为了SObject捕捉alloc:
NSObject *obj = [[NSObject alloc] init];
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
NSString *str = [[NSString alloc] init];
[...]
在其他方法中执行都正常,只有在NSObjet的 alloc 有问题。
谁知道原因?
#import "NSObject+Custom.h"
#import <objc/runtime.h>
@implementation NSObject (Custom)
+ (void)load
{
Method original = class_getInstanceMethod(self, @selector(alloc));
Method swizzle = class_getInstanceMethod(self, @selector(allocCustom));
method_exchangeImplementations(original, swizzle);
}
- (id)allocCustom
{
NSLog(@"%s", __FUNCTION__); // no way
return [self allocCustom];
}
@end
