如何将字典数组保存到plist？

Question

Plist只是不保存自己...

我不明白我在这里做错了什么。请帮忙。

NSString *factorsFile = [[NSBundle mainBundle]pathForResource:@"factors" ofType:@"plist"];
NSMutableArray *factorsArray = [NSMutableArray arrayWithContentsOfFile:factorsFile];

NSMutableDictionary *dictFactor = [NSMutableDictionary dictionary];
[dictFactor setObject:self.nameField.text forKey:@"Factor"];
[dictFactor setObject:self.rankField.text forKey:@"Rank"];

NSLog(@"%@",dictFactor);

[factorsArray addObject:dictFactor];

NSLog(@"%@",factorsArray);

if([factorsArray writeToFile:factorsFile atomically:YES]){
    NSLog(@"lalal");
}

此代码能够进入最后一个if循环但是plist保持不变......为什么？

因为您无法在应用包中编写/修改文件。

您可以为表达式"ios plist write to bundle unchanged"执行Google搜索，然后您可以查看前四个结果。它们都是相同/重复的StackOverflow问题：

plist writing data inside dictionary

write into plist file using NSDictionary object

Not Able to write Boolean in plist file

writeToFile fails on iphone but works on simulator
