[ iOS中 iOS10.3如何更换 app 图标 (教程)](http://blog.csdn.net/qq_31810357/article/details/68489138
)
### iOS中 iOS10.3如何更换 app 图标 利用runtime后台切换icon
#### 效果如下：
#### info.plist 如何填写呢？一时可能搞不清楚如何操作，下面做个实例:
```
CFBundleIcons
CFBundleAlternateIcons
newIcon
CFBundleIconFiles
newIcon
UIPrerenderedIcon
CFBundlePrimaryIcon
CFBundleIconFiles
Icon60X60
```
#### 替换图标部分的代码：
```
- (void)changeAppIcon
{
if ([UIApplication sharedApplication].supportsAlternateIcons) {
NSLog(@"you can change this app's icon");
}else{
NSLog(@"you can not change this app's icon");
return;
}
NSString *iconName = [[UIApplication sharedApplication] alternateIconName];
if (iconName) {
// change to primary icon
[[UIApplication sharedApplication] setAlternateIconName:nil completionHandler:^(NSError * _Nullable error) {
if (error) {
NSLog(@"set icon error: %@",error);
}
NSLog(@"The alternate icon's name is %@",iconName);
}];
}else{
// change to alterante icon
[[UIApplication sharedApplication] setAlternateIconName:@"newIcon" completionHandler:^(NSError * _Nullable error) {
if (error) {
NSLog(@"set icon error: %@",error);
}
NSLog(@"The alternate icon's name is %@",iconName);
}];
}
}
```
### 遇到一个问题：必须弹框吗？
#### A：NO！
#### 优化：利用runtime后台切换icon
```
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self runtimeReplaceAlert];
}
// 利用runtime来替换展现弹出框的方法
- (void)runtimeReplaceAlert
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
Method presentM = class_getInstanceMethod(self.class, @selector(presentViewController:animated:completion:));
Method presentSwizzlingM = class_getInstanceMethod(self.class, @selector(ox_presentViewController:animated:completion:));
// 交换方法实现
method_exchangeImplementations(presentM, presentSwizzlingM);
});
}
// 自己的替换展示弹出框的方法
- (void)ox_presentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion {
if ([viewControllerToPresent isKindOfClass:[UIAlertController class]]) {
NSLog(@"title : %@",((UIAlertController *)viewControllerToPresent).title);
NSLog(@"message : %@",((UIAlertController *)viewControllerToPresent).message);
// 换图标时的提示框的title和message都是nil，由此可特殊处理
UIAlertController *alertController = (UIAlertController *)viewControllerToPresent;
if (alertController.title == nil && alertController.message == nil) { // 是换图标的提示
return;
} else {// 其他提示还是正常处理
[self ox_presentViewController:viewControllerToPresent animated:flag completion:completion];
return;
}
}
[self ox_presentViewController:viewControllerToPresent animated:flag completion:completion];
}
```
