如何添加图标到iphone / ipod状态栏？ [英] How to add an icon into iphone/ipod status bar?

问题描述

Apple不允许开发人员在状态栏中添加图标吗？

Does Apple not allow developers to add an icon into a status bar?

我按照书中的代码。代码很简单：

I followed code from a book. The code is simple:

@interface UIApplication (extended) 
- (void) addStatusBarImageNamed:(NSString *)aName; 
- (void) removeStatusBarImageNamed:(NSString *)aName; 

@end 

- (void)performAction{
    if (xxx) {
        [[UIApplication sharedApplication]addStatusBarImageNamed:@"Default_EN.png"];
    }
    else {
        [[UIApplication sharedApplication]addStatusBarImageNamed:@"Default_EC.png"];

    }
}

但它给出以下反馈：

-addStatusBarImageNamed：已弃用。不做任何事。

-addStatusBarImageNamed: is deprecated. Doing nothing.

我能做什么？

推荐答案

在类/ YourViewController.m 中， addStatusBarImageNamed：removeOnExit：方法需要被覆盖。

In Classes/YourViewController.m, the addStatusBarImageNamed:removeOnExit: method needs to be overwritten with this.

- (void) addStatusBarImageNamed:(NSString*)image removeOnExit: (BOOL) remove {
if(_statusbarimage!=nil && _responds) {
if ([[[NSUserDefaults standardUserDefaults] objectForKey:@"statusBarEnabled"] integerValue] == 1)
[self removeStatusBarImageNamed:_statusbarimage];
statusbarimage=image;
}
if (_responds) {
if ([[[NSUserDefaults standardUserDefaults] objectForKey:@"statusBarEnabled"] integerValue] == 1)
[super addStatusBarImageNamed:image removeOnExit: remove];
}
}  

看看是否正常。
