Jump button controls above, what does that mean?
I tried, the action will be the first to get the button to Mody.

Look directly under the painting by the code. . . .

UIBUTTON * BUTTON = [UIBUTTON ALLOC] Initwithframe () to set a fixed coordinate size
uitextfield * filed. . . . . Also set the coordinate size

Not to cover it. . .
