我創建一個數據結構手動使用以下:如何讀取的.plist文件中的數據結構到NSArray的
NSDictionary* league1 = [[NSDictionary alloc] initWithObjectsAndKeys: @"Barclays Premier League", @"name",
@"Premier League", @"shortname",
@"101", @"id", nil];
NSDictionary* league2 = [[NSDictionary alloc] initWithObjectsAndKeys: @"Coca-Cola Championship", @"name",
@"Championship", @"shortname",
@"102", @"id", nil];
NSDictionary* league3 = [[NSDictionary alloc] initWithObjectsAndKeys: @"Scottish Premier League", @"name",
@"SPL", @"shortname",
@"201", @"id", nil];
NSDictionary* league4 = [[NSDictionary alloc] initWithObjectsAndKeys: @"Champions League", @"name",
@"UCL", @"shortname",
@"501", @"id", nil];
contentArray = [[NSArray alloc] initWithObjects:
[[NSDictionary alloc] initWithObjectsAndKeys: @"English", @"category", [[NSArray alloc] initWithObjects: league1, league2, nil], @"leagues", nil],
[[NSDictionary alloc] initWithObjectsAndKeys: @"Scottish", @"category", [[NSArray alloc] initWithObjects: league3, nil], @"leagues", nil],
[[NSDictionary alloc] initWithObjectsAndKeys: @"Tournaments", @"category", [[NSArray alloc] initWithObjects: league4, nil], @"leagues", nil],
nil];
[league1 release];
[league2 release];
[league3 release];
[league4 release];
不過,我認爲這將是更好的,如果它是從文件中讀取。所以,我創建了具有以下結構的文件leagues.plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<dict>
<key>category</key>
<string>English</string>
<key>leagues</key>
<array>
<dict>
<key>name</key>
<string>Barclays Premier League</string>
<key>shortname</key>
<string>Premier League</string>
<key>id</key>
<string>101</string>
</dict>
<dict>
<key>name</key>
<string>Coca-Cola Championship</string>
<key>shortname</key>
<string>Championship</string>
<key>id</key>
<string>102</string>
</dict>
</array>
</dict>
<dict>
<key>category</key>
<string>Scottish</string>
<key>leagues</key>
<array>
<dict>
<key>name</key>
<string>Scottish Premier League</string>
<key>shortname</key>
<string>SPL</string>
<key>id</key>
<string>201</string>
</dict>
</array>
</dict>
<dict>
<key>category</key>
<string>Tournaments</string>
<key>leagues</key>
<array>
<dict>
<key>name</key>
<string>Champions League</string>
<key>shortname</key>
<string>UCL</string>
<key>id</key>
<string>501</string>
</dict>
</array>
</dict>
</array>
</plist>
如何讀取我已經嘗試了各種方法,但沒有奏效這一文件。我甚至不知道我是否在正確的位置查找文件。作爲參考,我嘗試以下方法:
NSString* errorDesc = nil;
NSPropertyListFormat format;
NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"league" ofType:@"plist"];
NSData* plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];
contentArray = (NSArray*)[NSPropertyListSerialization
propertyListFromData:plistXML
mutabilityOption:NSPropertyListMutableContainersAndLeaves
format:&format
errorDescription:&errorDesc];
if (!contentArray) {
NSLog(errorDesc);
[errorDesc release];
}
或
NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"league" ofType:@"plist"];
contentArray = [NSArray arrayWithContentsOfFile:plistPath];
或
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *fooPath = [documentsPath stringByAppendingPathComponent:@"leagues.plist"];
NSLog(fooPath);
contentArray = [NSArray arrayWithContentsOfFile:fooPath];
NSLog(@"%@",contentArray);
這終於讓我徹底瘋了。請幫助!
太感謝您了
剛學在這裏:)。我不知道它是否在主包中。謝謝,我會檢查下。 – Xetius 2009-04-15 06:47:34
這是:[[NSDictionary dictionaryWithContentsOfFile:plistPath];' – shebelaw 2014-09-04 16:45:24
謝謝@shebelaw,我調整了代碼。認爲這是一個數組... – 2014-09-04 20:04:06
