A static UITabelView solution ---- CTStaticTableView, ios static tableviewCTStaticTableView This is a method of encapsulating static TableView with code. You can use xib to initialize CTStaticTableView, or use the code: self.tableView = [[CTStaticTableView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)]; [self.view addSubview:self.tableView]; Then you can synthesize your static table view cell.T

Optimized TableView Correct use of ' reuseidentifier ' to reuse cells Try to make all view opaque, including the cell itself, minimize unnecessary transparent view Try to avoid gradient effects, picture scaling, off-screen rendering Cache Row Height If the real content within the cell comes from the web, using asynchronous loading, the cache request results Use ' Shadowpath ' to draw shadows Reduce the number of subviews, for s

Study TableView How to calculate dynamic row height study for two days has not been very likely, today finally made out the desired effect.First of all, I collected a lot of information on the Internet, the summary of various great gods, and then began to look at, research, testing, the basic ideas are the same.1. Be sure to set the label's numberofline to 02. Size required for text message3. set the height of the label to Titlesize.height4. In- (CGFl

One: What is the optimization of tableview and why should it be optimized1) CPU (central processing unit) and GPU (graphics processor): The CPU is mainly engaged in some work of logic calculation; The GPU is mainly engaged in graphics processing.2) The common denominator between CPU and GPU:Have their own cache system, all have their own numbers and logic units, are designed to complete the task of computing.3) different points of CPU and GPU:CPU core

TableView, pull-down effects are all over the street, and there are a lot of third-party code.These two days have studied the principle, share the idea. Here take TableView's pull as an example, because the style of the pull-up operation is also many, here only one: in the pull-up tableview, under the bottom of tableview, add a view, the view can be customized. I

IOS teaches you how to play with UITableViewController and TableView and iostableview In iphone and Ipad development, UITableViewController and TableView are usually used. However, you will get bored with writing too much of these controls. How can I keep this control usable? How can I make it easy to write. Yes. In particular, UITableViewController integrates dataSouce's business logic on itself and makes

Questions that are often asked in UITableViewThe principle of the cell's heavy use• What's more? A very important question: Is it sometimes necessary? Custom UITableViewCell (? A subclass inherits UITableViewCell),? And every one? It must be the same kind of uitableviewcell, so? A uitableview may have different types of uitableviewcell, and there will be many different types of UITableViewCell in the object pool, so UITableView may get the wrong type when using UITableViewCell. UITableViewCell•

If you create a tableview and return a cell with only a few rows, not enough to fill the screen, and then you add a gesture on the tableview you created, how do you make the cell's click event not conflict with the Click event of the gesture? In fact, you just have to do one step: the proxy method for implementing gestures is as follows-(BOOL) Gesturerecognizer: (Uigesturerecognizer *) Gesturerecognizer Sho

Programme IWhen the Navigationcontroller is used, when the interface jumps back and forth, sometimes the TableView or collectionview move up, and it usually automatically moves up to 64 pixels, then this is the case We can turn off the TableView auto-fit layout.Self.automaticallyadjustsscrollviewinsets = no;//default is yesScenario Two:When the TableView overall

1. Set TableView directly to Self.tableView.separatorStyle = Uitableviewcellseparatorstylenone. Then customize the cell where you add a view, the height is 1, the color set itself.2. Add these two methods-(void) viewdidlayoutsubviews{if ([Self.tableview respondstoselector: @selector (setseparatorinset:)]) {[Self.tableview Setseparatorinset:uiedgeinsetsmake (0,0,0,0)];}if ([Self.tableview respondstoselector: @selector (setlayoutmargins:)]) {[Self.table

[Swift learning] Swift programming tour-expansion (24), swift tour An extension adds new features to an existing class, struct, or enumeration type, including attributes and Methods. If you define an extension to add new features to an existing type, this new function is available to all existing instances of this type, even if they are defined before your extens

Swift Study Notes (23)-Swift generic knowledge, swift Study Notes The concept of generics also exists in Java. Generics can make code more refined and are an optimization for data types. Now there is the same requirement: Write a struct, and then judge whether the integer is equal. The implementation code and output are as follows: . If there is another dema

First we drag and drop a default TableView control! Look at the inspector of the Xcode5 Panel (inspector)We can find a Separator insetss tag defaults to the defaultWe chose to find a custom at this time we are surprised to find that left 15, when we just change this 15 to 0, and then save, you will find the TableView line is the same as before.Some friends asked if the code is written tableview.Let's go on

TableView Select a row, do not display the selected color, do not set the TableView allowsselection to No, which may cause tableview can not respond to the click action. A reasonable solution is to: directly at the time of creating the cell: Cell.selectionstyle = Uitableviewcellselectionstylenone; Or you can create a cell through Xib . It is also possible to writ
