iOS 17之后,真机调试Beta版本必须使用Beta版本的Xcode来调试,用以前复制DeviceSupport 方式无法调试,新的Beta版本Xcode中,已经不包含 iOS 17目录。如下图:
解决方案:
1)下载最新的Beta 版本Xcode 15
2)运行命令defaults write com.apple.dt.Xcode DVTEnableCoreDevice enabled
此时旧版本Xcode 将会出现一个 CoreDevice ,这时候就可以继续Debug调试了
运行旧版本项目编译报以下错误
Showing All Messages Assertion failed: (aliasSectionNum == sectionNum && "alias and its target must be located in the same section"), function assignAliasAtomOffsetInSection, file Layout.cpp, line 3248.
解决:Build Settings -> Other Linker Flags
中添加 -ld64
*** Assertion failure in void _UIGraphicsBeginImageContextWithOptions(CGSize, BOOL, CGFloat, BOOL)(), UIGraphics.m:410
解决方案:将下面代码替换
UIGraphicsBeginImageContextWithOptions(self.bounds.size, self.opaque, self.contentsScale);
CGContextRef context = UIGraphicsGetCurrentContext();
if (self.opaque) {
CGSize size = self.bounds.size;
size.width *= self.contentsScale;
size.height *= self.contentsScale;
CGContextSaveGState(context); {
if (!self.backgroundColor || CGColorGetAlpha(self.backgroundColor) < 1) {
CGContextSetFillColorWithColor(context, [UIColor whiteColor].CGColor);
CGContextAddRect(context, CGRectMake(0, 0, size.width, size.height));
CGContextFillPath(context);
}
if (self.backgroundColor) {
CGContextSetFillColorWithColor(context, self.backgroundColor);
CGContextAddRect(context, CGRectMake(0, 0, size.width, size.height));
CGContextFillPath(context);
}
} CGContextRestoreGState(context);
}
task.display(context, self.bounds.size, ^{return NO;});
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
self.contents = (__bridge id)(image.CGImage);
替换为:
UIGraphicsImageRendererFormat *format = [[UIGraphicsImageRendererFormat alloc] init];
format.opaque = self.opaque;
format.scale = self.contentsScale;
UIGraphicsImageRenderer *renderer = [[UIGraphicsImageRenderer alloc] initWithSize:self.bounds.size format:format];
UIImage *image = [renderer imageWithActions:^(UIGraphicsImageRendererContext * _Nonnull rendererContext) {
CGContextRef context = rendererContext.CGContext;
if (self.opaque) {
CGSize size = self.bounds.size;
size.width *= self.contentsScale;
size.height *= self.contentsScale;
CGContextSaveGState(context); {
if (!self.backgroundColor || CGColorGetAlpha(self.backgroundColor) < 1) {
CGContextSetFillColorWithColor(context, [UIColor whiteColor].CGColor);
CGContextAddRect(context, CGRectMake(0, 0, size.width, size.height));
CGContextFillPath(context);
}
if (self.backgroundColor) {
CGContextSetFillColorWithColor(context, self.backgroundColor);
CGContextAddRect(context, CGRectMake(0, 0, size.width, size.height));
CGContextFillPath(context);
}
} CGContextRestoreGState(context);
}
task.display(context, self.bounds.size, ^{return NO;});
}];
self.contents = (__bridge id)(image.CGImage);
