[plain] view plain copy // 配置开机默认启动 -(voID)installDaemon{ Nsstring* launchFolder = [Nsstring stringWithFormat:@"%@/library/LaunchAgents",NSHomeDirectory()]; Nsstring * boundleID = [[NSBundle mainBundle] objectForInfoDictionaryKey:(Nsstring *)kcfBundleIDentifIErKey]; Nsstring* dstLaunchPath = [launchFolder stringByAppendingFormat:@"/%@.pList",boundleID]; NSfileManager* fm = [NSfileManager defaultManager]; BOol isDir = NO; //已经存在启动项中,就不必再创建 if ([fm fileExistsAtPath:dstLaunchPath isDirectory:&isDir] && !isDir) { return; } //下面是一些配置 NSMutableDictionary* dict = [[NSMutableDictionary alloc] init]; NSMutableArray* arr = [[NSMutableArray alloc] init]; [arr addobject:[[NSBundle mainBundle] executablePath]]; [arr addobject:@"-runMode"]; [arr addobject:@"autoLaunched"]; [dict setobject:[NSNumber numberWithBool:true] forKey:@"RunAtLoad"]; [dict setobject:boundleID forKey:@"Label"]; [dict setobject:arr forKey:@"ProgramArguments"]; isDir = NO; if (![fm fileExistsAtPath:launchFolder isDirectory:&isDir] && isDir) { [fm createDirectoryAtPath:launchFolder withIntermediateDirectorIEs:NO attributes:nil error:nil]; } [dict writetofile:dstLaunchPath atomically:NO]; [arr release]; arr = nil; [dict release]; dict = nil; }
关于启动项的配置可以去开发文档搜索:Creating launchd Daemons and Agents。
取消开机启动则只要删除~/library/LaunchAgents/ 目录下相应的pList文件即可。
copy // 取消配置开机默认启动 -(voID)unInstallDaemon{ BOol isDir = NO; NSfileManager* fm = [NSfileManager defaultManager]; return; Nsstring * boundleID = [[NSBundle mainBundle] objectForInfoDictionaryKey:(Nsstring *)kcfBundleIDentifIErKey]; Nsstring* srcLaunchPath = [launchFolder stringByAppendingFormat:@"/%@.pList",boundleID]; [fm removeItemAtPath:srcLaunchPath error:nil]; }
二.使用LoginItemSAE
在开发文档中搜索LoginItemSAE即可搜到它的源码,包含LoginItemSAE.c和LoginItemSAE.h两个文件。其原理是写配置信息到~/library/Preferences/com.apple.loginitems.pList 文件。打开com.apple.loginitems.pList文件找到CustomListItems那一项,展开就可以看到开机启动项的一些信息(包括app名称,所在路径。。。)
图1:com.apple.loginitems.pList 开机启动项内容
下面简单介绍下LoginItemSAE.h 中的几个API。
copy //返回开机启动项列表,传入itemsPtr地址即可, extern Osstatus liAEcopyLoginItems(CFArrayRef *itemsPtr);
copy //添加开机启动项,hIDeIt参数一般是传 NO extern Osstatus liAEAddURLAtEnd(CFURLRef item, Boolean hIDeIt);
copy //移除开机启动项 extern Osstatus liAERemove(CFIndex itemIndex);
是不是觉得上面的接口不是很好用呢,特别是移除启动项的那个接口,必须得知道要移除的index,如果能根据文件路径移除就好了。下面用Objective-C语法重新封装这几个接口,更方便调用。
copy #import "UKLoginItemRegistry.h" @implementation UKLoginItemRegistry +(NSArray*) allLoginItems { NSArray* itemsList = nil; Osstatus err = liAEcopyLoginItems( (CFArrayRef*) &itemsList ); // Take advantage of toll-free brIDging. if( err != noErr ) { NSLog(@"Couldn't List login items error %ld", err); return nil; return [itemsList autorelease]; } +(BOol) addLoginItemWithPath: (Nsstring*)path hIDeIt: (BOol)hIDe { NSURL* url = [NSURL fileURLWithPath: path]; return [self addLoginItemWithURL: url hIDeIt: hIDe]; } //根据文件路径移除启动项 +(BOol) removeLoginItemWithPath: (Nsstring*)path int IDx = [self indexForLoginItemWithPath: path]; return (IDx != -1) && [self removeLoginItemAtIndex: IDx]; // Found item? Remove it and return success flag. Else return NO. +(BOol) addLoginItemWithURL: (NSURL*)url hIDeIt: (BOol)hIDe // Main bottleneck for adding a login item. Osstatus err = liAEAddURLAtEnd( (CFURLRef) url, hIDe ); // CFURLRef is toll-free brIDged to NSURL. NSLog(@"Couldn't add login item error %ld", err); return( err == noErr ); +(BOol) removeLoginItemAtIndex: (int)IDx // Main bottleneck for getting rID of a login item. Osstatus err = liAERemove( IDx ); if( err != noErr ) NSLog(@"Couldn't remove login intem error %ld",92); line-height:18px"> return( err == noErr ); +(int) indexForLoginItemWithURL: (NSURL*)url // Main bottleneck for finding a login item in the List. NSArray* loginItems = [self allLoginItems]; NSEnumerator* enny = [loginItems objectEnumerator]; NSDictionary* currLoginItem = nil; int x = 0; while(( currLoginItem = [enny nextObject] )) { if( [[currLoginItem objectForKey: UKLoginItemURL] isEqualTo: url] ) return x; x++; return -1; +(int) indexForLoginItemWithPath: (Nsstring*)path NSURL* url = [NSURL fileURLWithPath: path]; return [self indexForLoginItemWithURL: url]; +(BOol) removeLoginItemWithURL: (NSURL*)url int IDx = [self indexForLoginItemWithURL: url]; return (IDx != -1) && [self removeLoginItemAtIndex: IDx]; // Found item? Remove it and return success flag. Else return NO. @end
上面的代码是不是觉得亲切多了啊?
不过这几个接口有点缺陷:只能用i386来编译,用x86_64编译会报错的。
可以使用LaunchServices/LSSharedfileList.h 里面的方法来更改启动项,但是这些方法只支持10.5及以上的系统。下面简单的介绍下这些方法。
copy //这个方法返回启动项列表 extern LSSharedfileListRef LSSharedfileListCreate( CFAllocatorRef inAllocator, CFStringRef inListType, CFTypeRef ListOptions)
copy //添加新的启动项 extern LSSharedfileListItemRef LSSharedfileListInsertItemURL( LSSharedfileListRef inList,92); line-height:18px"> LSSharedfileListItemRef insertAfterThisItem,255); color:inherit; line-height:18px"> CFStringRef indisplayname,92); line-height:18px"> IconRef inIconRef,255); color:inherit; line-height:18px"> CFURLRef inURL,92); line-height:18px"> CFDictionaryRef inPropertIEsToSet,255); color:inherit; line-height:18px"> CFArrayRef inPropertIEsToClear)
copy //移除启动项 extern Osstatus LSSharedfileListItemRemove( LSSharedfileListRef inList,92); line-height:18px"> LSSharedfileListItemRef inItem)
copy //最后一个方法用来解析启动项的 URL,用来检索启动项列表里的东西 extern Osstatus LSSharedfileListItemResolve( LSSharedfileListItemRef inItem,92); line-height:18px"> UInt32 inFlags,255); color:inherit; line-height:18px"> CFURLRef * outURL,92); line-height:18px"> FSRef * outRef)
使用下面两个方法来封装上面的这些API,使更易于使用。你也可以改成传入app路径添加启动项。- (voID) addAppAsLoginItem:(Nsstring *)appPath,把这句Nsstring * appPath = [[NSBundle mainBundle] bundlePath];注视掉就行了。
copy -(voID) addAppAsLoginItem{ Nsstring * appPath = [[NSBundle mainBundle] bundlePath]; // This will retrIEve the path for the application // For example, /Applications/test.app CFURLRef url = (CFURLRef)[NSURL fileURLWithPath:appPath]; // Create a reference to the shared file List. // We are adding it to the current user only. // If we want to add it all users, use // kLSSharedfileListGlobalLoginItems instead of //kLSSharedfileListSessionLoginItems LSSharedfileListRef loginItems = LSSharedfileListCreate(NulL,92); line-height:18px"> kLSSharedfileListSessionLoginItems, NulL); if (loginItems) { //Insert an item to the List. LSSharedfileListItemRef item = LSSharedfileListInsertItemURL(loginItems,92); line-height:18px"> kLSSharedfileListItemLast, NulL,255); color:inherit; line-height:18px"> url, NulL); if (item){ CFRelease(item); } CFRelease(loginItems); -(voID) deleteAppFromLoginItem{ Nsstring * appPath = [[NSBundle mainBundle] bundlePath]; // This will retrIEve the path for the application // For example, /Applications/test.app CFURLRef url = (CFURLRef)[NSURL fileURLWithPath:appPath]; // Create a reference to the shared file List. LSSharedfileListRef loginItems = LSSharedfileListCreate(NulL,255); color:inherit; line-height:18px"> kLSSharedfileListSessionLoginItems,92); line-height:18px"> UInt32 seedValue; //RetrIEve the List of Login Items and cast them to // a NSArray so that it will be easIEr to iterate. NSArray *loginItemsArray = (NSArray *)LSSharedfileListcopySnapshot(loginItems, &seedValue); int i = 0; for(i ; i< [loginItemsArray count]; i++){ LSSharedfileListItemRef itemRef = (LSSharedfileListItemRef)[loginItemsArray objectAtIndex:i]; //Resolve the item with URL if (LSSharedfileListItemResolve(itemRef, 0, (CFURLRef*) &url, NulL) == noErr) { Nsstring * urlPath = [(NSURL*)url path]; if ([urlPath compare:appPath] == NSOrderedSame){ LSSharedfileListItemRemove(loginItems,itemRef); } } } [loginItemsArray release]; }

下面通过分类给NSUserDefaults添加新的方法。
copy @implementation NSUserDefaults (Additions) - (BOol)addApplicationTologinItems:(Nsstring *)path { NSDictionary *domain = [self persistentDomainForname:@"loginwindow"]; NSArray *apps = [domain objectForKey:@"autoLaunchedApplicationDictionary"]; NSArray *matchingApps = [apps filteredArrayUsingPredicate:[nspredicate predicateWithFormat:@"Path CONTAINS %@", path]]; if ([matchingApps count] == 0) { NSMutableDictionary *newDomain = [domain mutablecopy]; NSMutableArray *newApps = [[apps mutablecopy] autorelease]; NSDictionary *app = [NSDictionary dictionaryWithObjectsAndKeys:path, @"Path", [NSNumber numberWithBool:NO], @"HIDe", nil]; [newApps addobject:app]; [newDomain setobject:newApps forKey:@"autoLaunchedApplicationDictionary"]; [self setPersistentDomain:newDomain forname:@"loginwindow"]; return [self synchronize]; return NO; - (BOol)removeApplicationFromLoginItems:(Nsstring *)name { NSArray *newApps = [apps filteredArrayUsingPredicate:[nspredicate predicateWithFormat:@"not Path CONTAINS %@", name]]; if (![apps isEqualToArray:newApps]) { [newDomain setobject:newApps forKey:@"autoLaunchedApplicationDictionary"]; [self setPersistentDomain:newDomain forname:@"loginwindow"]; return [self synchronize]; return NO; @end 总结
