iOS Development-Auto-hide keyboard and status bar

1. Hide the status bar

After iOS upgraded to 7.0, many APIs were abolished, and the original method of hiding the status bar StatusBar was invalidated.

Original plan

[[UIApplication sharedapplication] setstatusbarhidden:yes];
Unfortunately, it worked in later versions, so we can use the new API to implement the purpose of the hidden State column, as follows:
-(BOOL) prefersstatusbarhidden{    return YES;

2. Automatically hide the keyboard and automatically layout

The solution provided here is suitable for any type of keyboard, mainly considering that Numberpad has no return key.

It is also a scheme based on Scrollerview for layout, using the animated effect of Scrollerview.

The code is as follows:

@implementation testviewcontroller-(void) viewdidload {    [super viewdidload];    Do any additional setup after loading the view.    [_scrollview Addgesturerecognizer:[[uitapgesturerecognizer alloc] initwithtarget:self action: @selector ( Hidekeyboard)]];} -(void) textfielddidbeginediting: (Uitextfield *) textfield{    //keyboard height is 216    [_scrollview setframe:cgrectmake (0, 0, _scrollview.frame.size.width, _scrollview.frame.size.height+216)];    [_scrollview setcontentoffset:cgpointmake (0) animated:yes];    [_scrollview settag:0];    } -(void) hidekeyboard{    if (_scrollview.tag==0) {        [_scrollview setcontentoffset:cgpointmake (0, 0) animated:yes ];        [_scrollview setframe:cgrectmake (0, 0, _scrollview.frame.size.width, _scrollview.frame.size.height-216)];        [Self.view Endediting:yes];        [_scrollview settag:1];}}}
