使用场景： 可以快速高效的遍历数组和字典。
创建一个model类：RACSequenceModel
创建数据模型：
NSString *path = [[NSBundle mainBundle] pathForResource:@"flags.plist" ofType:nil];
NSArray *dictArr = [NSArray arrayWithContentsOfFile:path];
//之所以在这打印主线程后面会用到。
NSLog(@"*****%@",[NSThread mainThread]);
[self.dataarr removeAllObjects];
for(NSDictionary*dicindictArr) {
RACSequenceModel*model = [RACSequenceModel new];
model.name= dic[@"name"];
model.icom= dic[@"icon"];
[self.dataarraddObject:model];
}
对数组进行遍历：
@weakify(self);
[self.dataarr.rac_sequence.signal subscribeNext:^(id _Nullable x) {
@strongify(self);
NSLog(@"%@",x);
//异步遍历
