You should use the class method

+ buttonWithType:

to create the button. After that, set the frame.

From the UIButton Class Reference:

buttonType

The button type. (read-only)

@property(nonatomic, readonly) UIButtonType buttonType

This means that you cannot change the buttonType once the button as been created.

For example, you can do

UIButton *test = [UIButton buttonWithType:UIButtonTypeCustom];
test.frame = CGRectMake(30, 30, 49, 49);
