NSString *plistPath = [DOCUMENTS stringByAppendingPathComponent:@"Сamera.plist"];
    if([[NSFileManager defaultManager] fileExistsAtPath:plistPath])
    {
        NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];

    }

2 个解决方案

#1

// Do this instead:

//这样做:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *plistPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Сamera.plist"];

#2

NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *docDirPath = [documentsDirectory stringByAppendingPathComponent:@"YourPlist.plist"];

NSFileManager *fileManager = [NSFileManager defaultManager];

if(![fileManager fileExistsAtPath: docDirPath]) {
    NSString *bundle = [[NSBundle mainBundle] pathForResource:@"YourPlist" ofType:@"plist"];

    [fileManager copyItemAtPath:bundle toPath:docDirPath error:&error];

    NSLog(@"plist is copied to Directory");
 }

Make sure your directory contains the plist file.

确保您的目录包含plist文件。
