iPhone開發(fā)基礎(chǔ)學(xué)習(xí) 在程序里設(shè)置Push是本文要介紹的內(nèi)容，最近做項(xiàng)目有一個(gè)需求，要在程序得系統(tǒng)設(shè)置里進(jìn)行push的設(shè)置。在網(wǎng)上搜了幾天資料沒找著啥。今天忽然心血來潮跟蹤系統(tǒng)注冊(cè)push時(shí)得代碼，居然發(fā)現(xiàn)有可行得解決方法，思路如下：

1、在iphone得framework里的UIApplication.h中有以下函數(shù)：

@interface UIApplication (UIRemoteNotifications)  
- (void)registerForRemoteNotificationTypes:(UIRemoteNotificationType)types __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);  
- (void)unregisterForRemoteNotifications __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);       
  // calls -registerForRemoteNotificationTypes with UIRemoteNotificationTypeNone  
 
// returns the enabled types, also taking into account any systemwide settings; doesn't relate to connectivity  
- (UIRemoteNotificationType)enabledRemoteNotificationTypes __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);  
@end 

2、首先可以用[[UIApplication sharedApplication] enabledRemoteNotificationTypes]獲取到允許得push推送類型。然后再調(diào)用registerForRemoteNotificationTypes進(jìn)行修改。若要關(guān)閉程序得push服務(wù)，可調(diào)用unregisterForRemoteNotifications.

3、補(bǔ)充：以上想法以實(shí)現(xiàn)。補(bǔ)充部分代碼。settingsData為tableview的數(shù)據(jù)源數(shù)組

a、獲取系push設(shè)置，用于顯示給用戶

//push設(shè)置  
 
NSMutableArray * pushOptions = [[NSMutableArray alloc] init];  
 
UIRemoteNotificationType notificationType = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];  
 
 
NSMutableDictionary * soundNotice = [[NSMutableDictionary alloc] initWithObjectsAndKeys:  
                                     @"聲音", @"name",  
                                     @"0",   @"status",  
                                     nil];  
if (notificationType & UIRemoteNotificationTypeSound) {  
    [soundNotice setValue:@"1" forKey:@"status"];  
}          
[pushOptions addObject:soundNotice];  
[soundNotice release];  
 
 
NSMutableDictionary * alertNotice = [[NSMutableDictionary alloc] initWithObjectsAndKeys:  
                                     @"提醒", @"name",  
                                     @"0",   @"status",  
                                     nil];  
if (notificationType & UIRemoteNotificationTypeAlert) {  
    [alertNotice setValue:@"1" forKey:@"status"];  
}          
[pushOptions addObject:alertNotice];  
[alertNotice release];  
 
 
NSMutableDictionary * badgeNotice = [[NSMutableDictionary alloc] initWithObjectsAndKeys:  
                                     @"標(biāo)記", @"name",  
                                     @"0",   @"status",  
                                     nil];  
if (notificationType & UIRemoteNotificationTypeBadge) {  
    [badgeNotice setValue:@"1" forKey:@"status"];  
}          
[pushOptions addObject:badgeNotice];  
[badgeNotice release];  
 
 
NSDictionary * pushConfig = [[NSDictionary alloc] initWithObjectsAndKeys:  
                              @"通知設(shè)置", @"groupName",  
                              pushOptions,    @"data",  
                              nil];  
[self.settingsData addObject:pushConfig];  
[pushOptions release];  
[pushConfig release]; 

b、獲取用戶設(shè)置的數(shù)據(jù)放入pushdata，然后向系統(tǒng)提交設(shè)置

NSArray * pushData = [[settingsData objectAtIndex:indexPath.section] objectForKey:@"data"];  
NSInteger length = [pushData count];  
 
UIRemoteNotificationType myType = 0;  
 
for (NSInteger i =0; i< length; i++) {  
    if ([[[pushData objectAtIndex:i] objectForKey:@"status"] intValue] ==1) {  
        switch (i) {  
            case 0:        myTypemyType = myType|UIRemoteNotificationTypeSound;    break;  
            case 1:        myTypemyType = myType|UIRemoteNotificationTypeAlert;    break;  
            case 2:        myTypemyType = myType|UIRemoteNotificationTypeBadge;    break;  
            default:    break;  
        }  
    }  
}  
 
if (myType != 0) {  
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myType];  
}else {  
    [[UIApplication sharedApplication] unregisterForRemoteNotifications];  
} 

希望以上思路對(duì)有這方面需求得人有幫助。以上方案我暫未用于代碼實(shí)現(xiàn)。若有問題。請(qǐng)留言共同商討。
