使用的plist字典应用程序设置 [英] Use a Plist dictionary for App settings

问题描述

我希望能够使用的plist的设置即时通讯在我的应用程序实施。我想要一本字典设置握住我的阵列，如调试，选项1，选项2下阵设置字典等我怎么会进入调试？

 的NSArray *路径= NSSearchPathForDirectoriesInDomains（NSDocumentDirectory，NSUserDomainMask，YES）;
的NSString * documentsDirectory = [路径objectAtIndex：0];
* NSString的myPlistPath = [documentsDirectory stringByAppendingPathComponent：@ProfileManager.plist];
*的NSDictionary = plistDict [[NSDictionary的页头] initWithContentsOfFile：myPlistPath];swDebug.on = [plistDict objectForKey：@调试];

解决方案

在您的例子调试是一个字符串，而不是一个数组（这是你仿佛说，这是在问题）。在这两种情况下，问题是，你正在访问错误的字典的关键。您有：

  swDebug.on = [plistDict objectForKey：@调试];
 

您需要：

  swDebug.on = [[plistDict objectForKey：@设置] objectForKey：@调试];
 

由于设置是字典的plist内的字典。

I want to be able to use a plist for settings Im implementing in my app. I want a dictionary "Settings" to hold my arrays, such as "Debug", "Option 1", Option 2", etc. How would I access "Debug"array under the "Settings" dictionary?

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *myPlistPath = [documentsDirectory stringByAppendingPathComponent:@"ProfileManager.plist"]; 
NSDictionary *plistDict = [[NSDictionary alloc] initWithContentsOfFile:myPlistPath]; 

swDebug.on = [plistDict objectForKey:@"Debug"];

.plist

解决方案

In your example Debug is a string, not an array (which is what you seem to say it is in the question). In either event, the issue is that you are accessing the key in the wrong dict. You have:

swDebug.on = [plistDict objectForKey:@"Debug"];

You would need:

swDebug.on = [[plistDict objectForKey:@"Settings"] objectForKey:@"Debug"];

Since settings is a dictionary within the dictionary plist.
