1:uitableviewcell Drawinrect failed in iOS7

Workaround, move the layout of the cell into the new view, implement the Drawinrect in the view, and load the view inside the cell with the following code:

@implementation customtableviewcell-(ID) Initwithstyle: (Uitableviewcellstyle) style Reuseidentifier: (NSString *) reuseidentifier{self    = [super Initwithstyle:style reuseidentifier:reuseidentifier];    if (self) {        [Self.contentview addsubview:[[customcontentview alloc]initwithframe:self.contentview.bounds];    }    return self;} @end

@implementation customcontentview-(ID) initWithFrame: (cgrect) frame{self    = [Super Initwithframe:frame];    if (self) {        Self.backgroundcolor = [Uicolor clearcolor];    }    return self;} -(void) DrawRect: (cgrect) rect{    nsdictionary * attributes = @{                                  nsfontattributename: [Uifont fontwithname:@] Helvetica-bold "Size:12",                                  nsforegroundcolorattributename: [Uicolor blackcolor]                                  };    [@ "I <3 IOS 7" Drawinrect:rect withattributes:attributes];} @end

4:github readme.md Add a picture

Briefly:

Put the picture in the warehouse, link it in the file, and push it to GitHub.

GitHub Image Link Format:

(http://github.com/yourname/your-repository/raw/master/images-folder/xxx.png)

Then add in readme.md:

For example: I am in my Dotvim folder next screenshots directory, there is a vim-screenshot.jpg in this directory. So the way to add links is as follows

! [Image] (https://github.com/ButBueatiful/dotvim/raw/master/screenshots/vim-screenshot.jpg)

Note: When you finish writing the Readme file for the first time, it will be saved to the project, if you want to modify it, you can modify it locally, and then push to the remote project;

5: Settings for navigation bar transparency and top layout start position

Property: Translucent

Shut down

Self.navigationController.navigationBar.translucent = NO;

Open

Self.navigationController.navigationBar.translucent = YES;

When Automaticallyadjustsscrollviewinsets is NO, TableView starts at the top of the screen, which is covered by the navigation bar & status bar

When Automaticallyadjustsscrollviewinsets is YES, it is also the default behavior
