Question

iam 拟通过<条码>修改我的<条码> 查询/编码>文档,但存在问题:

i have 100 HTML files that loaded on UIWebView , so i want implement something like this : if user swipes the view my webView will load next html file but the problem is my code just load first HTML file :

NSString *path = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"file%d",+1] ofType:@"html"];
NSFileHandle *readHandle = [NSFileHandle fileHandleForReadingAtPath:path];

NSString *htmlString = [[NSString alloc] initWithData: 
                        [readHandle readDataToEndOfFile] encoding:NSUTF8StringEncoding];


[self.myWebView loadHTMLString:htmlString baseURL:nil];

Answer 1

<代码>[NSString stringWithFormat:@"file%d”,+1]将始终如一地退还file1,因此,你总是重装file1.html。

您是否打算使用反射或指数而不是第1号?

EDIT: 更多法典。这是我建议如何落实的,但它应当给你一个想法,而且它相对是紧凑的。 (一) 利用ivar或财产跟踪现行档案指数。)

static NSInteger currentIndex = 0;
if (currentIndex < 99) {
    currentIndex++;
}
NSString *path = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"file%d",currentIndex] ofType:@"html"];
NSFileHandle *readHandle = [NSFileHandle fileHandleForReadingAtPath:path];
NSString *htmlString = [[NSString alloc] initWithData: 
                        [readHandle readDataToEndOfFile] encoding:NSUTF8StringEncoding];
[self.myWebView loadHTMLString:htmlString baseURL:nil];
