- (void)setViewfinder:(CGFloat)left top:(CGFloat)top right:(CGFloat)right bottom:(CGFloat)bottom;
Parameters
left
: The distance (by percentage) between the left border of the viewfinder and the left side of the screen. The default value is 0.15.
top
: The distance (by percentage) between the top border of the viewfinder and the top side of the screen. The default value is 0.3.
right
: The distance (by percentage) between the right border of the viewfinder and the left side of the screen. The default value is 0.85.
bottom
: The distance (by percentage) between the bottom border of the viewfinder and the top side of the screen. The default value is 0.7.
Code Snippet
- Objective-C

[_dceView setViewfinder:0.1 top: 0.3 right: 0.9 bottom: 0.7];
_dceView = setViewfinder(0.1, top: 0.3, right: 0.9, bottom: 0.7)
Remarks
The viewfinder is built based on the screen coordinate system. The origin of the coordinate is the left-top point of the mobile device. The left border
of the viewfinder always means the closest border that parallels to the left side of the mobile device no matter how the mobile device is rotated.
