ios - 如何为所有推送序列创建符号断点？
<p><p>我目前正在调试我的应用程序，并且遇到了正在执行 segue 的问题，但我终其一生都无法弄清楚它是从哪里调用的。</p>
<p>我想知道是否可以添加一个断点，以便应用程序暂停并显示调用它的行？</p>
<p>我尝试添加一个符号断点，但无法正常工作。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>为 UIViewController 创建类别并将其添加到其中:</p>
<pre><code>+ (void)load {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
Class class = ;
SEL originalSelector = @selector(prepareForSegue:sender:);
SEL swizzledSelector = @selector(yd_prepareForSegue:sender:);
Method originalMethod = class_getInstanceMethod(class, originalSelector);
Method swizzledMethod = class_getInstanceMethod(class, swizzledSelector);
BOOL didAddMethod = class_addMethod(class, originalSelector, method_getImplementation(swizzledMethod), method_getTypeEncoding(swizzledMethod));
if (didAddMethod) {
class_replaceMethod(class, swizzledSelector, method_getImplementation(originalMethod), method_getTypeEncoding(originalMethod));
} else {
method_exchangeImplementations(originalMethod, swizzledMethod);
}
});
}
- (void)yd_prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
;
NSLog(@"prepareForSegue From: %@", self);
}
</code></pre></p>
