.delegate  =   self;
TXT_First_Tag.tag = i; 
TXT_First_Tag.textColor = [UIColor blackColor];
[scrollview addSubview:TXT_First_Tag];

- (void)textViewDidBeginEditing:(UITextView *)textView{
    NSLog(@"Begin editing");
}

- (void)textViewDidEndEditing:(UITextView *)textView{
    NSLog(@"DidEndEditing");
}

- (BOOL)textViewShouldBeginEditing:(UITextView *)textView{
    NSLog(@"ShouldBeginEditing");
    return TRUE;
}

- (BOOL)textViewShouldEndEditing:(UITextView *)textView{
    NSLog(@"ShouldEndEditing");
    return TRUE;
}
