Hide toolbar automatically

 

 

Before calling the pushviewcontroller method in uinavigationcontroller to the next screen, set the hidesbottombarwhenpushed attribute of the image to yes, and the toolbar will be hidden in the future. You can set the toolbarhidden attribute or call the settoolbarhidden: animated: Method to hide the toolbar. However, after you use the hidesbottombarwhenpushed attribute, the toolbar is automatically displayed when you return to the original screen again, the tool bar will be hidden in the above two methods.

 

The hidesbottombarwhenpushed attribute only determines whether to hide the toolbar when the screen jumps. After the screen jumps, if you set the toolbarhidden attribute of uinavigationcontroller to no, the program will also prioritize the later settings.
