所有tableViewController 繼承這個基類.把處理代碼寫在基類
#import "BaseTabVc.h"
@interface BaseTabVc ()
@end
@implementation BaseTabVc
- (void)viewDidLoad {
[super viewDidLoad];
[self seting];
}
-(void)seting{
//? ? self.automaticallyAdjustsScrollViewInsets = NO;
BOOL isRealize = [self.tableView respondsToSelector:@selector(contentInsetAdjustmentBehavior)];
if (isRealize) {
self.tableView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
}else{
self.automaticallyAdjustsScrollViewInsets = NO;
}
}
