Question

这是例行练习。我在我当前的项目中已经做过很多次并且效果很好。我逐行复制了代码行，相同的初始化。我的 plist 数据进入字典，但在初始化时不会进入其各自的数组。我有一个名为 initArraysPlist

的方法

-(void)initArraysPlist{
NSString *path1 = [[NSBundle mainBundle] pathForResource:@"trainerProfile" ofType:@"plist"];
// Load the file content and read the data into arrays
NSDictionary *dict1 = [[NSDictionary alloc] initWithContentsOfFile:path1];

trainerNames = [dict1 objectForKey:@"Names"];
trainerIcons = [dict1 objectForKey:@"Icons"];
trainerFactSheet= [dict1 objectForKey:@"Fact Sheet"];
trainerFocus = [dict1 objectForKey:@"Focus"];
trainerContactInfo= [dict1 objectForKey:@"Contact Info"];

}

我已经这样做了几次，目前它在我的代码中有效。所有的值都是正确的。我检查了很多次。当

请试试这个代码，它可能对你有帮助

// Read plist from bundle and get Root Dictionary out of it

NSDictionary *dictRoot = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"]];

// Your dictionary contains an array of dictionary
// Now pull an Array out of it.

NSArray *arrayList = [NSArray arrayWithArray:[dictRoot objectForKey:@"catlist"]];

// Now a loop through Array to fetch single Item from catList which is Dictionary

[arrayList enumerateObjectsUsingBlock:^(id obj, NSUInteger index, BOOL *stop) {

    // Fetch Single Item
    // Here obj will return a dictionary

     NSLog(@"Category name : %@",[obj valueForKey:@"category_name"]);
     NSLog(@"Category id   : %@",[obj valueForKey:@"cid"]);
}];

请阅读每一行的评论。

  NSString *path1 = [[NSBundle mainBundle] pathForResource:@"trainerProfile" ofType:@"plist"]; // **check if your plist is actually added in Bundle.If its there move to second line , if not then add plist in bundle.**

   NSDictionary *dict1 = [[NSDictionary alloc]    initWithContentsOfFile:path1];// **if plist is added in bundle , then check if you are getting value for dict1 . If no then you might be making some mistake in plist structure.**

如有可能，请post您的 plist 以获得更多说明。
