iOS Some pages in can also be embedded WebView, then WebView of use H5 Made a navigation , and iOS The color of the status bar is difficult to adjust H5 The color of the navigation is the same . As shown in the figure below :

In fact, this kind of reason , Mainly because of the use of 16 Binary color , Causes color conversion to deviate .

I'm here because H5 What is the color in the picture #3983E5, Instead, it uses the following method to transform UIColor Error :

+ (UIColor *) colorWithHexString: (NSString *)color
{
    NSString *cString = [[color stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] uppercaseString];
    
    // String should be 6 or 8 characters
    if ([cString length] < 6) {
        return [UIColor clearColor];
    }
    
    // strip 0X if it appears
    if ([cString hasPrefix:@"0X"])
        cString = [cString substringFromIndex:2];
    if ([cString hasPrefix:@"#"])
        cString = [cString substringFromIndex:1];
    if ([cString length] != 6)
        return [UIColor clearColor];
    
    // Separate into r, g, b substrings
    NSRange range;
    range.location = 0;
    range.length = 2;
    
    //r
    NSString *rString = [cString substringWithRange:range];
    
    //g
    range.location = 2;
    NSString *gString = [cString substringWithRange:range];
    
    //b
    range.location = 4;
    NSString *bString = [cString substringWithRange:range];
    
    // Scan values
    unsigned int r, g, b;
    [[NSScanner scannerWithString:rString] scanHexInt:&r];
    [[NSScanner scannerWithString:gString] scanHexInt:&g];
    [[NSScanner scannerWithString:bString] scanHexInt:&b];
    
    return [UIColor colorWithRed:((float) r / 255.0f) green:((float) g / 255.0f) blue:((float) b / 255.0f) alpha:1.0f];
}

You can check it , In your project H5 Is it also used in the classroom 16 Binary color .

And then I made a custom one 16 Color conversion to UIColor Methods .

Want to make the navigation bar color and status bar color exactly the same , So just another way .

Use RGBA Color representation is enough .RGBA , respectively, It's red 、 green 、 Blue 、 transparency .

such as , I'm here H5 Change the color of the navigation bar to (1,159,239,1), And then in the project, you just need to put self.view The background color of [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:a], Just show it .

About this API, Generally, a short macro is defined .

#define RGB(r, g, b, a) [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:a]

I set it like this here self.view Background color of :

self.view.backgroundColor = RGB(1,159,239,1);

The colors of the navigation bar and the status bar are exactly the same .
