Yes, I want to add a UITextView (and other like IUView, IUImage...) when pressing a button, and
I want to resize, move, change color...
Like a power point, for now I just want to insert a UITextView.
I gather that English is not your native language? You might want to get some help from a fluent English speaker, as your first couple of posts are just about unreadable.
You need to write code that creates multiple text fields at different locations, sets them to contain different text, and then adds them to your view controller's content view.
How you do that specifically will depend on what you want to do.
You could allocate a grid space on your app screen for these fields, and then write code that loops through the rows and columns, adding a text field at each location in the grid.
You asked "How do I for set diferent names?" What different names? How will you generate these different names? Looping?
