Answer 1

.h 文件中只有一个 int 变量，如下所示..

int AddNote;

在 viewDidLoad: 方法中分配 0 之后，例如..

AddNote = 0;

然后在下面的方法中创建它..

-(IBAction)btnAddTextView:(id)sender
{

    UITextView *txtAddNote=[[UITextView alloc]initWithFrame:CGRectMake(AddNote * 180,20, 180, 44)];
    [txtAddNote setBackgroundColor:[UIColor scrollViewTexturedBackgroundColor]];
    [txtAddNote setFont:[UIFont fontWithName:@"Helvetica-Bold" size:15]];
    txtAddNote.layer.borderWidth = 2.0;
    txtAddNote.layer.borderColor= [UIColor redColor].CGColor;
    AddNote++;

    txtAddNote.tag = AddNote;
    txtAddNote.userInteractionEnabled= YES;
    txtAddNote.delegate = self;
    txtAddNote.textColor = [UIColor whiteColor];
    //    [txtAddNote sizeToFit];
    //    [txtAddNote setClipsToBounds:YES];
    //    [viewTxt setClipsToBounds:YES];
    [self.view addSubview:txtAddNote];

    [txtAddNote release];
}

希望这对您有帮助...
