到一个新公司，最艰难的时刻就是前一周，项目代码不熟悉，人也都不认识，关键项目文档还> 缺失，尼玛，真是各种不爽
刚入新公司时，一般不可能对项目结构快速掌握，假如任务是类似修改页面的bug，就找页面对应文件可能就很费事，多个页面的话简直能让人找的上火。如果能迅速定位当前页面及相关跳转页面文件位置，那么问题就能变得简单些。
-
使用category动态添加的方法，release时自动关闭打印位置，对工程无影响
-
一键导入，只需导入头文件"UIViewController+SWIZZLocaltion.h"，简单方便
-
尽可能详细的描述跳转信息，有更详尽的描述方案敬请留言
核心代码片段
#ifdef DEBUG
+ (void)load{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
Method orginWillAppear = class_getInstanceMethod([self class], @selector(viewWillAppear:));
Method swizWillAppear = class_getInstanceMethod([self class], @selector(location_viewWillAppear:));
bool isAddWillAppear = class_addMethod([self class], @selector(viewWillAppear:), method_getImplementation(swizWillAppear), method_getTypeEncoding(swizWillAppear));
if (isAddWillAppear) {
class_replaceMethod([self class], @selector(location_viewWillAppear:), method_getImplementation(orginWillAppear), method_getTypeEncoding(orginWillAppear));
} else {
method_exchangeImplementations(orginWillAppear, swizWillAppear);
}
});
}
#endif
#pragma mark - SwizzMethods
- (void)printViewLocaltiionAndJumpRelation{
if (![self isKindOfClass:[UITabBarController class]]&&![self isKindOfClass:[UINavigationController class]]) {
NSString *logStr;
if ([[self parentViewController] isKindOfClass:[UINavigationController class]]) {
logStr = @"push跳转";
if (self.presentingViewController) {
logStr = @"present+Navi跳转";
}
for (UIViewController *viewControl in self.navigationController.viewControllers) {
logStr = [logStr stringByAppendingFormat:@"-->%@",[viewControl.class description]];
}
}else if(self.presentingViewController){//presentingViewController 上一视图
logStr = @"present跳转-->";
if ([self.presentingViewController isKindOfClass:[UINavigationController class]]) {
UINavigationController *navi = (UINavigationController *)self.presentingViewController;
logStr = [logStr stringByAppendingFormat:@"%@-->%@",[[navi.viewControllers lastObject].class description],[self.class description]];
}else{
logStr = [logStr stringByAppendingFormat:@"%@-->%@",[self.presentingViewController.class description],[self.class description]];
}
}else{
logStr = [NSString stringWithFormat:@"未知跳转-->%@",[self.class description]];
}
NSLog(@"强大的黑魔法 %@",logStr);
}
}
最后附上小demo：ViewControllerLocaltion
