此方法只適用于iOS10.3
// Pass
nilto use the primary application icon. The completion handler will be invoked asynchronously on an arbitrary background queue; be sure to dispatch back to the main queue before doing any further UI work.
- (void)setAlternateIconName:(nullable NSString *)alternateIconName completionHandler:(nullable void (^)(NSError *_Nullable error))completionHandler NS_EXTENSION_UNAVAILABLE("Extensions may not have alternate icons") API_AVAILABLE(ios(10.3), tvos(10.2));

主要實現(xiàn)代碼
-(void)setIcon:(NSString *)iconName
{
//默認的icon些己，iconName =nil;
NSString *appiconName = [[UIApplication sharedApplication] alternateIconName];
NSLog(@"目前iconName %@",appiconName);
[[UIApplication sharedApplication]setAlternateIconName:iconName completionHandler:^(NSError * error){
NSLog(@"samli error %@",error);
}];
