Loadin網址的plist從plist中

Question

我嘗試使用加載其他plist文件plist文件中initWithContentsOfURL:

我解釋，我一直在使用我的主機plist文件中一個表視圖，此梅託德：

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

當選擇一個細胞加載其他UITableView，但如何可以說第二個表視圖從第一plist內使用<string>從URL獲得其他plist？

像：

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

謝謝支持。

Answer 1

您不能在Array中使用Key-Value編碼。

而是嘗試這樣，

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; 

Answer 2

嘗試YourClass.h以下

NSURLConnection* linksConnection; 
NSMutableData* linksData; 

在YourClass.m

-(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]; 
} 

我相信這將幫助你lot
