自定义写UIbutton和uitextfield时rect type

As pheelicks said for UIButton can create it with type UIButtonTypeCustom.

For UITextField set its border style to UITextBorderStyleNone.

    UIButton* button=[UIButtonbuttonWithType:UIButtonTypeRoundedRect];

UITextField* text1=[[UITextFieldalloc] initWithFrame:CGRectMake(120,10, 200, 30)];

    text1.borderStyle=UITextBorderStyleRoundedRect;
