iOS读取info.plist中的值

在app运行的时候，需要读取info.plist中的信息，用以下代码可获取整个info.plist的信息

[[NSBundle mainBundle] infoDictionary]

以下为根据 key 值去取 URLTypes 里面对应的值：

+ (NSString *)URLSchemesForkey:(NSString *)key {

    NSDictionary *dict = [[NSBundle mainBundle] infoDictionary];
    NSArray *urlTypes = dict[@"CFBundleURLTypes"];
    NSString *urlSchemes = nil;
    for (NSDictionary *scheme in urlTypes) {
        NSString *schemeKey = scheme[@"CFBundleURLName"];
        if ([schemeKey isEqualToString:key]) {
            urlSchemes = scheme[@"CFBundleURLSchemes"][];
            break;
        }
    }
    return urlSchemes;
}

info.plist所有的信息,示例如下：
