Question

我使用以下代码将plist显示到NSDictionary / NSMutableDictionary中，但是当我打印该变量时它返回null值？请帮帮我？

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *Path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Recent.plist"];
NSLog(@"%@",Path); //Path is correct

NSDictionary *d=[[NSDictionary alloc]initWithContentsOfFile:Path];
NSMutableDictionary *data = [[NSMutableDictionary alloc]initWithContentsOfFile:Path];
NSLog(@"%@",d);

Buddy，您的代码是正确的，但请确保您的plist根是数组或字典

我认为它应该是你的情况下的数组

请尝试此代码，我只需将NSMutableDictionary更改为代码中的NSMutableArray

  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *Path = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Recent.plist"];
NSLog(@"%@",Path);


NSMutableArray *d = [[NSMutableArray alloc]initWithContentsOfFile:Path];

必须工作

无法将Plist值检索到NSDictionary
