Question

I am developing an application in which I have to set image as the iPhone wallpaper (the background image on the "slide to unlock" screen). Do we have any API reference for this. Please help

Answer 1

目前，您唯一能做的就是将图像保存到相机胶卷中，并向用户提供有关如何使用新图像更改墙纸的说明。

Answer 2

 NSString *str_mainMenu = [[NSBundle mainBundle] pathForResource:@"Unlock" ofType:@"jpg"];
    mainView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageWithContentsOfFile:str_mainMenu]];
