Fetching data from `plist` - ios

Question

I am using for in loop to fetch data from plist. But it is showing following exception:
2015-07-16 11:16:43.597 plistNeha[640:60b] -[__NSCFDictionary objectAtIndexedSubscript:]: unrecognized selector sent to instance 0x8d671b0

Code:
NSString *path=[[NSBundle mainBundle]pathForResource:#"x" ofType:#"plist"];
ald=[[NSDictionary alloc]initWithContentsOfFile:path];
for(NSDictionary *awq in ald){
NSLog(#"check");
NSString *qqw=#"";
qqw=[awq objectForKey:#"qq"];
NSLog(#"%#",qqw);
}
But, if I am fetching data one by one then it is showing on debugger area. for in loop is also working as it is printing check. May be the line after NSLog(#"check"); is creating some exceptions.

Answer 1

Try this
NSString *path=[[NSBundle mainBundle]pathForResource:#"x" ofType:#"plist"];
NSDictionary *ald=[[NSDictionary alloc]initWithContentsOfFile:path];
for(NSDictionary *awq in [ald allValues]){
NSLog(#"check");
NSString *qqw=#"";
qqw=[awq objectForKey:#"qq"];
NSLog(#"%#",qqw);
}

Answer 2

for in on a dictionary is enumerating its keys, not values. See this question for each loop in objective c for accessing NSMutable dictionary

Answer 3

Try this:
NSString *path=[[NSBundle mainBundle]pathForResource:#"x" ofType:#"plist"];
NSDictionary *plistDictionary = [[NSDictionary alloc]initWithContentsOfFile:path];
for(NSString *key in plistDictionary){
NSDictionary *dictionary = [plistDictionary objectForKey:key];
NSLog(#"%#",[dictionary objectForKey:#"qq"]);
}
I had to change your variable names because it was too confusing to work with 'ald', 'awq', 'qqw' , etc.
