Question

我尝试使用initWithContentsOfURL:

从其他plist文件加载plist文件

我解释说，我有一个表格视图使用我的主机中的plist文件，使用此metod：

NSMutableArray *genres = [[NSMutableArray alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://www.myurl.com/file.plist"]];
    self.loadGenres = genres;

当选择一个cel加载其他UITableView时，怎么能说到第二个表视图从第一个plist中使用<string>从url获取其他plist？

喜欢：

NSMutableArray *genres = [[NSMutableArray alloc] initWithContentsOfURL:[self.loadGenres objectForKey:@"PLIST URL"]];
self.loadGenres = genres;

感谢您的支持。

Answer 1

您不能在数组中使用键值编码。

相反尝试这样，

NSMutableDictionary * genres = [[NSMutableDictionary alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://www.myurl.com/file.plist"]];
self.loadGenres = genres; // your self.loadGenres must be Dictionary type

NSMutableDictionary * genres = [[NSMutableDictionary alloc] initWithContentsOfURL:[NSURL URLWithString:[[self.loadGenres objectForKey:@"PLIST URL"]stringValue]]];
self.loadGenres = genres;

尝试以下方法在YourClass.h中

NSURLConnection* linksConnection;
NSMutableData* linksData;

在YourClass.m

中

-(void) loadURL
{

NSMutableURLRequest* the_request = [NSMutableURLRequest requestWithURL:[NSURL        URLWithString:YOUR_URL]];
linksConnection = [[NSURLConnection alloc] initWithRequest:the_request delegate:self startImmediately:YES];

if(linksConnection != nil)
{
    linksData = [[NSMutableData data] retain];

}
}

-(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
 [linksData setLength:0];
}

-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[linksData appendData:data];
}

-(void) connectionDidFinishLoading:(NSURLConnection *)connection
{

NSString *errorStr = nil;
NSPropertyListFormat format;
NSDictionary *propertyList = [NSPropertyListSerialization propertyListFromData:linksData
                                                              mutabilityOption:NSPropertyListImmutable
                                                                        format:&format
                                                              errorDescription:&errorStr];
NSMutableArray*  myArray = [[propertyList objectForKey:@"sample"] retain];
}

我相信这会对你有很大的帮助
