我想從包含嵌套字典的plist文件中獲取一個字符串。這是plist中:從嵌套在plist文件中的NSDictionary中獲取字符串
<dict>
<key>DataPoints</key>
<array>
<dict>
<key>source</key>
<string>BloomBerg</string>
<key>date</key>
<date>2010-01-31T14:54:13Z</date>
<key>value</key>
<integer>1233</integer>
</dict>
<dict>
<key>source</key>
<string>BloomBerg</string>
<key>date</key>
<date>2010-02-02T14:54:13Z</date>
<key>value</key>
<integer>1235</integer>
</dict>
<dict>
<key>source</key>
<string>BloomBerg</string>
<key>date</key>
<date>2010-01-31T14:54:13Z</date>
<key>value</key>
<integer>1230</integer>
</dict>
</array>
</dict>
這裏是我的代碼:
NSString *path = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"sampledata.plist"];
NSDictionary* plotDictionary = [[NSDictionary dictionaryWithContentsOfFile:path] retain];
NSArray* plotData = [plotDictionary objectForKey:@"DataPoints"];
NSLog(@"Got the dict %d",[plotData count]);
NSDictionary* plotPoint = [plotData objectAtIndex:1];
NSLog(@"Got the point %d",[plotPoint count]);
NSString* source = [plotPoint objectForKey:@"source"];
NSLog(@"...", source);
我得到陣列的計數和類型的字典而不是字符串的值。大概做一些簡單的錯事...
Pfffff ...帶了我整個下午...抱歉,感謝您的幫助! – Nick 2010-01-31 17:21:07
