Answer 1

You can access data from plist in dictionary format thenceforth serialize it to get json string.
NSString *path = [[NSBundle mainBundle] pathForResource:#"yourPlistName" ofType:#"plist"];
NSData* data = [NSData dataWithContentsOfFile:path];
NSDictionary* dict= [NSPropertyListSerialization propertyListFromData:data
mutabilityOption:NSPropertyListImmutable
format:NSPropertyListXMLFormat_v1_0
errorDescription:NULL];
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict
options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonStr = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
-----SWIFT 3-----
if let url = Bundle.main.url(forResource:"yourPlistName", withExtension: "plist") {
do {
let data = try Data(contentsOf:url)
let dict = try PropertyListSerialization.propertyList(from: data, options: [], format: nil) as! [String:Any]
let jsonData = try JSONSerialization.data(withJSONObject: dict , options: .prettyPrinted)
// jsondata your required data
} catch {
print(error)
}
}

Answer 2

You can do that with this code:
NSMutableDictionary *plistDic = [[NSMutableDictionary alloc] initWithContentsOfFile: path];

Answer 3

Use the code below
NSString * plistPath = #“data.plist”;
NSMutableDictionary *plistData = [[NSMutableDictionary alloc] initWithContentsOfFile: plistPath];
NSError * err;
NSString * jsonStr = nil;
NSData * jsonData = [NSJSONSerialization dataWithJSONObject:plistData options:0 error:&err];
jsonStr = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

Answer 4

My plist was an NSArray, not an NSDictionary, so I had to do this:
NSString *plistPath = [[NSBundle mainBundle] pathForResource:#"myPlist" ofType:#"plist"];
NSArray *menuArray = [[NSArray alloc] initWithContentsOfFile:plistPath];
NSError *err;
NSString *jsonStr = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:menuArray options:0 error:&err];
jsonStr = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
