我想要做的就是为这个艺术家阵列做准备。如何检查这些艺术家作为一个数组或只是一个字符串。请帮帮我。

Answer 1

这将说明您的问题在_recievedData中获取数据rx，然后检查对象的类。

id object = [NSJSONSerialization
                 JSONObjectWithData:_recievedData
                 options:kNilOptions
                 error:&error];
if (error)
{
     NSLog(@"Error in rx data:%@",[error description]);
}
if([object isKindOfClass:[NSString class]] == YES)
{
     NSLog(@"String rx from server");
}
else if ([object isKindOfClass:[NSDictionary class]] == YES)
{
     NSLog(@"Dictionary rx from server");
}
else if ([object isKindOfClass:[NSArray class]] == YES)
{
     NSLog(@"Array rx from server");
}

Answer 2

这应该对你有帮助。

id object = [responseData objectForKey:@"artists"];

if ([object isMemberOfClass:[NSString class]]) {
    // do the stuff for NSString
}
else if ([object isMemberOfClass:[NSArray class]]) {
    // do the stuff for NSArray
}

如何检查对象是ios中的字符串或数组
