After a while developing iOS Apps, i’ve discovered some frequently used shortcuts that make your life easier:
In iOS Simulator:
Alt+shift: double tap (two-finger tap), for scrolling etc.
Ctrl+Alt: Pinch (zoom-in / zoom-out).
Cmd+Shift+H: Device’s Home button press
Cmd+1, Cmd+2, Cmd+3: Rescale simulator to support different screen sizes
In Xcode:
Cmd+Alt+Shift+Left: Collapse all methods in file
Cmd+Alt+Left: Collapse current code block (Cmd+Alt+Right to expand)
Cmd+7: Shows all breakpoints (Cmd+A selects them all, backspace deletes)
some simple routinary Xcode tasks:
Create segue from an UIButton to another ViewController quickly using Storyboards:
1.- [Storyboard] Place an UIButton inside the current ViewController
2.- [Code] Create the IBOutlet in the .h file, implement it in the .m file
3.- [Storyboard] Ctrl+drag from UIButton to UIVIewController.
Create outlet inside ViewController (UILabel, UIButton, UITextView…)
1.- [Code] Create the property for the outlet in the .h file
Example: @property (weak, nonatomic) IBOutlet UIImageView *img;
2.- [SB] Place the UILabel, UIButton, etc. inside the ViewController (resize it, set its title, etc)
3.- [SB] Ctrl+drag from ViewController (yellow square on the bottom) to the UILabel, UIButton, … , select the attribute defined in step 1.
Create a progress bar (slightly different than the rest of the components)
1.- Place the UIProgressView inside the ViewController
2.- Create the @property in the .h file
3.- ctrl+drag from UIProgressView to an empty zone of the ViewController. Select the attribute specified in step 2
