In iOS development, uibutton allows you to set text switching when both the image text and the departure button are set.

When using UIBUtton, we sometimes need to set pictures and text at the same time. The following code is for reference only:

UIButton * _ backButton = [UIButton
ButtonWithType: UIButtonTypeCustom];

[_ BackButton setFrame: CGRectMake (12,
8, 64, 28)];

[_ BackButton setTitle: @ "return"
ForState: UIControlStateNormal]; // sets the font of the button when it is not selected.

_ BackButton. titleLabel. font = [UIFont
SystemFontOfSize: 14.0f]; // set the font size of the button.

[_ BackButton setBackgroundImage: [UIImage
ImageNamed: @ "backButton.png"]
ForState: UIControlStateNormal]; // sets the button background to display the image.

[Self. view addSubview: _ backButton];

In the event of the above operation accident, we can also set the button to display different text and images in the selected (pressed) and normal (not selected) status,

UIButton * _ backButton = [UIButton
ButtonWithType: UIButtonTypeCustom];

[_ BackButton setFrame: CGRectMake (12,
8, 64, 28)];

[_ BackButton setTitle: @ "return"
ForState: UIControlStateNormal];

[_ BackButton setTitle: @ "Down" forState: UIControlStateHighlighted];

[_ BackButton setBackgroundColor: [UIColor clearColor];

[_ BackButton setTitleColor: [UIColor whiteColor] forState: UIControlStateNormal];

_ BackButton. titleLabel. font = [UIFont
SystemFontOfSize: 14.0f];

[_ BackButton setBackgroundImage: [UIImage
ImageNamed: @ "backButton.png"]
ForState: UIControlStateNormal];

[_ BackButton setBackgroundImage: [UIImage imageNamed: @ "DownButton.png"] forState: UIControlStateNormal];

[_ ToolBar addSubview: _ backButton];
