在Plist中访问坐标-iOS [英] Accessing Coordinates in Plist - iOS

问题描述

而不是使用如下所示的硬编码访问特定纬度

Instead of accessing specific latitude with hardcoded as shown in below

 NSString *path = [[NSBundle mainBundle] pathForResource:
                  @"WellList" ofType:@"plist"];
NSMutableDictionary *root = [[NSMutableDictionary alloc] initWithContentsOfFile:path];
NSString* latitude = [[[[[root objectForKey: @"Routes"] objectForKey: @"Houston" ] objectForKey: @"Location 1"] objectForKey: @"coordinate"] objectForKey: @"latitude"]; 

我想使用循环访问plist中的每个坐标并将其添加到我的NSmutableArray中.

I would like to use loop to access every single coordinate in my plist and add them into my NSmutableArray.

推荐答案

NSMutableDictionary *root = [[NSMutableDictionary alloc] initWithContentsOfFile:path];
NSDictionary *routes = [root objectForKey: @"Routes"];
NSArray *cities = [routes allValues];
for (NSDictionary *city in cities) {
    NSArray *locations = [city allValues];
    for (NSDictionary *loc in locations) {
        NSDictionary *coord = [loc objectForKey:@"coordinate"];
        NSLog(@"%@",[coord objectForKey:@"latitude"]);

    }
}
