Question

如何检查plist是否为空？

Answer 1

如果你的 plist 是一个数组:

NSArray *array = [[NSArray alloc] initWithContentsOfFile:yourFile];
if ([array count] == 0) {
    NSLog(@"Your plist is empty");
}

或者如果您的 plist 是字典:

NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:yourFile];
if ([[dictionary allKeys] count] == 0) {
    NSLog(@"Your plist is empty");
}
