[英]Can not find plist file in documents directory? How to modify the plist programmatically?
I have an application in Xcode 4.2. 我在Xcode 4.2中有一个应用程序。
I have created plist file as my requirement. 我已经创建了plist文件作为我的要求。
I have found the data from Applications main bundle and got the data in to the array. 我找到了Applications main bundle中的数据,并将数据输入到数组中。
But As I want to modify the plist data at run time, I could not find it in Documents Directory 但是,由于我想在运行时修改plist数据,我在Documents Directory中找不到它
Actually I want to modify the plist programmatically. 其实我想以编程方式修改plist。 Though I am not using mainbundle.
虽然我没有使用mainbundle。
-(NSString *) saveFilePath::(NSString *)tagString
{
NSArray *arr = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *strPath = [[arr objectAtIndex:0] stringByAppendingPathComponent:tagString];
return strPath;
}
Could not retrive the plist file.(Path I am getting, but path with file not getting) 无法检索plist文件。(我得到的路径,但文件未获取的路径)
I also could not find physically the plist file in the iphone simulator/App/Documents folder? 我也找不到iphone模拟器/ App / Documents文件夹中的plist文件?
you need to copy plist from bundle to document directory first 您需要先将plist从bundle复制到文档目录
-(void) checkAndCreateSetting
{
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writableDBPath= [documentsDirectory stringByAppendingPathComponent:@"Settings.plist"];
success = [fileManager fileExistsAtPath:writableDBPath];
if (success) return;
// The writable database does not exist, so copy the default to the appropriate location.
NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Settings.plist"];
success = [fileManager copyItemAtPath:defaultDBPath toPath:writableDBPath error:&error];
if (!success) {
NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]);
}
}
