A simple way to implement page jumps in IOS application development Note _ios

As a new handwritten note, it is convenient for you to remember:

From Android to the iOS, for the page jump, looking for a lot of information, now record the page jump method.

1. With Navigationcontroller

2. Jump directly (just found on the internet, not too familiar, wrong Mo Strange)

1. Build a Rootviewcontroller, in delegate.h

Copy Code code as follows:

@property (Strong, nonatomic) Uiviewcontroller *viewcontroller;
@property (Strong, nonatomic) Uinavigationcontroller *navcontroller;

Write code in the DELEGATE.M code didfinishlaunchingwithoptions function:

Rootviewcontroller *rootview = [[Rootviewcontroller alloc] init];
Rootview.title = @ "Root View";

Self.navcontroller = [[Uinavigationcontroller alloc] init];

[Self.navcontroller Pushviewcontroller:rootview Animated:yes];
[Self.window AddSubview:self.navController.view];

The code loads the first page Rootviewcontroller.
Jump to another page (such as Subviewcontroller) code:

Copy Code code as follows:

Subviewcontroller *subview = [[Subviewcontroller alloc] init];
[Self.navigationcontroller Pushviewcontroller:subview Animated:yes];
Subview.title = @ "Sub";

The benefit is that the return button is automatically generated.

2. Direct jump, nothing

Do not need to do other redundant, directly create a View object

Copy Code code as follows:

Subviewcontroller *subview = [[Subviewcontroller alloc] initwithnibname:@ "Subviewcontroller" Bundle:[NSBundle Mainbundle]];
[Self Presentmodalviewcontroller:subview animated:yes];

That's good.

iOS6.0 doesn't use this function after all.

Copy Code code as follows:

[Self Presentmodalviewcontroller:subview animated:yes];

Can replace

Copy Code code as follows:

[Self Presentviewcontroller:subview animated:yes completion:nil];

Data transfer when a page jumps
For example, in the need to implement View1 jump to View2, the view1 of some of the data passed to View2

Ideas:

1. Customize a bean class user and implement user as a member variable in VIEW2.

2.view1 the data into user when it jumps, and assigns it to View2.user

Code

1. View2

. h declaring member variables

Copy Code code as follows:

@property (Strong, nonatomic) User *user;

2. View1

Copy Code code as follows:

View2 *view2 = [[View2 alloc] init];
User *user = [[User alloc] init];
User.Name = @ "Kevin";
View2.user = user;
[Self.navigationcontroller Pushviewcontroller:view2
Animated:yes];

3. View2

Take the variable

Copy Code code as follows:

Self.user.name
