Answer 1

利用以下代码使图像发挥作用。

int imageSize = 20; //REPLACE WITH YOUR IMAGE WIDTH

UIImage *barBackBtnImg = [[UIImage imageNamed:@"NavBackButton"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, imageSize, 0, 0)];

[[UIBarButtonItem appearance] setBackButtonBackgroundImage:barBackBtnImg 
                                                  forState:UIControlStateNormal 
                                                barMetrics:UIBarMetricsDefault];

你们可以利用可再生的电离层电离层电离层,以具体说明哪些标准不应延伸。如果你把你的形象传到那里,你就赢得了你们的形象。

You don t have to put it in the .m file btw. (You could use the appDelegate.m file) just make sure it get s called before the NavigationBar is drawn.

除非我没有一件事,否则你必须在法典中设立国际律师联合会,以删除或改变名称,因此,它只适用于你把该守则列入的观点控制者:

UIBarButtonItem *myBackButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"back_button.png"] style:UIBarButtonItemStyleBordered target:nil action:nil];
self.navigationItem.backBarButtonItem = myBackButton;
[myBackButton release];

你颁布的法典之所以如此,是因为它只规定了背景和文件确实表明:

取得良好成果图像必须具有可观的形象。

Answer 3

你们可以创造Button习俗,并把它作为避风港。或者,你可以获取关于后纽州面积的图象。

删除子公司的名称:<条码>本身,标题=“;,以考虑到WillDisappear方法,并在考虑到WillAppear方法时再次确定所有权。

希望这将解决你的问题。
