Answer 1

The problem is that you are setting _bt3.titleLabel.text directly. Don't do that.

A button has states: normal, highlighted, selected, and disabled. It knows what its text should be for each state. When _bt3 changes state, it sets _bt3.titleLabel.text. This overrides your change to _bt3.titleLabel.text.

If you don't set the text for a non-normal state, the button uses the text for the normal state.

When the user touches _bt3, _bt3 changes its state to highlighted and sets _bt3.titleLabel.text to the text set for its highlighted state. When the user stops touching _bt3, _bt3 changes its state back to normal and sets _bt3.titleLabel.text to the text set for its normal state.

So instead of setting _bt3.titleLabel.text directly, you need to tell the button what text it should display in the normal state:

[_bt3 setTitle:@"Bar" forState:UIControlStateNormal];
