Simple use of iOS development--xcode

Simple use of Xcode

First, the use of shortcut keys

The following shortcut keys are commonly used:

New

Shift + CMD + N New Project

CMD + N New file

View

Option + cmd + ENTER to open assistant editor

CMD + return display main window

cmd + 0 Navigation window

Option + cmd + 0 tool window

Switch between. M & H control + cmd + up/Down

Switch between control + cmd and around in the order of the Browse files

View header file Control + cmd + j

Switch to the corresponding function control + 6 support smart Input, note input method

Run

CMD + R Run

CMD +. Stop it

CMD + b Compilation

CMD + SHIFT + B static memory analysis compilation to check for memory leaks on the program structure

Typesetting

Control + I re-indent the selected button

CMD +] Increase indent to the right

CMD + [Decrease Indent to the left]

CMD +/comment/uncomment, hint: When uncomment is canceled, the comment double slash must be at the beginning of the line

cmd + up to file start position

CMD + down to file end position

2, F6 single-step debugging, F7 jump, F8 continue, and Eclipse,vs similar

Second, OC Proprietary annotations

annotation forms and effects

(1) #pragma mark notes

(2) #pragma mark-notes

Third, the use of warning (note)

form of Use:

#warning code's not finished.

can help us to quickly locate the code

Iv. use of code blocks

For frequently used blocks of code, you can save it as a block of code and set the prompt for fast encoding.

Make appropriate edits to a block of code

Use and allow saved blocks of code not to be "written dead";

After setting the prompt effect:

Five, print content view (rewrite description method of skill)

code example:

-(NSString *) description{    //contains the object type name, and the object's pointer address    return [NSString stringwithformat:@ "" <@: p> {answer:%@ , Title:%@, Icon:%@, Options:%@} ", [Self class], self, self.answer, Self.title, Self.icon, self.options];}

Tips:

If you want to trace the details of an object at development time, you can override the description method, similar to the Java ToString ()

Add an extension to the root class

#import "Nsarray+log.h"

@implementation Nsarray (Log)

-(NSString *) Descriptionwithlocale: (ID) locale
{

Iterates through all the contents of the array, stitching the contents into a new string to return
nsmutablestring *STRM = [nsmutablestring string];

[StrM appendstring:@ "(\ n"];

Iterate through the array, self is the current array
for (id obj in self) {
When stitching a string, the description method of obj is called
[StrM appendformat:@ "\t%@,\n", obj];
}
[StrM appendstring:@ "];
return StrM;
}

@end

The last small summary of some shortcut keys, in fact, as long as you look at the actual operation after more than a few times, then do not rote, if you see here, and you can use these shortcuts in peacetime development, even if it is occasionally used, you can look more than the average developer! (The color section is often used for small series)
