Решение этой проблемы состоит из нескольких этапов.Во-первых, нам нужно добавить main.m в наш Swift, чтобы можно было внедрить код в исходном решении.В проектах Swift основной файл абстрагируется.Обратитесь к этому сообщению .
Итак, первым шагом является удаление ключевого слова @UIApplicationMain из AppDelegate класса.
Затем мы добавляем main.m, добавляя файл Objective-Cm и называя его main
.
Добавьте следующий код, как показано ниже, в main.m файле
#import <UIKit/UIKit.h>
#import "MoviePlayerDemo-Swift.h"
extern void WorkaroundInlinePlayerFullScreenButtonBug(void);
int main(int argc, char *argv[])
{
@autoreleasepool
{
WorkaroundInlinePlayerFullScreenButtonBug();
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
Исходный код смены значков остается таким же, как и в исходном ответ :
@import MediaPlayer;
@import ObjectiveC;
static void (*configureAuxiliaryButtonsIMP)(id, SEL, BOOL);
static void ConfigureAuxiliaryButtons(id self, SEL _cmd, BOOL flag)
{
configureAuxiliaryButtonsIMP(self, _cmd, flag);
@try
{
id delegate = [self delegate]; // Either nil or MPInlineVideoController (responds to `isFullscreen`) or MPInlineVideoFullscreenViewController (does not respond to `isFullscreen`)
BOOL isFullscreen = [delegate respondsToSelector:@selector(isFullscreen)] ? [delegate isFullscreen] : YES;
NSString *imageName = [@[ @"Video", @"Player", @"_", isFullscreen ? @"Exit" : @"Enter", @"Fullscreen" ] componentsJoinedByString:@""];
SEL imageNamedForControlState = NSSelectorFromString([@[ @"_", @"image", @"Named", @":", @"for", @"Control", @"State", @":" ] componentsJoinedByString:@""]);
UIImage *normalImage = ((UIImage *(*)(id, SEL, NSString *, UIControlState))objc_msgSend)(self, imageNamedForControlState, imageName, UIControlStateNormal);
UIImage *highlightedImage = ((UIImage *(*)(id, SEL, NSString *, UIControlState))objc_msgSend)(self, imageNamedForControlState, imageName, UIControlStateHighlighted);
UIButton *fullscreenButton = [self valueForKey:[@[ @"fullscreen", @"Button" ] componentsJoinedByString:@""]];
[fullscreenButton setImage:normalImage forState:UIControlStateNormal];
[fullscreenButton setImage:highlightedImage forState:UIControlStateHighlighted];
}
@catch (NSException *exception)
{
NSLog(@"Failed to workaround inline player fullscreen button bug: %@", exception);
}
}
void WorkaroundInlinePlayerFullScreenButtonBug(void)
{
if (![NSProcessInfo.processInfo isOperatingSystemAtLeastVersion:(NSOperatingSystemVersion){10, 0, 0}])
return;
Class MPVideoPlaybackOverlayView = NSClassFromString([@[ @"M", @"P", @"Video", @"Playback", @"Overlay", @"View" ] componentsJoinedByString:@""]);
SEL configureAuxiliaryButtonsSEL = NSSelectorFromString([@[ @"_", @"configure", @"Auxiliary", @"Buttons", @":" ] componentsJoinedByString:@""]);
NSMethodSignature *methodSignature = [MPVideoPlaybackOverlayView instanceMethodSignatureForSelector:configureAuxiliaryButtonsSEL];
if (methodSignature.numberOfArguments != 3)
{
NSLog(@"Failed to workaround inline player fullscreen button bug (method not found)");
return;
}
const char *returnType = methodSignature.methodReturnType;
const char *argType = [methodSignature getArgumentTypeAtIndex:2];
if (strcmp(returnType, @encode(void)) != 0 || strcmp(argType, @encode(BOOL)) != 0)
{
NSLog(@"Failed to workaround inline player fullscreen button bug (type mismatch)");
return;
}
Method configureAuxiliaryButtons = class_getInstanceMethod(MPVideoPlaybackOverlayView, configureAuxiliaryButtonsSEL);
configureAuxiliaryButtonsIMP = (__typeof__(configureAuxiliaryButtonsIMP))method_getImplementation(configureAuxiliaryButtons);
method_setImplementation(configureAuxiliaryButtons, (IMP)ConfigureAuxiliaryButtons);
}
