ios-最佳途徑把url參數轉換為字符串值

最佳途徑把url參數轉換為字符串值

在iphong中把url分割為數值，我的計劃是這樣：

appname://user=jonsmith&message=blah%20blah

這樣我可以將user和message作為兩個NSString接收。有沒有更好的方法？謝謝

最佳回答：

假設你的URL是名為url的NSURL

NSMutableDictionary *queryParams = [[NSMutableDictionary alloc] init];
NSArray *components = [[url query] componentsSeparatedByString:@"&"];

for (NSString *component in components) {
    NSArray *pair = [component componentsSeparatedByString:@"="];

    [queryParams setObject:[[pair objectAtIndex:1] stringByReplacingPercentEscapesUsingEncoding: NSMacOSRomanStringEncoding]
                    forKey:[pair objectAtIndex:0]]; 
}

...

[queryParams release];
