IOS MJRefresh pull-down refresh pull-up and load (you can add a gif) Summary

1. First download the latest MJ refresh library on github. Download the MJ Link

 

 

2. Add related code to tableVIew

_ TableView = [[UITableView alloc] initWithFrame: CGRectMake (0, 0, MCAPPWidth, MCAPPHeight-64)];

_ TableView. backgroundColor = myClearColor;

_ TableView. separatorStyle = UITableViewCellSeparatorStyleNone;

_ TableView. delegate = self;

_ TableView. dataSource = self;

_ TableView. showsVerticalScrollIndicator = NO;

_ TableView. scrollsToTop = YES;

[Self. view addSubview: _ tableView];

[_ TableView addGifHeaderWithRefreshingTarget: self refreshingAction: @ selector (loadData)];

[_ TableView addGifFooterWithRefreshingTarget: self refreshingAction: @ selector (loadMoreData)];

[Self gif];

 

// LoadData: The method for requesting network data when you pull down and refresh the Refresh. loadMoreData is the method for requesting network data when you pull and load the data.

 

 

3. [self gif]

 

-(Void) gif

{

NSMutableArray * idleImages = [NSMutableArray array];

// This gif image appears when you refresh it. It needs to be added to the array cyclically.

For (NSUInteger I = 1; I <= 5; I ++ ){

UIImage * image = [UIImage imageNamed: [NSString stringWithFormat: @img_loading-%lu.png, (unsigned long) I];

[IdleImages addObject: image];

}

Pai_tableview.gif Header setImages: idleImages forState: MJRefreshHeaderStateIdle];

_TableView.gif Footer. refreshingImages = idleImages;

_TableView.gif Header. updatedTimeHidden = YES;

// Set the animation image to be refreshed (the status will be refreshed when it is released)

NSMutableArray * refreshingImages = [NSMutableArray array];

For (NSUInteger I = 1; I <= 5; I ++ ){

UIImage * image = [UIImage imageNamed: [NSString stringWithFormat: @img_loading-%lu.png, (unsigned long) I];

[RefreshingImages addObject: image];

}

Pai_tableview.gif Header setImages: refreshingImages forState: MJRefreshHeaderStatePulling];

}

 

 

4. Customize the Label and gif frame at the bottom of the top when refreshing. Here is an example of footer.

MJRefreshGifFooter. m

-(Void) layoutSubviews

{

[Super layoutSubviews];

// Specifies the frame of the gif image.

Self.gif View. frame = CGRectMake (self. bounds. origin. x + 20, self. bounds. origin. y + 15, self. bounds. size. width/2, self. bounds. size. height/2 );

 

If (self. stateHidden ){

Self.gif View. contentMode = UIViewContentModeCenter;

} Else {

Self.gif View. contentMode = UIViewContentModeScaleAspectFit;

Self.gif View. mj_w = self. mj_w * 0.5-90;

}

}

MJRefreshFooter. m

-(Void) layoutSubviews

{

[Super layoutSubviews];

Self. loadMoreButton. frame = self. bounds;

Self. loadMoreButton. hidden = YES;

// Frame of the Label

Self. stateLabel. frame = CGRectMake (self. bounds. origin. x, self. bounds. origin. y + 15, self. bounds. size. width, self. bounds. size. height/2 );

Self. noMoreLabel. frame = self. bounds;

}

 

Similarly, the gif frame and Labelframe of the header can be modified as needed in the methods in the corresponding class.
