为什么不显示图像？

Question

我从plist文件加载注释，我还需要从plist文件读取图像的图像。

我尝试了以下代码，但它不起作用。

NSString *path = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"];
    NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:path];
    NSArray *anns = [dict objectForKey:@"Category1"];
    pinView.image = [UIImage imageNamed:[[dict objectForKey:anns] valueForKey:@"Icon"]];

我的plist结构：

Answer 1

这看起来不对：

NSArray *anns = [dict objectForKey:@"Category1"];
pinView.image = [UIImage imageNamed:[[dict objectForKey:anns] valueForKey:@"Icon"]];
                                                        ^^^^

anns是一个数组，所以它不能是你词典的关键。我的猜测是你想要这个：

NSArray *anns = [dict objectForKey:@"Category1"];
pinView.image = [UIImage imageNamed:[[anns objectAtIndex:0] objectForKey:@"Icon"]];
