1.TableView不顯示沒內容的Cell怎麼辦?

self.tableView.tableFooterView = [[UIView alloc] init];

2.自定義了leftBarbuttonItem左滑返回手勢失效了怎麼辦?

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]

initWithImage:img

style:UIBarButtonItemStylePlain

target:self

action:@selector(onBack:)];

self.navigationController.interactivePopGestureRecognizer.delegate = (id)self;
 

（最好在父控制器裡寫）

3.ScrollView莫名其妙不能在viewController劃到頂怎麼辦?

self.automaticallyAdjustsScrollViewInsets = NO;

4.鍵盤事件寫的好煩躁,都想摔鍵盤了,怎麼辦?

使用IQKeyboardManager(github上可搜尋)

5.1、禁止手機睡眠

[UIApplication sharedApplication].idleTimerDisabled = YES;

6.隱藏某行cell

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

{

// 如果是你需要隱藏的那一行，返回高度為0

if(indexPath.row == YouWantToHideRow)

return 0;

return 44;

}// 然後再你需要隱藏cell的時候呼叫

[self.tableView beginUpdates];

[self.tableView endUpdates];
 

7.禁用button高亮

button.adjustsImageWhenHighlighted = NO;

或者在建立的時候

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

8.畫水印

// 畫水印

- (void) setImage:(UIImage *)image withWaterMark:(UIImage *)mark inRect:(CGRect)rect

{

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 4.0)

{

UIGraphicsBeginImageContextWithOptions(self.frame.size, NO, 0.0);

}

//原圖

[image drawInRect:self.bounds];

//水印圖

[mark drawInRect:rect];

UIImage *newPic = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

self.image = newPic;

}
 

9.cell去除選中效果

cell.selectionStyle = UITableViewCellSelectionStyleNone;

10.cell點按效果

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

[tableView deselectRowAtIndexPath:indexPath animated:YES];

}
