1 通过NSUserDefaults共享数据
保存数据
- (void)saveDataByNSUserDefaults{ NSUserDefaults *shared = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.xxx"]; [shared setObject:@"asdfasdf" forKey:@"widget"]; [shared synchronize];}
读取数据
- (NSString *)readDataFromNSUserDefaults{ NSUserDefaults *shared = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.xxx"]; NSString *value = [shared valueForKey:@"widget"]; return value;}
2 通过NSFileManager共享数据
保存数据
- (BOOL)saveDataByNSFileManager{ NSError *err = nil; NSURL *containerURL = [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:@"group.com.xxx"]; containerURL = [containerURL URLByAppendingPathComponent:@"Library/Caches/widget"]; NSString *value = @"asdfasdfasf"; BOOL result = [value writeToURL:containerURL atomically:YES encoding:NSUTF8StringEncoding error:&err]; if (!result) { NSLog(@"%@",err); } else { NSLog(@"save value:%@ success.",value); } return result;}
读取数据
- (NSString *)readDataByNSFileManager{ NSError *err = nil; NSURL *containerURL = [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:@"group.com.xxx"]; containerURL = [containerURL URLByAppendingPathComponent:@"Library/Caches/widget"]; NSString *value = [NSString stringWithContentsOfURL:containerURL encoding:NSUTF8StringEncoding error:&err]; return value;}
