有引數的block使用，包括宣告，實現，呼叫

@property (nonatomic, copy) void(^SuccessBlock)(CGFloat,CGFloat);

  [manager startLocateAndSuccessBlock:^(CGFloat latitude, CGFloat longitude) {
        NSString *funcStr = [NSString stringWithFormat:@"locationCall(%f, %f, %f)",
                             latitude,longitude,0.0];
        NSString *responseStr = [webview stringByEvaluatingJavaScriptFromString:funcStr];
    }];
 

  self.SuccessBlock(coordinate.latitude,coordinate.longitude);

- (void)startLocateAndSuccessBlock:(void(^)(CGFloat,CGFloat))success{

    self.SuccessBlock = success;
}
