plist文件

 

　　Plist文件

　　应用程序特定的plist文件可以被保存到app bundle的Resources文件夹。当应用程序运行起来的时候，就会去检查是不是有一个plist文件在用户的Documents文件夹下。假如没有的话，就会从app bundle目录下拷贝过来。

// Look in Documents for
NSArray *paths = NSSearchPathForDirectoriesInDomains(
    NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
myPlistPath = [documentsDirectory stringByAppendingPathComponent: 
"%@.plist", plistName] ];
[myPlistPath retain];
 
// If it's not there, copy it from the bundle
NSFileManager *fileManger = [NSFileManager defaultManager];
if
    NSString *pathToSettingsInBundle = [[NSBundle mainBundle] 
"plist"];
}        
 
　　现在我们就可以从Documents文件夹去读plist文件了。
NSArray *paths = NSSearchPathForDirectoriesInDomains(
    NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];
NSString *path = [documentsDirectoryPath 
"myApp.plist"];
NSMutableDictionary *plist = [NSDictionary dictionaryWithContentsOfFile: path];
 
　　Now read and set key/values
myKey = (int)[[plist valueForKey:@"myKey"] intValue];
myKey2 = (bool)[[plist valueForKey:@"myKey2"] boolValue];
 
[plist setValue:myKey forKey:@"myKey"];
[plist writeToFile:path atomically:YES];
