我对UIWebView的loadHTMLString有一个奇怪的问题,当我用我的内容HTML字符串调用loadHTMLString时,它只会显示一个空白视图.htmlstring的内容无关紧要,它什么都不做.
奇怪的是,几周前我曾经在模拟器和设备上进行测试.我的代码如下:
NSMutableString *sHtmlBuf = [NSMutableString stringWithString:@"<body style=\"background-color: #000000; color: #FFFFFF; font-family: Helvetica; font-size: 10pt; width: 300px; word-wrap: break-word;\">"];
if ([m_oCallArray count] > 0 || [m_oPutArray count] > 0) {
[sHtmlBuf appendString:sWarrTitle];
if ([m_oCallArray count] > 0) {
NSString *formattedCall = [NSString stringWithFormat:@"%@ %@<br />",sCallTitle,[self arrayToString:m_oCallArray]];
[sHtmlBuf appendFormat:@"%@ ",formattedCall];
}
if ([m_oPutArray count] > 0) {
NSString *formattedPut = [NSString stringWithFormat:@"%@ %@<br />",sPutsTitle,[self arrayToString:m_oPutArray]];
[sHtmlBuf appendFormat:@"%@ ",formattedPut];
}
}
if ([m_oBullArray count] > 0 || [m_oBearArray count] > 0) {
[sHtmlBuf appendString:sCbbcTitle];
if ([m_oBullArray count] > 0) {
NSString *formattedBull = [NSString stringWithFormat:@"%@ %@<br />",sBullTitle,[self arrayToString:m_oBullArray]];
[sHtmlBuf appendFormat:@"%@ ",formattedBull];
}
if ([m_oBearArray count] > 0) {
NSString *formattedBear = [NSString stringWithFormat:@"%@ %@<br />",sBearTitle,[self arrayToString:m_oBearArray]];
[sHtmlBuf appendFormat:@"%@ ",formattedBear];
}
}
if ([m_oOtherArray count] > 0) {
NSString *formattedOther = [NSString stringWithFormat:@"%@ %@<br />",sOtherTitle,[self arrayToString:m_oOtherArray]];
[sHtmlBuf appendFormat:@"%@ ",formattedOther];
}
[m_oDataPresentView loadHTMLString:sHtmlBuf baseURL:nil];
(注意:HTML可以在此问题之前在常规Web浏览器上呈现,因此HTML不是问题)
编辑:添加初始化代码:
//Create wcbbc panel
wcbbcPanel = [[WarrantsAndCbbc alloc] initWithFrame:CGRectMake(320, 0, 320, 230)];
[m_oMainContentScrollView addSubview:wcbbcPanel];
UIView初始化代码:
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
// Initialization code.
CGRect oFrame = frame;
CGPoint oPositionCoords = CGPointMake(0, 0);
oFrame.origin = oPositionCoords;
m_oDataPresentView = [[UIWebView alloc] initWithFrame:oFrame];
[m_oDataPresentView loadHTMLString:@"<html><body style=\"background-color: #000000; color: #FFFFFF; font-family: Helvetica; font-size: 10pt; width: 300px; word-wrap: break-word;\"></body></html>" baseURL:nil];
m_oDataPresentView.delegate = self;
[self addSubview:m_oDataPresentView];
}
return self;
}

经过一些侦探工作,我发现在委托函数中返回NO
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
将拒绝loadHTMLString请求.返回YES解决了我的问题.
我只是遇到了同样的问题,并且作为一个n00b,我发现自己感到惊讶,当我没有做的时候问题就解决了
webview = [[UIWebView alloc]init];
但相反,由于它已经作为插座接线,我只需要打电话
[webView loadHTMLString:mystring baseURL:nil];
