此问题可能是由于API返回的数据类型与所需数据类型不匹配所致。建议将API返回的数据转换为需要的类型，并使用Angular的ChangeDetectorRef来强制更新视图。

以下是代码示例：

import { Component, OnInit, ChangeDetectorRef } from '@angular/core';
import { ApiService } from './api.service';

@Component({
  selector: 'app-data',
  template: `
    
{{ data }}
    
{{ loading }}
  `
})
export class DataComponent implements OnInit {
  data: any;
  loading: boolean;

  constructor(private apiService: ApiService, private cdRef: ChangeDetectorRef) {}

  ngOnInit() {
    this.loading = true;
    this.apiService.getData().subscribe((response) => {
      // Convert response data to required type
      this.data = response.map(item => item.name);

      // Trigger change detection to update view
      this.cdRef.detectChanges();

      this.loading = false;
    });
  }
}
